About Form 8821
Who fills it in
Use Form 8821 to let a person or organization inspect or receive your confidential tax information for the tax types and years you list. It doesn’t let them speak for you or represent you.
Where it goes
Submit it online, or by fax or mail. If it is for one specific matter (the box on line 4), send it to the IRS office handling that matter.
When
When it is for something other than a tax matter with the IRS — income verification for a lender, for example — the IRS must receive it within 120 days of your signature.
Watch out for
- To have someone represent you before the IRS, use Form 2848 instead.
- A form signed with an electronic signature can only be submitted online.
