Form 843: Claim for Refund and Request for Abatement – 2024 Guide

Form 843 is your tool for getting your money back or reducing what you owe when the IRS has charged you incorrectly—or when you deserve relief. Unlike the more familiar Form 1040-X (which corrects income tax returns), Form 843 handles a specific set of refund and abatement situations involving penalties, interest, employment taxes, excise taxes, and certain fees. Understanding when and how to use this form can save you significant money and hassle.

What Form 843 Is For

Form 843, officially titled ""Claim for Refund and Request for Abatement,"" allows taxpayers to request refunds or abatements (reductions or eliminations) of certain taxes, penalties, interest, fees, and additions to tax. The form serves as your formal written request to the IRS to give you back money you've already paid or to remove amounts the IRS assessed but you haven't yet paid.

What Form 843 can handle:

• Penalties and additions to tax due to reasonable cause, IRS written advice errors, or other lawful reasons
• Interest charges caused by IRS errors or unreasonable delays
• Employment taxes for employees (such as excess Social Security, Medicare, or Railroad Retirement Tax Act taxes withheld)
• Trust Fund Recovery Penalties (when business owners or responsible parties are personally liable for unpaid payroll taxes)
• Excise taxes (though many excise tax refunds require different forms)
• Specialized fees including branded prescription drug fees and annual health insurance provider fees
• Penalty relief for taxpayers with disabilities who couldn't read standard IRS notices

What Form 843 cannot handle:

The IRS is very clear: do not use Form 843 for income tax refunds or corrections (use Form 1040-X instead), employer refunds of FICA or withholding taxes (use Forms 941-X, 943-X, 944-X, or CT-1X), or various excise tax situations requiring Forms 720-X, 4136, or 8849. Using the wrong form causes processing delays, so verify you need Form 843 before filing. IRS Form 843 Instructions

When You’d Use Form 843 (Late Filing/Amended Situations)

You'll typically file Form 843 in response to an IRS notice or after discovering you've overpaid certain taxes or were incorrectly charged penalties or interest. Here are the most common scenarios:

Penalty relief situations

• You received an IRS notice assessing a failure-to-file or failure-to-pay penalty, but you had reasonable cause (serious illness, natural disaster, unavoidable absence)
• The IRS gave you incorrect written advice that led to a penalty
• You qualify for first-time penalty abatement because you have a clean compliance history

Interest abatement situations

• The IRS made an error or unreasonable delay in processing your case, causing additional interest charges
• You have overlapping periods where you simultaneously owed and were owed money (net interest rate of zero request)

Employment tax situations

• Your employer withheld too much Social Security or Medicare tax (more than the annual maximum) but won't refund it
• You worked for multiple employers and collectively paid more than the annual limit
• Social Security or Medicare taxes were withheld from wages that shouldn't have been subject to these taxes

Deadline considerations

Generally, you must file Form 843 within three years from the date you filed your original return or two years from the date you paid the tax, whichever is later. Missing this deadline means you permanently lose your right to the refund. However, some situations have different timeframes—penalty relief requests due to written IRS advice must be filed within the collection statute period. IRS Time Limits

Key Rules or Details for 2024

The December 2024 revision of Form 843 brought a redesigned format, but the fundamental rules remain consistent. Here are the critical requirements:

1. One form per situation rule

File a separate Form 843 for each tax period and type of tax—except when requesting net interest rate of zero (which can cover multiple periods) or interest abatement from a single IRS error affecting multiple years.

2. Signature requirements

• For joint returns, both spouses must sign
• Corporate officers must sign with their title
• Estates and trusts require the fiduciary's signature
• Authorized representatives must attach Form 2848 (Power of Attorney)

3. Documentation is mandatory

Your claim must include detailed explanations and supporting evidence:

• For penalty relief due to IRS written advice: attach your written request for advice, the IRS's erroneous written response, and any assessment notices
• For interest abatement: explain when you were first notified of the deficiency, identify the specific period, and describe the IRS error or delay
• For excess employment taxes: attach employer statements (if obtainable) and copies of all Forms W-2
• For Trust Fund Recovery Penalties: you must first pay the portion attributable to one employee before filing the claim

4. The correct mailing address matters

Where you send Form 843 depends on your situation. If responding to an IRS notice, mail it to the return address on that notice. For penalty relief not related to a notice, send it to the service center where you'd file your current year return. Estate and gift tax claims go to Florence, KY. Branded prescription drug fee refunds go to Ogden, UT. IRS Filing Locations

5. The statute of limitations is strictly enforced

The IRS will not process late claims except in very limited circumstances. Mark your calendar: you have three years from when you filed your return or two years from when you paid the tax to file Form 843.

