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.

Bookkeeper vs CPA: Here's How to Tell Which One You Need

A bookkeeper keeps your day to day financial records accurate: entering transactions, reconciling accounts, and making sure your books are ready when tax season hits. A CPA is licensed to prepare and sign tax returns, represent you before the IRS, and advise on tax strategy and bigger financial decisions, work a bookkeeper legally cannot do. Most Idaho Falls business owners need CPA guidance the moment taxes, growth, or an IRS letter enter the picture, with bookkeeping running underneath as the ongoing support that keeps that guidance accurate. Plenty of businesses use both, handled by the same firm.

If you have ever typed "bookkeeper vs cpa" into Google at 11pm while staring at a shoebox of receipts, you are not alone. The two roles get lumped together constantly, and the confusion is expensive: hire a CPA to do data entry and you are paying $200 an hour for work a bookkeeper handles for a fraction of that. Skip the CPA when you actually need one and you risk a missed deduction, a penalty, or an IRS notice you do not know how to answer.

What Does a Bookkeeper Actually Do?

A bookkeeper is the person keeping your financial data clean on an ongoing basis. That typically includes:

• Recording daily sales, expenses, and payments
• Reconciling bank and credit card statements
• Tracking accounts payable and receivable
• Running payroll
• Producing monthly financial reports for your own use

Bookkeepers are not required to hold a license. Many pursue voluntary credentials like the Certified Bookkeeper designation through the American Institute of Professional Bookkeepers, but there is no state licensing board involved, and no legal requirement to hold one to practice.

What Does a CPA Actually Do?

A Certified Public Accountant holds a state issued license. In Idaho, the Idaho State Board of Accountancy requires 150 semester hours of college education, passing the Uniform CPA Exam, and supervised experience under another licensed CPA before the license is granted. CPAs also complete continuing education every year to keep it active. This is really an accountant vs cpa distinction at its core: a CPA is a specific, licensed type of accountant, while plenty of people who call themselves accountants have never taken the exam.

That license unlocks work a bookkeeper legally cannot do:

• Representing you before the IRS in an audit, appeal, or collections matter under IRS Circular 230 (bookkeepers have very limited representation rights, and only for returns they personally prepared)
• Preparing reviewed or audited financial statements for a bank or investor
• Strategic tax planning, not just tax filing
• Advising on business structure, major purchases, or growth decisions with real tax consequences

A CPA can also do everything a bookkeeper does. In practice, most CPAs delegate the daily data entry to a bookkeeper and focus their time on the higher stakes work their license is actually for.

The Questions That Actually Tell You Which One You Need

Skip the personality quiz version of this decision. Ask yourself these instead:

• Have you gotten a letter from the IRS? That is a CPA conversation immediately. A bookkeeper cannot negotiate with the IRS on your behalf.
• Are you just trying to stay organized, or are you trying to reduce what you owe? Staying organized is bookkeeping. Reducing your tax bill through timing, structure, or planning is CPA territory.
• Is your business structure getting more complicated? A single member LLC with a handful of transactions a month often runs fine with lighter bookkeeping support. An S-corp, multiple revenue streams, or employees usually benefits from CPA involvement.
• Do you need financial statements a bank or investor will actually trust? Bookkeepers generally cannot prepare reviewed or audited statements. That requires a CPA.
• Are your books currently a mess? That is not a reason to shop for a separate discount bookkeeper. A CPA firm that also handles bookkeeping can clean up months of uncategorized transactions under the same roof that will eventually prepare your return, which avoids paying twice to hand records off between two vendors.

What It Costs: Bookkeeper vs CPA

Bookkeeping services commonly run in the range of $250 to $700 a month depending on transaction volume, or $40 to $80 an hour for freelance bookkeepers. CPA rates typically run $150 to $400 an hour, with monthly retainers for ongoing CPA services often landing between $600 and $2,000 or more depending on the complexity of the work.

