How To Choose A CPA In Idaho Falls: What To Look For And What To Avoid

How do you choose a CPA in Idaho Falls? Start with the license, not the price tag. The right CPA is verifiably licensed with the Idaho State Board of Accountancy, picks up the phone, and has actually handled situations like yours before, whether that is a straightforward return or a multistate business that needs a reviewed financial statement. The wrong one usually shows up as 1 of 5 predictable red flags below, and once you know what they look like, you can spot them before you ever sign an engagement letter.

CPA Vs. Tax Preparer Vs. Bookkeeper: Know What You Actually Need

Anyone can call themselves a "tax preparer." A bookkeeper handles the day-to-day: recording transactions, reconciling accounts, running payroll. A CPA is a different animal entirely. To earn the license, a Certified Public Accountant has to pass a brutal 4-part exam, rack up 150 semester hours of education, and log supervised work experience under a licensed CPA before Idaho will let them hang out a shingle. A tax preparer needs only an IRS-issued PTIN, a number with zero education or experience requirement attached to it.

That gap matters most when things stop being simple. A CPA can represent you in front of the IRS, sign off on audited or reviewed financial statements, and take on multistate tax questions that a preparer legally cannot touch. Bruce Denney and Kevin Killpack, the CPAs behind Poston Denney & Killpack, built their careers on that exact line: helping people figure out whether they need a bookkeeper for now or a CPA for good. If your situation is a simple W-2 return, a preparer might genuinely be enough. If you are running a business, filing in more than 1 state, or need financial statements a bank will actually trust, you need a CPA, full stop.

7 Things To Look For When Choosing A CPA In Idaho Falls

This is the real checklist for how to find a good CPA, not just any CPA.

1. An active, verifiable Idaho license. Every CPA practicing in Idaho is licensed through the Idaho State Board of Accountancy. Search their public license lookup by name or license number, or run the same check through CPAverify.org, the free national database maintained by NASBA. Either one will confirm the license is active and flag any disciplinary history. If a firm hesitates when you ask for a license number, that tells you plenty on its own.
2. Real experience with your specific situation, not just "taxes" in general. There is a real gap between a CPA who mostly handles individual returns and one who regularly prepares audited or reviewed financial statements for businesses operating in more than 1 state. Ask directly: how many clients do you currently serve with a situation like mine?
3. Continuity. You talk to the same people every time. Some firms rotate clients through whoever happens to be available that week. Ask who will actually be handling your account day to day, and whether that person changes year over year.
4. Fast, direct communication. This is the single biggest factor in whether a CPA relationship actually works. If a firm cannot return your call within a reasonable window before you have even signed anything, that is not going to magically improve once tax season hits.
5. Proactive planning, not just tax season scrambling. A CPA who only calls once a year, right before a deadline, is doing compliance work. A CPA who checks in throughout the year about entity structure, estimated payments, or upcoming changes to your situation is doing the job that actually saves you money.
6. Credentials beyond the base CPA license. Designations like the Certified Valuation Analyst (CVA) signal real specialization in business valuation that a general CPA license does not require on its own. Bruce Denney holds the CVA on top of his CPA, which is worth asking about directly if you are buying, selling, or valuing a business.
7. A track record you can actually check. Longevity is public record. Poston Denney & Killpack has been in Idaho Falls since 1984 and carries a BBB accreditation with an A+ rating, both of which are easy to verify in about 30 seconds. A firm that opened last year is not automatically a bad choice, but it is a different risk profile, and you should know that going in.

5 Red Flags To Avoid When Hiring A CPA

1. They cannot produce a license number, or get vague when you ask. Fastest way to weed out someone who has no business handling your finances.
2. They tie their fee, or even hint they might, to the size of your refund. This is not just a bad look; it violates IRS rules governing how CPAs and enrolled agents are allowed to charge for tax preparation. A firm suggesting it either does not know the rule or does not care, and neither one is a great look.
3. Callbacks take days, not hours, before you have even hired them. If that is how they treat a prospect, imagine how they treat a client who already signed.
4. They treat a multistate business or an audit-level engagement exactly like a basic individual return. Complexity earns a different level of attention. If a firm is not asking follow-up questions about your specific situation, they are not scoping the work correctly, and that catches up with you later.
5. Every question gets routed to someone who is not actually a CPA, with no way to reach the person signing your return. Junior staff support is normal, often a sign of a well-staffed firm. Never being able to reach the CPA accountable for your file is a different problem entirely.

The Cheapest Quote Isn't Always The Best Deal

It is tempting to shop a CPA the way you shop anything else: lowest number wins. Resist that if your situation has any real complexity to it. A rock-bottom quote in Idaho Falls usually means 1 of 2 things: a firm with more capacity than experienced staff to fill it, or a preparer who is not planning to spend much time on your file past data entry. Fine, if all you need is a basic return. Expensive, if you need someone who catches a filing issue before it becomes an IRS letter, helps plan a business sale, or actually shows up when things get complicated. Price matters. It just should not be the only thing on your checklist.

Questions To Ask Before You Hire A CPA

• Can you give me your Idaho CPA license number so I can verify it myself?
• Who will actually be preparing and signing my return or financial statements?
• How many clients do you currently serve with a situation similar to mine?
• What is your typical response time to calls or emails during tax season versus the rest of the year?
• Do you offer tax planning throughout the year, or only tax preparation once a year?
• What happens if I get a letter from the IRS after you have prepared my return?
• Can I see a sample engagement letter before I commit to anything?

FAQ: How To Choose A CPA In Idaho Falls

What is the difference between a CPA and a tax preparer in Idaho?

A CPA has passed a 4-part exam, completed 150 semester hours of education, and holds a license from the Idaho State Board of Accountancy. A tax preparer only needs an IRS-issued PTIN, which carries no education or experience requirement. CPAs can also represent you before the IRS and sign off on audited or reviewed financial statements, which most tax preparers cannot do.

What's the fastest way to find a good CPA in Idaho Falls?

Verify the license first, through the Idaho State Board of Accountancy or CPAverify.org, then ask 2 questions on the first call: how many clients they currently serve with a situation like yours, and how fast they typically return calls. A good CPA answers both without hesitation.

