IRS Penalty Abatement Guide for Tax Preparers: FTA, Reasonable Cause, and Form 843

Penalty abatement is one of the most actionable services a tax preparer can offer clients who receive an IRS penalty notice. When a client opens a CP2000, CP14, or similar IRS notice and sees hundreds or thousands of dollars in failure-to-file or failure-to-pay penalties stacked on top of the underlying balance, the natural instinct is to pay and move on. A preparer who knows the abatement process can often get those penalties removed, at no cost to the client beyond the preparer's time, and at a meaningful fee to the practice.

This guide covers the complete IRS penalty abatement workflow for PTIN holders, AFSP participants, and enrolled agents: which penalty types qualify, first-time abatement (FTA) eligibility and the 2026 automatic FTA program, how to request abatement over the phone via the Practitioner Priority Service, the written request format, Form 843 for paid-penalty refund claims, reasonable cause documentation, how FTA and reasonable cause interact, and the procedural errors that get requests denied before the IRS ever considers the merits.

All figures, program details, and statutory references in this guide should be verified at IRS.gov before relying on them in client engagements. IRS administrative programs and processing procedures are subject to change. This guide is informational and does not constitute legal or tax advice.

What Penalty Abatement Is and Why It Belongs in Your Client Services

Penalty abatement is the process of asking the IRS to reduce or remove a penalty that has been assessed against a taxpayer's account. The IRS assesses penalties automatically when returns are filed late, taxes are paid late, or required deposits are missed. These assessments happen by computer. The system applies the penalty according to the statute and moves on. It does not know whether the taxpayer has an otherwise spotless ten-year compliance history, whether a family medical crisis caused the filing delay, or whether the client relied on incorrect IRS advice when making a payment. The abatement process is how those facts get in front of a human being who can remove a charge the computer had no reason not to impose.

For preparers, the practical value is twofold. First, clients with penalty notices are motivated buyers of professional help; they have a specific problem with a dollar figure attached, and they want it solved. Second, the abatement process is learnable and largely procedural. A preparer who works one or two cases develops a repeatable workflow: pull the transcript, check FTA eligibility, call PPS or draft the letter, document the outcome. That workflow scales. Preparers who build a penalty abatement service into their practice add a consistent revenue stream that runs year-round, not just during filing season.

One important boundary: penalty abatement is not a guarantee. The IRS may approve a request based on the individual client's compliance history and the specific facts presented, or it may decline. Approval depends on criteria the IRS verifies at the time of the request. A preparer should never represent abatement as certain; the correct framing is that the client appears to qualify and the IRS may approve the request based on those facts.

Penalty Types That Qualify for Abatement and What Is Excluded

Not every penalty the IRS imposes is eligible for abatement through the standard administrative routes. Understanding which penalty code sections are in play before you start a request is not optional: requesting abatement of an ineligible penalty wastes the client's time, clutters the IRS account, and can create confusion about the remaining balance. Here are the three penalty types that qualify for first-time abatement and reasonable cause abatement, followed by the categories that do not.

Penalties that qualify for abatement

Penalties explicitly excluded from standard abatement

• Accuracy-related penalties (IRC Section 6662): These include the substantial understatement penalty, the negligence or disregard of rules penalty, and the substantial valuation misstatement penalty. They arise from examination adjustments, not from late filing or payment, and are not eligible for first-time abatement. Reasonable cause defenses to Section 6662 penalties require a much higher evidentiary bar and are typically litigated at the exam or appeals level rather than through an administrative abatement request.
• Civil fraud penalty (IRC Section 6663): The civil fraud penalty (75 percent of the underpayment attributable to fraud) is not eligible for administrative abatement. Cases involving Section 6663 assessments require qualified legal representation and are outside the scope of standard preparer penalty work.
• FBAR penalties: FBAR penalties are assessed under Title 31 of the United States Code (the Bank Secrecy Act), not under the Internal Revenue Code. They are administered by a separate function within the IRS and are not subject to the same administrative abatement procedures that apply to IRC penalties. FBAR penalty disputes require separate legal procedures. Refer clients with FBAR penalty issues to a qualified tax attorney or EA specializing in international compliance.
• Estimated tax penalties (IRC Section 6654): The estimated tax penalty for underpayment of individual estimated tax is a statutory interest charge, not a discretionary penalty. The IRS does not routinely abate it through administrative requests, though limited statutory exceptions apply (such as the prior-year safe harbor, casualty or disaster, and unusual circumstances). Preparers handling estimated tax penalty situations should review the specific exceptions enumerated in Section 6654 rather than treating it as a standard abatement case. Verify current Section 6654 exceptions at IRS.gov.