The costlier mistake is usually the quiet one: staying with bookkeeping alone once a business has outgrown it. A missed deduction, the wrong entity structure, or an unanswered IRS notice runs well past the difference between a bookkeeper's rate and a CPA's. Paying CPA rates for routine data entry is inefficient too, which is exactly why a firm that offers both can fold bookkeeping into the relationship instead of billing every task at CPA rates.

You Do Not Have to Choose One Firm for Bookkeeping and Another for CPA Work

Poston Denney & Killpack, in business in Idaho Falls since 1984, offers both under one roof, which is the piece most comparison guides leave out entirely: they assume you are shopping two separate vendors. A lot of Idaho Falls business owners start with QuickBooks setup and bookkeeping support and add CPA level tax planning and IRS representation as the business grows, without switching firms or re-explaining their history to someone new. You can see the full range of business accounting services PDK provides, from day to day bookkeeping through audit and advisory work.

When You Need Both

Most growing businesses eventually use a bookkeeper and a CPA together, not instead of each other. The bookkeeper keeps the data clean all year. The CPA uses that clean data to file accurately, plan ahead, and step in if the IRS ever comes calling. Trying to skip the bookkeeping layer usually means your CPA spends billable hours cleaning up records instead of doing the strategic work you are actually paying for.

Frequently Asked Questions

Can a bookkeeper prepare my tax return?

A bookkeeper can prepare a tax return if they hold a Preparer Tax Identification Number, but they cannot represent you before the IRS in an audit or dispute, and they typically do not provide tax planning or strategy. For anything beyond a straightforward filing, a CPA is the safer choice.

Is an accountant the same as a CPA?

No. "Accountant" is a general title anyone can use, while "CPA" refers specifically to someone who passed the Uniform CPA Exam and holds a state license. All CPAs are accountants, but not all accountants are CPAs.

How do I know if my books are too messy for a bookkeeper to fix?

They are not. Cleaning up disorganized or out of date books is exactly what a bookkeeper does, regardless of how far behind things have gotten. The more overdue the cleanup, the more it costs to wait.

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

Filing taxes accurately, even for a small side business, is CPA territory the moment self-employment tax, quarterly estimates, or real deductions get involved. Day to day bookkeeping needs are usually lighter at that stage, but most owners find it easier to have both handled by the same firm from the start rather than outgrowing a standalone bookkeeper later and having to switch.

What happens if I use a bookkeeper and then get audited?

A bookkeeper has very limited representation rights and generally cannot negotiate with the IRS on your behalf. You would need to bring in a CPA, enrolled agent, or attorney at that point, which is why many businesses prefer having a CPA relationship in place before an audit happens.

Can I switch from a bookkeeper to a CPA later without starting over?

Yes, and it is common. The cleaner your books are when you make the switch, the faster a CPA can pick up where the bookkeeper left off. Working with a firm that offers both makes that transition simpler since your history and records stay in one place.

Ready to Figure Out Which One You Need?

Poston Denney & Killpack has been sorting out exactly this question for Idaho Falls business owners since 1984. Call (208) 522-0886 and talk through your specific situation with someone who can tell you straight whether you need a bookkeeper, a CPA, or both.

S-Corp Vs. LLC In Idaho: Which One Actually Saves You More In Taxes?

Short answer: if your business nets more than about $40,000 to $50,000 a year after paying yourself a fair salary, electing S corp tax status on your LLC will likely save you money on self employment tax. Below that, the LLC's simplicity usually wins. In Idaho specifically, the math tilts slightly further in the LLC's favor at the low end, since Idaho's flat 5.3% income tax and $100 formation fee already keep costs low no matter which way you go.

"Should I be an LLC or an S corp?" is the wrong question. Here is the real one: should your LLC elect to be taxed as an S corp? An LLC is a legal structure. An S corp is a tax election. You can have both at once, and most small business owners in Idaho Falls who benefit from S corp taxation do exactly that.

