IRS Form 843: How to Claim a Refund or Request Penalty Abatement

What Form 843 is used for

Form 843, Claim for Refund and Request for Abatement, lets you ask the IRS to refund or reduce certain taxes, penalties, interest and fees you should not have to pay. It is a written petition you use when no other specific form applies to your situation.

People commonly file Form 843 to:

• Request abatement of a failure-to-file or failure-to-pay penalty based on reasonable cause
• Recover excess Social Security or Medicare tax withheld by a single employer that will not fix it
• Claim a refund of interest that built up because of an IRS error or delay
• Ask the IRS to remove interest or penalties tied to certain non-income taxes

Form 843 does not cover everything. You cannot use it to abate income, estate or gift tax, to claim an income tax refund or to amend a return. Employers cannot use it for FICA, RRTA or income tax withholding, and those corrections go on the matching "X" form instead.

Where to mail Form 843

There is no single address for Form 843. Where you send it depends on why you are filing and whether you received an IRS notice.

Use these guidelines to route your form correctly:

• Responding to an IRS notice: Mail it to the return address printed on that notice.
• Penalty abatement or most other reasons: Send it to the IRS service center where you would file a current-year return for the related tax.
• Estate or gift tax matters (Form 706 or 709): Mail it to the IRS office in Florence, Kentucky listed in the instructions.
• Excess Social Security or Medicare tax as a nonresident alien: Follow the address in IRS Publication 519.

Because timing matters, send Form 843 by certified mail with a return receipt requested so you have proof of the date. Generally you must file within three years of filing the related return or two years of paying the tax, whichever is later.

Can Form 843 be filed electronically or faxed?

For almost all filers, Form 843 cannot be e-filed and is not accepted by fax. You complete the paper form and mail it to the correct address, and most consumer tax software does not support it.

If the IRS asked you to respond to a specific notice, follow the response method described on that notice. When in doubt, mailing a signed paper form to the address tied to your tax or notice is the safe route.

What the IRS accepts as reasonable cause

Reasonable cause means something outside your control kept you from meeting a tax obligation on time. The IRS weighs each request on its own facts, so a clear timeline and supporting documents matter.

Situations the IRS often accepts include:

• Serious illness, hospitalization or a death in your immediate family
• A fire, natural disaster or other casualty you could not avoid
• An inability to get records you needed despite reasonable effort
• Reliance on incorrect written advice from the IRS

A simple lack of funds usually is not enough on its own, though the reason you could not pay can support your case. Explain your circumstances in detail on line 8 of the form and attach evidence.

First-time penalty abatement

If your penalty is a first slip rather than a pattern, you may qualify for First Time Abate. This administrative waiver can remove failure-to-file, failure-to-pay and failure-to-deposit penalties for a single tax period, though it does not erase the underlying tax.

You generally qualify when all of the following are true:

• You have no penalties for the three tax years before the one in question.
• You have filed all required returns or a valid extension.
• You have paid or arranged to pay any tax you owe.

First Time Abate does not cover accuracy-related or fraud penalties. You can often request it by phone using the number on your notice, and the IRS increasingly applies this relief automatically when its records show you qualify.

Refunds of excess Social Security or Medicare tax

Form 843 helps here only in a narrow case. Use it when one employer withheld too much Social Security or Medicare tax and will not adjust or refund the overcollection.

If you had too much Social Security tax withheld because you worked for two or more employers, do not use Form 843. You claim that excess as a credit on your Form 1040 instead. When you do file Form 843, attach your Form W-2 and, if you can, a statement from the employer.

How long Form 843 takes to process

The IRS does not publish a guaranteed processing time for Form 843, and timelines vary with the type of claim and current IRS workload. Many filers wait several months for a decision, and complex or incomplete claims take longer.

A detailed line 8 explanation and complete supporting documents give your claim the best chance of moving quickly. Keep a copy of everything you send in case the IRS asks for more information.
