Representation before the IRS

Powers of Attorney and Representation

How a taxpayer authorizes someone to deal with the IRS: Form 2848 for representation, Form 8821 for information only, and the lighter tools of oral consent and the third-party designee. The note covers what each authorizes, who signs, signing deadlines, the CAF, revocation and withdrawal, durable powers and signing returns for a taxpayer. Most SEE items cite the Form 2848 instructions (Rev. 9-2021).

Must-know for the exam

Form 2848 appoints an eligible representative to act for the taxpayer; Form 8821 only lets a designee receive confidential information (Form 2848 and 8821 instructions (Rev. 9-2021)).
A 2848 never authorizes endorsing or negotiating a refund check; substituting representatives or signing returns needs a specific line 5a grant (Form 2848 instructions (Rev. 9-2021), Line 5a).
An agent may sign a return only for disease or injury, 60 days' continuous absence from the US before the due date, or IRS permission for good cause (Treas. Reg. 1.6012-1(a)(5)).
The CAF records future periods ending no later than 3 years after December 31 of the year the IRS receives the form (Form 2848 instructions (Rev. 9-2021), Line 3).
A newly recorded 2848 revokes earlier ones for the same matter unless line 6 is checked and copies attached; it never revokes a Form 8821 (Form 2848 instructions (Rev. 9-2021), Line 6).
If the taxpayer signs first, a representative of a domestic taxpayer must sign within 45 days (60 days for taxpayers abroad) (Form 2848 instructions (Rev. 9-2021), Line 7).
Taxpayers revoke by writing REVOKE across the top; representatives withdraw by writing WITHDRAW; both sign and date (Form 2848 instructions (Rev. 9-2021)).
Spouses on a joint return each file their own Form 2848, even with the same representative (Form 2848 instructions (Rev. 9-2021), Line 1).
A durable power of attorney is accepted if it contains the required information and a signed Form 2848 Part II is attached (26 CFR 601.503(b)).
Electronically signed 2848s must be submitted online; mailed or faxed forms need handwritten signatures (Form 2848 instructions (Rev. 9-2021), How To File).

Traps that cost marks

Treating an 8821 designee as a representative.
Assuming a power of attorney automatically authorizes signing returns.
Allowing representatives to handle refund checks.
Assuming a POA covers all future years indefinitely.
Thinking both representatives remain authorized by default.
Confusing the taxpayer's REVOKE with the representative's WITHDRAW.
Using one jointly signed Form 2848.
Assuming a firm colleague can step in without authority.

Why it matters on the exam

Part 3 Domain 2 covers representation, and the power of attorney is its foundation. Questions test which form fits a need, what a representative may and may not do, who signs for different taxpayers, and how authority ends. The Form 2848 instructions (Rev. 9-2021) and the Conference and Practice Requirements in 26 CFR 601.501-601.509 (Pub. 216) are the sources.

Form 2848 may name only individuals eligible to practice; Form 8821 may name any individual or organization.

Choosing the authorization

Tool	Who can be named	What it allows
Form 2848	Eligible practitioners (designations a-r)	Represent, receive information, sign consents and closing agreements; more only if granted on line 5a
Form 8821	Any person or organization	Receive and inspect information only; never receive refunds
Oral disclosure consent	A third party on the call	Discuss a specific issue; ends with the conversation
Third-party designee on the return	Anyone the taxpayer names	Discuss that return's processing until the next year's due date

Frequently asked questions

Can a representative cash a client's refund check under Form 2848?

No. A Form 2848 never authorizes a representative to endorse or otherwise negotiate a refund check. Source: Form 2848 instructions (Rev. 9-2021), Line 5a, checked 12 Oct 2026.

How many future years can a Form 2848 cover?

Future tax periods ending no later than 3 years after the IRS receives the form. Periods that have already ended can be listed without that limit. Source: Form 2848 instructions (Rev. 9-2021), Line 3.

Is a third-party designee the same as a representative?

No. The designee checkbox on a return lets the IRS discuss that return's processing with the designee, generally until the next year's return due date. It does not authorize representation. Source: 2025 Form 1040 instructions, Third Party Designee.
