IRS Form 843 – Claim for Refund & Request for Abatement

In 2023, the IRS assessed more than $13 billion in penalties, and many taxpayers paid fines they could have reduced or avoided entirely. If you’ve been hit with an unexpected IRS notice or believe you’ve overpaid taxes, IRS Form 843 could be your solution. This form allows you to request a tax refund, seek penalty abatement, or ask the IRS to correct IRS errors that caused extra interest or fees.

Form 843 is officially titled the Claim for Refund and Request for Abatement. It is not used for regular income tax refunds, which require an amended tax return (Form 1040-X). Instead, this form applies when you want to recover taxes paid due to mistakes, request relief from specific penalties, or dispute interest charges caused by IRS processing delays. It also covers situations like excess Social Security or Medicare tax withheld, employment taxes issues, and even unique fees like the branded prescription drug fee.

The value of this form is clear: filing Form 843 correctly could save you hundreds or even thousands of dollars. The IRS will not automatically adjust your account—you must request relief in writing and provide evidence supporting your claim. In this guide, we’ll explain what Form 843 is, why you may have received a notice, the risks of ignoring penalties, and step-by-step options to get relief or a refund.

What Is IRS Form 843?

IRS Form 843, officially known as the Claim for Refund and Request for Abatement, is the IRS form used when you need to correct certain tax situations outside of a typical amended tax return. Taxpayers use this form to request a tax refund, reduce penalties, or challenge interest assessed due to IRS errors.

Form 843 is not meant for regular income tax refunds related to a personal or individual income tax return—those require Form 1040-X. Instead, this form is designed for specific circumstances involving certain taxes and fees. Examples include:

• Employment taxes: Claim back FICA tax, RRTA tax, or other employment taxes that were incorrectly withheld.
  
  
• Excess Social Security or Medicare tax: Recover overpaid Medicare tax withheld or duplicate taxes withheld by multiple employers.
  
  
• Excise taxes and fees: Request refunds related to branded prescription drug fees, annual fees for health insurance providers, or other industry-specific assessments.
  
  
• Penalties and interest: Ask for penalty or interest abatement when you can show reasonable cause or erroneous written advice from the IRS.
  
  
• Exceptional cases: File on behalf of a deceased taxpayer or to claim unused credit for a prior tax year.

By filing Form 843, you formally ask the IRS to review the tax involved and correct any overpayment, improper penalty imposed, or fees charged in error. It is an essential step toward protecting your rights as a taxpayer and recovering money you may not actually owe.

Why Did You Receive an IRS Notice?

Receiving an IRS notice can feel stressful, but understanding why it was issued is the first step toward resolving the problem. These notices often inform you of IRS penalties, tax overpayments, or balances due. In many cases, they trigger filing IRS Form 843 to request a refund or penalty abatement.

Common Reasons You May Need Form 843

You may need to file Form 843 if:

• IRS errors or delays: These occur when processing mistakes or incorrect written advice cause interest or penalties that you should not owe.
  
  
• Taxes withheld incorrectly: You paid excess Social Security, Medicare tax withheld, or other employment taxes that your employer cannot refund.
  
  
• Trust fund recovery penalty: As a business owner, you were assessed a trust fund recovery penalty and need to challenge the determination.
  
  
• Reasonable cause situations: You were impacted by a natural disaster, medical emergency, or other events beyond your control, and you can document your circumstances.
  
  
• Tax preparer mistakes: Errors on a prior tax return led to overpayment, penalties, or misapplied taxes paid.

Consequences of Ignoring IRS Notices

Ignoring an IRS notice can make the situation worse. Unresolved issues may grow into serious tax debt with additional penalties imposed and civil penalty charges. Interest continues to accrue daily, increasing your overall balance. Sometimes, the IRS may initiate collection actions such as liens, levies, or wage garnishments. Filing Form 843 quickly can stop additional charges and start resolving your account.

Relief and Resolution Options

If you received an IRS notice or believe you have overpaid, there are several ways to get relief. IRS Form 843 is one of the most effective tools for requesting penalty relief or claiming a tax refund. Understanding the types of relief available helps you choose the right approach and avoid unnecessary costs.

Abatement vs Refund

Form 843 can be used for two distinct purposes:

‍

‍

This distinction matters because the IRS processes abatements and refunds differently. Filing the proper request avoids processing delays.

Other Resolution Options

In some cases, you may need more than Form 843:

• First-Time Penalty Abatement: The IRS may automatically remove specific penalties if you have a clean compliance history.
  
  
• Interest Abatement: You can request interest abatement if the IRS caused an unreasonable processing delay or made an error.
  
  
• Payment Plan: If you still owe after abatement, you may qualify for an IRS payment plan or installment agreement to resolve your tax debt over time. See our [Installment Agreement Guide] for details.

When to Get Professional Help

If you owe a large balance or have multiple years of issues, consult a tax attorney or tax professional. They can prepare a strong request for abatement, address penalty relief requests, and represent you before the IRS.

How to File Form 843

Filing IRS Form 843 correctly is essential to avoid delays or denials. The process involves gathering documentation, completing each section carefully, and sending it to the correct IRS office.

Before You File

Start by collecting all relevant documents:

• Your personal income tax return or individual income tax return for the tax year
  
  
• Records of taxes paid, W-2s, and payment confirmations
  
  
• The original IRS notice or letter showing the penalty imposed or interest assessed
  
  
• Any supporting proof, such as employer statements for employment taxes or medical records for reasonable cause claims

Verify that you are within the deadline: generally three years from filing your tax return or two years from payment.

Where to Send Your Form

The mailing address depends on your situation. If responding to an IRS notice, use the address on it; otherwise, mail it to the IRS service center where you would typically file your current-year return. Double-check the correct mailing address on IRS.gov before sending it.

Avoiding Common Mistakes

• Wrong form used: Do not use Form 843 for regular income tax refunds — file an amended tax return (1040-X) instead.
  
  
• Incomplete documentation: Missing proof leads to denial.
  
  
• Combining years: Submit a separate form for each tax year or issue.

Filing accurately the first time increases the chance of a successful result and helps prevent additional assessed penalties or processing delays.

Professional Help and Resources

While many taxpayers can file IRS Form 843 independently, certain situations benefit from professional guidance. A tax professional or attorney can strengthen your case and help you avoid costly mistakes, especially if your problem involves multiple tax years, large tax debt, or complex penalty relief requests.

When to Hire a Professional

You should consider expert help if:

• You face a trust fund recovery penalty or other business-related civil penalty.
  
  
• Your case involves net operating loss carrybacks, unused credit, or other complex calculations under the tax code.
  
  
• You have been assessed a significant interest or multiple years of penalties, and you need a strong request for abatement with detailed documentation.
  
  
• You are unsure which tax forms or Internal Revenue Code sections apply to your case.

Resources from the IRS

Even if you choose to file yourself, use these IRS tools:

• Account transcripts: These show payments, penalties, and taxes paid.
  
  
• Wage and income transcripts: These verify reported income and employment taxes withheld.
  
  
• Where to File tool: This confirms the correct mailing address for Form 843.

A professional can also negotiate an IRS payment plan or installment agreement if you still owe a balance after penalty relief. This keeps you in compliance and stops further collection action.

Can I use Form 843 to refund the branded prescription drug fee?

If you overpaid the branded prescription drug fee, you may file Form 843 to claim a tentative refund. You must include documentation showing the amount paid and cite the applicable tax law section.

Are there limits to using Form 843 for interest abatement?

You can only request interest abatement if the IRS caused a delay or error. Your claim must include proof of IRS mistakes and specify the affected tax period.