First-Time Abatement: Eligibility Criteria and How to Confirm Qualification

First-time abatement is an IRS administrative waiver that allows the removal of failure-to-file, failure-to-pay, and failure-to-deposit penalties for a taxpayer who has demonstrated a clean compliance history. It does not require a specific reason for the noncompliance. A client who simply forgot to file or ran short on cash can qualify for FTA as long as their prior-year record meets the criteria. That makes FTA the first tool to reach for in any penalty abatement engagement: check FTA eligibility before you spend time developing a reasonable cause argument.

The three FTA eligibility requirements

The IRS applies three criteria when evaluating an FTA request. All three must be satisfied for the tax year (or period) at issue. Verify current FTA criteria at IRS.gov before advising clients, as the IRS may update administrative guidance on how these criteria are applied.

Before making any FTA request, pull the client's IRS account transcript using IRS e-Services and your authorized CAF number. Confirm that prior years show filed returns, no penalty assessments, and a zero or IA-covered balance. A request based on inaccurate assumptions about the transcript is the fastest way to a denial and a confused client.

2026 Automatic FTA: What Changed and What Preparers Must Still Monitor

Per current IRS guidance, the IRS is automatically applying first-time abatement to eligible failure-to-file and failure-to-pay penalties assessed on tax year 2025 returns filed in 2026. This represents a procedural shift: rather than requiring taxpayers or their representatives to request FTA after receiving a penalty notice, the IRS is running the eligibility check on its end and removing qualifying penalties without a formal request. The practical effect is that clients who would have received a penalty notice and needed help removing it may instead see the penalty disappear from their account without preparer intervention. Verify with IRS.gov as program details may change.

This automatic application does not eliminate the preparer's role. It narrows it to specific situations that still require action. First, automatic FTA applies only to tax year 2025 (the year for which returns were due in 2026). It does not apply retroactively to tax year 2024, 2023, or any earlier year. Clients with pending penalty notices or open balances for prior years still need a manual request. Second, the IRS's automated eligibility determination is only as good as the data in its systems. If a client has an unresolved transcript issue (a return showing as unfiled that was actually filed, a payment not credited correctly, or a prior penalty that should not have been assessed), the automatic process may deny a client who should qualify. Preparers who monitor client transcripts proactively will catch these situations; those who assume the automatic process handled everything may miss them.

Third, the automatic FTA program does not cover failure-to-deposit penalties for employment tax accounts or all other penalty categories, so payroll clients and clients with specialized penalty types are outside the automatic coverage. Review each client's specific penalty notice and transcript against the current scope of the automatic program before concluding no action is needed.

Prior-Year FTA Requests via Practitioner Priority Service: The Fastest Route

For tax year 2024 and earlier, the fastest way to request first-time abatement is a phone call to the IRS Practitioner Priority Service (PPS). PPS is the dedicated IRS phone line for tax professionals. Calling PPS with a valid Form 2848 CAF number on file is faster than a written request in most cases; IRS representatives can pull the transcript on the call, verify eligibility, and input the abatement in real time. A confirmed abatement on the phone typically reflects on the account within a few business days. See the Practitioner Priority Service guide for the PPS phone number, hours, and authentication procedures.

What you need before the call

• A valid Form 2848 on file for the client, with your CAF number, covering the tax years and penalty types at issue. The IRS representative will verify this at the start of the call. Without it, the representative cannot discuss the account with you. See the Form 2848 and CAF number guide for how to establish representation authority and register with the Centralized Authorization File.
• The client's Social Security Number or EIN, the specific tax periods at issue, and the penalty notice number (typically found on the CP notice the client received).
• The IRS transcript for the account, which you should have already pulled via e-Services to confirm FTA eligibility before the call. Walking into a PPS call without knowing the transcript means you may request abatement the IRS will immediately deny and have no fallback position.

What to say and what the IRS checks

Once authenticated, state clearly: "I am calling to request first-time abatement of the [failure-to-file / failure-to-pay / failure-to-deposit] penalty assessed for tax year [year] under IRC Section [6651(a)(1) / 6651(a)(2) / 6656]. My client has a clean three-year filing and payment history for the prior three years and meets the FTA eligibility criteria." The representative will pull up the account and verify the three criteria on their end: prior-year filing compliance, absence of penalties for the prior three years, and the current payment status of the underlying tax. If all three check out, the representative will input the abatement and give you a confirmation number. Record the confirmation number, the representative's employee ID, the date and time of the call, and the penalty amounts approved for removal. That documentation belongs in the client's file.