Step-by-Step (High Level)

Completing Form 843 requires careful attention to detail. Here's a walkthrough of the main sections:

Step 1: Check the correct box at the top

The redesigned 2024 form features checkboxes organized by category (Tax, Penalty, Interest, Other). Select one box that best describes your reason for filing. This determines how the IRS routes and processes your claim.

Step 2: Provide identifying information

Enter your name, Social Security number or Employer Identification Number, and current address. If filing for a joint return, include your spouse's name and SSN. If your address changed since filing the underlying return, also note the old address.

Step 3: Complete Lines 1-4

• Line 1: Enter the tax period (beginning and ending dates) or fee year you're claiming. For branded prescription drug fees, enter the fee year as the beginning date.
• Line 2: State the dollar amount you're requesting as a refund or abatement. Calculate this carefully—it's the total you believe you're owed or should be removed.
• Line 3: If you already made payments, list the payment dates. This helps the IRS match your claim to their records.
• Line 4: Check the box indicating the type of tax or fee (employment, estate, gift, excise, income, fee, or civil penalty).

Step 4: Complete Lines 5-7

• Line 5: Check the form or return type related to your claim (such as Form 1040, 941, 706, 990-PF, etc.).
• Line 6: For penalty claims, enter the Internal Revenue Code section number (found on your IRS notice).
• Line 7: Check the reason for your request: (a) IRS error/delay in interest assessment, (b) penalty from erroneous IRS written advice, (c) reasonable cause or other lawful reason, or (d) none of these apply.

Step 5: Write your detailed explanation (Line 8)

This is the most important section. Provide a complete narrative explaining:

• Why you believe the refund or abatement should be granted
• The specific facts of your situation
• How you calculated the amount on Line 2
• Any legal or regulatory basis supporting your claim

Attach additional sheets if needed, along with all supporting documents (notices, correspondence, W-2s, receipts, etc.).

Step 6: Sign and date

Both spouses must sign if it relates to a joint return. Corporate officers include their title. Your signature declares under penalty of perjury that the information is true and correct.

Step 7: Mail to the correct address

Double-check the instructions for where to file based on your specific situation. Keep copies of everything you submit.

Common Mistakes and How to Avoid Them

Even minor errors can delay processing or result in claim denials. Here are the mistakes the IRS sees most frequently:

Mistake #1: Using Form 843 when another form is required

Many taxpayers mistakenly use Form 843 for income tax refunds (should use Form 1040-X) or employer employment tax corrections (should use Forms 941-X, 943-X, etc.). Solution: Carefully review the ""Do not use Form 843"" section in the instructions before filing.

Mistake #2: Filing without required supporting documentation

Claims without attached evidence are routinely denied. Solution: Create a checklist of required documents for your specific situation. For employment tax refunds, always attach Forms W-2 and employer statements. For penalty relief, attach the IRS notice and any correspondence.

Mistake #3: Missing the statute of limitations deadline

Filing one day late can mean losing thousands of dollars—the IRS has no flexibility on this rule. Solution: Calculate your deadline as soon as you identify a potential claim. Set reminders well before the deadline. If you're close to the deadline, consider mailing via certified mail with return receipt to prove timely filing.

Mistake #4: Inadequate explanation in Line 8

Vague statements like ""I had reasonable cause"" without specific facts lead to denials. Solution: Write as if you're telling your story to someone who knows nothing about your situation. Include dates, specific events, and how they prevented compliance. For reasonable cause penalty relief, explain what happened, when it happened, how it affected your ability to comply, and what steps you took to comply as soon as possible.

Mistake #5: Incorrect mailing address

Sending your form to the wrong address can delay processing by months. Solution: Use the decision tree in the instructions to identify your correct mailing address. When in doubt, mail to the address on your IRS notice.

Mistake #6: Both spouses not signing for joint return claims

The IRS will return unsigned or partially signed forms, losing valuable time. Solution: If your spouse is unavailable or unwilling to sign, you may need to file injured spouse allocation (Form 8379) or explore other options with a tax professional.

