Form 2848 Instructions: IRS Power of Attorney Walkthrough (2025)
The short answer: these Form 2848 instructions cover the IRS Power of Attorney and Declaration of Representative. You use Form 2848 to authorize an eligible person — an enrolled agent, CPA, or attorney — to talk to the IRS for you on specific tax matters and years. Name the right person, list the exact years, and both of you sign.
⏱ Timing tip: a signed Form 2848 must reach the IRS before your representative can act for you. Faxed or online submissions usually post to your account within about 5 business days; mailed forms can take several weeks. If a deadline is near, fax it or use the online tool — don't mail it.
What Form 2848 is — and what it isn't
Form 2848 is the IRS Power of Attorney (often shortened to "POA"). It lets the person you name step into your shoes for dealing with the IRS: they can call agents, receive copies of your notices, pull your transcripts, and argue your case on the tax matters and years you list. The IRS's own page is the About Form 2848 guide.
Here's what it does not do. It does not let your representative sign your tax return, cash your refund check, or spend your money — those powers only exist if you specifically grant them in writing on the form. It also is not a general, all-of-life power of attorney like the kind you'd sign at an estate planner's office. Form 2848 only covers the IRS, and only the matters you spell out.
Why people file Form 2848
Most people reach for Form 2848 when the IRS contact gets serious and they want someone who knows the system to handle it. Common reasons include:
- An audit or examination you'd rather not face alone.
- A collection case — payment plans, an Offer in Compromise, or a levy you need stopped.
- Helping a parent or relative who can no longer manage their own tax affairs. (See our separate guide on using power of attorney for a parent's IRS matters.)
- Letting a representative call the IRS, get transcripts, and confirm exactly what's owed before you make any decisions.
If you only want someone to see your tax information but not speak for you, Form 8821 (Tax Information Authorization) is the lighter-weight choice. Form 2848 is for representation.
Who you can name as your representative
This trips people up, so read carefully: not just anyone can represent you before the IRS. The form's Part II — the Declaration of Representative — has to be signed by someone in an eligible category. The main ones are:
- Enrolled agents (EAs) — federally authorized tax practitioners. Curious what that means? See our explainer on what an enrolled agent is.
- Certified public accountants (CPAs).
- Attorneys.
- A few limited categories, such as enrolled actuaries and certain family members in narrow situations.
A friend, neighbor, or adult child generally cannot be your Form 2848 representative just because you trust them. If that's your situation, Form 8821 may be the right path instead.
Form 2848 instructions, line by line
The form is two pages. Don't let it intimidate you — here's what each part asks for.
- Line 1 — Taxpayer information. Your name, address, and taxpayer identification number, plus a daytime phone. Use the name and number exactly as they appear on the returns in question.
- Line 2 — Representative(s). The name, address, and contact details of each person you're authorizing. Each representative also needs their CAF number and PTIN entered here. (You don't need to know what those are — your representative provides them.)
- Line 3 — Acts authorized. The heart of the form. Describe the matter (for example, "Income Tax, Form 1040") and the specific years or periods (for example, "2021, 2022, 2023"). Be exact — a representative cannot act on a year you didn't list.
- Line 4 — Specific use not recorded on the CAF. Only check this for one-off matters the IRS doesn't keep on file. Most people leave it blank.
- Line 5a / 5b — Additional acts and restrictions. Here you grant or limit narrow powers, such as authorizing someone to substitute another representative, or restricting what they can do.
- Line 6 — Retention of prior authorizations. Filing a new 2848 normally cancels earlier ones for the same matters. Check this box if you want an old authorization to stay in place too.
- Line 7 — Taxpayer signature. You sign and date. If it's a joint return and you both want representation, each spouse must file a separate Form 2848.
- Part II — Declaration of Representative. Your representative signs, lists their designation (the letter code for EA, CPA, attorney, etc.), and the state or licensing detail. Without this signature, the form is incomplete.
The single most common mistake is on Line 3: leaving out a year or being too vague. If the IRS later assesses a year you didn't list, your representative is locked out until you file an updated form.
How to file Form 2848, step by step
- Fill it out completely — both your signature and your representative's signature must be on it.
- Pick a submission method: fax or mail to the IRS CAF unit for your area (the addresses and fax numbers are in the official Instructions for Form 2848), use the IRS "Submit Forms 2848 and 8821 Online" tool, or have your representative upload it through their IRS Tax Pro Account.
- Choose speed when a deadline is near. Fax and online submissions generally process in about a week; mail can take several weeks.
- Confirm it posted. Your representative can check the IRS Centralized Authorization File (CAF) to confirm the authorization is active before they call on your behalf.
- Keep a copy. Save the signed form and any fax confirmation. You'll need it if you ever revoke the authorization.

Form 2848 questions, answered
What does Form 2848 actually let someone do?
Form 2848 lets the person you name represent you before the IRS — talk to agents, receive your notices, get your transcripts, and argue your case on the specific tax matters and years you list. It does not let them sign your tax return or spend your money unless you grant those narrow powers in writing.
Who can I name on Form 2848?
Only certain people can represent you before the IRS: enrolled agents, CPAs, and attorneys are the main ones, plus a few limited categories like enrolled actuaries. A friend or family member generally cannot be your representative on Form 2848. If you only want someone to receive your information, Form 8821 may be the better fit.
How long does Form 2848 stay in effect?
A Form 2848 stays active until you revoke it, your representative withdraws, or you file a newer Form 2848 that replaces it for the same matters. It does not expire on its own. To end it, write "REVOKE" across a copy, sign and date it, and mail or fax it to the IRS.
How do I file Form 2848 with the IRS?
You can mail or fax the signed form to the IRS CAF unit for your area, submit it online through the IRS "Submit Forms 2848 and 8821 Online" tool, or your representative can upload it through their Tax Pro Account. Fax and online submissions usually process faster than mail.
What's the difference between Form 2848 and Form 8821?
Form 2848 grants representation — the person can speak and act for you before the IRS. Form 8821 only grants access to your tax information; it does not let anyone argue your case. Choose 2848 when you need someone to handle a dispute, audit, or collection matter on your behalf.