Here is how the numbers actually break down, what it costs to make the switch, and where Idaho's tax rules change the calculation. If you would rather have someone run your actual numbers than estimate from an article, our business tax planning services cover exactly this kind of entity and election decision.

What Is An LLC, And How Does The IRS Tax It By Default?

A limited liability company protects your personal assets from business debts and lawsuits. That protection is a legal matter, separate from taxes.

By default, the IRS treats a single-member LLC as a disregarded entity. You report income and expenses on Schedule C of your personal return. Multi-member LLCs file as partnerships. Either way, every dollar of net profit is subject to self employment tax, which covers Social Security and Medicare.

For 2026, self employment tax is 15.3%: 12.4% for Social Security, on the first $184,500 of net earnings according to the Social Security Administration's 2026 contribution and benefit base, and 2.9% for Medicare, which has no cap. The tax applies to 92.35% of your net profit, not the full amount, which accounts for the fact that half of self employment tax is deductible.

So if your Idaho Falls business nets $100,000 in profit as a default LLC, your self employment tax works out to roughly $14,130, on top of regular income tax.

What Does It Mean To Elect S Corp Tax Status?

An S corp is not a business entity. It is a tax classification under Subchapter S of the Internal Revenue Code. An LLC can elect S corp taxation by filing Form 2553 with the IRS. Your legal structure, registered agent, and operating agreement stay exactly the same. Only the tax treatment changes.

The election splits your income into 2 buckets: salary and distributions. You must pay yourself a reasonable salary for the work you do, and that salary is subject to payroll taxes. Distributions taken above that salary are not subject to self employment or payroll tax. That is the entire reason this election exists for small business owners.

The Real Math: What S Corp Election Actually Saves

Take a business netting $110,000 a year, a fairly typical profile for an established Idaho Falls service business or consulting practice.

As a default LLC: Self employment tax base is 92.35% of $110,000, or $101,585. At 15.3%, that comes to about $15,543 in self employment tax.

As an LLC electing S corp taxation, with a $58,000 reasonable salary: Payroll tax on the $58,000 salary runs 15.3%, or about $8,874. The remaining $52,000 taken as a distribution owes no payroll tax. Total employment tax: roughly $8,874.

That is a gross savings of about $6,669 a year. Subtract the added cost of running payroll and filing a separate corporate return, typically $2,000 to $3,000 a year for a business this size, and the net savings still lands around $3,700 to $4,700 annually. Over 5 years, that is close to $20,000 staying in the business owner's pocket instead of going to FICA.

The number that matters is not your revenue. It is net profit after expenses, and the salary has to hold up as genuinely reasonable for your role. More on that below.

Does Idaho's Flat Tax Change The Math?

Idaho taxes personal income at a flat 5.3% rate, according to the Tax Foundation's 2026 state tax data, regardless of entity structure. Both an LLC and an S corp election pass income through to your personal return, so Idaho's state income tax hit is identical either way. State income tax is not where the savings or the cost lives here. Self employment tax is a federal tax, and that is where the real difference plays out.

Where Idaho does help: forming an LLC here is inexpensive. The Idaho Secretary of State charges $100 for an online Certificate of Organization, there is no franchise tax, and the annual report is free. That keeps the baseline cost of operating as an LLC low, which matters when you are weighing whether the added S corp compliance cost is worth it at your specific profit level.

When Does The S Corp Election Actually Make Sense?

• Under $40,000 in net profit: The election rarely pays off. Payroll setup, quarterly filings, and a separate tax return typically cost more than the self employment tax you would save.
• $40,000 to $60,000: This is the judgment zone. It depends on your specific salary requirement, whether you are comfortable running payroll, and your growth trajectory.
• Above $60,000: The election usually saves real money, and the savings grow as profit grows.

These are general guidelines, not a formula. The right answer depends on what a reasonable salary looks like for your specific role and industry, which is exactly the kind of number that needs an actual accountant running your actual figures rather than a rule of thumb from an article.