How do I verify a CPA's license in Idaho?

Search by name or license number directly through the Idaho State Board of Accountancy's public license lookup, or use CPAverify.org, the free national database maintained by NASBA. Both will show whether a license is active and flag any disciplinary history.

What should I look for in a CPA if my business operates in more than 1 state?

Look for a firm that can point to current clients with multistate operations, not just general business experience. Multistate tax questions involve nexus rules and apportionment issues that a CPA without recent, relevant experience can get wrong.

What are the biggest red flags when choosing a CPA?

The 5 biggest are an unverifiable license, any hint that fees are tied to your refund size, slow callbacks even before you hire them, treating complex situations the same as simple ones, and never being able to reach the actual CPA responsible for your file.

How much does a CPA cost in Idaho Falls?

Cost varies significantly based on the complexity of your return or engagement, whether you need audited or reviewed financial statements, and how many states are involved. A firm should be able to give you a clear scope and fee estimate after an initial conversation about your specific situation, not a flat rate quoted before they know anything about you.

When should I consider switching CPAs?

If you are consistently waiting days for a callback, getting passed to a different person every year with no continuity, or only hearing from your CPA once a year at tax time with no proactive planning, those are all reasonable reasons to have a conversation with a different firm.

CPA Vs. Tax Preparer: Why It Matters Who Does Your Taxes

In the debate over CPA vs. tax preparer, the real answer depends on what you actually need. A tax preparer can get your return filed. A Certified Public Accountant (CPA) can do that too, plus represent you in front of the IRS, audit financial statements, and help you plan ahead so next year's tax bill is smaller. If your finances are simple, a preparer is often enough. If you own a business, operate in more than one state, or need audited or reviewed financial statements, you need a CPA.

CPA Vs. Tax Preparer: What Is A Tax Preparer, Exactly?

"Tax preparer" is a broad term. It covers everyone from a seasonal worker at a retail tax franchise to an Enrolled Agent with 20 years of experience. By law, anyone who's paid to prepare federal tax returns needs a Preparer Tax Identification Number (PTIN), but beyond that, requirements vary widely. Some preparers hold no professional credential at all.

A good preparer can be a perfectly reasonable choice if your tax situation is straightforward: one job, standard deductions, no business income, no out-of-state complications. The IRS itself notes that most tax return preparers provide honest, professional service, but warns that taxpayers should still choose carefully, since the person who signs your return isn't the one who's ultimately responsible for it. You are.

What Is A CPA, And How Is It Different?

A CPA is licensed by a state board of accountancy, not just registered with the IRS. Earning the license requires passing the Uniform CPA Examination, a rigorous 16-hour, four-section test, plus meeting specific education requirements and completing ongoing continuing education every year to keep the license active. That licensing is what separates a CPA from a general tax preparer: it's a legal designation with accountability behind it, not just a job title.

In practice, that broader training means a CPA can do things a preparer typically can't:

• Represent you before the IRS in an audit, appeal, or collections matter
• Prepare audited or reviewed financial statements for lenders, investors, or buyers
• Advise on business structure, multistate tax exposure, and year-round tax planning, not just the return in front of them
• Take on the technical, high-stakes situations that a seasonal preparer isn't trained or licensed to handle

At Poston Denney & Killpack, that distinction shows up daily. Bruce Denney, CPA, CVA, brings over 20 years of public accounting and tax experience, and Kevin Killpack, CPA, has spent his career in accounting and management consulting for businesses of every size. That's the kind of bench strength a one-location tax franchise doesn't have.

When A Tax Preparer Is Genuinely Enough

There's no need to overpay for expertise you don't need. A tax preparer is a fine choice if:

• You have one source of income and no business or rental activity
• Your return is the same shape every year, with no major life changes
• You don't need representation, planning, or advisory work, just an accurate filed return

If that's your situation, a competent, credentialed preparer will likely serve you well.

When You Actually Need A CPA

The moment your finances stop being simple, the gap between a preparer and a CPA gets expensive fast. That's especially true if any of the following apply:

• You own or run a business. Business tax returns involve entity structure decisions, depreciation strategy, and deductions a preparer isn't trained to spot.
• You need audited or reviewed financial statements. Only a CPA can perform these. If a bank, investor, or buyer is asking for one, a preparer can't help you at all.
• You operate across state lines. Multistate tax returns require understanding how each state treats income, nexus, and apportionment differently. Get this wrong and you're looking at penalties in more than one jurisdiction.
• You're facing an IRS audit or notice. A CPA can represent you directly. Most preparers cannot.
• You're planning a business sale, acquisition, or major transaction. The tax consequences of these decisions are usually set well before you file anything, which means you need someone thinking ahead, not just filing behind.

This is exactly where business accounting and year-round tax planning earn their cost. A preparer files what already happened. A CPA helps make sure what happens next year is better.

What About Enrolled Agents And Tax Attorneys?

Two other credentials come up in this conversation, and it's worth knowing where they fit:

• Enrolled Agents (EAs) are licensed directly by the IRS and specialize specifically in tax matters. They can represent you before the IRS, similar to a CPA, but their scope is narrower: tax, not the broader accounting, audit, and financial statement work a CPA is trained for.
• Tax attorneys come in when there's a legal dimension: serious fraud allegations, tax court litigation, or communications you need protected by attorney-client privilege. For the vast majority of businesses and individuals, that level isn't necessary.

For most Southeast Idaho business owners, a CPA covers the full range of what's actually needed: filing, planning, representation, and financial statement work, all under one roof.

Red Flags To Watch For, Regardless Of Who You Hire

The IRS flags a few warning signs worth taking seriously no matter who prepares your return:

• A preparer who won't sign the return or include their PTIN
• Fees based on a percentage of your refund (this is a legal red flag, not just a bad deal)
• A preparer who isn't available once filing season ends, in case questions come up later
• Promises of an unusually large refund before they've even reviewed your documents

You're ultimately responsible for everything on your return, even if someone else prepares it. That alone is a good reason to choose carefully.

