Tax Power of Attorney (IRS Form 2848)

A Tax Power of Attorney in the United States delegates legal authority from a principal to a chosen agent, setting the scope and limits of that authority.

IRS Form 2848 and its requirements are governed by the Internal Revenue Code, Treasury Regulations, and Treasury Department Circular 230 (31 C.F.R. Part 10), which regulates practice before the IRS. Under Circular 230 § 10.3, only certain categories of persons are authorized to represent taxpayers before all administrative levels of the IRS: attorneys licensed in any US state; certified public accountants (CPAs) licensed in any US state; enrolled agents (EAs) — federally licensed tax practitioners who pass a complete IRS examination or qualify through prior IRS employment; enrolled actuaries for specific pension matters; and enrolled retirement plan agents for retirement plan matters. Each category of representative must state their credentials on Form 2848, including their Preparer Tax Identification Number (PTIN), bar number (for attorneys), CPA license number, or EA enrollment number.

Form 2848 has very specific technical requirements that distinguish it from a general financial power of attorney. The form must identify: the exact tax matters covered (each tax form number must be specified — e.g., Form 1040 for individual income tax, Form 1120 for corporate income tax, Form 941 for payroll taxes); the specific tax years or periods (no open-ended authorizations are accepted by the IRS — each year or period must be listed by year or by specific quarter for quarterly filers); and whether the representative has authority to receive refund checks, sign tax returns, or execute certain closing agreements (these are additional authorities beyond the basic representation grant and must be expressly stated in Line 5a of Form 2848).

The IRS processes Form 2848 submissions through its Centralized Authorization File (CAF) system, which maintains a database of all active POA authorizations. Once filed and processed (which typically takes two to four weeks for mail submissions, or can be faster through e-Services), the IRS will communicate with the authorized representative rather than the taxpayer for the specified matters. The CAF number assigned to the representative is a permanent identifier used across all future IRS matters.

A Tax POA aligned with IRS Form 2848 differs from a state tax power of attorney, which authorizes a representative to act before state tax authorities — California's Franchise Tax Board (FTB), New York's Department of Taxation and Finance (DTF), Texas Comptroller, Florida Department of Revenue, or other state agencies. State tax POAs may use Form 2848 as a model but must comply with each state agency's own requirements and are filed with the state agency, not the IRS.

The authority granted by Form 2848 is limited in important respects: a representative with Form 2848 authorization cannot substitute another representative without executing a new Form 2848; the authorization expires three years from the date signed unless the taxpayer specifies a different expiration date; and a new Form 2848 automatically revokes prior authorizations for the same tax matters, tax periods, and tax types, unless the taxpayer attaches the prior Form 2848 and checks the box indicating that prior representatives should not be revoked.

A Tax Power of Attorney aligned with IRS Form 2848 in the United States is needed whenever a taxpayer wants a licensed tax professional — a CPA, attorney, or enrolled agent — to represent them before the IRS in any examination, audit, appeal, or collection matter, or to communicate with IRS personnel on their behalf without the taxpayer's personal presence.

A Tax POA is needed when the IRS initiates an examination (audit) of a taxpayer's return. The IRS Examination Division selects returns for audit through various methods including computer scoring (the Discriminant Function System), document matching, and random selection. When a taxpayer receives a CP2000 notice (automated underreporter notice) or a formal audit notice, they need a Form 2848 to authorize their CPA or enrolled agent to respond to the IRS on their behalf and to prevent the IRS from contacting the taxpayer directly.

The document is needed when a taxpayer has unresolved tax liabilities and wants to work with the IRS Office of Appeals — an independent organization within the IRS that offers dispute resolution without litigation. An authorized representative with Form 2848 can communicate with Appeals officers, submit protest letters, negotiate proposed adjustments, and execute settlement agreements (closing agreements and Form 870, Waiver of Restrictions on Assessment).

A Tax POA is needed when a taxpayer has delinquent tax liabilities and wants their representative to negotiate an installment agreement (IA) under IRC § 6159, an Offer in Compromise (OIC) under IRC § 7122, Currently Not Collectible (CNC) status, or a penalty abatement request under IRC § 6651 or the IRS's First Time Penalty Abatement (FTA) policy. The IRS Collection Division requires Form 2848 before discussing a taxpayer's account details or collection options with a third party.