What The S Corp Election Costs You

The savings are real, but so are the added obligations:

• Running payroll and issuing yourself a W-2, which usually means a payroll service
• Filing Form 1120-S for the business, separate from your personal return
• Issuing a Schedule K-1 to each shareholder
• Documenting that your salary is genuinely reasonable, since the IRS can reclassify distributions as wages, with back taxes and penalties, if it is not

Clean books matter more once you're splitting salary from distributions instead of just tracking one pass-through number. If your bookkeeping isn't already set up to separate the two clearly, our QuickBooks services can get that structured correctly before your first payroll run.

There is also a quieter cost: the Qualified Business Income deduction. Under Section 199A, up to 20% of qualified business income can be deducted, but S corp salary does not count toward that deduction, only distributions do. A higher salary means a smaller QBI deduction. In most cases the self employment tax savings still outweigh the lost deduction, but it needs to be modeled alongside the payroll tax math, not ignored.

3 Mistakes Idaho Business Owners Make With This Decision

1. Setting salary too low. Paying yourself $25,000 and taking $85,000 in distributions to dodge payroll tax is exactly the pattern the IRS looks for. "Reasonable" gets measured against what someone in your role and industry would actually earn.
2. Ignoring the compliance cost. Plenty of online calculators show the gross tax savings and stop there. The real question is net savings after payroll and filing costs, not the headline number.
3. Electing too early. Making the S corp election before your business has stable, predictable profit makes it hard to set an appropriate salary and can cost more than it saves in a slow year. Getting your bookkeeping set up correctly from the start makes that profit picture a lot easier to see clearly.

Frequently Asked Questions

Can an LLC elect S corp taxation without changing its legal structure?
Yes. Filing Form 2553 with the IRS changes how the business is taxed, not its legal status. You remain an LLC under Idaho law, with the same operating agreement and registered agent requirements.

Is an S corp always cheaper than an LLC for taxes?
No. Below roughly $40,000 in net profit, payroll and filing costs for an S corp typically outweigh the self employment tax savings. The LLC's default taxation is usually the better fit at that level.

Does Idaho's state income tax change based on my entity's tax status?
No. Idaho's flat 5.3% rate applies to pass-through income the same way whether you are a default LLC or an LLC taxed as an S corp. The difference between the two shows up in federal self employment and payroll tax, not state income tax.

What counts as a "reasonable salary" for an S corp owner?
There is no fixed IRS percentage or formula. It depends on your role, industry, experience, and what a comparable employee would earn for the same work. This is one of the areas where working with a CPA who knows your specific business matters most.

When is the deadline to elect S corp status for the current tax year?
Generally March 15 for calendar-year businesses, though late election relief is available in some circumstances. Missing the deadline usually means waiting until the following tax year.

Do I need payroll if my LLC elects S corp taxation?
Yes, without exception. Shareholder-employees must receive W-2 wages through a proper payroll system. There is no workaround for this requirement.

How To Catch Up On Late Business Taxes Without Losing Your Mind

If your business is behind on business taxes, the fastest way to limit the damage is to stop avoiding the problem and file the missing returns first, even if you cannot pay the full amount yet. The IRS charges separate penalties for filing late and paying late, so filing quickly is what actually saves you money. From there, payment plans, penalty relief, and professional help can get your business fully caught up without losing everything you have built.

Why Idaho Falls Business Owners Fall Behind On Business Taxes

Falling behind on business taxes rarely happens because someone is trying to dodge the IRS. It usually happens because cash got tight one quarter and payroll tax withholdings covered payroll instead of getting sent in. It happens because quarterly estimated payments got missed during a busy season, or bookkeeping fell 3 or 4 months behind and nobody noticed until the deadline had already passed. None of that makes the problem less serious, but it does mean you are not the first Idaho Falls business owner to be in this spot, and it is fixable.

