A client signs a form, and the IRS still refuses to talk to you. The paper you chose, and the boxes you left blank, decide whether you are a representative or a spectator.
A power of attorney is how a taxpayer puts someone else in their place before the Internal Revenue Service (IRS). The taxpayer appoints an eligible person, and that person can then act for the taxpayer on the specific tax matters the form lists. Form 2848, Power of Attorney and Declaration of Representative, is the IRS document that records that appointment.
Signing a power of attorney does three separate jobs at the same time:
- It shows the taxpayer agreed to let the IRS disclose return information to the representative.
- It lets the representative advocate for the taxpayer, which means arguing the case, negotiating and signing agreements.
- It records the representative's statement that they are eligible to practice under Circular 230, the Treasury rules for people who practice before the IRS.
Common mistakes
- Treating "all years" as a valid period. If you write "all years" or "all taxes" on line 3, the IRS rejects the form outright. List each year, or give a stated range of quarterly periods.
- Measuring the future-period cap from the fax date. The limit runs 3 years from December 31 of the year of receipt, not 3 years from the day the IRS gets the form. So a form received in 2026 reaches through 2029, not just to mid-2029.
- Assuming a POA lets you sign the return. The default grant never includes signing the return. You need the line 5a "Sign a return" box and the 26 CFR 1.6012-1(a)(5) statement naming one of the three reasons: disease or injury, a 60-day continuous absence, or specific IRS permission.
Bottom line
- Form 2848 grants representation plus disclosure and may name only individuals eligible to practice; Form 8821 grants disclosure only and may name anyone.
- Line 3 must state matter, form number, and specific periods; "all years" is rejected, and future periods reach only 3 years past December 31 of the year of receipt.
- The printed line 3 grant already covers signing consents to extend the assessment period, waivers, and section 7121 closing agreements.
- Line 5a adds acts (substitution, third-party disclosure, return signing); line 5b removes acts from the default grant.
Exam shortcut
Run one filter on every authorization stem: does this person need to talk, or only to read? Talk means 2848 and a Circular 230 practitioner. Read means 8821 and anyone. Then run the line ladder in order: 3 (what matter and period), 5a (what extra acts), 5b (what was carved out), 6 (who got fired). Most wrong answers hide in the line the stem quietly skipped.
