How to Complete IRS Form 2848 Power of Attorney

To fill out IRS Form 2848, enter your identifying information on Line 1, list each representative with their CAF number and credentials on Line 2, spell out every tax matter and period on Line 3, check any additional powers you want to grant on Line 5a, decide on Line 6 whether to keep prior authorizations in force, sign and date Line 7, and have each representative complete and sign Part II. The IRS rejects forms with vague periods, missing signatures, missing dates, missing titles, or missing license numbers, so precision on each line matters more than on almost any other IRS form.

Confirm You Need Form 2848 and Not Form 8821

Form 2848 grants a power of attorney: your representative can act on your behalf, negotiate with the IRS, sign agreements, and make decisions about your tax matters.¹ Form 8821 only lets someone view your tax information; it does not authorize them to speak or act for you.² A Form 2848 already includes the access an 8821 would grant, so there’s no reason to file both.

Who You Can Name on Line 2

The IRS limits representation to individuals in specific categories: attorneys, certified public accountants, and enrolled agents.³ Enrolled retirement plan agents can represent you on retirement plan matters, and enrolled actuaries handle actuarial issues.

Preparers who hold a Record of Completion from the IRS Annual Filing Season Program can represent clients before revenue agents, customer service representatives, and the Taxpayer Advocate Service, but only for returns they personally prepared and signed.⁴ Unenrolled preparers without that credential have narrower authority. In limited situations, a family member, corporate officer, or full-time employee of a business can represent the taxpayer based on their relationship.

Part I: Filling In Lines 1 Through 7

Line 1: Taxpayer Information

Enter your full legal name, current mailing address, and taxpayer identification number. Individuals use a Social Security number; businesses use an employer identification number. Include a daytime phone number.⁵ Spouses filing jointly who want the same representative can list both names and both Social Security numbers on a single form. If each spouse wants a different representative, file separate forms.

Line 2: Representative Information

List each representative’s full name, mailing address, phone number, fax number, and professional designation. Each representative must also provide their Centralized Authorization File (CAF) number, which is the unique number the IRS uses to track authorizations. If it’s the representative’s first time being named on any power of attorney, they enter “None,” and the IRS assigns a number during processing.⁶ You can name multiple representatives on one form.

Line 3: Tax Matters and Periods

This is where most rejections happen. Each tax matter goes on its own row with three pieces of information: a description of the matter, the tax form number, and the specific year or period. A typical row would read “Income” for the description, “1040” for the form number, and “2024” for the period. For quarterly filings, ranges work, such as “1st 2024–4th 2025.”⁵

The IRS rejects any form that uses vague references like “All years,” “All periods,” or “All taxes.”⁷ Spell out each matter and time period. Your representative’s authority extends only to what appears on Line 3, so leaving off a year means the IRS will not discuss it with them.

You can include future tax years, but the IRS won’t record any future period that exceeds three years from December 31 of the year the form is received.⁵ A form received in 2026 can cover future periods through 2029 at the latest. For estate tax matters, enter the decedent’s date of death instead of a year.

Line 5a and 5b: Additional and Excluded Acts

Your representative automatically gets authority to receive and inspect your confidential tax information and to perform most routine acts on your behalf, such as signing agreements and responding to IRS inquiries. Several powers, though, are excluded unless you check the corresponding box on Line 5a:⁶

Signing a return on your behalf. This is separate from general representation authority.
Substituting or adding representatives. Without this, your representative can’t bring in a colleague or transfer your case.
Accessing records through an Intermediate Service Provider, which allows electronic access through third-party systems.
Disclosing your tax information to third parties, such as a mortgage lender.

Line 5b does the opposite. If there are specific acts you want carved out of the general authority, list them there.