Why Southeast Idaho Businesses Choose Poston Denney & Killpack

Poston Denney & Killpack has been serving Idaho Falls and Southeast Idaho since 1984, and holds a BBB Accredited A+ rating. The firm is licensed in both Idaho and Oregon, which matters directly if your business has multistate exposure. What clients consistently point to isn't a sales pitch, it's responsiveness: calls get returned, and questions get answered by someone experienced enough to get to the right answer the first time, not passed down to whoever's available.

If your business needs tax preparation that accounts for what's ahead, not just what already happened, that's the kind of work a CPA firm is built for.

Frequently Asked Questions

What's the actual difference between a CPA and a tax preparer?

A CPA is licensed by a state board of accountancy after passing the Uniform CPA Exam and meeting education and continuing education requirements. A tax preparer only needs a PTIN from the IRS, with no exam or ongoing education required in most cases. That licensing gap is why CPAs can represent clients in IRS audits and prepare audited or reviewed financial statements, while most preparers cannot.

Is a tax preparer the same as an accountant?

Not necessarily. "Accountant" and "tax preparer" are both unlicensed, general terms anyone can use. A CPA is a specific, state-licensed credential that requires passing an exam and meeting ongoing requirements, which is what separates it from both terms.

How much more does a CPA cost compared to a tax preparer?

It depends heavily on the complexity of your return. For a simple individual filing, the difference may be minor. For a business return, multistate filing, or anything requiring financial statement work, a CPA's fee reflects work a preparer isn't licensed to do at all, so it isn't really an apples-to-apples comparison. The better question is what you actually need done, not just the lowest quote.

Is my tax preparer a CPA?

Not automatically. Every CPA can legally prepare tax returns, but not every tax preparer is a CPA. If you're not sure, ask directly, and ask to see their license number. A real CPA will have one.

What can a CPA do that a tax preparer can't?

A CPA can represent you before the IRS in an audit or appeal, prepare audited or reviewed financial statements, and advise on multistate tax exposure and business structure. Most tax preparers are limited to filing the return in front of them.

Do I need a CPA if I just have a simple personal return?

Not necessarily. If your finances are straightforward, a qualified tax preparer is often enough. A CPA becomes worth it once you own a business, operate in more than one state, or need planning and representation beyond just filing.

Have a return that's more complicated than a standard preparer can handle? Contact Poston Denney & Killpack or call (208) 522-0886 to talk with a CPA directly.

Year-End Tax Planning For Idaho Falls Business Owners: Start In September, Not December

Waiting until December to think about year-end tax planning means most of your best moves are already off the table. Equipment has to be purchased and placed in service, retirement plans have to be set up, and books have to be clean before December 31, and none of that happens in the last 2 weeks of the year. Idaho Falls business owners who start in September have 4 full months to make decisions instead of 4 panicked days.

Poston Denney & Killpack, PLLC has been guiding Idaho Falls business owners through exactly this kind of strategic tax planning since 1984, and BBB accredits the firm with an A+ rating. Here's what to actually do with the months you have left in 2026.

Why September Beats December For Tax Planning

Here's the math nobody spells out: your third quarter estimated tax payment is due September 15. That means by mid-September, you already have 3 quarters of real numbers, not guesses. You know roughly what the business made, what it's going to make, and how much tax you're on track to owe.

December gives you almost nothing extra. The calendar year ends in 2 weeks, most vendors and equipment dealers are backed up with other people's year-end purchases, and any retirement plan that has to be established (not just funded) by December 31 is already a scramble.

September planning means:

• Equipment purchases can be ordered, delivered, and placed in service before December 31, not rushed
• A new retirement plan can actually get set up in time to matter for 2026
• Your bookkeeping has time to get cleaned up so your CPA is working from real numbers, not estimates
• You have room to talk through decisions instead of making them under deadline pressure

The Idaho Bonus Depreciation Trap Most Business Owners Don't Know About

A lot of business owners believe that federal tax law now gives every business 100% bonus depreciation on equipment purchases. That's not the full picture in Idaho.

Under the One Big Beautiful Bill Act (OBBBA), Congress made 100% first-year bonus depreciation permanent for qualified property placed in service after January 19, 2025. That's real, and it applies on your federal return. But Idaho has decoupled from federal bonus depreciation rules since 2009, and Governor Little's signing of House Bill 559 in February 2026 did not change that. According to the Idaho State Tax Commission, Idaho still doesn't conform to bonus depreciation under IRC Section 168(k).

What this means in practice: if you buy a piece of equipment and take 100% bonus depreciation on your federal return, you'll need to add that deduction back on your Idaho return and instead depreciate the asset over its normal schedule for state tax purposes. Skip this step and you'll either underpay Idaho tax or get a notice asking why your state and federal depreciation don't match.

This is exactly the kind of detail that gets missed when business owners rely on national tax content instead of a CPA firm that knows Idaho law inside and out. Bruce Denney, CPA, CVA, has more than 20 years of public accounting and tax experience navigating these state-versus-federal gaps for local business owners.

What You Can Still Do With Section 179 In 2026

Here's the good news: Idaho does conform to Section 179, so this deduction works the same on your state and federal returns.

For tax years beginning in 2026, the Section 179 expensing limit is $2,560,000, with the phase-out threshold starting at $4,090,000, per IRS Revenue Procedure 2025-32. That's a substantial jump from where the limit sat before OBBBA raised it, and it's now a permanent, inflation-indexed part of the tax code rather than something that could get pulled back.

For most small and mid-sized Idaho Falls businesses, that ceiling is high enough that Section 179 covers the equipment, software, and qualifying improvements you'd realistically purchase in a year. Since Idaho recognizes Section 179 in full, this is often the more useful deduction to plan around locally, rather than counting on bonus depreciation to carry the state-side benefit. Kevin Killpack, CPA, works with Idaho Falls business owners on exactly this kind of business tax and advisory planning to make sure equipment purchases land in the right tax year.

Retirement Contributions: The Move With The Best Payoff

Retirement contributions are one of the few year-end moves that reduce your tax bill and build your own financial future at the same time.

