IRS Form 8821

Fax Form 8821 to the IRS

Find the CAF unit that records your tax information authorization, from the IRS’s own instructions, and send your form there.

What the office requires

  • Sign it by hand, in ink

    The IRS doesn’t accept a digital, electronic or typed signature on a form sent by fax. Print it, sign it, then add a scan or a photo of it.

  • Checked the box on line 4?

    Then don’t send Form 8821 to a CAF unit: the IRS asks for it at the office handling that matter. Use the fax number that office gives you. Send to that number

  • For something other than a tax matter?

    Such as a lender checking your income: the IRS must receive the form within 120 days of the day you sign it.
