Form 843 Claim for Refund and Request for Abatement Checklist
Purpose of Form 843
Form 843 serves as the official IRS document for requesting refunds, abatements, or adjustments related to various types of tax assessments, penalties, interest, or fees. Taxpayers, organizations, or their authorized representatives use this form to correct errors, claim refunds, or seek relief from incorrect or excessive IRS charges. The form addresses specific categories of tax-related issues that cannot be resolved through other standard tax forms.
Understanding Form 843 Applications
Form 843 applies to certain taxes, penalties, additions to tax, interest, and fees; however, it does not serve as a universal refund request form. The IRS specifies that Form 843 cannot be used to request abatement of income, estate, or gift tax. Similarly, taxpayers cannot use this form to request refunds of income tax or Additional Medicare Tax.
Employers are prohibited from using Form 843 to request refunds or abatements of Federal Insurance Contributions Act tax, Railroad Retirement Tax Act tax, or income tax withholding. The form also cannot be used to amend previously filed income or employment tax returns or to claim refunds of agreement fees, offer-in-compromise fees, or lien fees.
Step-by-Step Procedure for Completing Form 843
Step 1: Verify Eligibility and Select Reason
Check the appropriate box at the top of Form 843 indicating your specific reason for filing. Available options include abatement or refund of certain taxes, penalties due to reasonable cause, interest caused by IRS error or delay, Trust Fund Recovery Penalty, penalties for incorrect appraisals or misuse of dyed fuel, refunds of employee social security or Medicare tax withheld in error or in excess, branded prescription drug fees, annual fees on health insurance providers, and other qualifying circumstances. Ensure your situation qualifies for Form 843 rather than requiring a different tax form.
Step 2: Provide Complete Identification Information
Enter your complete name as it appears on your tax records. If the claim relates to a joint return, include your spouse’s name from that return. Provide your taxpayer identification number, which may be a Social Security Number, Individual Taxpayer Identification Number, or Employer Identification Number, depending on whether you are filing as an individual or business entity. If filing regarding a joint return, include both spouses’ identification numbers.
Enter your current mailing address, including apartment or suite number, city, state, and ZIP code. For foreign addresses, include the complete international address, including the country name, province or state, and foreign postal code.
Step 3: Specify Tax Period and Amount
Enter the tax period or fee year for which you are making the claim, providing both beginning and ending dates. If requesting a refund of a branded prescription drug fee, enter the fee year on the beginning date line. Prepare a separate Form 843 for each distinct tax period or fee year unless your situation qualifies for one of the exceptions outlined in the instructions. Enter the total dollar amount you are requesting to be refunded or abated on the designated line.
Step 4: Document Payment Information
Enter the specific date or dates of each payment for which you are requesting a refund. If you have made multiple payments and need additional space beyond what the form provides, attach supplementary sheets containing this information. Include your name and taxpayer identification number on any attached sheets to ensure proper processing.
Step 5: Identify Tax or Fee Type
Check the appropriate box or boxes on Line 4 to indicate the type of tax or fee involved in your claim. Available categories include employment tax, estate tax, gift tax, excise tax, income tax, fees, and civil penalties. If your claim relates to interest, a penalty, or an addition to tax, check the box indicating the underlying tax or fee type to which the claim relates. Generally, check only one box, unless your situation falls under specific exceptions detailed in the “Special Situations” section of the instructions.
Step 6: Specify Return Type
On Line 5, check the box identifying the type of fee or return filed that relates to your claim. Options include Forms 706, 709, 940, 941, 943, 944, 945, 990-PF, 1040, 1120, 4720, and CT-2, as well as branded prescription drug fees and other specified returns. Check the box labeled “1040” to indicate other individual income tax returns, such as Form 1040-SR, 1040-NR, or the Spanish-language version of Form 1040.
Step 7: Cite Applicable Code Section
If your claim involves a penalty, enter the applicable Internal Revenue Code section on which the penalty is based on Line 6. You can typically find this code section on the Notice of Assessment or other correspondence you received from the IRS. This information helps the IRS process your claim accurately and efficiently.
Step 8: Select Reason for Request
Check the appropriate box on Line 7 that best describes your reason for requesting the refund or abatement. The available options are: interest assessed due to IRS errors or delays, penalties or additions to tax resulting from incorrect written advice from the IRS, reasonable cause or other legally permitted reasons, or the option that none of the listed reasons apply. Select only the box that accurately represents your circumstances.
Step 9: Provide Detailed Explanation and Computation
On Line 8, provide a comprehensive explanation of why you believe your claim should be allowed. Include details about the circumstances leading to your request, relevant facts supporting your position, and applicable legal provisions or regulations. Show your complete computation, demonstrating how you calculated the amount shown on Line 2.
If you require additional space for your explanation, please attach supplementary sheets with your name and taxpayer identification number clearly indicated on each page. Include all relevant supporting documentation, such as payment records, IRS notices, correspondence, examination reports, or other evidence substantiating your claim.
Step 10: Attach Supporting Documentation
Compile and attach all relevant documentation supporting your claim. Required attachments may include copies of Forms W-2 proving amounts withheld, payment receipts or canceled checks, IRS notices or letters, examination reports, prior interest computations provided by the IRS, written requests for advice and the IRS’s written responses if claiming penalty abatement due to erroneous advice, proof of payment for Trust Fund Recovery Penalty claims, and any other documents relevant to your specific claim type.
For claims involving authorized representatives, attach the original or a copy of Form 2848, Power of Attorney and Declaration of Representative.