Step 1: Open The Mail And Stop Avoiding The IRS

The IRS does not shut down a business the moment a return is late. Before any serious collection action, the agency typically sends several written notices over a period of months, each one giving you a chance to respond. Ignoring those notices is the single most common way a manageable problem turns into a serious one. If you have unopened IRS mail sitting in a drawer right now, that is the first thing to deal with, not the payment amount.

Step 2: Gather What You Need To File

Before you or your accountant can file a late return, you need the paperwork behind it. Pull together:

• Prior year business bank and credit card statements
• Payroll records and any W-2s or 1099s issued
• QuickBooks or bookkeeping records for the periods in question
• Copies of any prior filed returns
• Your EIN and any IRS notices already received

If records are missing or your bookkeeping fell behind, an IRS wage and income transcript can help reconstruct what was already reported to the agency, which is often the fastest way to rebuild an accurate picture.

Step 3: File The Late Returns First, Even If You Cannot Pay In Full

A lot of business owners assume there is no point filing a return until they can pay the full balance. That is not accurate, and it is the mistake that costs the most money. The failure-to-file penalty runs about 5 percent of the unpaid tax for each month a return is late, up to a 25 percent cap. The failure-to-pay penalty is a separate, much smaller 0.5 percent per month. Filing the return as close to on time as you can manage, and paying later, is almost always cheaper than waiting to file until you have the money.

Step 4: Deal With What You Actually Owe

Once the returns are filed, you have real options for the balance itself.

According to the IRS, businesses that owe less than $25,000 in combined tax, penalties, and interest from the current and prior tax year can apply online for a long-term payment plan and make monthly payments for up to 24 months. Balances between $10,000 and $25,000 are required to use direct debit. If your business owes more than $25,000, you will need to work directly with the IRS, or with a CPA who can negotiate on your behalf, to set up a different type of arrangement.

If this is the first time your business has fallen behind, ask about first-time penalty abatement. The IRS will often waive failure-to-file and failure-to-pay penalties for a first-time offense if your filing history is otherwise clean.

For businesses that genuinely cannot pay the full balance even with more time, an offer in compromise allows you to settle the debt for less than what you owe, based on your income, assets, and ability to pay. These are not quick or easy to get approved, which is exactly where a CPA who has done this before earns their fee.

Common Mistakes That Make A Bad Tax Situation Worse

• Waiting to file until you can pay in full, which lets the larger failure-to-file penalty keep growing
• Ignoring IRS notices instead of opening and responding to them
• Trying to negotiate a payment plan without knowing what your business actually qualifies for
• Focusing only on old debt while falling further behind on the current year's taxes

You do not have to sort this out alone, and you do not need all the answers before you call.

Frequently Asked Questions

What happens if my business does not file taxes on time?

If your business misses a filing deadline, the IRS applies a failure-to-file penalty of about 5 percent of the unpaid tax for every month the return is late, up to a maximum of 25 percent. A separate failure-to-pay penalty of 0.5 percent per month also applies to any unpaid balance, and interest accrues on top of both. Filing the return as soon as possible, even without payment, stops the larger of the 2 penalties from continuing to grow.

Can the IRS shut down my business for unpaid taxes?

In serious, long-ignored cases, yes. The IRS can file a lien against business assets or levy a business bank account, which can make it impossible to make payroll or pay vendors. In practice, this happens after a business has ignored multiple written notices over months, not as an immediate first step, which is why responding early matters.

Will I go to jail for owing business taxes?

No, simply owing back taxes or falling behind on filing is not a criminal matter, and most businesses that work with the IRS resolve it through payment plans or settlements. Jail time is reserved for willful tax evasion or fraud, such as deliberately hiding income, not for honest cash flow problems or missed deadlines.

How do I set up an IRS payment plan for my business?

Businesses that owe less than $25,000 in combined tax, penalties, and interest from the current and prior tax year can apply for a long-term payment plan online through the IRS Online Payment Agreement tool, with up to 24 months to pay. Balances between $10,000 and $25,000 require automatic direct debit payments. Businesses owing more than $25,000 need to contact the IRS directly or work with a CPA to arrange a different type of agreement.

