Form 2848: Power of Attorney and Declaration of Representative
Authorizes an individual to represent a taxpayer before the IRS, including the ability to receive confidential information, sign agreements, and advocate on behalf of the taxpayer.
Overview
IRS Form 2848, Power of Attorney and Declaration of Representative, is the mechanism by which a taxpayer formally authorizes another individual to represent them before the Internal Revenue Service. Once accepted, the designated representative can receive and inspect confidential tax information, execute agreements, consents, and waivers, and generally act in the taxpayer's place during audits, appeals, collection matters, and other IRS proceedings. The authority granted is specific — it covers only the tax matters, form types, and tax periods listed on the form — so a single Form 2848 filed for an audit of a 2023 individual return does not automatically extend to other years or entity types.
The form's legal basis flows from IRC § 7521 and the Treasury's Circular 230 (31 C.F.R. Part 10), which governs who may practice before the IRS and what that practice entails. Eligible representatives include attorneys, CPAs, enrolled agents, enrolled actuaries, enrolled retirement plan agents, and certain other individuals with specific relationships to the taxpayer (such as family members or full-time employees in limited circumstances). Each representative must include their PTIN (Preparer Tax Identification Number) and sign the Declaration of Representative in Part II, attesting to their authority and their understanding of Circular 230 obligations.
Form 2848 is distinct from Form 8821 (Tax Information Authorization), which allows a designee to receive and inspect tax information but does not grant the right to advocate, sign documents, or otherwise represent the taxpayer. CPAs and tax practitioners should understand this distinction clearly: use Form 2848 when active representation is needed, Form 8821 when read-only access to transcripts or notices is sufficient. The IRS maintains accepted Forms 2848 in the Centralized Authorization File (CAF) system, which allows IRS personnel across the country to verify an existing authorization without requiring the representative to resubmit the form for each interaction.
Who Files This Form?
There is no legal obligation to file Form 2848 — it is a voluntary authorization. However, any individual who wishes to have someone other than themselves speak to, negotiate with, or receive confidential information from the IRS on their behalf must have a valid Form 2848 on file (or present it at the time of the interaction).
The taxpayer executing the form can be an individual, a corporation, a partnership, a trust, an estate, or another legal entity. Joint filers (married couples filing jointly) who each want separate representation, or who want to authorize different representatives for the same return, must each sign the form. A taxpayer cannot designate a non-eligible individual — for example, a neighbor or an unlicensed accountant — as a representative under Form 2848; the representative must qualify under one of the categories listed in Part II.
A few important edge cases: Unenrolled return preparers are generally not eligible to be designated on Form 2848 and may only have limited representation rights during examinations of returns they prepared. Students working in an IRS-supervised Low Income Taxpayer Clinic or Student Tax Clinic program may be eligible under specific supervised-practice rules. A representative listed on a prior Form 2848 is automatically revoked when a new Form 2848 covering the same tax matters and periods is submitted, unless the taxpayer checks the box to retain prior authorizations.
There is no filing deadline for Form 2848 — it can be submitted at any point before or during an IRS proceeding. It can be mailed, faxed to the appropriate IRS fax number based on the state of the taxpayer's address, or submitted through the IRS Tax Pro Account for eligible individual taxpayers. Authorizations submitted through Tax Pro Account are processed in real time rather than being routed through the traditional CAF queue.
Key Fields
Part I, Line 1: Taxpayer Information
Enter the taxpayer's full name, address, Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Employer Identification Number (EIN) as applicable. For joint returns where both spouses are authorizing the same representative, both spouses' information must appear here and both must sign — a common oversight is listing only one spouse on a joint-return matter.
Part I, Line 2: Representative Information
Provide the name, address, telephone number, fax number, and CAF number for each representative (up to three may be listed on the printed form). The CAF number is assigned by the IRS after the first Form 2848 submission and should be used on all subsequent filings. Check the 'Check if new' box if a representative does not yet have a CAF number.
Part I, Line 3: Tax Matters
This is the heart of the authorization — specify the type of tax (e.g., Income, Employment, Estate, Gift), the tax form number (e.g., 1040, 1120, 941), and the specific years or periods covered. Leaving this vague or overly broad (such as writing 'all years') is not accepted by the IRS; you must list discrete periods. For employment taxes reported quarterly, list each quarter or use an inclusive range (e.g., '2023 Q1–Q4').
Part I, Line 4: Specific Use Not Recorded on CAF
Check this box only if the authorization is for a one-time or specific use that should not be stored in the CAF system — for example, a single appearance before an appeals officer for a specific hearing. If checked, the IRS will not record the power of attorney in the CAF, meaning IRS personnel outside that specific matter cannot access or verify the authorization.
Part I, Line 5a: Additional Acts Authorized
By default, Form 2848 authorizes a representative to perform most acts before the IRS, but certain acts require explicit authorization in Line 5a. These include the authority to substitute or add another representative, the ability to sign a tax return on behalf of the taxpayer (permitted only in narrow circumstances, such as taxpayer incapacity), and access to receive refund checks. If these authorities are needed, they must be specifically checked here.
Part I, Line 5b: Specific Acts Not Authorized
Taxpayers can restrict the scope of the representative's authority by listing acts the representative is NOT permitted to perform. This is less commonly used but important in situations where a taxpayer wants to retain direct control over certain decisions, such as signing closing agreements or consenting to extend the statute of limitations.