If the representative declines the request on the phone, ask for the specific reason. Common denial reasons include an unfiled prior-year return showing in the system, a prior penalty the preparer was not aware of, or a balance still outstanding without an IA. Each of those is fixable; understanding the exact issue on the call lets you address it before calling back or sending a written request.

Written FTA Request: Format and Required Elements

When a PPS call is not practical, or when the IRS representative declines and the preparer wants to establish a written record for potential appeals, a letter request is the alternative. A written FTA request goes to the IRS address on the penalty notice or, if responding to an existing case, to the address of the IRS unit handling the account. Always send written correspondence by certified mail with return receipt and keep the mailing receipt and signed delivery confirmation in the client file.

What to include in a written FTA request

A complete written FTA request contains all of the following elements. Missing any of them risks a return-without-action or a denial that does not address the actual merits.

• Taxpayer identification: Full legal name, Social Security Number or EIN, and current address. If you are writing on behalf of the client as their authorized representative, include your name, firm name, and CAF number, and attach a copy of Form 2848.
• Tax periods and penalty amounts: Identify each specific tax period at issue (for example, "Form 1040, tax year ending December 31, 2024") and the dollar amount of the penalty being contested as shown on the IRS notice. Reference the notice number if one was issued.
• IRC section cited: State the specific penalty type by its IRC section (for example, "failure-to-file penalty under IRC Section 6651(a)(1)"). This ensures the IRS routes the letter to the correct function and processes it against the correct abatement criteria.
• FTA eligibility assertion: Explicitly state that the taxpayer qualifies for first-time abatement. Include the assertion that: (1) all required returns for the three prior years were timely filed or extensions obtained, (2) no failure-to-file, failure-to-pay, or failure-to-deposit penalties were assessed for those three years, and (3) the underlying tax for the period at issue is paid in full or the taxpayer is in a current installment agreement (state which applies).
• Supporting documentation: Attach copies of filed returns or extension confirmations for the three prior years if the IRS may have transcript gaps. For installment agreement cases, attach a copy of the IA confirmation. Include the client's signature authorizing the request if not proceeding entirely through Form 2848.
• Requested relief: State the outcome requested: removal of the penalty in full, or in the alternative, abatement to the extent the IRS determines appropriate. Specifying the exact dollar amount requested and the penalty period makes the IRS's work easier and reduces the risk of a partial response that requires follow-up.

Form 843 Line-by-Line: Claiming a Refund of a Paid Penalty

A phone call to PPS or a written abatement letter addresses penalties that have been assessed but not yet paid. When a client has already paid a penalty, the mechanism for recovery is Form 843, Claim for Refund and Request for Abatement. Form 843 is not the same as a tax return refund claim; it is a formal request for the IRS to return penalty (or interest) amounts that were paid and should not have been charged. The statute of limitations is tighter and the documentation requirements are higher, so the form deserves specific attention in any abatement practice.

When to use Form 843 instead of calling

Use Form 843 when the penalty has already been paid and the client wants the money back. A PPS phone call can remove an assessed-but-unpaid penalty from the account; it cannot generate a refund check for an amount the client already sent to the IRS. Form 843 is also appropriate when requesting abatement of interest (under IRC Section 6404 for interest attributable to IRS error or delay) or when the request is complex enough that a formal written record is preferable to a phone call, even if the penalty is not yet paid.

Statute of limitations under IRC Section 6511

This is the most common procedural error in paid-penalty refund cases. Under IRC Section 6511, a claim for refund of a penalty must be filed within the later of: two years from the date the penalty was paid, or three years from the date the return was filed. For most penalty refund claims, the two-year rule from payment is the operative deadline. If a client paid a penalty two years and one day ago, the refund claim is barred. No equitable exceptions exist; the statute is hard. Build a practice of asking the payment date for any paid-penalty situation before committing to a refund strategy, and verify current Section 6511 rules at IRS.gov before advising clients.

Reasonable Cause Abatement: Qualifying Circumstances and Required Documentation

Reasonable cause is the IRS's standard for abating penalties when the taxpayer had a legitimate reason for the noncompliance that was outside their control and they exercised ordinary business care and prudence in trying to meet their tax obligations. Unlike FTA, reasonable cause requires establishing specific facts. The IRS evaluates these requests on their merits; a compelling, well-documented case may succeed where a bare assertion of hardship will not. Check FTA first because it requires no factual showing, but when FTA is not available (the client has a prior penalty on record, for example), reasonable cause is the next route.

