IRS Form 8821 authorizes a designated person or organization to inspect or receive specified confidential tax information. It does not authorize that designee to represent you before the IRS.
Information access or representation?
Use Form 8821 when the intended task is access to the tax information identified in the authorization. The IRS allows individuals and organizations to be designated. If someone must advocate your tax position or otherwise represent you, compare Form 2848 and its eligibility requirements.
The form also warns that it is not a request for copies of tax returns. Match the authorization to the service you need instead of treating every IRS document as a power of attorney.
What to enter before signing
- Line 1: taxpayer identification and contact information.
- Line 2: designee information, including an attachment if you name more than two designees.
- Line 3: tax type, form number, years or periods, and any specific tax matters.
- Line 4: check the instructions for a specific use not recorded on CAF.
- Line 5: review treatment of previous information authorizations.
- Line 6: the taxpayer or authorized signer signs and dates the completed form.
Review entries before signing; the PDF specifically warns against signing a blank or incomplete authorization.

When the 120-day rule applies
The IRS instructions distinguish the purpose of the disclosure. When Form 8821 is submitted for a purpose other than addressing or resolving a tax matter with the IRS, such as a lender’s income verification, the IRS must receive it within 120 days of the taxpayer’s signature. That requirement does not apply to authorization submitted for assistance with an IRS tax matter.
Check the purpose and timing together before submitting a signed form that has been held for several months.

How to submit and handle signatures
The IRS provides online, mail and fax routes, with special handling for specific-use matters. Use the instructions for the right destination. Electronically signed forms must use the online route; mail or fax submissions require a handwritten signature under the IRS instructions.
The online service accepts one authorization at a time. Keep attachments with the relevant form in a single file and follow the current upload instructions. Do not send an online duplicate of a form already mailed or faxed. Submission happens on the IRS website, not in this directory.
Previous authorizations and notices
Line 5 addresses retention and revocation of earlier tax information authorizations. Review it before submitting a replacement; retaining an earlier authorization requires following the form’s checkbox and attachment instructions. Specific-use authorizations have separate handling.
Line 2 includes notice-and-communication choices. Decide whether copies should be sent, then verify names and contact details. An authorization to receive information does not become representation authority because a designee receives notices.
Common questions
Does the designee sign a representative declaration?
Form 8821 does not have the representative-declaration section found on Form 2848. Its taxpayer signature section is line 6.

Can a company receive my information?
The IRS permits organizations as well as individuals to be designated, subject to the information and scope entered on the form.

Is the 120-day limit required for every Form 8821?
No. The instructions apply that receipt deadline to disclosure for purposes other than addressing or resolving an IRS tax matter.
