• Form 843, “Claim for Refund and Request for Abatement,” is the IRS form used to request a refund of certain taxes not handled through amended income/employment returns and to ask the IRS to abate (remove) interest, penalties, or additions to tax assessed in error.
– Use Form 843 for certain non-income-tax issues (penalties, interest, some excise or trust fund amounts, etc.). It is not a substitute for amended income-tax or employment-tax returns—use the appropriate amended return (for example, Form 1040-X or Form 941-X) when those apply.
– File a separate Form 843 for each tax type and tax year/period. Time limits generally are two years from the date you paid the tax or three years from the date the return was filed, whichever is later.
– If the IRS denies your claim (statutory notice of claim disallowance) or if six months pass without action, you may sue in U.S. District Court or the U.S. Court of Federal Claims. You may also file a protective claim to preserve your refund rights while your facts develop.
What is Form 843 and when is it used?
Form 843 is a multipurpose IRS form used to:
– Claim a refund or credit of certain taxes, interest, penalties, or additions to tax that you believe were assessed or collected in error.
– Request abatement (removal) of interest or penalties that you believe were applied incorrectly (for example, because of IRS delay or error).
Common situations where taxpayers use Form 843:
– You were assessed penalties or interest that you believe resulted from IRS error, processing delay, or incorrect assessment.
– An employer withheld Social Security or Medicare tax in error and will not correct it (in some cases a Form 843 claim is used when other employer remedies are exhausted).
– You paid certain excise taxes or other non-income taxes and believe you are due a refund.
Note: Many matters involving income tax or employment tax adjustments must be handled on the specific amended return forms (for example, use Form 1040-X to amend a personal income tax return or Form 941-X to correct an employment tax return). Form 843 is not the vehicle to amend those returns.
Who can file Form 843?
– The taxpayer who paid the tax, penalty, or interest.
– An authorized representative (power of attorney) may file on behalf of a taxpayer; include Form 2848 (Power of Attorney and Declaration of Representative) or other evidence of authority.
– Estate representatives, fiduciaries, or legal representatives where appropriate.
Important limitations and points to know
– File a separate Form 843 for each tax or fee type and for each tax year or period.
– The statute of limitations: generally you must file within two years from the date you paid the tax or three years from the date the return was filed, whichever is later (see IRS Publication 556 for details).
– If the IRS determines your claimed refund is excessive, it may impose a penalty equal to 20% of the amount found to be excessive.
– Form 843 cannot be used to “amend” a previously filed income or employment tax return—use the proper amended return form (e.g., Form 1040-X, Form 941-X, etc.) for those corrections.
– For penalty abatement requests, you should identify the Internal Revenue Code (IRC) section or penalty type you are asking to have abated—use the code/notice information from the IRS notice you received (the form instructions tell you where to enter that information).
How to file Form 843 — step-by-step practical guide
1. Confirm this is the correct form
• Review the IRS notice or tax assessment that prompted your claim and confirm whether the issue is handled by Form 843 or by an amended return. If the notice references a code or offers appeal rights, follow the notice instructions and consider Form 843 only if it matches the types of claims described in the form instructions.
2. Gather documentation
• IRS notices and correspondence that led to the claim.
• Proof of payment (proof you paid the tax/penalty/interest) if claiming a refund.
• Employer correspondence if related to withheld taxes.
• Records showing IRS delay or error (dates, phone call notes, receipts, transcripts).
• Any computations that show how you calculated the refund or abatement amount.
• Power of attorney (Form 2848) if an authorized representative will act on your behalf.
3. Complete the form accurately
• Provide identifying information (name, address, Social Security or EIN, tax period).
• Enter the type of tax or fee you are claiming for and, for penalty abatement, the IRC section or penalty code as stated on the IRS notice.
• Include a clear statement of the facts and the specific request: whether you request abatement of a penalty or interest, or a refund of a paid amount, and the dollar amount sought.
• Choose or explain the reason(s) for the abatement/refund. Common reasons include erroneous assessment by the IRS, IRS delay causing damage, reasonable cause for failure to comply, or other administrative relief; support your reason with facts and evidence.
• Attach additional pages if you need more space for explanation and evidence.
4. Attach supporting evidence and computations
• Submit copies (not originals) of supporting documents: receipts, canceled checks, wage statements, IRS notices, transcripts, medical records (if claiming reasonable cause for illness), or other relevant documents.
• Provide clear calculations demonstrating how you arrived at the refund or abatement amount requested.
5. Mail the form to the correct IRS address
• Form 843 must generally be mailed to the mailing address shown in the form’s instructions (addresses vary by the type of claim and where you live). Consult the Form 843 instructions on IRS.gov for the proper mailing address.
• Keep copies of the completed form and all attachments for your records, and send the package via a trackable mail method if you want delivery confirmation.
6. What to expect after filing
• The IRS may request additional information or documentation.
• The IRS will approve, partially approve, or deny the claim. If approved, you may receive a refund or an abatement of the assessed penalties/interest.
• If the IRS takes no action for six months or issues a statutory notice of claim disallowance, you may sue in federal court (U.S. District Court or Court of Federal Claims) to recover the amount claimed.
• If you believe your claim is timely but facts are still developing, consider filing a protective claim (labeled as such) to preserve rights while you assemble additional evidence. Protective claims and so-called “real” claims have the same legal effect for preserving the statute of limitations.
Special considerations and common pitfalls
– Separate form for each claim: File one Form 843 per tax type and per tax year or period.
– Time limits: Carefully track payment dates and return filing dates; missing the statute of limitations can bar your claim.
– Proper documentation: Unsupported or vague claims are likely to be denied. Provide clear evidence and a well-reasoned explanation.
– Excessive-claim penalty: If the IRS believes you claimed more than you were entitled to, it can assess a penalty equal to 20% of the excessive portion—don’t overstate your claim.
– Appeals and court action: If denied, follow the appeals instructions in the IRS notice (you can generally sue after a statutory disallowance or after waiting six months).
– Representation: If you use a representative, file Form 2848 or attach proof of authority to act.
Example scenarios (illustrative)
– IRS delay: You mailed required documents to the IRS, the agency delayed processing for an extended period, a penalty or interest was assessed due to the delay, and you believe that assessment resulted from IRS delay — you may request abatement on Form 843 with documentation of the delay and its effect.
– Erroneous penalty: The IRS assessed an accuracy-related penalty based on incorrect information; you have documentation proving the assessment was in error — request abatement and provide the correct documents.
– Overwithheld Medicare/SS: Your employer will not refund excess Social Security or Medicare withholding, and you qualify to seek a refund directly from the IRS — a Form 843 claim may apply (confirm the correct procedure for the specific withholding situation).