Qualifying circumstances

• Serious illness or incapacitation: A medical condition that prevented the taxpayer from filing or paying on time, where the illness was serious enough that the taxpayer could not reasonably have attended to tax obligations. Documentation should include medical records or a physician's statement confirming the condition, its severity, and the period during which the taxpayer was incapacitated. The IRS distinguishes between a chronic condition that could have been managed around and an acute condition that genuinely prevented compliance.
• Death in the immediate family: The death of a spouse, child, parent, or other person in the taxpayer's immediate household during the period just before the filing or payment deadline. Documentation should include the death certificate and, where relevant, documentation of the taxpayer's role as executor or primary caregiver for surviving dependents. The timing matters; a death that occurred six months before the deadline carries less weight than one that occurred in the week before it.
• Natural disaster or casualty: A fire, flood, earthquake, hurricane, or other disaster that destroyed the taxpayer's records or made it impossible to file or pay on time. Documentation should include insurance claims, police or fire reports, FEMA registration, or news reporting on a declared disaster for the area. If the taxpayer's records were destroyed, the IRS should be told explicitly, as missing records are a concrete consequence that supports the claim.
• Reliance on a tax professional's advice: The taxpayer relied in good faith on written advice from a competent tax advisor who incorrectly advised them on a filing or payment obligation, and that reliance was reasonable given the advisor's qualifications and the taxpayer's circumstances. For this to succeed, the reliance must have been genuine, the advisor must have been given accurate information, and the taxpayer must have actually followed the advice and not simply ignored the obligation. The IRS scrutinizes these claims closely; they require documentation of the advice given and evidence that the taxpayer acted on it.
• Erroneous IRS advice: The taxpayer received incorrect written advice from the IRS itself (for example, through a response to a written inquiry) and followed that advice in good faith. This is one of the stronger reasonable cause claims, but it requires documentation: the IRS written response must be produced and the taxpayer must show they followed it accurately.

Documentation required for a reasonable cause request

Every reasonable cause request should include: (1) a narrative explaining the specific event or circumstance, when it occurred, how it directly prevented the taxpayer from filing or paying on time, and what steps the taxpayer took to comply as soon as the circumstance was resolved; (2) supporting documentation specific to the claimed circumstance (medical records, death certificates, disaster documentation, advisor letters); and (3) a statement that the taxpayer exercised ordinary business care and prudence and complied as soon as reasonably possible after the circumstances resolved. Vague claims of general hardship or financial difficulty without a specific incapacitating event do not meet the reasonable cause standard. Financial difficulty alone, without an extraordinary event causing it, is rarely a qualifying circumstance for abatement of the failure-to-file penalty.

Stacking FTA and Reasonable Cause: IRS Priority Order and What Happens When Both Apply

A taxpayer can qualify for both first-time abatement and reasonable cause on the same penalty. When both apply, the IRS applies FTA first. This is not an arbitrary ordering; it reflects IRS procedure. The practical consequence for preparers is that if FTA removes the full penalty, the reasonable cause analysis becomes moot. However, the order matters in one important scenario: if the client has penalties for multiple years and FTA is available only for one of them, reasonable cause may be the available route for the others.

FTA is a one-time-per-penalty-type benefit per filing period. The IRS grants FTA once; it does not reset automatically each year. A taxpayer who received FTA in a prior year is not eligible to receive it again for the same penalty type until they have rebuilt a clean three-year history following the year for which FTA was granted. In practice, this means a client who was given FTA for tax year 2022 cannot use FTA again for tax year 2023 unless their 2021, 2022 (with abatement), and 2023 record is otherwise clean. If FTA is unavailable because of a prior abatement, reasonable cause is the alternative tool.

When building a multi-year abatement strategy for a client with penalties across several years, map out each year separately: which years qualify for FTA, which require a reasonable cause argument, and whether the prior abatement history affects eligibility year by year. Document that analysis in your work file. A coherent, year-by-year approach to a stacked penalty situation is also easier to present to the IRS than a single undifferentiated request covering multiple years.

Common Procedural Errors That Get Abatement Requests Denied

Substantively valid abatement requests are denied every year because of procedural mistakes that could have been caught before the request was sent. These are the errors that appear most consistently in denied cases. Reviewing this list before submitting any request is a faster quality check than re-reading the substantive criteria.