Step 11: Obtain Required Signatures
Ensure all applicable parties sign Form 843 under penalties of perjury. If filing a claim relating to a joint return, both you and your spouse from that return must sign the form. For corporate filings, a corporate officer authorized to sign must execute the form and include their official title with the signature.
For estates or trusts, the fiduciary must sign the form. If the IRS has issued an Identity Protection PIN to you or your spouse, enter these PINs in the designated fields on the signature section of the form.
Step 12: Complete Paid Preparer Section
If a paid tax return preparer completes Form 843 on your behalf, that preparer must sign the form and provide complete identifying information in the Paid Preparer Use Only section at the bottom of the form.
Required information includes the preparer’s name, signature, date, Preparer Tax Identification Number, firm name, firm Employer Identification Number, firm address, and telephone number. The preparer must provide you with a copy of the completed Form 843 for your records.
Individuals who prepare the form without charging a fee should not complete this section.
Step 13: Submit Form to Appropriate IRS Address
Mail the completed Form 843 along with all supporting documentation to the appropriate IRS address based on your specific situation. If you are responding to an IRS notice, mail the form to the return address shown on that notice.
For estate and gift tax matters involving Forms 706 or 709, send the form to the IRS at 7940 Kentucky Drive, Florence, KY 41042-2915, Attention E&G, Stop 824G.
For branded prescription drug claims, use the address provided in Letter 4658. For annual fee on health insurance providers, use the address shown in Letter 5067C. For requests with a net interest rate of zero, mail to the service center where you filed your most recent return. For all other situations not specifically addressed above, send the form to the service center where you would file a current-year tax return for the tax type to which your claim relates.
Essential Rules and Considerations
Authorization and Representation Requirements
You may file Form 843 personally or have an authorized representative file it on your behalf. When an authorized representative submits the form, you must attach either the original or a copy of Form 2848, Power of Attorney and Declaration of Representative.
You must sign Form 2848 to authorize the representative to act on your behalf specifically for purposes of the refund or abatement request. The representative must have proper authority under applicable IRS rules governing representation before the agency.
Signature Requirements and Authority
Signatures are required from the appropriate parties, depending on the nature of the claim and the type of taxpayer. Individual taxpayers must sign their own tax forms unless they are properly represented. For claims relating to joint returns, both spouses from the joint return must sign Form 843.
Corporate claims require signatures from corporate officers authorized to sign on behalf of the corporation, and the officer’s title must accompany the signature. Fiduciaries must sign forms filed on behalf of estates or trusts. All signatures are made under penalties of perjury, affirming that the information provided is true, correct, and complete to the best of the signer’s knowledge and belief.
Documentation and Substantiation Standards
Attach comprehensive supporting documentation to substantiate your claim. Required documentation varies based on claim type but typically includes proof of payment, IRS notices or correspondence, examination reports, and records demonstrating the basis for your request.
For employee refund claims involving social security, Medicare, or Railroad Retirement Tax Act taxes, attach copies of Forms W-2 and, when possible, statements from employers detailing amounts previously repaid or reimbursed.
For penalty abatement requests based on erroneous written advice, attach your original written request for advice, the erroneous written advice provided by the IRS, and any reports of tax adjustments identifying the penalty and related items.
Identity Protection PIN Compliance
If the IRS has issued you an Identity Protection PIN, you must enter this PIN in the designated field on Form 843. For claims relating to joint returns where the IRS has issued PINs to both spouses, both PINs must be included in their respective fields.
Identity Protection PINs are six-digit numbers the IRS assigns to taxpayers who have been victims of identity theft or who qualify for the IP PIN Opt-In Program. Failure to include required PINs when issued may delay processing of your claim.
Submission Methods and Processing
Form 843 must be submitted by mail to the appropriate IRS address. There is no electronic filing option available for this form. Determine the correct mailing address based on your specific claim type and circumstances as detailed in the Where To File section of the form instructions.
Mailing addresses vary depending on whether you are responding to a specific IRS notice, the type of tax or fee involved, and your geographic location. Always retain copies of the completed form and all supporting documentation for your records before mailing.
Separate Form Requirements and Exceptions
Generally, you must file a separate Form 843 for each distinct tax period, fee year, or type of tax or fee. However, specific exceptions apply to certain situations. You may file a single Form 843 if the interest assessment resulted from a single IRS managerial or ministerial act affecting multiple tax years or types of tax, such as when multiple years were under examination simultaneously.
Similarly, when requesting a net interest rate of zero on overlapping tax underpayments and overpayments, you do not need separate forms for each tax period involved in the overlapping periods.
Time Limitations for Filing Claims
Generally, you must file a claim for credit or refund within three years from the date you filed your original return or two years from the date you paid the tax, whichever is later. If you do not file within this statutory period, you may lose your right to claim a credit or refund.
Different time limitations may apply to specific types of claims, such as those involving erroneous written advice from the IRS or requests for interest abatement. Review the applicable statute of limitations provisions carefully to ensure timely filing of your claim.
Appropriate Use of Form 843
Use Form 843 only for claims and requests that qualify under the categories specifically listed on the form and in its instructions. Do not use Form 843 for issues requiring different tax forms.
For example, use Form 1040-X for amended individual income tax returns, various X-series forms for employment tax corrections, Form 8849 for excise tax refunds, Form 6118 for tax return preparer and promoter penalty refunds, and Form 8379 for injured spouse allocations.
Using the incorrect form may result in processing delays or rejection of your claim. Refer to the form instructions to determine whether Form 843 is the correct form for your specific situation.
This comprehensive checklist ensures accurate completion and submission of Form 843 while maintaining compliance with IRS requirements for claiming refunds and requesting abatements of qualifying taxes, penalties, interest, and fees.
