No, Form 843 cannot be faxed to the IRS. The agency does not accept this form by fax, email, or electronic filing of any kind. A signed paper copy has to arrive by mail, and the correct mailing address depends on why you’re filing. If you’re asking because you want penalty relief and a deadline is closing in, there’s a faster route worth checking before you print anything: many first-time penalty abatement requests can be handled over the phone.
Why Fax Isn’t an Option
The IRS requires a wet signature on Form 843 and expects supporting documents attached to the form itself.1Internal Revenue Service. Where to File for Form 843 There is no published fax number, no upload portal, and no email intake for this form. That makes submission slower than most taxpayers expect, and it makes getting the address right important. A form sent to the wrong service center can sit unrouted for months.
Where to Mail Form 843
The address you use depends on what your claim is about:
- If you’re responding to an IRS notice, mail Form 843 to the address printed on that notice.1Internal Revenue Service. Where to File for Form 843
- For an estate or gift tax refund tied to Form 706 or 709, send it to: Internal Revenue Service Center, Attn: E&G, Stop 824G, 7940 Kentucky Drive, Florence, KY 41042-2915.1Internal Revenue Service. Where to File for Form 843
- For penalty relief or any other claim not tied to a notice, mail it to the IRS service center where you would file a current-year return for the tax type your claim involves. The return instructions list that address.1Internal Revenue Service. Where to File for Form 843
- For a net interest rate of zero request, mail it to the service center where you filed your most recent return.1Internal Revenue Service. Where to File for Form 843
Form 843 doesn’t cover income tax refunds; those go on Form 1040-X. It also can’t be used for employer FICA or RRTA refund claims or for fuel-related excise tax refunds.2Internal Revenue Service. Form 843 – Claim for Refund and Request for Abatement
Protect Yourself When You Mail It
Use certified mail with return receipt requested. The IRS does not send its own confirmation that Form 843 arrived, so your postmark and delivery receipt are the only proof you have that the claim was filed and filed on time.
Timing matters because Form 843 is subject to a statute of limitations. If you filed a return for the period at issue, your claim must arrive within three years from the date you filed or two years from the date you paid the tax, whichever is later.3Internal Revenue Service. Time You Can Claim a Credit or Refund If you never filed a return for that period, you have two years from the date the tax was paid.4eCFR. 26 CFR 301.6511(a)-1 – Period of Limitation on Filing Claim Miss the window and the IRS will deny the claim without reaching its merits.
Since fax isn’t available, you can’t transmit at the eleventh hour. Build in at least a week of mail time before the deadline runs out.
The Phone Shortcut Most People Miss
Before you mail Form 843 for a penalty, check whether you qualify for the First-Time Abate program. This administrative waiver can remove a failure-to-file, failure-to-pay, or failure-to-deposit penalty without any reasonable cause showing at all.5Internal Revenue Service. 20.1.1 Introduction and Penalty Relief
Three conditions have to be met: you filed the same type of return for the three tax years before the penalized year, none of those prior-year returns carried unreversed penalties (other than estimated tax penalties), and you’re current on all required filings or have a valid extension in place.5Internal Revenue Service. 20.1.1 Introduction and Penalty Relief The waiver applies to one tax period and doesn’t cover every penalty type; estimated tax penalties, daily delinquency penalties, and penalties on event-based filings are excluded.
To request it, call the toll-free number on your IRS notice. The representative reviews your account during the call and tells you on the spot whether the penalty is removed. You don’t need to name the program or send documents. If the phone request is denied, you can still follow up with a written statement or Form 843.6Internal Revenue Service. Administrative Penalty Relief For many taxpayers with a clean history, one phone call replaces the entire mailing exercise.