For 2026, the IRS increased the 401(k) employee elective deferral limit to $24,500, up from $23,500 in 2025, with an additional $8,000 catch-up contribution available if you're 50 or older. Traditional and Roth IRA limits also increased, to $7,500 for 2026.

The timing matters here. A SEP-IRA can be opened and funded up until your tax filing deadline (including extensions), which gives you flexibility into 2027 for the 2026 tax year. A new 401(k) plan is a different story: it generally has to be established by December 31 to count for the current tax year, even if you fund it later. If you've been thinking about starting a retirement plan for yourself or your employees, September is the time to have that conversation, not December.

A September-To-December Tax Planning Checklist

1. Review 9 months of actual financial data. Pull your profit and loss for the year so far and project where you'll land by December 31.
2. Decide on equipment or software purchases. If you need it anyway, buying and placing it in service before year-end lets you use Section 179 on your Idaho return.
3. Evaluate retirement plan options. If you want a new 401(k) in place for 2026, start the paperwork now. SEP-IRAs have more flexibility but still benefit from early planning.
4. Reconcile your books. Clean, current bookkeeping is what lets your CPA give you real numbers instead of estimates when you sit down to plan. If your books aren't current, QuickBooks setup and support is worth tackling before your planning meeting, not after.
5. Confirm your entity structure still makes sense. If you're an LLC wondering whether an S-corp election would save on self-employment tax, year-end is the natural checkpoint to run the numbers.
6. Schedule a planning meeting with your CPA before Thanksgiving. Waiting until December means competing for time with everyone else who waited too.

Idaho-Specific Numbers To Know For 2026

• Idaho flat income tax rate: 5.3% for both individuals and corporations, effective for tax years beginning on or after January 1, 2025
• Idaho conforms to: Section 179 expensing, the federal standard deduction (as of House Bill 559), and most individual OBBBA provisions
• Idaho does not conform to: Section 168(k) bonus depreciation, or Section 168(n) qualified production property expensing
• Q4 2025 estimated tax deadline: January 15, 2026 (for reference on last year's cycle)
• Q3 2026 estimated tax deadline: September 15, 2026

Frequently Asked Questions

When should Idaho Falls business owners start year-end tax planning?
September is the ideal starting point. By mid-September, your third quarter estimated tax payment has already forced you to look at real year-to-date numbers, and you still have 3 and a half months to act on equipment purchases, retirement plan setup, and bookkeeping cleanup before December 31.

Does Idaho follow the federal 100% bonus depreciation rule?
No. While the One Big Beautiful Bill Act made 100% bonus depreciation permanent at the federal level for property placed in service after January 19, 2025, Idaho has decoupled from Section 168(k) bonus depreciation since 2009 and continues to do so under House Bill 559. Idaho business owners need to add back federal bonus depreciation and depreciate the asset separately on their Idaho return.

What is the Section 179 deduction limit for 2026?
For tax years beginning in 2026, the Section 179 expensing limit is $2,560,000, with the phase-out threshold beginning at $4,090,000, according to IRS Revenue Procedure 2025-32. Unlike bonus depreciation, Idaho fully conforms to Section 179, so this deduction applies the same way on both your federal and state returns.

What is Idaho's income tax rate for 2026?
Idaho has a flat income tax rate of 5.3% for both individual and corporate taxpayers, effective for tax years beginning on or after January 1, 2025.

How much can I contribute to a 401(k) or IRA before year-end 2026?
The 2026 401(k) employee elective deferral limit is $24,500, with an additional $8,000 catch-up contribution available for those 50 and older. Traditional and Roth IRA limits increased to $7,500 for 2026. A new 401(k) plan generally needs to be established by December 31 to count for the current tax year, so this decision benefits from early planning.

What's the difference between tax preparation and tax planning?
Tax preparation is filing an accurate return based on what already happened. Tax planning is making decisions before year-end, like equipment purchases, retirement contributions, and entity structure, that change what your return will show. Preparation looks backward; planning looks forward, and it only works if there's still time left in the year to act.

When is the deadline to set up a new retirement plan for 2026?
A new 401(k) plan generally must be established by December 31, 2026 to count for the 2026 tax year, even if you fund it later. A SEP-IRA is more flexible and can typically be opened and funded up until your tax filing deadline, including extensions.

When Should You Hire A CPA? 6 Signs It's Time

The short answer: if your taxes have gotten more complicated than a W-2 and a standard deduction, or your business has grown past the "I'll figure it out myself" stage, it's time to hire a CPA. That includes starting a business, taking on self-employment or rental income, getting an IRS letter, going through a major life change, or realizing your books are a mess. A CPA does more than file a return; a good one saves you money and keeps you out of trouble year-round.

Most people don't think about hiring a CPA until tax season is already stressing them out. By then you're reacting instead of planning, and reacting is usually the more expensive option. Here are 6 signs it's time to bring in a CPA, and what that relationship actually looks like once you do.

Do You Need A CPA, Or Will Tax Software Work?

Tax software is built to fill in boxes based on what you tell it. A Certified Public Accountant is licensed by the state, tested extensively on tax law and accounting standards through exams recognized by the American Institute of CPAs (AICPA), and trained to look at your full financial picture, not just last year's numbers. A CPA can spot deductions you didn't know existed, flag a business structure that's costing you money, and give you a plan before decisions get made instead of a form after they're finalized.

That distinction matters most in the 6 situations below.

Sign 1: You Started A Business Or Changed Its Structure

Choosing between a sole proprietorship, LLC, or S-corp affects how much you pay in taxes, how much liability protection you have, and how complicated your filing becomes with both the IRS and the Idaho State Tax Commission. Getting this wrong at the start is expensive to fix later. Our business formation services walk you through the tradeoffs before you file paperwork with the state, not after.

Sign 2: You Have Self-Employment, Freelance, Or Rental Income

The moment income stops coming from a single W-2, your tax situation changes. Quarterly estimated payments, self-employment tax, depreciation on rental property, and business expense tracking all become your responsibility. This is exactly where DIY software tends to miss deductions or, worse, trigger errors that catch the IRS's attention.