A Tax POA is needed for complex estate and gift tax matters — filings and examinations of Form 706 (United States Estate Tax Return) or Form 709 (United States Gift Tax Return) — where the estate's executor or the taxpayer wants an estate attorney or CPA to handle IRS correspondence and examination proceedings.

The document is needed when a taxpayer is unable to handle IRS communications personally due to illness, incapacity, language barriers, or the complexity of the tax issues involved. For elderly or incapacitated taxpayers whose affairs are managed under a financial POA, an additional Form 2848 must be filed specifically for IRS representation because the IRS's CAF system does not recognize general financial POAs as authorizing IRS representation.

A Tax Power of Attorney aligned with IRS Form 2848 must contain every element required by the IRS to be accepted for filing in the Centralized Authorization File (CAF) system and to authorize effective representation before the IRS.

The taxpayer identification clause must state the taxpayer's full legal name exactly as it appears on their tax return, the taxpayer's Social Security Number (SSN) or Employer Identification Number (EIN), and the taxpayer's current address. For joint filers, both spouses' names and SSNs must appear, and each spouse must sign the form separately. The taxpayer's daytime telephone number and fax number are also required.

The representative identification clause must state the representative's full legal name; their address and telephone number; their CAF number (if previously assigned by the IRS); their PTIN (Preparer Tax Identification Number); and their professional designation: attorney, CPA, enrolled agent, enrolled actuary, enrolled retirement plan agent, or other eligible category as specified in IRS Form 2848 instructions. The representative's bar number, CPA license number, or EA enrollment number must also be provided as applicable.

The tax matters covered clause is technically the most critical element. Each covered matter must identify: the specific tax form (e.g., Form 1040, Form 1120, Form 941, Form 706, Form 709); a description of the matter (e.g., 'Income Tax', 'Employment Tax', 'Estate Tax'); and the specific tax years or periods. For annual taxes, each year must be listed individually (e.g., '2021, 2022, 2023'). For quarterly taxes, each quarter must be listed (e.g., '1/1/2023 – 3/31/2023'). The IRS will not accept open-ended authorizations like 'all years' or 'all tax matters.'

The acts authorized (Line 5a) specifies additional authorities beyond standard representation. Standard representation under Form 2848 does not automatically authorize the representative to: receive refund checks; substitute another representative; sign the taxpayer's return; or execute certain closing agreements. Each of these additional authorities must be expressly stated in Line 5a if the taxpayer wishes to grant them.

The retention or revocation of prior authorizations (Line 6) addresses the effect of the new Form 2848 on prior authorizations covering the same tax matters and periods. By default, filing a new Form 2848 revokes all prior authorizations for the same matters and periods. If the taxpayer wants to retain a prior representative's authority alongside the new representative, the prior Form 2848 must be attached and the appropriate box checked.

The taxpayer signature and date clause requires the taxpayer (or a person authorized to sign on behalf of a business entity) to sign and date Form 2848. For individual taxpayers, the taxpayer signs personally. For corporations, the authorized officer signs. For partnerships, a general partner or LLC member signs. For estates, the executor or administrator signs. The signature date should match or precede the date the form is filed with the IRS.

The Declaration of Representative (Part II of Form 2848) must be signed by the representative under penalty of perjury, affirming that they are authorized to practice before the IRS under Circular 230, that they are not currently under suspension or disbarment from practice before the IRS, and that they will comply with all IRS regulations governing practice before the Service. This declaration is a mandatory element — a Form 2848 without Part II signed by the representative will be rejected by the IRS.

The filing procedure specifies that Form 2848 must be filed with the IRS by mail, fax, or through the IRS's Tax Pro Account online portal. The applicable IRS service center address for mailing or fax number depends on the taxpayer's state of residence, as specified in the Form 2848 instructions. Electronic submission through Tax Pro Account is the fastest processing method. Copies should be retained by both the taxpayer and the representative.
