To let someone else deal with the IRS about your tax refund, you file an IRS authorization form rather than writing an authorization letter for a tax refund. The IRS uses three tools for this: the Third Party Designee checkbox on your return for basic questions about a single filing, Form 8821 to let someone view your tax information, and Form 2848 to give a representative power of attorney to act on your behalf. One limit applies to all three, and it surprises people: even with a full power of attorney, your representative cannot endorse your refund check or have the refund deposited into their account.
Which Form Matches What You Need Done
Pick the form by what you want the other person to actually do.
Third Party Designee
The Third Party Designee section is built into your tax return. Fill in a name, phone number, and a five-digit PIN, and you authorize the IRS to discuss that specific return and tax year with that person. The designee can call the IRS about your return’s processing status, answer IRS questions about the return, and request adjustments. The authorization expires one year from the due date of the return.
This is the right choice when you just want a family member or preparer to call and check on a refund from one specific filing.
Form 8821, Tax Information Authorization
Form 8821 appoints an individual or organization to inspect or receive your confidential tax information for the tax types and periods you list. The appointee can view transcripts, receive copies of notices, and see account details. They cannot represent you, sign anything, or make decisions. Use this when you want someone to monitor your account without giving them authority to act on it.
Form 2848, Power of Attorney
Form 2848 is the broadest of the three. It lets your representative inspect your confidential tax information and perform most acts you could perform yourself, including signing agreements, consents, and other documents tied to the tax matters listed on the form. If your refund is stuck in an audit, a payment plan negotiation, or a dispute where someone needs to actively push things forward with the IRS, this is the form you want.
What Authorization Cannot Do With the Refund Itself
No IRS authorization form lets a third party take possession of your refund. Line 5b of Form 2848 contains preprinted language stating that your representative is not authorized to endorse or negotiate any government-issued check related to your federal tax liability. This restriction cannot be overridden.
The direct deposit rules run the same direction. Refunds should only be deposited into U.S. bank accounts in the taxpayer’s name, the spouse’s name, or a joint account. No more than three electronic refunds can go to a single account or prepaid debit card in a year; over that limit, the IRS sends a paper check. A power of attorney does not create an exception. Your representative can call the IRS about your refund, track its status, and resolve issues delaying it, but the money has to flow to you.
If a paper check arrives, you endorse it yourself. Banks are often reluctant to cash third-party government checks even with a valid power of attorney, so if mobility or travel is an issue, plan around that before the check is issued.
Who Can Be Named as Your Representative
Treasury Department Circular 230 limits full representation rights to attorneys, certified public accountants, enrolled agents, enrolled actuaries, and enrolled retirement plan agents. Any of them can represent you on any tax matter before any IRS office.
Immediate family members can represent you under limited circumstances without professional credentials, but they must present satisfactory identification and proof of authority. Regular full-time employees can represent their employers, and officers can represent their organizations. The IRS calls this “limited practice,” and the authority is narrower than what a credentialed professional holds.
For a Form 8821 designation, the appointee does not need to be a credentialed practitioner at all, since they are only receiving information, not representing you.
Information to Gather Before You Fill Out the Form
- Full legal names for both the taxpayer and the representative, exactly as they appear on government-issued identification.
- The taxpayer’s Social Security Number or Individual Taxpayer Identification Number, which has to match IRS records.
- For Form 2848, the representative’s Centralized Authorization File (CAF) number if they have one, or “NONE” so the IRS assigns one. Depending on the representative’s designation, a PTIN, bar number, or enrollment card number is also required.
- Current mailing addresses for both parties.
- The specific tax matter: type of tax (income, employment, estate), the form number (such as 1040), and the exact year or period.
Vague descriptions get forms rejected. “Income tax, Form 1040, 2025” works. “All taxes” or a blank year will come back.
Completing Form 2848 Without Getting It Rejected
Lines 1 and 2 cover the taxpayer’s and representative’s identifying information. Line 3 is where you specify the tax matters: type of tax, form number, and years or periods. Line 4 lists specific additions or deletions to the representative’s authority.
Line 5a deserves close attention. The default power of attorney already covers signing agreements, receiving confidential information, and performing most acts you could do yourself. Certain acts require you to check a box on line 5a and add details: authorizing the representative to sign your tax return (only permitted if you have a disease or injury, have been outside the United States for at least 60 days before the filing deadline, or have received specific IRS permission), substituting or adding another representative, and authorizing disclosure of your return information to a third party.
Line 5b, again, is the restriction on endorsing or negotiating your refund check. It is preprinted and cannot be removed.
The taxpayer signs and dates line 7. If someone other than the taxpayer signs, the IRS requires documentation of that person’s authority, such as a court order or corporate resolution. On a joint return, both spouses must sign if both are granting the authorization.
Refunds for a Deceased Taxpayer
The rules change when the taxpayer has died, and Form 2848 is not what handles it.
A surviving spouse filing an original or amended joint return with the decedent can claim the refund without any extra authorization form. The surviving spouse signs the return and writes “filing as surviving spouse” in the signature area.
Most other claimants file Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer. The form has three categories:
- Line A: a surviving spouse who needs a refund check that was issued in both names reissued.
- Line B: a court-appointed personal representative filing Form 1040-X or Form 843, who must attach a copy of the court certificate showing the appointment, even if the certificate was previously filed with the IRS.
- Line C: anyone else claiming the refund on behalf of the estate.
A personal representative filing an original return (Form 1040, 1040-SR, 1040-NR, or 1040-SS) does not need Form 1310 if the court certificate is attached to the return. Original return with certificate attached, no extra form; amended return, Form 1310 plus the certificate.
How to Submit the Form
Three routes, with real speed differences.
The fastest is the IRS Tax Pro Account, an all-digital tool that processes power of attorney and tax information authorizations in real time without paper forms. When a credentialed tax professional initiates the request through Tax Pro Account, the authorization records to the Centralized Authorization File almost immediately. It currently works only for individual taxpayer authorizations, not business entities.
The second route is the IRS online upload tool at IRS.gov, where completed Forms 2848 and 8821 can be securely submitted. Uploaded forms are still processed manually on a first-in, first-out basis alongside faxed and mailed requests, so this is not real-time.
The third route is fax or mail to the appropriate CAF unit, which the IRS assigns geographically.
For fax, mail, and online upload, processing times have historically ranged from a few weeks to over two months during backlogs. Once the CAF is updated, the representative can see the taxpayer’s account in their professional tax software or the IRS online tools, and both parties may receive a confirmation notice.
Revoking the Authorization
You can revoke a power of attorney at any time. Write “REVOKE” across the top of the first page of the Form 2848, add a current signature and date, and fax or mail it to the appropriate CAF unit. If you do not have a copy of the original form, send a signed statement listing the representative’s name and address, the tax matters and periods covered, and a clear statement that the authority is revoked. “Revoke all years/periods” covers everything at once.
Representatives who want to stop acting for you follow the same process, writing “WITHDRAW” across the top of the form with their signature and date, then submitting it to the IRS.
Revoking Form 8821 works the same way. One detail to know: when you file a new Form 8821 without checking the box on line 5, the IRS automatically revokes all prior tax information authorizations on file. To keep an earlier authorization active while adding a new one, attach a copy of the one you want to retain and check line 5.