Sign 3: You Received An IRS Letter Or Are Facing An Audit

An IRS notice does not automatically mean something is wrong, but it does mean you need someone who knows how to respond correctly and on time. A CPA can read the letter, tell you what it actually means, and provide IRS representation if it comes to that. Handling it yourself, or ignoring it, is how a small issue turns into a bigger one.

Sign 4: You Went Through A Major Life Change

Divorce, inheritance, selling a home, a new baby, or the death of a family member all carry tax consequences most people don't see coming. These are one-time events with permanent tax implications, and they're exactly the kind of situation where a generic software prompt won't ask the right follow-up questions. A CPA will.

Sign 5: Your Bookkeeping Is A Mess Or Doesn't Exist

If you're a business owner and you couldn't tell someone your current profit and loss without digging through a shoebox of receipts, that's a sign. Clean, current books are what let a CPA actually plan ahead for you instead of just reconstructing your year every April. Our bookkeeping and QuickBooks support is usually the fastest fix here, and often the first thing we help a new client set up.

Sign 6: You're Making Decisions With Tax Consequences You Haven't Thought Through

Buying a second property, taking money out of a retirement account early, expanding a business into a new state, selling a business. Each of these carries a tax bill that's much easier to plan around before the decision than after. If you're about to make a financial move and you're not sure what it will cost you at tax time, that question alone is a sign you need a CPA in the conversation now, not next April.

What A CPA Relationship Actually Looks Like

Hiring a CPA does not mean an expensive retainer or losing control of your finances. For most individuals and small businesses, it means a point of contact who prepares your return, provides year-round tax planning, and flags issues before they become expensive. At Poston Denney & Killpack, that has meant the same thing since 1984: personal attention from a CPA who actually knows your situation, not a rotating cast of junior staff.

Frequently Asked Questions

Do I need a CPA or can I just use tax software?

Tax software works well if your income is a single W-2 and you take the standard deduction. Once you add self-employment income, rental property, a business, or a major life change, a CPA is worth the cost because the deductions and rules involved are easy to miss on your own.

How much does it cost to hire a CPA?

Cost depends on the complexity of your return and the services you need, from a simple tax filing to ongoing bookkeeping and business advisory work. Poston Denney & Killpack has built its reputation in Idaho Falls partly on offering affordable rates without cutting corners on service.

What is the difference between a CPA and a regular accountant or tax preparer?

A CPA is licensed by the state and has passed rigorous exams and continuing education requirements. A general tax preparer or bookkeeper may not carry that license, which matters if you ever need someone to represent you in front of the IRS or advise you on complex tax strategy.

When during the year should I hire a CPA, not just at tax time?

The earlier the better, especially if you are starting a business, changing its structure, or going through a major life event. Waiting until tax season means a CPA is reacting to decisions you already made instead of helping you plan them.

Can a CPA help if I already got a letter from the IRS?

Yes. A CPA can read the notice, explain what it actually means, and communicate with the IRS on your behalf. Responding quickly and correctly is important, so this is not something to sit on.

Do I need a CPA if I only have a small side business?

Even a small side business creates self-employment tax obligations and often quarterly estimated payments. A CPA can set up simple, sustainable habits early so the business stays organized as it grows, instead of untangling a mess later.

IRS Installment Agreement: What It Is, How It Works, And Whether It's A Good Idea

An IRS installment agreement is a monthly payment plan that lets you pay off tax debt over time instead of all at once. Most individuals who owe $50,000 or less and have filed all required returns can set one up online in minutes. It will not stop interest from accruing, but it does stop the IRS from pursuing liens, levies, or wage garnishment while the plan is active. Whether it is a good idea depends on how much you owe, how fast you can pay, and whether your situation is simple enough to handle yourself.

If you have opened a letter from the IRS and felt your stomach drop, you are not alone. Tax debt is more common than most people think, and the IRS actually prefers to work out a payment plan rather than chase you through collections. Here is what an installment agreement really involves, what it costs in 2026, and how to decide if it is the right move.

What Is an IRS Installment Agreement?

An installment agreement is a formal arrangement with the IRS to pay a tax balance over time instead of in one lump sum. The authority for these agreements comes from Internal Revenue Code Section 6159, and the IRS has offered some version of this program for decades. In practice, it means you agree to a monthly payment amount, and as long as you keep paying, the IRS generally will not file a lien, levy your bank account, or garnish your wages.

It is not a settlement. You still owe the full amount, plus interest and penalties that continue to accrue until the balance is paid off. Think of it as buying breathing room, not forgiveness.

The Types of IRS Payment Plans

The IRS offers a few different structures depending on how much you owe and how quickly you can pay:

• Pay in full: No setup fee, no future interest once paid, and you can do it online, by phone, or by mail.
• Short-term payment plan: For balances under $100,000 in combined tax, penalties, and interest, paid within 180 days. No setup fee, but interest and penalties keep accruing until it is paid off.
• Long-term payment plan (the traditional "installment agreement"): For balances of $50,000 or less, paid monthly. This is what most people mean when they say "IRS installment agreement."

Within the long-term option, you can choose Direct Debit (automatic payments pulled from your bank account) or a non-Direct Debit plan where you pay manually each month. Direct Debit costs less to set up and is generally the safer choice, since missed manual payments are one of the most common reasons agreements default.

One more thing worth knowing: for years, individuals with lower balances could qualify for what was called a Streamlined Installment Agreement. In March 2025, the IRS replaced that name with the Simple Payment Plan, which now allows qualifying individuals with $50,000 or less in assessed tax, penalties, and interest to pay through the remaining collection period, generally up to 10 years from assessment. If you see "streamlined installment agreement" referenced elsewhere, know that it is the same basic idea under a new name and, in some cases, slightly more generous terms.

What Does an IRS Installment Agreement Cost in 2026?

Fees depend on how you apply and which payment method you choose, based on current IRS.gov figures:

• Direct Debit, applied online: $29 setup fee
• Direct Debit, applied by phone, mail, or in person: $107 setup fee
• Non-Direct Debit, applied online: $69 setup fee
• Non-Direct Debit, applied by phone, mail, or in person: $178 setup fee
• Low-income taxpayers: setup fee waived for Direct Debit, or reduced to $43 for non-Direct Debit (may be reimbursed once the plan is complete)

On top of the setup fee, interest and any applicable failure-to-pay penalties continue to accrue until the balance is paid in full. That is the part people are often surprised by. An installment agreement stops aggressive collection, not the meter running on what you owe.

