IRS Form 2848

Power of Attorney and Declaration of Representative

Form 2848 is the IRS power of attorney. It is what allows a tax attorney to step into your shoes with the IRS — answer the phone for you, attend audits, negotiate installment agreements and Offers in Compromise, file appeals, and receive your IRS correspondence. Without a properly filed 2848 on the CAF (Centralized Authorization File), the IRS will not discuss your case with anyone but you.

Who Files This

Any taxpayer who wants a licensed representative — attorney, CPA, or enrolled agent — to act for them before the IRS. Required for audit representation, collection appeals, Tax Court matters, OICs, installment agreements, lien releases, and penalty abatement requests handled by a third party.

What's at Stake With Form 2848

A defective or expired 2848 stops a representation engagement cold — the IRS refuses to talk to the rep, deadlines lapse, levies issue. Listing the wrong tax form, wrong year, or wrong type of tax (e.g., 1040 instead of 941) invalidates authority for everything else. A 2848 also gives the representative real power: they can sign closing agreements and consent to extend the statute of limitations.

How to File Form 2848 Correctly

  1. 1
    Identify the exact taxpayer

    Use the name on the original return and the correct SSN or EIN. For married couples, each spouse must file a separate 2848 — a joint 2848 is invalid.

  2. 2
    List every tax form and every year

    Be granular: 'Form 1040, 2019, 2020, 2021, 2022' and 'Form 941, all quarters 2021–2023.' Vague entries like 'all years' are rejected. Add Form 940, 1120, 1065, and any others involved.

  3. 3
    Enter the representative's CAF number and designation

    Attorneys check box 'a,' CPAs 'b,' enrolled agents 'c.' Each rep must sign Part II. Missing signatures invalidate the form.

  4. 4
    Decide what authority to grant and what to withhold

    By default the rep can do almost everything. Check the boxes that limit authority — most clients exclude 'sign returns' and 'substitute or add representatives.'

  5. 5
    File via the CAF unit (fax or online submission)

    Use Submit Forms 2848 and 8821 Online for fastest CAF posting. Faxing to the CAF unit usually posts within 5–10 business days; mail can take weeks. Always confirm CAF posting before assuming the rep has authority.

Why File Form 2848 With a Tax Attorney

Costly Mistakes With Form 2848

Listing 'all years' or 'all forms' — the IRS rejects vague scope and the rep gets locked out.

Forgetting to revoke prior POAs when switching tax counsel.

Filing a joint 2848 for a married couple instead of two separate forms.

Granting 'sign returns' authority without intending to.

Not confirming CAF posting before relying on the POA at an audit appointment.

Frequently Asked Questions About Form 2848

How long does a Form 2848 stay in effect?

Until you revoke it, the representative withdraws, or the taxpayer dies. Many clients revoke older 2848s when changing firms — otherwise old representatives still receive copies of your IRS notices.

What is the difference between Form 2848 and Form 8821?

Form 8821 only authorizes the IRS to share your tax information with a third party (read-only). Form 2848 also lets that party advocate, sign, and negotiate on your behalf. Audit and collection representation require 2848.

Can I have more than one Form 2848 on file?

Yes — you can authorize multiple representatives, and a new 2848 does not automatically revoke older ones unless you check the revocation box. This is a common mistake when switching firms.

Does Form 2848 cover state tax agencies?

No. Every state has its own POA form (e.g., California Form 3520, New York Form POA-1). A federal 2848 has no effect on state collections, audits, or appeals.
