Taxpayers who missed the filing deadline and now face a penalty of 5% of unpaid tax for every month the return is late, up to a 25% maximum, have a direct path to wipe that charge: asking the IRS for first-time penalty abatement. The agency’s own procedural guidance treats this administrative waiver as a distinct relief category, separate from reasonable cause claims, and it requires no proof of a specific hardship event. For filers with a clean compliance history, the request can eliminate hundreds or thousands of dollars in penalties with a single form.
How the late-filing penalty stacks up and why first-time relief exists
The math is steep. A taxpayer who owes $10,000 and files three months late faces a penalty equal to 15% of that balance before interest. The IRS calculates the failure-to-file charge at 5% of unpaid tax per month or partial month, capped at 25%. When both the failure-to-file and failure-to-pay penalties apply in the same period, the filing penalty is reduced so the two do not fully stack, but the combined cost still climbs fast.
The agency recognizes that penalties sometimes hit taxpayers who have otherwise followed the rules. Its Penalty Handbook in the Internal Revenue Manual instructs employees to evaluate relief requests under four categories: reasonable cause, statutory exception, administrative waiver (also called First Time Penalty Abate, or FTA), and IRS error. The FTA route stands out because it does not require the filer to prove illness, a natural disaster, or any other qualifying event. A taxpayer who has filed on time and paid in full for the three prior tax years can qualify simply by asking.
In practice, the first-time waiver serves two policy goals. It encourages taxpayers who have fallen behind to come back into the system by softening the immediate financial hit, and it rewards consistent compliance by reserving this one-time break for people who have a strong filing record. The IRS also benefits administratively: granting standardized relief on a clean-history test is faster than evaluating thousands of individual hardship stories one by one.
Form 843, Treasury regulations, and what the IRS actually reviews
Filers who want to request abatement in writing use Form 843, most recently revised in December 2024 according to the IRS instructions for that form. The form asks for the type of penalty, the tax period, and a written explanation. Treasury Regulation 26 CFR 301.6651-1, which interprets Internal Revenue Code Section 6651, requires the taxpayer to make an “affirmative showing of facts” supporting reasonable cause, typically through a written statement, according to the regulation text published by Cornell Law School.
That regulatory language matters because it draws a line between two different strategies. A taxpayer claiming reasonable cause needs to show that ordinary care and prudence still led to the late filing. The IRS lists qualifying circumstances: death or serious illness of the taxpayer or an immediate family member, inability to obtain records despite timely effort, natural disasters, and system issues. Reliance on a tax professional or general lack of knowledge about filing requirements does not qualify, according to the agency’s own reasonable cause guidance.
A filer pursuing the FTA path, by contrast, does not need to prove any of those events. Instead, the IRS looks at a narrow set of objective criteria. For the tax year in question, the return must be filed, even if it was late. For the three prior years, there must be no significant penalties for late filing or late payment. And the taxpayer must have paid, or arranged to pay, the underlying balance due through full payment, an installment agreement, or another approved resolution.
Because the IRS evaluates first-time abatement largely through its internal account history, the written narrative on Form 843 is usually brief. Practitioners often identify the specific tax year and penalty, state that the taxpayer meets the clean-compliance test for the prior three years, and explicitly request administrative waiver under the first-time abatement policy. If the IRS account transcript confirms eligibility, the agency can remove the penalty without weighing any hardship explanation.
How to ask the IRS for first-time penalty abatement
Taxpayers can request FTA in several ways. Many start by calling the IRS and asking for removal of the failure-to-file penalty under the first-time abatement criteria. Phone representatives have authority in many cases to check the prior-year history and grant relief immediately. Others prefer to submit Form 843 by mail, especially when multiple tax periods or penalty types are involved or when they want a written record of the request and outcome.
Timing also matters. The IRS generally considers abatement requests after a penalty has been assessed, which usually happens soon after a late-filed return posts to the account. Interest that accrued on the penalty is typically reduced when the underlying penalty is removed, but interest on the original tax still runs until that tax is paid in full. For taxpayers who cannot pay immediately, setting up an installment agreement can help satisfy the “paid or arranged to pay” element while they pursue FTA.
First-time abatement is not a cure-all. Taxpayers who have prior penalties in the last three years or who face multiple years of noncompliance often have to rely on reasonable cause instead, with its stricter factual showing. But for those who have one bad year after a long history of filing on time, the policy can turn an intimidating penalty notice into a manageable bill, and in some cases, erase the late-filing charge entirely.