• Requesting abatement before all required returns are filed. The IRS will not consider an abatement request (whether FTA or reasonable cause) while the taxpayer has unfiled required returns. This is the most common denial that preparers should be able to prevent entirely. Pull the transcript, confirm all required years are filed, and bring any missing returns current before making the request. If the client resists filing a prior-year return, explain that the abatement is blocked until the filing obligation is met.
• Sending the request to the wrong address. The IRS has separate campuses and units for different return types and penalty notices. A penalty abatement letter sent to a generic IRS address or the address for a different type of correspondence may sit unprocessed or be returned. Use the address on the penalty notice for responses to that notice, and verify the correct submission address in the current Form 843 instructions for refund claims. Verify current mailing addresses at IRS.gov before sending.
• The base tax is still unpaid and there is no installment agreement. For failure-to-pay penalty abatement, the IRS expects the underlying tax to be paid or on an active IA. Requesting removal of the failure-to-pay penalty while the underlying balance sits open without an arrangement in place is unlikely to succeed. Resolve the payment situation first, then request the penalty abatement.
• Missing or invalid Form 2848 for PPS calls. If you attempt to call PPS and your Form 2848 is not on file with the IRS CAF unit, has expired, covers the wrong tax years, or was submitted but not yet processed, the IRS representative will not be able to discuss the account with you. Confirm CAF processing before the call. IRS e-Services allows you to verify what authorizations are on file. See the Form 2848 and CAF guide for how to verify your authorization is active before calling.
• Filing Form 843 after the statute of limitations has expired. As noted above, the Section 6511 two-year rule from the date of payment is a hard deadline. Check the payment date before drafting the Form 843, not after. A well-prepared Form 843 filed a day late is worth nothing.
• Requesting abatement of an ineligible penalty type. Requesting FTA for an accuracy-related penalty or an estimated tax penalty wastes the client's time and, in some cases, invites IRS scrutiny of the account. Know the penalty code section from the notice before drafting any request.

Building Penalty Abatement Into Your Tax Practice

A penalty abatement service is one of the more repeatable, document-driven ancillary services a tax practice can add. The work is learnable, the client need is clear (they received a notice with a dollar amount), and the outcome is either a confirmed abatement or a documented denial that preserves the client's options. Here is how to build it into a sustainable practice rather than handling each case ad hoc.

Representation requirements: Form 2848 and your CAF number

Any contact with the IRS on a client's behalf, including a PPS phone call, requires a valid Form 2848 with your Centralized Authorization File (CAF) number on file. If you do not yet have a CAF number, you obtain one by submitting your first Form 2848; the IRS assigns it and it stays with you for your entire career as a practitioner. Your representation authority under Form 2848 is limited by your credential level: PTIN-only preparers and AFSP participants have limited representation rights for returns they prepared, covering customer service matters; enrolled agents have unlimited representation rights before all IRS functions. Penalty abatement via PPS is generally treated as a customer service matter, but for complex cases or those involving collection action, an EA credential provides broader authority to act. See the Form 2848 guide for a complete breakdown of representation authority by credential type.

Fees and scope letters

Charge for penalty abatement work as a defined service, not as part of a flat annual preparation fee. The common fee structures are: a flat fee per penalty period addressed (typically ranging from a few hundred dollars for a straightforward FTA phone call to higher amounts for a written reasonable cause request with document assembly), or an hourly rate. Because the outcome of any abatement request depends on IRS determination, never charge a contingency fee tied to whether the penalty is removed. Contingency fees for services before the IRS are prohibited for enrolled agents under Circular 230 (Section 10.27), and using them regardless of credential creates a problematic incentive structure.

Every penalty abatement engagement should be covered by a written scope letter or engagement letter that specifies: the specific penalty periods and notice numbers being addressed, the basis for abatement (FTA, reasonable cause, or both), the services you will perform (transcript review, Form 2848, PPS call, written request, Form 843), the fee, and a clear statement that abatement approval depends on IRS determination and is not guaranteed. That last point protects you if the request is denied; a client who expected a certain outcome and received a denial will have fewer grounds for a dispute if the engagement letter framed the request as an application subject to IRS review, not a certain removal.

Credential paths that expand your abatement practice

PTIN-only preparers can handle straightforward FTA requests for returns they prepared, within their limited representation authority. The Annual Filing Season Program (AFSP) expands that authority to customer service matters for returns you prepared. But the enrolled agent designation gives you unlimited representation rights before every IRS function, including collection, appeals, and examination. For a preparer who wants to build a full penalty abatement and tax resolution practice, the EA is the credential that removes the ceiling. The AFSP guide covers the CE requirements and limited representation rights; the EA exam guide for 2026 covers the path to full representation authority. For clients with penalty situations that escalate into offer in compromise or other collection resolution work, the OIC preparer guide covers when to escalate and what that work requires.