Mistake #7: Not keeping copies

You'll need your records if the IRS has questions or if you need to follow up. Solution: Make complete copies of Form 843 and all attachments before mailing. Consider also taking photos or scanning everything for digital backup. IRS Penalty Relief

What Happens After You File

Understanding the IRS processing timeline helps manage expectations:

Initial processing (2-8 weeks)

After mailing Form 843, the IRS first checks that it's complete and routed to the correct department. If anything is missing or unclear, you'll receive a letter requesting additional information. Respond promptly—your claim is suspended until you provide what's requested.

Substantive review (3-6 months typical)

An IRS examiner reviews your claim, supporting documents, and account history. For straightforward penalty relief claims, this may be quick. Complex claims involving multiple tax years, significant dollar amounts, or technical legal issues take longer. The examiner may contact you for clarification or additional documentation.

Decision notification

The IRS will mail you a letter with their decision:

• Approved in full: You'll receive your refund via check or direct deposit (if you provided banking information). For abatement requests, you'll receive confirmation that the penalties or interest have been removed. The related interest on abated penalties is automatically removed as well.
• Partially approved: The IRS agreed with some but not all of your claim. The letter explains what was approved and why the rest was denied. You'll receive a refund for the approved portion.
• Denied: The letter explains the reasons for denial and your appeal rights. You typically have 30 days to appeal to the IRS Office of Appeals.

Processing times vary widely

Simple first-time penalty abatement requests may process in 2-3 months. Interest abatement claims requiring research into IRS procedural history can take 6-12 months. Employment tax refund claims typically process within 3-6 months. If you haven't heard anything after six months, call the IRS number on your original notice or the general helpline.

If you disagree with the decision

You have appeal rights. The denial letter includes instructions for requesting an appeal, typically by filing a written protest within 30 days. The IRS Office of Appeals provides an independent review. If still unsatisfied, you may have the right to file a refund suit in federal court, but consult a tax attorney first—strict rules and deadlines apply.

Interest continues accruing

For abatement requests on unpaid amounts, interest continues accruing on the underlying tax until you pay it in full. Filing Form 843 doesn't stop interest from running—it only requests removal of past interest charges caused by IRS error. IRS Administrative Relief

FAQs

Can I file Form 843 electronically?

Currently, Form 843 must be filed by mail—no electronic filing option exists. This differs from income tax returns and many other IRS forms.

Do I need to pay the disputed amount before filing Form 843?

It depends. For refund claims, you must have already paid the amount you're requesting back. For abatement requests, you typically don't need to pay first—except for Trust Fund Recovery Penalties, which require payment of a ""divisible tax"" (the amount attributable to one employee) before filing.

Can I get first-time penalty abatement automatically?

First-time abate (FTA) is often granted over the phone if you qualify. You need a clean compliance history (no penalties for the prior three years and current with filing/payment requirements). Call the IRS number on your notice first—if they approve it over the phone, you won't need Form 843. If denied or for complex situations, use Form 843.

What if I miss the three-year deadline?

Generally, you lose your right to a refund permanently. However, certain exceptions exist for legally disabled taxpayers, those serving in combat zones, and other specific circumstances. If you're close to the deadline, file immediately and consult a tax professional about possible exceptions.

Will filing Form 843 trigger an audit?

Filing a claim doesn't automatically trigger an examination of your entire return, but the IRS will review the specific items in your claim. They may request additional documentation and could potentially expand the review if they discover other issues. File accurate, well-documented claims to minimize scrutiny.

Can my tax professional file Form 843 for me?

Yes, but they must attach Form 2848 (Power of Attorney) showing you authorized them to represent you. The paid preparer section at the bottom should be completed with their information.

How do I check the status of my Form 843 claim?

Unlike tax refunds, there's no online tracking tool for Form 843. You'll need to call the IRS phone number provided in your original notice or the main IRS helpline (1-800-829-1040). Have your Social Security number, tax period, and the date you mailed Form 843 ready.

This guide is based on the December 2024 revision of Form 843 and current IRS guidance. Tax laws and procedures change periodically, so verify current requirements at IRS.gov/Form843 before filing. For complex claims or significant dollar amounts, consider consulting a tax professional or enrolled agent.
