Form 843: Claim for Refund and Request for Abatement

Requests Form 843 may cover

• Certain penalty, interest, fee, addition-to-tax, or tax refund and abatement requests allowed by the instructions
• A written penalty-relief request when the IRS cannot resolve an eligible request by phone
• Certain claims involving interest caused by qualifying IRS managerial or ministerial error or delay
• Other specifically permitted claims identified in the current form and instructions

When another form may be required

Form 843 generally is not used to amend an individual income tax return. Form 1040-X is commonly used for that purpose. Employers correcting amounts previously reported on Form 941 generally use Form 941-X rather than Form 843 for the employment-tax adjustment.

The correct procedure depends on the tax, penalty, payment, and reason for the claim. Using the wrong form can delay the request or cause it to be returned.

First-time abatement and reasonable cause are different

• First-time abatement is an administrative waiver for certain penalties when IRS eligibility requirements are met.
• Reasonable cause depends on the taxpayer's facts, timing, ordinary business care and prudence, and supporting evidence.
• The IRS says some penalty-relief requests can be handled by calling the number on the notice. Form 843 may be used for a written request when appropriate.
• Form 843 itself does not create eligibility. The underlying penalty-relief rules still control.

Build a request that can be reviewed

• Identify the penalty or interest charge, tax form, tax period, assessment date, and amount requested.
• Explain what happened in chronological order, including when the problem began, what prevented compliance, and when it ended.
• Connect each statement to records such as medical documents, disaster records, payment confirmations, correspondence, or professional advice.
• Explain the corrective action taken and the steps now used to prevent recurrence.
• Keep a signed copy of the form, statement, attachments, and proof of delivery.

Where to mail Form 843

There is no single mailing address that is correct for every Form 843 request. The proper location can depend on the type of tax, penalty, notice, and IRS office involved. Follow the current Form 843 instructions and any specific directions printed on the IRS notice.

Do not rely on an address copied from an old article or prior form revision. If the instructions and notice appear inconsistent, contact the IRS using the number on the notice before sending sensitive records.

Separate periods and protect refund-claim deadlines

The current instructions generally require a separate Form 843 for each tax period, fee year, or type of tax or fee unless a stated exception applies. Combining unrelated claims can make the request harder to process and review.

Refund claims are also time-sensitive. The instructions generally describe a period of three years from filing the original return or two years from paying the tax, whichever is later, subject to exceptions and claim-specific rules. Confirm the applicable limitation period rather than relying on a general summary.

Complete the explanation as an evidence record

• Use the notice or transcript to identify the tax, return, period, penalty code section, and amount requested.
• Explain the requested computation instead of entering only a total.
• Attach a dated factual statement and records that support each important event.
• If the request follows an IRS notice, include a copy and follow its response instructions when they apply.
• Sign the form, retain a complete copy, and preserve mailing or delivery evidence.