What is an IRS offer in compromise?

An offer in compromise is an agreement that lets a business settle its tax debt for less than the full amount owed, based on the IRS's assessment of income, assets, and ability to pay. It is intended for businesses that genuinely cannot pay their full balance even with a payment plan, and applications are frequently denied when they are not carefully prepared, which is why most businesses pursue this option with a CPA's help.

Should I hire a CPA if I am behind on business taxes?

Yes, especially once more than one tax period is involved or the IRS has already sent a notice. A CPA can help you file accurately, figure out which payment option your business actually qualifies for, and, in serious cases, communicate with the IRS directly so you are not doing it alone. The earlier you bring someone in, the more options are usually still on the table.

How to Know If Your QuickBooks Books Are Actually Accurate (And What to Do If They're Not)

If your QuickBooks reports look fine but something still feels off, trust that feeling. Accurate books mean every transaction is recorded, categorized correctly, and reconciled against your actual bank and credit card statements, not just entered and left alone. You can check this yourself in about 10 minutes using 4 reports inside QuickBooks. If the numbers don't hold up, the fix depends on how far behind things are, and in some cases it's a quick correction rather than a full cleanup project.

Why "It Looks Fine" Doesn't Mean It's Accurate

A lot of business owners assume that if QuickBooks isn't throwing errors and the Profit and Loss report generates without a hitch, the books are accurate. That's not true.

QuickBooks will happily generate a clean-looking report from bad data. It doesn't know that a $4,000 deposit was recorded twice, that a loan payment got logged entirely as an expense instead of split between principal and interest, or that 3 months of transactions are sitting in "Uncategorized Expense" waiting to be sorted. The software isn't checking your work. It's just doing math on whatever you gave it.

That's the gap between "the report ran" and "the report is right."

The 10-Minute Accuracy Check You Can Run Right Now

Before you assume anything, pull up these 4 reports and look for the specific red flags below.

1. Reconciliation status. Go to Settings and check whether your bank and credit card accounts are marked as reconciled through last month. If reconciliation hasn't happened in 60 days or more, nothing downstream can be trusted, because reconciliation is the step that confirms QuickBooks matches your actual bank statement.

2. Balance sheet. Pull up your balance sheet and look at 3 accounts specifically: Undeposited Funds, Accounts Receivable, and any loan balance. If Undeposited Funds has a growing balance instead of clearing out regularly, deposits aren't being matched to the invoices or sales that created them. If a loan balance on the sheet doesn't match your most recent loan statement, principal and interest are probably being recorded incorrectly.

3. Accounts Receivable and Accounts Payable aging reports. Run both. If you see invoices marked unpaid that customers actually paid months ago, or vendor bills sitting open that you know are settled, your aging reports are inflating what you're owed and what you owe.

4. Uncategorized Income and Uncategorized Expense. Search your Chart of Accounts for these 2 categories. Any balance here means transactions were recorded but never assigned to a real account. Even $500 sitting in Uncategorized Expense means your P&L is incomplete for that period.

If all 4 come back clean, your books are in good shape. If even one doesn't, keep reading.

The Signs Your Books Have a Real Problem

Beyond the 10-minute check, watch for these patterns over time:

• Your bank balance and QuickBooks balance are frequently different by more than a small timing gap
• The same vendor or customer shows up twice with slightly different spellings
• Negative balances appear in accounts that should never go negative, like inventory or a bank account
• Your bookkeeper, or you, only trust the P&L after manually adjusting it each month
• Payroll or sales tax entries don't match what was actually filed and paid
• You've gone more than one full quarter without a completed bank reconciliation

Any one of these on its own might be a quick fix. Several at once usually means the books have drifted further than a single afternoon can correct.