How to Apply

Individuals who owe $50,000 or less and have filed all required returns can typically apply online through their IRS Online Account. If you do not qualify online or prefer not to, you can apply by phone, by mail, or in person using Form 9465, Installment Agreement Request. Some situations, such as balances over $50,000 or unfiled returns, will require a more detailed financial disclosure using Form 433-F before the IRS approves a plan.

What Happens if You Miss a Payment

Defaulting on an installment agreement means the IRS can resume collection activity, including liens and levies, and may charge a reinstatement fee to get the plan back on track. If a payment is going to be late or you cannot make the amount you agreed to, contact the IRS before you miss it. Plans can often be revised online, including changing your monthly amount or due date, which is a much better outcome than letting it lapse.

Is an IRS Installment Agreement a Good Idea?

For a lot of people, yes. It stops the IRS from taking aggressive action, gives you a predictable monthly number to plan around, and is far less disruptive than a lien or levy. It makes the most sense when:

• You have filed all required returns and just cannot pay the full balance
• Your balance is under $50,000 and you can reasonably commit to a monthly payment
• You want to avoid liens, levies, or wage garnishment while you catch up

Where it gets more complicated is when you owe more than $50,000, have unfiled returns, have already defaulted on a prior agreement, or think you might qualify for a partial payment installment agreement or an offer in compromise instead. Those situations involve financial disclosure and IRS judgment calls that are worth having someone experienced walk through with you before you apply, since the wrong plan type or a rejected application can cost you time you do not have.

This is where IRS problem resolution becomes its own specialty rather than a box to check. Bruce Denney, CPA and CVA, has spent more than 20 years handling exactly these situations for clients across Idaho Falls, and knows which plan type actually fits a given balance versus which one just sounds right on paper.

A Note for Idaho Taxpayers

If you owe both the IRS and the state of Idaho, know that these are two completely separate processes. The Idaho State Tax Commission runs its own payment plan system through the Taxpayer Access Point (TAP), and setting up an IRS installment agreement does nothing to address an Idaho balance, or vice versa. Idaho's plans have their own rules, including different timelines and eligibility requirements than the IRS. If you are dealing with both at once, it is worth having someone look at the whole picture rather than tackling them one at a time on your own.

Poston Denney & Killpack has been sorting out situations like this for Idaho Falls clients since 1984. If you are behind on federal or Idaho taxes and want a straight answer on your options, our tax planning team can walk through what an installment agreement, a partial payment plan, or another option would actually look like for your situation. For more complex cases involving IRS notices or ongoing collection issues, our IRS representation services handle the negotiation directly so you are not doing it alone. And if you are just trying to get your tax prep caught up before any of this matters, our tax preparation services are the place to start.

Frequently Asked Questions

How Long Can an IRS Installment Agreement Last?

Long-term individual plans, now called Simple Payment Plans, generally allow payments through the IRS's remaining collection period, which can run up to 10 years from the date the tax was assessed. Older guidance references a 72-month standard, so the exact length depends on your balance and when it was assessed.

Does the IRS Still Call It a "Streamlined Installment Agreement"?

No, not for individuals. In March 2025, the IRS replaced the individual Streamlined Installment Agreement with the Simple Payment Plan. The core idea, a lower-disclosure payment plan for balances of $50,000 or less, is the same, but the name and some terms have changed.

Will an Installment Agreement Stop IRS Collection Actions Like Liens or Levies?

Generally, yes. Once a payment plan is approved, the IRS typically will not pursue enforced collection, such as levies, while the plan is in effect and payments are being made. It does not erase a lien that has already been filed.

Does Interest Keep Accruing While I'm on a Payment Plan?

Yes. Interest and any applicable penalties continue to add to your balance until it is paid in full. An installment agreement changes how you pay, not how much interest accrues along the way.

What Happens if I Miss a Payment on My Installment Agreement?

Missing a payment can put your agreement into default, which allows the IRS to resume collection efforts and may add a reinstatement fee. Contact the IRS as soon as you know a payment will be late, since plans can often be revised before they default.

Is an IRS Installment Agreement Separate From an Idaho State Tax Commission Payment Plan?

Yes. The IRS and the Idaho State Tax Commission run completely separate payment plan systems. If you owe both, you need to apply with each agency individually.

IRS Audit Statue Of Limitations: How Long Does The IRS Have To Come After You?

The IRS generally has 3 years from the date you file to audit your tax return. That window stretches to 6 years if you leave off more than 25% of your gross income, and there is no time limit at all if you never file a return or file a fraudulent one. Idaho has its own 3-year audit window for state tax returns, with a similar set of exceptions. Knowing which clock applies to your situation tells you exactly how long to keep your records and when you are actually in the clear.

If you have ever wondered whether an old tax return could still come back to bite you, you are not alone. The IRS audit statute of limitations is one of the most misunderstood parts of the tax code, partly because there is not just 1 rule. There are 3, and which 1 applies to you depends on what was on your return (or whether you filed one at all).

The 3-Year Rule: How Long The IRS Usually Has To Audit You

For the vast majority of taxpayers, the IRS has 3 years from the date you file your return, or the due date of the return, whichever is later, to open an audit and assess additional tax. The IRS calls this the Assessment Statute Expiration Date, or ASED.

• If you filed your 2022 return on the April deadline, the IRS generally has until that same date in 2026 to audit it.
• If you filed late with no extension, the 3-year clock starts on the date you actually filed, not the original due date.
• If you got an extension and filed by the extended deadline, the clock still starts from the due date, not your early or on-time filing date within the extension window.

Once that 3-year window closes, the IRS generally cannot open a new audit or assess more tax on that return. This is why keeping 3 years of tax records is the baseline every CPA recommends, though there are good reasons to hold onto some documents longer, covered below.

