IRS Penalty Abatement Guide

What Is Penalty Abatement?

IRS penalties can add 20–25% to your tax balance — sometimes more. Penalty abatement is the process of requesting that the IRS reduce or eliminate those penalties. The IRS has two main abatement programs: First-Time Penalty Abatement (FTA) and Reasonable Cause abatement. Most taxpayers qualify for at least one of these programs, but the IRS does not proactively offer them — you must request abatement explicitly.

First-Time Penalty Abatement

First-Time Penalty Abatement (FTA) is the easiest and most reliable abatement program. To qualify, you must: (1) have no penalties in the three prior tax years, (2) have filed all required returns or filed a valid extension, and (3) have paid or arranged to pay any tax due. If you meet these criteria, the IRS will abate failure-to-file and failure-to-pay penalties for the year in question — no explanation required. FTA is available by phone call to the IRS or in writing.

KDA's experience: approximately 60% of our clients who owe IRS penalties qualify for FTA. For a taxpayer with $50,000 in unpaid tax, FTA can eliminate $12,500 or more in penalties before any payment plan begins.

Reasonable Cause Abatement

If you do not qualify for FTA, you may still qualify for reasonable cause abatement if you can demonstrate that you exercised ordinary business care and prudence but were unable to comply. Qualifying circumstances include: serious illness or death of the taxpayer or immediate family member, natural disaster, reliance on incorrect advice from the IRS or a tax professional, and inability to obtain records necessary to file. The IRS evaluates reasonable cause requests on a facts-and-circumstances basis — a well-documented, professionally written request significantly improves approval odds.

How to Request Abatement

FTA can be requested by calling the IRS at 1-800-829-1040 or by writing a letter to the IRS service center that issued the penalty notice. Reasonable cause requests should always be submitted in writing with supporting documentation. KDA prepares penalty abatement requests as part of our standard representation — we know which arguments the IRS accepts and how to present them. A poorly written abatement request that is denied can make a subsequent request harder to approve.

California FTB Penalty Abatement

California FTB has its own penalty abatement program. The FTB offers a one-time penalty abatement for taxpayers with a clean compliance history — similar to the IRS FTA program. The FTB also accepts reasonable cause arguments. California penalties can be substantial: the FTB charges a 5% failure-to-file penalty plus 0.5% per month (up to 25%), and a 25% penalty for substantial understatement of tax. KDA files FTB abatement requests simultaneously with IRS requests when clients have penalties with both agencies.

How Much Can You Save?

Note: Interest is not abatable under FTA — only penalties. However, reducing the penalty balance also reduces the interest that accrues on that balance going forward.
