From the IRS instructions for Forms 2848 and 8821 (irs.gov/instructions/i2848, last reviewed April 30, 2026), checked October 10, 2026. The IRS says the numbers may change without notice, so check the instructions before you send.

Signatures the IRS accepts by fax

The IRS says you must handwrite your signature on Form 2848 or 8821 if you file it by fax or mail. Digital, electronic or typed signatures are valid only when the form is submitted online.

On Form 2848 the taxpayer and the representative both sign and date; the representative generally signs within 45 days of the taxpayer’s signature, or 60 days for a taxpayer living abroad. A business signer adds their exact title, and spouses on a joint return each file their own form. Form 8821 needs the taxpayer’s signature and date.

So print the form, sign it in ink and scan or photograph the signed pages. A signature image pasted into a PDF counts as an electronic signature, which the IRS takes online only.

Mistakes that get a form sent back

The IRS lists these as common reasons it rejects a power of attorney or an authorization:

  • A missing signature or date, from the taxpayer or the representative.
  • Tax periods that aren’t specific, like “all years” or “all future periods”.
  • Line 6 of Form 2848 checked without a copy of the earlier power of attorney attached.
  • A missing designation, jurisdiction, or bar, license or enrollment number on Form 2848.
  • A business signer’s title left out.
  • A wrong SSN or EIN on Form 8821.

Also check the box on line 6 of Form 2848, or line 5 of Form 8821, if you want to keep earlier authorizations: left unchecked, the new form revokes them.

After you send it

The IRS works through faxed forms in the order they arrive and doesn’t tell you when yours is done; its Form 2848 and 8821 processing status page gives the current wait. Keep the FaxJet receipt and its tracking link.

These forms carry Social Security numbers. FaxJet keeps your document until you delete it, so once the receipt shows the fax was delivered, delete it from the tracking page. To write a cover page, use the free fax cover sheet maker.

Questions

Which fax number is mine, Memphis or Ogden?

It goes by the state the taxpayer lives in. Eastern states, plus Arkansas and Louisiana, go to Memphis; western states, plus Wisconsin, go to Ogden. The table on this page lists every state.

Can I fax a form I signed electronically?

No. The IRS takes forms with electronic, typed or image signatures only through its online submission (IRS.gov/Submit2848 or IRS.gov/Submit8821). A faxed or mailed form must be signed in ink.

Will the IRS confirm that it got my fax?

No. The IRS processes forms in the order it receives them and doesn’t notify you. A tax professional can see recorded authorizations in Tax Pro Account. Keep your fax receipt as proof of sending.

Does the IRS accept faxes from online fax services?

The instructions for Forms 2848 and 8821 don’t mention them. The IRS’s notice pages name online fax services as a way to reply and ask you to read the service’s privacy and security policies. FaxJet delivers to the IRS fax machine like any other fax.

What if I checked the box on line 4?

Then don’t use these numbers. A form for a specific use the IRS won’t record goes to the IRS office handling that matter.

Can these numbers change?

Yes, the IRS says they may change without notice. The numbers here come from the IRS instructions last reviewed on April 30, 2026, checked on October 10, 2026.
