Form 8821 and Form 2848 both give someone access to your IRS information, but they grant very different powers. Form 8821, the Tax Information Authorization, lets a person or organization you name inspect or receive your confidential tax information. It does not let them speak for you, argue your position or sign anything. Form 2848, the Power of Attorney and Declaration of Representative, lets an eligible individual represent you before the IRS, negotiate and sign on your behalf. If a preparer, lender or adviser asks you to sign one of these, the difference decides how much authority you are handing over.
Scope: based on the IRS instructions for Form 8821 and IRS authorization guidance as published in November 2026; the rules are not tied to a single tax year. California uses its own forms, covered below. TaxProsOfCA.com is not a tax firm and gives no tax advice.
Form 8821 in plain terms
The IRS Instructions for Form 8821 say the form authorizes “any individual, corporation, firm, organization, or partnership you designate to inspect and/or receive your confidential information verbally or in writing for the type of tax and the years or periods you list.” The same form is used to revoke earlier tax information authorizations.
The instructions are just as specific about the limits. Form 8821 does not authorize your designee:
- To speak on your behalf
- To advocate your position regarding federal tax laws
- To execute waivers, consents or closing agreements
- To represent you in any other manner before the IRS
- To authorize disclosure of your information to yet another third party, or to substitute someone else as designee
The instructions also state that a designee “is never allowed to endorse or negotiate a taxpayer’s refund check or receive a taxpayer’s refund via direct deposit.”
Form 2848 in plain terms
The IRS authorizations page says a power of attorney lets the person you name represent, advocate, negotiate and sign on your behalf, argue facts and the application of law, receive your tax information for the matters you specify, and receive copies of IRS notices if you choose. Your representative must be an individual eligible to practice before the IRS, which includes attorneys, CPAs and enrolled agents, and in special and limited circumstances unenrolled return preparers, family members, employees and students. The site’s full explainer on Form 2848 and tax power of attorney goes into the representation rules.
Side by side
| Form 8821 | Form 2848 | |
|---|---|---|

| See your information | Yes, for the matters and periods listed | Yes, for the matters and periods listed |
| Speak or argue for you | No | Yes |
| Sign agreements for you | No | Yes, within the authority granted |
| How long it lasts | Until revoked or withdrawn | Until revoked or withdrawn |
When Form 8821 is the right fit
The IRS lists several situations that call for a tax information authorization rather than representation:
- Income verification. The authorizations page gives the example of disclosure “for a purpose other than resolving a tax matter,” such as income verification required by a lender or a background check. Candidates who are asked to authorize release of tax information during hiring may find this guide to what employers check in references and background screening helpful context.
- A preparer pulling your records. A preparer who needs to see transcripts before preparing an overdue or amended return may ask for an 8821 because they only need to look, not to represent you. The site’s walkthrough of getting your IRS tax transcript shows the information they will see.
- Extending access past the designee checkbox. IRS Topic No. 254 points to Form 8821 to extend the authority to receive and inspect returns beyond the one-year Third Party Designee period.
When you need Form 2848 instead
If the IRS has opened an examination, a collection action or an appeal, and you want someone to deal with it for you, an 8821 will not do. IRS Topic No. 254 says only attorneys, CPAs and enrolled agents can represent taxpayers in all matters, including audits, collections and appeals, while preparers in the Annual Filing Season Program have limited rights for audits of returns they prepared and signed. The site’s guide to who can represent you in an IRS or FTB audit covers that ground.
Details on the 8821 worth reading before you sign
Line 2: copies of your notices
If you want the designee to receive copies of all IRS notices and communications, a box under their name must be checked. The instructions limit this to two designees for the same matters, and say not to check the box if you do not want copies going to them.
Line 3: third-party software
Your designee may not use an Intermediate Service Provider, a private company that retrieves and stores tax data, to pull your information unless you check the box on line 3. Without it, the designee must get your information directly through the IRS Transcript Delivery System.
Line 4: specific use
Authorizations for certain purposes, such as disclosure to loan companies or educational institutions or for background checks, are not recorded on the IRS Centralized Authorization File. These go on line 4 and are mailed or faxed to the IRS office handling the matter.
Line 5: older authorizations
Unless line 4 is checked, filing a new 8821 automatically revokes prior tax information authorizations on file, unless you attach a copy of any you want to keep and check line 5. If you have an existing arrangement with a different preparer, decide whether you want it to continue.
Revoking an 8821
To revoke one without filing a new one, the instructions say to write “REVOKE” across the top of the authorization, add a current signature and date under the original, and send it to the IRS. If you no longer have a copy, you can send a signed notice listing the designee, the matters and periods, or stating “revoke all years/periods.”
California uses different forms
Neither federal form gives anyone access at the California Franchise Tax Board. According to the FTB 3534 form, California’s Tax Information Authorization lets the FTB release limited information such as estimated payments, notices, account history or compliance status. To authorize someone to act for you before the FTB, the form directs individuals to FTB 3520-PIT, the Individual or Fiduciary Power of Attorney Declaration.
