Form 843

Claim for Refund and Request for Abatement

Used to ask the IRS to remove or reduce certain penalties and interest, or to claim certain refunds.

What it does

Form 843 can be used to request abatement of some penalties and interest. For some first-time penalty situations the IRS accepts a phone call or letter instead, so check the current IRS guidance before mailing the form.

When people use it

  • You want to ask the IRS to remove a penalty for reasonable cause.
  • You believe interest or a penalty was assessed because of an IRS error or delay.

Before you file

  • Write down the reason and gather proof, such as medical records, a disaster notice or correspondence.
  • Check whether the penalty qualifies for the IRS first-time penalty abatement process.
  • Note the tax period and penalty type shown on your notice.

What to watch for

  • Relief is not automatic. The IRS decides based on the facts and your compliance history.
  • Abatement applies to penalties and some interest. It does not cancel the underlying tax.
