Form 8821: Designee Access, Filing, and Revocation

IRS Form 8821, the Tax Information Authorization, lets you give someone permission to view and receive your confidential federal tax records for the tax types and years you list, without granting them any power to act on your behalf. It’s the standard tool when an accountant, financial advisor, family member, or lender needs access to your IRS account information. Because the authorization is view-only, filing it is simpler and carries less risk than a full power of attorney.¹

What Form 8821 Lets Your Designee Do

Once the IRS processes the form, your designee can inspect and receive your confidential tax information, verbally or in writing, for the specific tax types and periods you listed.¹ In practice, that means pulling tax transcripts, reviewing an account balance, calling the IRS with questions about a return, and receiving copies of any notices the IRS sends you.

The form does not let your designee speak on your behalf, advocate a legal position, sign anything, negotiate a payment plan, agree to extend a deadline, or represent you in an audit or appeal.² A designee also cannot share your tax information with another third party, substitute someone else as the authorized person, endorse your refund check, or receive a refund by direct deposit.³ If any of those actions are needed, you need a different form.

Form 8821 or Form 2848 — Which One You Actually Need

The clearest way to see what Form 8821 is for is to put it next to Form 2848, Power of Attorney and Declaration of Representative. Form 8821 is view-only access. Form 2848 is authority to act: a representative under 2848 can sign documents, negotiate settlements, appear at an audit, and make binding agreements with the IRS on your behalf.⁴

That expanded authority narrows who qualifies. Form 2848 requires the representative to be someone eligible to practice before the IRS, such as an attorney, CPA, or enrolled agent. Form 8821 has no such requirement. You can name a family member, a bookkeeper, a mortgage broker — anyone — because they’re only receiving information.³ Use Form 8821 when someone needs to see your tax records. Use Form 2848 when someone needs to handle your tax matters.

How to Fill Out Form 8821

The form is short, but the IRS rejects a surprising number of submissions over avoidable errors. Work through it line by line.

Line 1: Your Information

Enter your full legal name, current mailing address, and Taxpayer Identification Number. For individuals that’s your Social Security number; for businesses, your Employer Identification Number. If you file jointly and both spouses want to authorize the same designee, only one Form 8821 is needed, but both names and TINs should appear.²

Line 2: Your Designee

Provide the designee’s name, mailing address, and Centralized Authorization File (CAF) number if they have one. Tax professionals who regularly deal with the IRS usually already have one. If your designee doesn’t, leave the field blank and the IRS will assign one when the form is processed. Line 2 also includes a checkbox to have the IRS send copies of your notices and correspondence directly to the designee. Check it if you want your tax professional to see what you see.¹

Line 3: Tax Matters

This is where most mistakes happen. List the specific type of tax, the form number, and the exact years or periods covered. For example: “Income — 1040 — 2023, 2024, 2025.” For a range, write “2023 thru 2025.” For quarterly periods, write something like “2nd 2024–4th 2024.”²

Two rules trip people up. Never use vague references like “All years,” “All periods,” or “All taxes”; the IRS will reject the form outright.⁵ And you can list future tax years, but the IRS will not record any future period that exceeds three years from December 31 of the year it receives the form.² File in 2026 and list 2030, and that period won’t make it into the system.

Line 5: Signature and Date

Sign and date the form. Paper and fax submissions require a handwritten signature. If you submit through the IRS Tax Pro Account, an electronic signature is accepted. The date matters. When the form is being used for a non-tax purpose, such as income verification for a mortgage, the IRS must receive it within 120 days of your signature date. That deadline does not apply when you’re authorizing disclosure to help with an actual tax matter.³

Where to Send It

You have three ways to submit: mail, fax, or the IRS Tax Pro Account online. The correct mailing address and fax number depend on where you live.²

Eastern states (AL through WV, including DC): Internal Revenue Service, 5333 Getwell Road, Stop 8423, Memphis, TN 38118. Fax: 855-214-7519.
Western states (AK through WY): Internal Revenue Service, 1973 Rulon White Blvd., MS 6737, Ogden, UT 84201. Fax: 855-214-7522.
International, U.S. territories, and APO/FPO addresses: Internal Revenue Service, International CAF Team, 2970 Market Street, MS 4-H14.123, Philadelphia, PA 19104. Fax: 855-772-3156, or 304-707-9785 from outside the U.S.

Fax numbers can change without notice, so confirm at irs.gov/Form8821 before sending.

The fastest option is the IRS Tax Pro Account, which processes individual tax information authorizations in real time.⁶ Paper and fax submissions typically take several weeks before the authorization shows up in the IRS system.

Why the IRS Rejects Forms

The IRS returns forms unprocessed for a small number of recurring reasons.⁵ Check three things before you send:

A current signature with a date next to it. A missing signature or missing date is an automatic rejection.
Specific tax periods on Line 3. No “All years” or “All future periods.”
The right Taxpayer Identification Number. A wrong SSN or EIN means the IRS can’t match the form to your account.

Fixing a rejected form and resubmitting adds weeks to an already slow process if you’re going through the mail or by fax.

How Long Form 8821 Stays in Effect

The authorization stays active until the expiration date you write on the form. If you leave that field blank, it has no built-in end date and remains in effect until you revoke it or file a replacement. The three-year cap on future periods still applies, so a form filed in 2026 won’t cover 2030 and beyond even without an expiration date.²

Filing a new Form 8821 for the same tax matters and periods automatically revokes all previous authorizations for those matters unless you attach copies of the prior forms to the new submission. Forgetting to attach those copies is an easy way to accidentally cut off someone else’s access.²

How to Revoke Form 8821

You can revoke the authorization at any time. The simplest method: take a copy of the original form, write “REVOKE” across the top, sign and date it below your original signature, and send it to the IRS office that matches your state from the addresses above.³

If you don’t have a copy, send a written notification to the same address. State that you’re revoking the designee’s authority, list the designee’s name and address, and identify the tax matters and periods being revoked. To revoke everything, write “revoke all years/periods” rather than listing each one. Sign and date it.³ Your designee can also withdraw on their own by submitting a similar written request, so you don’t have to be the one to end it.

Using Form 8821 for a Mortgage or Income Verification

Form 8821 isn’t limited to tax problems. Mortgage lenders, landlords, and background-check companies routinely ask applicants to file one so they can verify income directly with the IRS.⁷ When the form is used for a non-tax purpose like this, the 120-day rule kicks in: the IRS must receive the form within 120 days of the signature date, or it will be rejected. That deadline does not apply when the form is filed to help with an actual tax matter.³

If a lender hands you a Form 8821 during a loan application, sign it as close to the submission date as you can so you don’t run up against that window.