What Happens If You Ignore It

Here's the part most guides skip: balance sheet errors don't stay contained. They carry forward. A miscoded deposit from March is still sitting in the wrong account in November, and every report you pull in between is built on top of that error.

That matters most at 2 points. First, when you're making a real business decision, like whether you can afford to hire, based on a cash position that isn't real. Second, and more urgent for a CPA firm to flag: when it's time to file. A tax return prepared from books with miscoded income, missing expenses, or an inaccurate sales tax payable account will contain errors that follow you into the filing itself. Accurate books aren't just good practice, they're what the IRS expects small businesses to maintain in the first place. Cleaning up the books after the return is filed is a much harder conversation than cleaning them up before.

DIY Cleanup vs. When to Call a CPA

Not every messy file needs a professional. Here's a straightforward way to sort it:

Handle it yourself if:

• You're behind less than 60 days
• The issue is limited to categorization, not reconciliation
• You have access to all your bank and credit card statements for the period in question
• No payroll, sales tax, or loan accounts are involved

If you handle it yourself, PDK also offers QuickBooks setup and QuickBooks training for Idaho Falls business owners who want a professional to double-check the file structure without a full cleanup engagement.

Call a CPA if:

• Reconciliation has been skipped for more than a quarter
• Balance sheet accounts (loans, equity, Undeposited Funds) look wrong and you're not sure why
• Payroll or sales tax entries don't match filings
• You're approaching a tax deadline and don't trust the numbers feeding into it
• Multiple people have had access to the file and changes can't be traced

The second list is exactly where a project-based cleanup, done once, done right, and reconciled against real statements, saves more time than it costs.

What Cleanup Looks Like at Poston Denney & Killpack

Most QuickBooks cleanup services stop at handing back a reconciled file. Poston Denney & Killpack has been an Idaho Falls CPA firm since 1984, and the same team that cleans up your books is the team that will use them to prepare your tax return, so the cleanup is done with that end result in mind, not just a tidy-looking report.

Bruce Denney, CPA and CVA, has over 20 years of public accounting and tax experience, and Kevin Killpack brings accounting and management consulting experience across small and large businesses. That means a cleanup isn't handed off to someone unfamiliar with what the IRS and Idaho state filings actually require from your chart of accounts. It's reviewed by the same CPAs who sign your return.

PDK is also BBB accredited with an A+ rating, and the firm has built its reputation in Idaho Falls on personalized service rather than passing clients off to whoever's available. If you'd rather talk to the same person each time instead of a rotating support queue, that's the model here.

Frequently Asked Questions

How do I know if my QuickBooks needs a cleanup or just a quick fix?
Run the 10-minute check above. If only categorization is off and you're less than 60 days behind, a quick fix usually covers it. If reconciliation has lapsed for a quarter or more, or balance sheet accounts don't match real statements, that's a cleanup project, not a quick fix.

Will a QuickBooks cleanup affect my past tax returns?
No, as long as the periods covered by already-filed returns stay locked and untouched during cleanup. A CPA doing the work should confirm this with you before making any changes to closed periods.

How long does a QuickBooks cleanup take?
Most cleanup projects take 1 to 3 weeks, depending on how many months are unreconciled and how many accounts are involved. A file that's 2 months behind takes far less time than one that's 2 years behind.

Can I clean up QuickBooks myself?
Yes, for smaller issues like uncategorized transactions or a few months of missed reconciliation. Once payroll, sales tax, or loan accounts are involved, or you're unsure why a balance is wrong, professional review prevents a second round of corrections later.

What's the difference between QuickBooks cleanup and monthly bookkeeping?
Cleanup is a one-time project to bring historical books to an accurate, reconciled baseline. Monthly bookkeeping is the ongoing work that keeps books accurate going forward so cleanup doesn't become necessary again.

Does a messy QuickBooks file actually affect my taxes?
Yes. If income is miscoded, expenses are missing or duplicated, or sales tax payable doesn't reflect what was actually collected, those same numbers flow directly into the return prepared from them.
