IRS Form 843 Instructions

In some situations, the federal government may collect more revenue than it’s otherwise entitled to. Other times, taxpayers may have made a mistake or have paid penalties, interest, or additional taxes that they shouldn’t have paid. In certain tax situations, the Internal Revenue Service may consider administrative relief for taxpayers who file IRS Form 843.

This article will walk you through the basics of this tax form, including:

  • When you should file Form 843
  • When you should NOT file Form 843
  • How to complete and file Form 843 with the Internal Revenue Service

Let’s start with some step by step instructions on IRS Form 843.

How do I complete IRS Form 843?

This one-page tax form is relatively straightforward, and should be simple for most taxpayers to fill out. Let’s start with the taxpayer information at the top of the form.

Taxpayer information

In the taxpayer information fields, you’ll need to provide the following, as shown on the applicable tax return:

  • Taxpayer name
  • Taxpayer Social Security number (SSN)
  • Address, including city, state and zip code
  • Employer identification number (EIN)
  • Daytime telephone number

If you are a married couple filing a joint return, you will need to provide SSNs for both spouses. If you have an individual taxpayer identification number (ITIN) instead of an SSN, you may use that instead.

Refund or abatement request

The request itself has 7 lines. Since there are specific instructions, we’ll go through each line, one at a time.

Line 1: Tax period

Enter the tax period or tax year for which you are applying. If you are applying for a prescription brand refund, write the fee year in the ‘From’ line.

If you have multiple tax periods or more than one tax period, you must submit a separate Form 843 for each one.

Line 2: Amount to be refunded or abated

Enter the amount that you expect the IRS to refund or abate.

Line 3: Type of tax or fee

In Line 3, enter the tax type or the type of fee to be refunded/abated, or to which the interest, penalty, or additional tax is related. The IRS allows you to choose from the following:

  • Fee

There are additional instructions for certain situations.

Excess tier 2 RRTA

Line 5: Interest, penalties, and additions to tax

Check any box that applies. If none apply, skip Line 5 and proceed directly to Line 6.

If interest was assessed because of IRS errors or delays

The IRS can abate interest on assessed tax as a result of IRS error, but only if:

  • There was an unreasonable delay or error that occurred during the processing of your case
  • You did not have anything to do with the delay or error

Additionally, the interest can only be abated in tax cases where a notice of deficiency is required. This includes:

  • Income tax
  • Generation-skipping transfer tax (GSTT)
  • Estate and gift taxes
  • Certain excise taxes

To request an abatement of interest on a tax,

  • Write “Request for Abatement of Interest Under Section 6404(e)” at the top of Form 843
  • Complete Lines 1 through 3
  • Check the first box on Line 5a, then show dates of any interest payment or tax payment on Line 5b
  • On Line 7, state the following:
    • The type of tax involved
    • When you first received a written IRS notice about the tax deficiency
    • The specific period for which you are requesting abatement of interest,
    • The circumstances surrounding your tax case, and
    • Why you believe that failure to abate the interest would result in grossly unfair treatment
Requesting abatement or refund of a tax as a result of erroneous written advice

If you received erroneous advice from an IRS official that increased your tax liability, the IRS may abate or refund any part of tax penalties or addition to tax that occurred.

The IRS will abate the penalty or addition to tax only if:

  • You reasonably relied on the written advice
  • The written advice was in response to a specific written request for advice made by you (or your representative who is allowed to practice before the IRS), and
  • The penalty or addition to tax did not result from your failure to provide the IRS with adequate or accurate information.

Treasury Regulations 301.6404-3 contains more detail.

To request an abatement or refund of a penalty or addition to tax because of erroneous written advice, do the following:

  • Write “Request for Abatement of Penalty or Addition to Tax Under Section 6404(f)” at the top of Form 843
  • Complete Lines 1 through 4
  • Check the second box on Line 5a. On Line 5b, enter the date of any tax payment you may have made
  • Attach the following to your Form 843:
    • Your written request for advice
    • The erroneous written advice that the IRS provided you
    • Any report of tax adjustments that identify the tax penalty or addition to tax related to the erroneous advice

Line 6: Original return

Check the appropriate tax return type for which the tax, interest, penalty, or addition to tax applies.

Line 7: Explanation

Provide a written explanation of the tax issues and state why you believe that the IRS should approve this claim or request. If you have additional information that you cannot include on the form itself, or you need to attach additional pages, be sure to include the following information on each page:

  • Taxpayer name
  • Taxpayer ID number: SSN, ITIN, or EIN
