Form 843 (2026): How to Request IRS Penalty Abatement

Form 843, Claim for Refund and Request for Abatement, is the IRS form for asking that penalties, certain fees, and interest caused by IRS error be removed from your account. For the most common relief — first-time abatement of failure-to-file and failure-to-pay penalties — you often don't need the form at all: a phone call to the number on your IRS notice can erase the penalty on the spot. With late-filing penalties running 5% per month up to 25% of the tax due, a granted request is routinely worth four figures.

Key takeaways:

• The failure-to-file penalty is 5% per month, capped at 25%, with a minimum of $525 for returns due in 2026 that are over 60 days late; failure-to-pay adds 0.5% per month
• First-time abatement (FTA) requires three things: no penalties in the prior 3 years, all required returns filed, and tax paid or a payment plan in place
• Fastest route for FTA: call the number on your notice; Form 843 or a written statement works for everything else
• Form 843 does not cover the estimated-tax penalty or income-tax refund claims
• When a penalty is removed, the interest charged on that penalty comes off automatically
• Denied? You have 30 days from the denial letter (Letter 854C) to request an appeal

What Form 843 Does

Form 843 is the IRS's general-purpose request form for refunding or abating charges that aren't ordinary income tax: penalties, additions to tax, certain excise and employment taxes, fees, and interest that the IRS itself caused through error or delay. The current revision is December 2024, and the Instructions for Form 843 require a separate form for each type of tax or fee and for each tax period. Three years of late-filing penalties means three Forms 843.

A deadline sits underneath every request: a claim for credit or refund must generally be filed within 3 years from the date you filed the return or 2 years from the date you paid the tax, whichever is later. Penalties you paid four years ago are usually gone for good.

The Penalties You're Asking the IRS to Remove

Penalty abatement is worth real money because the underlying rates are steep. Three numbers, all from IRS penalty pages current as of July 2026:

When both penalties run in the same month, the failure-to-file penalty is reduced to 4.5% so the combined hit is 5% per month. Take Odette, a freelance photographer who filed her 2024 return four months late with $8,000 unpaid. Her failure-to-file penalty is 4.5% × 4 months × $8,000 = $1,440; failure-to-pay adds 0.5% × 4 × $8,000 = $160, and it keeps accruing until she pays. That is $1,600 of penalty before interest, and every dollar of it is eligible for first-time abatement if her record is clean. Our late filing penalty guide breaks down the penalty mechanics in more depth.

First-Time Abatement: The 3-Part Eligibility Checklist

First-time abatement is an administrative waiver, not a mercy plea: if you meet the criteria, the IRS grants it without asking why you were late. Per the IRS First Time Abate policy, it covers failure-to-file, failure-to-pay, and failure-to-deposit penalties. You qualify when all three are true:

1. Clean 3-year history. No penalties on the same return type for the prior three years. Two details people miss: an estimated-tax penalty in those years does not break your record, and neither does a penalty that was assessed but later abated for reasonable cause or IRS error.
2. Filing compliance. All currently required returns are filed (or on a valid extension). The IRS will not abate a penalty for a taxpayer with another return still missing.
3. Payment compliance. The tax is paid, or you have an arrangement in place; an approved installment agreement with current payments counts.

One strategic note from practice: FTA is a card you hold roughly once every four years. If you have genuinely strong reasonable cause for the year in question, some practitioners argue the cause first and preserve FTA for a year when no excuse exists. Nothing in IRS policy requires that sequencing; it is simply worth knowing the card exists before you play it.

Reasonable Cause: What Counts and What Doesn't

Reasonable cause is the relief path for taxpayers who don't qualify for FTA. The test, per the IRS reasonable cause standards, is whether you exercised ordinary business care and prudence but couldn't comply anyway.

A persuasive reasonable-cause request establishes four facts: what happened, when it happened, how it prevented you from filing or paying, and what you did to comply as soon as circumstances changed. Attach evidence: hospital records with dates, insurance or FEMA documentation, a death certificate, dated correspondence. Vague hardship narratives without documents are the requests that come back denied.

Phone Call, Form 843, or Written Statement: Which to Use

The IRS accepts abatement requests through three channels, and matching the channel to your situation saves weeks.

A representative can make the phone call or sign the request for you, but only with a power of attorney on file; our Form 2848 vs Form 8821 guide explains which authorization that requires.

What Form 843 Does NOT Cover

The instructions open with a list of forbidden uses, and the estimated-tax penalty tops it in practice:

• ❌ The estimated-tax penalty (Form 2210). Underpayment-of-estimated-tax penalties are generally not abatable through Form 843 or FTA; waivers are requested on Form 2210 itself, on narrow grounds like casualty or retirement after age 62
• ❌ Income tax refunds. Overpaid income tax is claimed on Form 1040-X, never Form 843
• ❌ Employment tax corrections. Employers amend with 941-X, 943-X, or 944-X
• ❌ Additional Medicare Tax refunds and FICA claims that belong on amended employment returns
• ❌ User fees for installment agreements or offers in compromise, and lien fees

If your penalty is the estimated-tax kind, size the exposure first with our estimated tax penalty calculator; the fix there is usually adjusting safe-harbor payments, not an abatement letter.

