Form 843 Guidance

Understanding Form 843 is of essential importance in terms of maximizing refunds and claiming excess FICA Tax refunds. At Dimov Tax, we simplify the complexities of the tax filing processes to assist you in maximizing the refunds. Individuals might not be aware of potential refunds that they are missing out on. Applying proper strategies on Form 843 and discovering excess FICA tax refunds could save significant amounts. The details are presented below:

What is Form 843?

Form 843, officially titled “Claim for Refund and Request for Abatement,” is used for claiming refunds or requesting abatements on;

  • Certain taxes, 
  • Interest, 
  • Penalties, 
  • Fees, and 
  • Additions to tax. 

It offers a possibility for overpayments to be rectified and errors made by either the taxpayer or the IRS to be corrected.

Key Points:

  • Form 843 is used to claim refunds or request abatements.
  • It should be avoided using it for income, estate or gift taxes.
  • Employers cannot use it for FICA tax, RRTA tax or income tax withholding.
  • It’s not for amending previously filed income or employment tax returns.

Utilizing Form 843:

  1. Refund of Excess FICA Tax: Taxpayers might be eligible for refunds if they already have overpaid Social Security, Medicare or RRTA (Railroad Retirement Tax Act). Form 843 may assist in reclaiming these excess payments.
  2. Reasonable Cause Claims: In certain situations where penalties or additions to tax have been incurred because of reasonable cause or other reasons permitted under the law, Form 843 offers a platform to request refunds or abatements. This includes situations where errors were made despite exercising due diligence.
  3. Claiming Refund for Erroneous Advice: Penalties may have been imposed thanks to erroneous written advice from the IRS. Form 843 enables refunds or abatements to be requested if such advice was relied upon in good faith.
  4. Abatement of Interest: Form 843 can be used to request abatements in certain situations when interest has accrued due to IRS errors or delays.
    This is particularly applicable when there is an unreasonable error or delays on the IRS’s part and the taxpayer is not at fault.


Eligibility to File Form 843

The most common reason taxpayers file this form is to request abatement of IRS penalties. However, Form 843 could be filed if any of the following situations apply:

  • A refund of any tax other than income, estate, or gift tax that doesn’t come with its own tax refund form is desired.
  • A refund of excess Social Security, Medicare, or RRTA tax withheld from your pay by your employer, and refusal by your employer to issue you the refund is sought.
  • A refund of interest, penalties or tax caused by IRS delays or incorrect written advice by the IRS is desired.
  • A refund of a penalty for misuse of dyed fuel under section 6715 is sought.
  • A refund of a branded prescription drug fee is desired.
  • The belief that interest and penalties have been incorrectly charged by the IRS is held.

  2. Documentation Gathering: All relevant documents should be collected: Including tax forms, notices from the IRS and any other supporting evidence for the claim.
  3. Form Completion: Each section of Form 843 should be carefully filled out with detailed explanations the claims. Thoroughness and accuracy are required to expedite the processing of the request.
  4. Timely Filing: Form 843 should be submitted within the specified timeframe to avoid missing out on potential refunds. Remember, the eligibility also depends on timely filing.

Instructions for Requesting Refund Using Form 843:

  • The form consists of a single page, which is mostly straightforward.
  • Required information includes the name, Social Security number, address, contact details and details of the spouse if applicable.
  • Details about the tax period and the amount sought to have abated should be provided. 
  • In section six, the tax form originally filed by checking the appropriate box should be indicated.


  • Line three: Specify Type of tax or fee should be specified, noting the type of tax if seeking a tax refund (e.g., income, employment, estate), or “fee” should be selected for penalty abatement.
  • On line four, if you selected “fee,” the type of penalty (e.g., “failure to file,” “failure to pay”) should be specified.

Key Points:

  • In section 5a, the reason for the refund or abatement, such as interest assessed due to IRS errors or delays, penalties due to incorrect IRS written advice or reasonable cause, should be stated.
  • The payment date should be included, if applicable.

Final Steps:

  • In section 7, it should be explained that why the refund was merited and the calculation methodology should be detailed.
  • If space is insufficient, extra pages for the explanation may be attached.
  • The form should be signed. In case of requesting abatement related to a jointly filed tax return, both spouses must sign.
  • A separate Form 843 should be filed for each period. For instance, if late filing fees were incurred in 2021 and 2022, two Form 843s should be submitted.

It should be noted that the reasonable cause and excess FICA tax refund contexts are of paramount importance:

  • Reasonable Cause: Demonstrating reasonable cause is vital when requesting abatements or refunds. Whether it is due to extraordinary circumstances or unavoidable mistakes; providing a compelling explanation significantly strengthens the case.
  • Excess FICA Tax Refund: Many individuals overlook excess FICA tax payments. If a taxpayer believes that these taxes were overpaid, Form 843 offers a pathway to reclaiming what is rightfully his/her/theirs.
