Form 843: What It Is and When Should You Use It?

Form 843, Claim for Refund and Request for Abatement, is your official route to ask the IRS for (a) a refund of certain taxes or (b) an abatement (reduction or removal) of penalties, interest, fees, or additions to tax—but with important boundaries.

Form 843: Key Takeaways

  • Purpose – Use Form 843 to request a refund or abatement of certain IRS-assessed penalties, interest, fees, or specific non-income taxes.
  • Eligibility Matters – It’s only for specific situations (e.g., IRS errors, reasonable cause penalties, excess Social Security tax from one employer).
  • Strong Documentation – A clear written explanation and supporting evidence greatly improve approval chances.
  • Deadlines Apply – File within 2 years of payment or 3 years from return filing, whichever is later, and mail to the correct IRS address.

When to File for IRS Form 843

You’d reach for Form 843 when:

  • The IRS slapped you with interest or penalty by mistake.
  • You paid a branded prescription drug fee or an annual health insurance provider fee, and you’re in the clear to request a refund
  • You’re an employee who’s had excess Social Security, Medicare, or RRTA tax withheld by one employer, and that employer can’t (or won’t) fix the overcollection
  • You’re facing fees or penalties tied to incorrect IRS advice, dyed fuel misuse, misstatements due to appraisals, or trust fund recovery—basically a list of very specific exemptions.

Don’t use Form 843 to fix an ordinary income tax return or to ask for a refile of FICA. That’s handled with other forms like Form 941‑X, etc.

Overview: Your Step-by-Step Journey to Filling Form 843

  1. Confirm eligibility: Does your situation match one of the acceptable reasons above?
  2. Gather your documentation:
    • IRS notice (if one was issued), including section numbers for penalties you’re challenging.
    • Records of payment or assessed penalties.
    • Any supporting evidence: correspondences, receipts, medical records, legal advice or specific IRS guidance.
  3. Fill in the form:
    • Personal and taxpayer details.
    • Clearly check the box that matches your reason for filing.
    • Craft a persuasive statement and attach documents.
  4. Sign and date properly:
    • Joint filers must both sign.
    • Corporations require an officer’s signature and title.
    • Estates or trusts use a fiduciary signature.
  5. Submit it:
    • Mail to the address specified on any IRS notice you received.
    • If it's a branded drug fee, send it to the designated IRS address in Ogden, UT.
  6. Keep track of timing:
    • File within two years from payment of tax or three years from filing the return, whichever is later.
  7. After filing:
    • If the IRS denies your claim or doesn’t respond within six months, you can file a suit in U.S. District Court or U.S. Court of Federal Claims.

Form 843 Structure: Section-by-Section Breakdown

Let’s walk through the structure of Form 843—you’ll want to navigate with confidence and clarity.

Header: Boxes for Your Reason

Start strong—select the box that best explains your reason:

  • Abatement/refund of non-income tax (excluding FICA, RRTA).
  • Employee refund of excess Social Security, Medicare, or RRTA tax.
  • Penalty abatement due to reasonable cause or IRS error.
  • Specialty categories like dyed fuel misuse, branded prescription drug fee, or fees for health insurance providers.

1–3: Identification

  • Line 1–3: Name, address, and taxpayer identification number (SSN or EIN depending on entity).

4: Penalty Section Number (if applicable)

  • For penalty abatement, write the Internal Revenue Code section number of the penalty you're contesting (e.g., 6676, 6672

5a: Type of Request

  • Tick the category (abatement, refund, interest, fee, etc.) that aligns with your situation.

6: Tax Period

  • Identify the tax year or period relevant to your claim.

7: Explanation of Facts

  • This is your stage. Write a detailed, factual narrative—explain exactly what happened, why it was erroneous or unfair, and what relief you’re seeking.
  • Provide documentation such as IRS notices, timelines, third-party statements, or rationale (e.g., illness, reliance on incorrect advice).
  • Be concise, yet vivid and clear in describing your cause.

Attachments

Include any relevant files, labeled and referenced in your explanation. Whether it’s a damaged receipt, a physician’s note, or a corrected affidavit—label clearly.

Signature Section

  • Individuals/joint filers: Both spouses sign.
  • Corporations: Must include officer title.
  • Estates/Trusts: Fiduciary signature required.

Tips For Making Your Form 843 Submission Shine

  • Match precision: State “Reasonable cause: [insert explanation]” and back it up with proof—doctor’s notes, weather delays, death certificates, legal counsel, or correspondence.
  • Label everything: For complex cases, use 'Attachment A – IRS Notice dated MM/DD/YYYY' and reference it in your narrative.
  • Stay within limits: Don't overexpand—let your core story shine. If possible, keep your statement to one or two well-crafted pages.
  • Deadline savviness: If you're close to the limitation period but still building evidence, file a protective claim to preserve your right while gathering proofs.
  • Follow‑up: Mark your calendar—if no reply in six months, you may escalate to court.

Filing Addresses & Logistics

  • Use IRS notice instructions first: If you’ve received a notice, it usually tells you where to send your reply.
  • Typical special case: For branded prescription drug fee refunds, mail to:

Internal Revenue Service
Mail Stop 4921 BPDF
1973 N. Rulon White Blvd.
Ogden, UT 84404

  • Track your submission: Send via certified mail or priority post, keep copies and tracking info.

What to Expect Next

  1. Acknowledge receipt: The IRS may send a confirmation.
  2. Processing: Typically up to 6 months—during which they may ask for more information.
  3. Approval or denial: If accepted, you get a refund or abatement. If denied, you’re entitled to petition the courts.

Form 843 Guide FAQs

No, Form 843 must be filed by mail. The IRS does not currently offer an e-file option for this form, so you’ll need to print, sign, and send it to the correct address listed in the instructions or on your IRS notice.

You should only include copies, not originals, of any supporting documents. Keep your originals in a safe place in case the IRS requests to see them later.

Processing can take several months, often up to six months or more. If the IRS needs more information, they will contact you, which can extend the timeline.

Yes, but you must clearly list each tax period and explain your request for each one in your statement. In complex cases, the IRS recommends filing separate forms to avoid delays.

If the IRS denies your claim, you’ll receive a notice explaining why. You can appeal through the IRS Appeals Office or file a claim in U.S. District Court or the U.S. Court of Federal Claims.
