Tax Power of Attorney: What Form 2848 Does and How to File It

A tax power of attorney is a written authorization that lets someone you choose represent you before the IRS, and you create one by filing IRS Form 2848. Once the IRS processes the form, your representative can argue your case in an audit, negotiate an installment plan, respond to collection notices, sign certain agreements, and receive copies of the IRS correspondence sent to you. The authority is narrow by design: it covers only the federal tax matters and years you list, not healthcare, property, or anything else a general power of attorney might reach.

What Your Representative Can Do for You

Once Form 2848 is on file, your representative steps into your shoes for the tax matters you listed. That person can receive and inspect your confidential tax information, respond to IRS inquiries, attend meetings with revenue agents or officers without you present, and handle correspondence on your behalf.¹ The representative can also execute waivers that extend the time the IRS has to assess or collect a tax, and can sign closing agreements under 26 U.S.C. § 7121 that permanently settle your liability for a given period. Once approved, a closing agreement can only be reopened for fraud or misrepresentation of a material fact.²

Some acts require an extra step. Signing a tax return on your behalf is only allowed when you’re physically unable to sign due to disease or injury, you’ve been outside the United States for at least 60 days before the filing deadline, or the IRS grants specific permission for other good cause. To authorize return-signing, you check the appropriate box on Line 5a.³ Line 5a is also where you can let the representative substitute or add another representative, consent to disclosing your return information to a third party, or access records through an IRS-approved intermediary service provider.

One limit is absolute: no representative can endorse or negotiate a government check issued for your refund or any other payment. The form cannot override that restriction.³

Who Can Serve as Your Representative

Not just anyone can act for you at the IRS. Treasury Department Circular 230 restricts representation to specific categories of practitioners.⁴ Three groups have unlimited practice rights:

Attorneys in good standing with the highest court of any state, territory, or the District of Columbia.
Certified Public Accountants holding an active license from a state board of accountancy.
Enrolled agents, who either passed the IRS Special Enrollment Examination (a three-part test covering individual taxation, business taxation, and representation procedures) or gained qualifying experience working at the IRS.⁵

A few other practitioners have limited rights. Enrolled actuaries and enrolled retirement plan agents can represent you within their specialty. An unenrolled return preparer who signed your return can represent you, but only on that return and only before examination, customer service, and Taxpayer Advocate Service personnel.⁶ Family members and full-time employees can sometimes act under narrow exceptions, but that rarely comes up.

Before naming anyone on Form 2848, it’s worth checking the IRS’s public list of disciplined tax professionals to confirm the person hasn’t been censured, suspended, or disbarred from practice.⁷

How to Complete Form 2848

Form 2848 is available on the IRS website and runs two pages. Accuracy matters: forms with mismatched names, wrong identification numbers, or vague descriptions of the tax matters covered get rejected.⁸

Your Information and Your Representative’s Information

You’ll need your full legal name, address, and either your Social Security Number or Employer Identification Number. For the representative, list name, address, phone number, and Centralized Authorization File (CAF) number if one has been assigned. A representative without a CAF number should note that on the form, and the IRS will generate one during processing. The representative must also state a professional designation (attorney, CPA, enrolled agent, and so on) and provide a license or enrollment number.

Tax Matters and Periods

Line 3 is where most mistakes happen. List each specific tax matter with its corresponding form number. Individual income tax is Form 1040. Quarterly payroll tax is Form 941. For civil penalties, write “civil penalty” and add the code section if you know it. Each entry needs an actual tax year or period. “All years” won’t work.

You can list future years, but the IRS will not record any future period on the CAF system that falls more than three years after December 31 of the year it receives the form.³ A form received in 2026 can reach 2029 at the furthest.

Signatures

Both you and the representative sign and date the form. If the taxpayer is a business entity, the signer must have legal authority to bind the organization. The representative signs Part II as a declaration of eligibility to practice before the IRS.

Forms submitted online accept several kinds of electronic signature: a typed name in the signature block, a scanned image of a handwritten signature, input from an electronic signature pad or stylus, or a signature generated by third-party software.⁹ Forms sent by fax or mail still need an ink signature.

Submitting the Form

There are three ways to get Form 2848 to the IRS, and processing speed varies sharply.

Tax Pro Account, at IRS.gov/TaxProAccount, is the fastest. Most authorizations submitted this way post to the CAF system within about 48 hours.⁹
The IRS online submission portal accepts uploads through secure messaging. It’s faster than mail but still processed by hand.
Fax or mail goes to the CAF unit listed in the Where To File Chart in the Form 2848 instructions. The destination depends on where the taxpayer lives or where the business is based.¹

For fax, mail, and portal submissions, processing can stretch beyond two weeks, and four weeks or more is not unusual during backlogs. If a collection deadline is close, use Tax Pro Account. Once the authorization is on the CAF system, your representative receives copies of IRS notices for the listed matters, and IRS employees can verify that authority during phone calls.

Form 2848 or Form 8821?

Form 2848 and Form 8821 look similar and go through the same channels, but they grant very different access. Form 8821 is a Tax Information Authorization: it lets someone view your tax records and receive information from the IRS, and nothing more. It does not let that person represent you, negotiate, sign, or make decisions.¹⁰ If all you need is for your accountant to pull transcripts, Form 8821 is enough. For an audit, a collections dispute, or anything where someone needs to act on your behalf, use Form 2848.⁸

Ending or Replacing the Authorization

You can revoke a tax power of attorney at any time. With a copy of the original Form 2848, write “REVOKE” across the top of the first page, sign and date beneath the annotation, and fax or mail it to the appropriate CAF unit. Without the original, send a signed and dated written statement identifying the representative by name and address, listing the tax matters and periods being revoked, and stating that you’re revoking the authority. To pull authority for everything at once, write “revoke all years/periods” instead of listing each one.³ A representative can withdraw by filing a similar written statement.

One automatic trigger catches people off guard. Filing a new Form 2848 for the same tax matters and periods automatically revokes any earlier power of attorney on file for those items. To keep an existing representative while adding a new one, check the box on Line 6 of the new form and attach a copy of the earlier Form 2848 you want to keep in effect.¹¹ Miss that checkbox and the IRS drops the prior representative when it processes the new form.

The authorization also ends automatically when the taxpayer dies, since a power of attorney is a personal grant that doesn’t survive the principal. After a death, the executor or personal representative typically files Form 56 (Notice Concerning Fiduciary Relationship) with court-approved letters testamentary to take over the decedent’s tax matters.¹² And a Form 2848 becomes ineffective if the representative loses professional standing: a CPA whose license lapses or an attorney who is disbarred can no longer practice before the IRS.

State Taxes Need Their Own Authorization

Form 2848 covers only federal tax matters. Most states require their own power of attorney form for state tax representation. A few states will accept the federal form, but that varies, and state forms sometimes carry requirements the federal form doesn’t, such as notarization or a witness signature. If you’re facing a federal audit and a state audit at once, plan to file separate authorizations for each.