How to Fill Out Form 843

The form itself is one page. The load-bearing entries:

• Lines 1–3: the tax period, the amount to be refunded or abated, and the type of tax or fee
• Line 4: the penalty's IRC section if you're disputing a specific penalty (for late filing, §6651)
• Line 7 checkbox: pick the legal basis. Box a = interest caused by IRS errors or delays (IRC §6404(e)); box b = penalty caused by erroneous written IRS advice; box c = reasonable cause; box d = other, which is where an FTA request in writing lands
• Explanation: the facts, dated, with documents attached
• Signature: yours, or your representative's with a Form 2848 attached

Where to file depends on context. Responding to a notice? Use the address on the notice. No notice? Send it to the service center where your current-year return goes. Niche cases (estate and gift matters, branded prescription drug fees) have dedicated addresses listed in the instructions.

Sample Request Language

Short and factual beats long and emotional. For a first-time abatement request in writing:

"I request abatement of the failure-to-file and failure-to-pay penalties assessed for tax year 2024 under the First Time Abate administrative waiver. All required returns for the prior three years were filed timely with no penalties assessed, all currently required returns are filed, and the balance is paid in full."

For reasonable cause:

"I request abatement of the failure-to-file penalty for tax year 2024 for reasonable cause. I was hospitalized from March 28 to May 9, 2025, during the filing period (records attached), and filed on June 2, 2025, within weeks of discharge."

Two or three sentences of verifiable fact, evidence attached, no apology paragraph.

How Long Penalty Abatement Takes

The IRS publishes no service standard for abatement decisions, so plan around the channel. A phone FTA request can be approved during the call, with a confirmation letter arriving by mail afterward. Written requests, whether Form 843 or a statement, are answered by letter, and in our experience helping business owners through the process, several weeks to a few months is the realistic window, longer during filing season. The clock matters because failure-to-pay penalties and daily-compounding interest keep accruing on any unpaid balance while you wait; abatement is not a pause button.

If the IRS Denies Your Request: The 30-Day Appeal

A denial arrives as Letter 854C, which explains the reason and your appeal rights. Per the IRS penalty appeal process, you generally have 30 days from the date of the denial letter to request an appeal with the IRS Independent Office of Appeals. The request is a written protest: your name and contact details, the tax periods and penalties involved, a statement that you want to appeal, and the facts and law supporting your position: essentially a sharper version of your original request, aimed at a fresh reviewer. Appeals officers weigh hazards of litigation, which means a documented, borderline reasonable-cause case often does better there than at the service center.

Does Abatement Remove Interest Too?

Interest tied to an abated penalty disappears with it: the IRS automatically reduces or removes interest charged on a penalty when that penalty is reduced or removed. Interest on the underlying tax is a different animal. IRC §6404 allows abatement only where the interest resulted from an unreasonable error or delay by the IRS in performing a managerial or ministerial act (a lost file, a misrouted case), and you contributed nothing significant to the delay. "The interest feels unfair" is not a ground; if you owe the tax, the 7% keeps running until it's paid.

Common Mistakes With Form 843

Requesting FTA by mail when a call would do. A written FTA request waits in a paper queue; the same request on the phone can be resolved that afternoon.

One form for three years of penalties. The instructions require a separate Form 843 per period and per tax type. Bundled requests bounce.

Aiming Form 843 at an estimated-tax penalty. That penalty lives on Form 2210 and has its own narrow waiver rules; an 843 request for it is a dead letter.

Ignoring the missing-return problem. FTA requires all currently required returns to be on file. Requesting abatement while a later-year return is delinquent gets denied on compliance grounds.

Letting the refund clock lapse. Paid the penalty more than two years ago (and filed more than three years ago)? The refund claim is time-barred no matter how strong the cause.

Treating a denial as final. Letter 854C starts a 30-day appeal window that most taxpayers never use, and Appeals reverses service-center denials regularly enough to be worth the stamp.

Action Checklist

• Pull your IRS account transcript and list each penalty, year, and amount
• Check the FTA test: prior 3 years penalty-free, all returns filed, balance paid or on a plan
• FTA-eligible with a notice? Call the toll-free number in the top corner of the notice and ask for First Time Abate
• Otherwise, complete one Form 843 per penalty per year, check the right box on line 7, and attach dated evidence
• Mail to the address on your notice, or to your filing service center if no notice exists
• Calendar the response; penalties and 7% daily-compounding interest accrue on unpaid balances while you wait
• If Letter 854C arrives, file a written appeal protest within 30 days