Line 6: Retaining Prior Powers of Attorney

Filing a new Form 2848 automatically revokes any prior power of attorney for the same tax matters and periods.⁸ If you already have a representative on file and want to keep them while adding a new one, check the box on Line 6 and attach a copy of the earlier power of attorney. Skip that step and the IRS removes the original representative. Check the box without attaching the prior authorization and the IRS rejects the form.⁷

Line 7: Taxpayer Signature

Sign and date the form. For mailed or faxed submissions the signature must be handwritten in ink; digital or typed signatures aren’t valid through those channels.⁵ For a business entity, the person signing must be authorized to act for the organization, such as a corporate officer or general partner, and their title must appear on the form. Omitting the title is a common rejection trigger.⁷

Part II: The Representative’s Declaration

Each representative listed on Line 2 must complete and sign Part II. They enter their designation letter (for example, “a” for attorney, “b” for CPA, “c” for enrolled agent), their licensing jurisdiction, and their bar number, license number, or enrollment number. Missing any of these fields will get the form rejected.⁷ By signing, the representative affirms they are authorized to practice before the IRS and are not currently suspended or disbarred.

The 45-Day Signature Rule

Usually the taxpayer signs first, granting the authority, and the representative signs afterward to accept it. When it happens in that order, the representative has 45 days from the taxpayer’s signature date to sign for domestic authorizations, or 60 days if the taxpayer resides abroad.⁵ If the representative signs first, the 45-day rule doesn’t apply.⁹ Once both signatures are on the form, there’s no separate deadline to submit it.

Signature Format Depends on How You Submit

Mail and fax require handwritten ink signatures from both the taxpayer and the representative. Online submissions accept several types of electronic signatures:¹⁰

A typed name in the signature block
A scanned image of a handwritten signature
A signature drawn on a touchscreen with a stylus
A signature captured on an electronic signature pad
A signature created through third-party software

When a taxpayer signs electronically in a remote transaction and the tax professional doesn’t have a prior personal or business relationship with them, the professional has to verify the taxpayer’s identity. That means inspecting a government-issued photo ID on a video call or a photo the taxpayer takes of themselves, recording the taxpayer’s name and identification number, and verifying that information against secondary documentation such as a prior tax return or Social Security card.⁵ For a business entity, the professional also confirms the signer has authority to act on the organization’s behalf.

Where to Submit the Completed Form

The IRS offers three submission channels, and they don’t process at the same speed.

Tax Pro Account is the fastest. Tax professionals who use this portal get real-time processing for individual power of attorney requests, and the authorization posts to the Centralized Authorization File system immediately.¹⁰

Submit Forms Online is the IRS portal for uploading a signed Form 2848 digitally. It accepts electronic or handwritten signatures, but forms process in the order received, the same as fax and mail.¹¹

Fax and mail are still available. Handwritten signatures are required for both. The IRS routes submissions geographically: states west of the Mississippi generally go to the Ogden processing center, states east of the Mississippi go to Memphis, and international authorizations go to Philadelphia.¹²

Processing times for non-real-time submissions vary, and during backlog periods they’ve stretched to several weeks. If a representative tries to contact the IRS before the authorization appears in the CAF system, the agency won’t discuss the account. When responding to an IRS notice, attaching a copy of Form 2848 to the response lets the assigned agent see the authorization immediately, even before the CAF system finishes processing.

Rejection Checklist Before You Send It

The IRS publishes the errors that come up most often, and each one is avoidable:⁷

Missing signatures or dates. Both the taxpayer and the representative must sign and date. A missing date alone triggers rejection.
Vague tax period descriptions. Entries like “All years” or “All future periods” on Line 3 will be returned.
Line 6 checked without the prior POA attached.
Missing designation letter or licensing jurisdiction in Part II.
Missing license or enrollment number: bar number for attorneys, license number for CPAs, enrollment number for enrolled agents.
A business signer with no title indicated.

A rejection restarts the processing clock, so walking through this list before sending saves weeks.

Fiduciaries, Estates, and Dissolved Entities

When someone signs Form 2848 on behalf of a taxpayer who cannot sign for themselves, the rules shift. A fiduciary — executor, trustee, administrator, or guardian — stands in the position of the taxpayer, not the representative. The fiduciary signs Line 7 as the taxpayer, not Part II.⁵

For a deceased taxpayer’s estate, the executor or administrator signs the form and should separately file Form 56, Notice Concerning Fiduciary Relationship, to formally establish the fiduciary role with the IRS.⁵ For a dissolved corporation, the signer must be able to document authority to act for the entity, such as the last corporate officer or a court-appointed receiver, and the IRS may require supporting documentation like corporate resolutions or court orders.