When The IRS Gets 6 Years Instead Of 3

The 3-year rule doubles to 6 years if you omit more than 25% of your gross income from a return. This does not have to be intentional. If you earned $200,000 and only reported $140,000, for example, that 30% gap is enough to trigger the extended window even if the omission was a genuine mistake.

The 6-year rule also applies if you failed to report more than $5,000 in gross income from foreign financial assets, such as interest from an overseas bank account. This lines up with the reporting period for FBAR (foreign bank account report) filings, which carry their own steep penalties for noncompliance.

Note that overstating deductions or credits, as opposed to omitting income, does not trigger the 6-year rule. That distinction has actually been tested in court, and the extended statute only applies to unreported income, not inflated write-offs.

When There Is No Time Limit At All

In 3 specific situations, the statute of limitations never starts running, which means the IRS can audit you at any time, with no expiration date:

1. You never filed a return. No filing means no clock. The IRS can assess tax on unfiled years indefinitely.
2. You filed a false or fraudulent return with intent to evade tax. Fraud removes the time limit entirely.
3. You did not sign your return. An unsigned return is not considered valid by the IRS, so the 3-year period never begins.

If the IRS never received a valid, signed return for a given year, that year effectively stays open forever. This is one of the clearest reasons to always file, even if you cannot pay what you owe. An imperfect return that starts the clock is almost always better than no return at all.

What Actually Starts The Clock

A lot of confusion around this topic comes down to 1 question: which date counts as day 1? The rule is the later of 2 dates: the original due date of the return, or the date you actually filed it.

• File on time (or early): the clock starts on the due date.
• File with an approved extension, by the extended deadline: the clock starts on the original due date, not the extended one.
• File late with no extension: the clock starts on the date you actually filed.

This matters most for people who file late. A return filed 2 years after the deadline does not give the IRS 5 years of runway (3 plus the 2-year delay); it gives them 3 years from the actual, late filing date.

Can The Statute Of Limitations Be Extended?

Yes, but only with your agreement. If an audit is underway and the IRS needs more time to finish reviewing your return before the statute expires, an auditor may ask you to sign Form 872, Consent to Extend the Time to Assess Tax. You are allowed to negotiate the length of the extension, limit it to specific issues, or decline to sign altogether. Refusing does not stop the audit, but it does force the IRS to work within whatever time remains on the original 3-year clock, which sometimes prompts a faster resolution.

This is exactly the kind of decision where having a CPA in your corner during the audit, rather than navigating it alone, makes a real difference. Our IRS representation services exist for exactly this situation, and our tax planning team can also help you get ahead of issues before they trigger a longer look-back period in the first place.

Idaho's Audit Statute Of Limitations: What Is Different At The State Level

Most articles on this topic stop at the federal rules and never mention that Idaho runs its own, separate clock. For Idaho Falls taxpayers and business owners, both timelines matter.

• Idaho income tax: The Idaho State Tax Commission generally has 3 years from the later of the filing date or due date to issue a notice of deficiency, mirroring the federal rule.
• Federal audit adjustments reopen the Idaho clock: Under Idaho Code 63-3068(f), if a federal audit changes your taxable income, Idaho's period to assess additional state tax reopens and does not expire until 1 year after you report that federal change to the state, or 3 years from your original filing date, whichever is later. In other words, an IRS audit can indirectly extend your exposure at the state level.
• Idaho sales and use tax: The standard statute is also 3 years from the filing or due date, but it stretches to 7 years if no sales tax return was ever filed for the period in question.

If you have been through a federal audit that resulted in changes to your reported income, do not assume the matter is closed once the IRS finishes. Idaho may still have an open window to review your state return as a result. A tax preparation review can catch these overlaps before they become a second audit.

How Long You Should Actually Keep Your Tax Records

Given all of the above, here is a practical, no-guesswork breakdown for how long to hang onto your documents:

• 3 years: The baseline for most individual and business returns, in line with the standard federal and Idaho assessment periods.
• 6 years: If you have income sources that could plausibly be underreported by more than 25%, such as self-employment income, rental income, or investment gains, or if you hold foreign financial accounts.
• 7 years: Records related to a bad debt deduction or a loss from worthless securities.
• Indefinitely: Any year you did not file a return, filed a fraudulent return, or never signed a return. Also keep records tied to property (like your home or investments) for as long as you own the asset, plus the applicable statute period after you sell it.

Frequently Asked Questions

How Long Does The IRS Have To Audit You After You File?

The IRS generally has 3 years from the date you file your return, or its due date, whichever is later. This extends to 6 years if you omit more than 25% of your gross income, and there is no limit if you never filed or filed fraudulently.

Can The IRS Audit You After 7 Years?

In most cases, no. The standard window is 3 years, extended to 6 for substantial income omissions. Beyond 7 years, an audit is unlikely unless the return involved fraud or was never filed, in which case there is no expiration at all.

Does Filing An Extension Change The Audit Statute Of Limitations?

No. Filing with an extension and submitting your return by the extended deadline still starts the 3-year clock on the original due date, not the extension date.

What Happens If I Never Filed A Tax Return For A Past Year?

The statute of limitations never starts running for a year with no filed return, which means the IRS can assess tax for that year at any time. Filing a late return, even years after the fact, starts the clock and limits your long-term exposure.

Is Idaho's Audit Statute Of Limitations The Same As The IRS's?

They are similar but not identical. Idaho generally follows a 3-year rule for income tax, but a federal audit that changes your reported income can reopen Idaho's assessment window under Idaho Code 63-3068(f), and unfiled sales tax returns carry a 7-year statute rather than 3.

Should I Sign An Extension If The IRS Asks Me To During An Audit?

It depends on the situation. You are allowed to negotiate the terms, limit the scope, or decline. This is a decision worth making with a CPA who can weigh what is actually at stake in your specific audit before you sign anything.

How Long Should I Keep My Tax Records?

Keep records for at least 3 years for most returns, 6 years if you have income that could be underreported by more than 25% or foreign accounts, 7 years for bad debt or worthless securities claims, and indefinitely for any year you did not file or filed fraudulently.

