IRS Form 8821: Tax Information Authorization Guide

IRS Form 8821, Tax Information Authorization, allows a taxpayer to designate an individual or organization to inspect and/or receive specified confidential tax information. It does not authorize the designee to represent the taxpayer before the IRS, advocate a position, sign most returns, or exercise the broader authority granted through Form 2848.

What Form 8821 Authorizes

The authorization can allow a named designee to receive or inspect confidential information for the tax types, forms, years, quarters, or other periods listed. Examples include allowing:

a lender to verify specified tax information;
a family member to receive information about a particular tax account;
a payroll or accounting service to inspect specified employment-tax information;
a tax professional to receive information without being appointed as the taxpayer’s representative.

The taxpayer controls the scope by accurately completing the tax-information table. The IRS will not infer unlimited access from a vague description.

What Form 8821 Does Not Authorize

A Form 8821 designee generally cannot:

represent the taxpayer in an examination, appeal, collection matter, or other IRS proceeding;
advocate or negotiate on the taxpayer’s behalf;
sign a tax return for the taxpayer;
substitute another representative;
receive refund checks;
access tax matters or periods not listed on the authorization.

If representation is needed, review Form 2848, Power of Attorney and Declaration of Representative.

How to Complete Form 8821

Line 1 — Taxpayer Information

Enter the taxpayer’s name, address, taxpayer identification number, and daytime telephone number. Businesses should use the entity name and EIN consistently with IRS records.

Line 2 — Appointee

List the designee’s name, address, telephone number, and fax number when applicable. A Centralized Authorization File number may be entered if one exists. The IRS instructions limit the number of designees who can receive copies of notices and communications, even when additional designees are listed on an attachment.

Line 3 — Tax Information

Specify each tax matter clearly:

type of tax information;
tax form number;
year, quarter, or period;
specific tax matter when needed.

Do not use general phrases such as “all years” or leave the scope ambiguous. The instructions restrict how future periods may be listed; use exact year or period formats.

Line 4 — Specific Use Not Recorded on the CAF

Check line 4 only for a specific-use authorization described in the instructions that should not be recorded on the Centralized Authorization File. Examples and consequences are explained in the official instructions.

Line 5 — Disclosure and Prior Authorizations

Follow the form carefully regarding disclosure to other parties and whether existing authorizations for the same matters remain in effect. Form 8821 can also be used to revoke or withdraw prior tax-information authorizations.

Line 6 — Taxpayer Signature

The taxpayer, corporate officer, partner, guardian, executor, trustee, or other authorized fiduciary signs in the appropriate capacity. The IRS can reject an unsigned form or a form signed by someone whose authority is not established.

How to Submit Form 8821?

Available submission routes depend on the taxpayer, designee, and IRS procedure:

Online upload: the IRS provides a secure option to submit Forms 2848 and 8821 online. Follow file, authentication, and attachment requirements.
Fax or mail: send the form to the appropriate CAF unit listed in the current instructions based on the taxpayer’s address and matter.
Specific-use submission: provide it to the IRS office handling the specific matter when line 4 and the instructions apply.

Do not email a completed form through ordinary email; it contains taxpayer identification and authorization information.

How Long Does Form 8821 Last?

The authorization covers only the listed matters and periods and remains subject to IRS rules, revocation, withdrawal, and any applicable expiration or retention limitations. An authorization does not automatically extend to a new tax type or period merely because the same designee continues helping the taxpayer.

How to Revoke an Authorization?

Taxpayers can revoke an authorization using the procedure in the current instructions, commonly by submitting a copy marked “REVOKE” with a current signature and date or by providing a statement containing the required identifying information. A designee who no longer wishes to act can withdraw under the separate instruction procedure.

Common Mistakes

Using Form 8821 when representation requires Form 2848.
Entering “all taxes” or “all years” instead of specific matters and periods.
Omitting a signature, title, or date.
Assuming the designee can sign returns or refund checks.
Sending the form to the wrong CAF unit.
Uploading Form 8821 and attachments as separate files when the IRS portal requires one combined file.
Downloading a recreated third-party form instead of the current IRS PDF.

Frequently Asked Questions

Is there a 2026 edition of Form 8821?

As of August 6, 2026, the IRS lists the January 2021 form and September 2021 instructions as current. Use the revision the IRS currently publishes.

Can a family member be a Form 8821 designee?

Yes. A designee does not have to be a tax professional, but access remains limited to the information and periods listed.

Does Form 8821 allow the designee to speak to the IRS?

A designee may receive or inspect authorized information verbally or in writing, but cannot represent or advocate for the taxpayer. The distinction depends on the nature of the interaction.

Can Form 8821 request a tax transcript?

It authorizes access but is not itself the standard transcript-request form. The authorized person may use applicable IRS transcript procedures; taxpayers can also use an IRS Online Account or a Form 4506-series request when appropriate.