Part I, Line 6: Retention/Revocation of Prior Power of Attorney
When a new Form 2848 is filed for the same tax matters and periods as an existing authorization, the existing authorization is automatically revoked. If the taxpayer wants to keep prior representatives in addition to adding a new one, they must check the box on Line 6 and attach a copy of the previously filed Form 2848. Missing this step inadvertently terminates existing representatives.
Part I, Line 7: Taxpayer Signature and Date
The taxpayer (or each spouse on a joint return) must personally sign and date the form. For corporate or entity taxpayers, an authorized officer must sign and indicate their title. An undated signature is a common rejection reason — the IRS will not process Form 2848 without a dated taxpayer signature.
Part II: Declaration of Representative
Each representative must independently sign Part II, select the designation category that describes their authority to practice (e.g., 'b' for CPA, 'a' for attorney, 'f' for enrolled agent), provide their jurisdiction or enrollment information, and include their PTIN. This declaration is a legal attestation under Circular 230 — signing it without the proper credentials constitutes a violation.
Filing Deadlines
No penalty for the form itself; penalties apply for practicing before the IRS without proper authorization.
Step-by-Step Instructions
- 1
Gather the taxpayer's identifying information — full legal name, SSN/ITIN/EIN, and current address — and confirm the exact tax matters, form numbers, and tax periods that need to be covered by the authorization. Precision here avoids rejection or gaps in authority.
- 2
Complete Part I, Lines 1 through 3, entering the taxpayer information and listing each tax type, form number, and period on separate rows. If more rows are needed, attach a continuation sheet in the same format — do not use shorthand like 'all years' or 'all forms.'
- 3
Identify all representatives to be listed (up to three on the standard form) and enter their name, firm, address, telephone, fax, and CAF number in Line 2. For any representative without a CAF number, check the 'Check if new' box so the IRS assigns one upon processing.
- 4
Review Lines 4, 5a, and 5b to determine whether any non-standard authorization adjustments are needed. Most routine audit or collection representations require no changes here, but if the taxpayer wants the representative to be able to sign returns or receive refund checks, check the appropriate boxes in Line 5a.
- 5
Address Line 6 explicitly: if there are existing Forms 2848 on file for overlapping matters and the taxpayer intends to keep those prior representatives, check the retention box and attach a copy of the prior form. If revocation of all prior authorizations is intended, no action on Line 6 is needed.
- 6
Have the taxpayer(s) sign and date Part I, Line 7. For joint returns, both spouses must sign separately. For corporations, an officer with signing authority must sign and include their title. Verify that the signature date is included — it is one of the most common rejection triggers.
- 7
Have each representative complete and sign their section of Part II, selecting the correct designation code, providing license/enrollment details, and entering their PTIN. Verify the PTIN is current and active before submission.
- 8
Submit the completed form to the IRS by fax (preferred for speed) to the applicable CAF unit fax number based on the taxpayer's state of residence, by mail to the appropriate CAF unit, or electronically through the IRS Tax Pro Account portal for eligible individual taxpayer matters. Retain a copy for the client file.
- 9
Confirm CAF recording by checking the representative's Tax Pro Account or by contacting the IRS Practitioner Priority Service (PPS) line approximately two to three weeks after submission. If the form is rejected due to a technical deficiency, correct the identified issue and resubmit promptly to avoid gaps in authority during an active proceeding.
Common Mistakes to Avoid
Failing to obtain both spouses' signatures on a joint-return authorization.
For any tax matter relating to a jointly filed return, both spouses must sign Form 2848 individually. If only one spouse signs, the representative's authority is limited to that spouse's portion of the matter, which may be insufficient for most IRS interactions.
Listing 'all years' or 'all forms' instead of specific tax periods and form numbers.
The IRS requires discrete, specific entries for each tax type, form number, and year or period. List each year separately or use a clearly defined range (e.g., '2021, 2022, 2023') and the specific form number (e.g., '1040'). Vague entries are rejected.
Inadvertently revoking a prior representative by not checking the retention box on Line 6.
Before submitting a new Form 2848 that overlaps with an existing authorization, confirm with the client whether prior representatives should remain active. If so, check the Line 6 retention box and attach a copy of the prior form. Review the CAF before filing to identify any active authorizations.
Submitting the form without a taxpayer signature date.
An undated signature is one of the most frequent technical rejection reasons. Before faxing or mailing, perform a final checklist review confirming that the taxpayer's signature is accompanied by a date in Line 7.
Representatives signing Part II under the wrong designation code.
Each designation code in Part II carries specific practice rights and requirements. A CPA should select 'b,' an enrolled agent 'f,' and an attorney 'a.' Using the wrong code can create Circular 230 compliance issues and may cause the IRS to question the representative's authority.
Sending Form 2848 to the wrong IRS fax number or address.
The applicable CAF unit depends on the taxpayer's state of address, and the IRS periodically updates fax numbers. Always verify the current fax number in the official Form 2848 instructions before submission. A form sent to the wrong unit may be lost or significantly delayed.
Frequently Asked Questions
Form 2848 grants a representative full power of attorney to act on the taxpayer's behalf before the IRS — including the authority to advocate, negotiate, sign agreements, and receive confidential information. Form 8821 (Tax Information Authorization) only allows the designee to inspect and receive tax information; it does not authorize representation, negotiation, or signing. Use Form 2848 when active IRS representation is needed and Form 8821 when read-only transcript access is sufficient.