Worried About An Audit Or An Old Return? Let's Look At It Together

Statute of limitations questions rarely come up in the abstract. Usually they come up because you got a letter, you are worried about an old return, or you are not sure how long to keep a box of records taking up space in your closet. Poston Denney & Killpack has been helping Idaho Falls individuals and businesses sort through exactly these situations since 1984, and we would rather look at your specific numbers than guess. If you are facing an audit or just want a second set of eyes on your filing history, call us at (208) 522-0886 or reach out through our IRS representation page to schedule a conversation.

Got An IRS Letter? Here's What To Do First (And What Not To Do)

TLDR: If you received a letter from the IRS, do not panic and do not ignore it. Read it carefully, find the notice or letter number in the top right corner, and check the response deadline. Most letters deal with a routine issue like a math correction, a missing form, or a balance due, not an audit. If the letter involves an audit, a large balance, identity verification, or wording you don't fully understand, call a CPA before you respond.

Why The IRS Sent You A Letter In The First Place

An IRS letter in the mailbox feels like bad news before you even open it, but most of them aren't. The IRS sends letters and notices for dozens of routine reasons: a math error on your return, income that doesn't match what an employer reported, a request to verify your identity, or a simple balance due. Every letter has a notice or letter number printed in the upper right corner, things like CP2000, CP14, or 5071C, and that code tells you exactly why the IRS is contacting you.

• CP2000: the income or deductions on your return don't match what a third party (like an employer or bank) reported
• CP14: you have a balance due on your account
• 5071C: the IRS needs to verify your identity before processing your return
• LT11: a more serious collection notice, often a final warning before a levy

You can look up any notice number directly on the IRS's own notice and letter lookup page to see exactly what it means before you do anything else.

What To Do First When You Get An IRS Letter

• Read the whole letter before reacting. The notice number, tax year, and reason for contact are usually on the first page.
• Check the response deadline. Most IRS letters give you 10 to 30 days to respond, and that date is printed directly on the notice.
• Compare it to your tax return. If the letter references a correction, pull your copy of that year's return and check the numbers side by side.
• Note whether it's informational or actionable. Some letters just tell you something changed. Others require a specific response, a payment, or documentation by the deadline.
• Keep the original and make copies. You'll want the letter on hand if you call the IRS, a CPA, or both.

What Not To Do When You Get An IRS Letter

A lot of people assume any letter from the IRS means they're being audited or that they need to pay immediately to avoid getting in trouble. That's not accurate, and acting on that assumption is how simple notices turn into bigger problems.

• Don't ignore it. Unpaid balances keep accruing interest and penalties, and missed deadlines can forfeit your right to dispute a notice you don't agree with.
• Don't assume the IRS is automatically right. Notices are frequently based on incomplete information. If something looks off, you're allowed to push back.
• Don't call a number from a text or email claiming to be the IRS. The IRS makes first contact by mail, not by phone, text, email, or social media. Any unexpected call or message demanding immediate payment is almost always a scam.
• Don't send payment or personal information before verifying the letter is legitimate. See the next section for how to check.

How To Tell If An IRS Letter Is Actually Legit

Real IRS letters share a few consistent features: they arrive by mail, include a notice or letter number in the top corner, reference a specific tax year, and never demand payment through gift cards, wire transfers, or cryptocurrency. If a letter pressures you to pay immediately using an unusual payment method, threatens arrest, or arrived by text or email instead of mail, it's a scam. When in doubt, look up the notice number on IRS.gov's official guidance page or call your CPA to verify before responding to anything.

When It's Time To Call A CPA Instead Of Handling It Alone

This is exactly where a lot of taxpayers get themselves into more trouble than they started with. IRS auditors are trained to gather more information than you're actually required to provide, and going it alone to avoid a representation fee often ends up costing more once a deficiency bill shows up. If your letter is an audit notice, our IRS audit representation service means you forward the notice to us and we handle the process from there, so you're not taking time off work or losing sleep over paperwork. Bruce Denney, CPA and CVA, and Kevin Killpack, CPA, have represented Idaho Falls taxpayers through IRS audits since the firm opened in 1984. If the notice involves a spouse or ex-spouse's filings instead, our innocent spouse relief services may be the better fit.

Frequently Asked Questions

What does it mean if I get a letter from the IRS?
Most IRS letters address a routine issue such as a math error, a missing form, identity verification, or a balance due. It does not automatically mean you're being audited. Each letter has a notice or letter number, such as CP2000 or CP14, in the top right corner that identifies the exact reason for contact.

How long do I have to respond to an IRS letter?
Most IRS letters give taxpayers 10 to 30 days to respond, and the specific deadline is printed directly on the notice. Missing that date can add penalties and interest or limit your right to dispute the notice, so check the date the moment the letter arrives.

Is it normal for the IRS to contact me by mail?
Yes. The IRS almost always makes first contact by mail, not by phone, email, text, or social media. If you receive a call, text, or email claiming to be the IRS demanding immediate payment, treat it as a scam, even if the caller ID looks official.

What if I don't understand why I received the letter?
Look up the notice or letter number on IRS.gov's notice lookup page, which explains what each code means in plain language. If it's still unclear after that, or the letter references an audit, a large balance, or identity verification, contact a CPA before responding on your own.

Do I need to hire a CPA for every IRS letter?
No. A simple notice about a math correction or a small balance can often be handled by following the instructions on the letter itself. A CPA becomes worth involving when the letter involves an audit, a large balance, identity theft, or wording you don't fully understand, since a wrong response can create a bigger problem than the original letter.

What happens if I ignore an IRS letter?
Ignoring an IRS letter is one of the costliest mistakes a taxpayer can make. Unpaid balances continue to accrue interest and penalties, and unresolved audits or notices can escalate to liens, levies, or wage garnishment. Even if you disagree with the letter, responding by the deadline preserves your right to dispute it.

Got A Letter You're Not Sure About?

If an IRS letter landed in your mailbox and you're not sure whether it's routine or something bigger, don't sit on it until the deadline. Call Poston Denney & Killpack at (208) 522-0886 and we'll help you figure out exactly what it means and what to do next.
