Practice Before the IRS: Representation Rights and Authorization Forms

Practice before the IRS is a regulated activity, and only certain credentialed professionals are authorized to do it on someone else’s behalf. Attorneys in good standing with a state bar, licensed CPAs, and enrolled agents can represent any taxpayer on any tax matter before any IRS office. Several other categories, including Annual Filing Season Program participants and enrolled actuaries, can represent taxpayers only in narrower circumstances. You can always represent yourself; if you want someone else to act for you, they must meet these credentialing rules and you must sign an authorization form.¹

What Practice Before the IRS Covers

The phrase has a broader reach than most people expect. It covers any communication with IRS personnel about a taxpayer’s rights or obligations under federal tax law: filing documents, corresponding with the agency, representing someone at a meeting or hearing, and providing written tax advice. The definition reaches every administrative level of the agency, including examinations, collections, and the Office of Appeals.²

One distinction catches people off guard. Simply preparing a return is not “practice before the IRS.” Anyone can prepare or help prepare a return for compensation, appear as a witness for a taxpayer, or furnish information the IRS requests. Those activities sit outside the regulatory definition.³ The line gets crossed when the preparer starts advocating a position, negotiating with IRS personnel, or providing written tax advice. That’s when the rules in Treasury Department Circular 230 apply.

Who Can Represent You

Representation authority breaks into two tiers.

Unlimited Representation Rights

Three groups can handle any matter, in any IRS office, for any taxpayer. Attorneys who are members in good standing of a state bar qualify by filing a written declaration of their qualifications. CPAs with active licenses have the same broad authority. Enrolled agents earn their designation either by passing all three parts of the Special Enrollment Examination or, for certain former IRS employees, through qualifying technical experience.¹

Limited Representation Rights

Enrolled actuaries and enrolled retirement plan agents can represent taxpayers only on issues within their professional specialties, such as pension plan determinations and employee plan compliance matters.¹

Annual Filing Season Program participants occupy a middle ground. After completing required continuing education and obtaining a Record of Completion, they can represent clients whose returns they personally prepared and signed. That authority extends only to revenue agents, customer service representatives, and the Taxpayer Advocate Service. AFSP participants cannot represent taxpayers in appeals or collection matters.⁴

Uncredentialed Preparers

Tax return preparers who hold no credential and haven’t completed the AFSP face the tightest restrictions. For returns prepared and signed after December 31, 2015, an unenrolled preparer needs both a valid Preparer Tax Identification Number and an AFSP Record of Completion for the relevant year to represent anyone at all during an examination. Without those, the preparer can’t represent the taxpayer. They can still be authorized to receive tax information through Form 8821.⁵

The Forms That Put Representation in Place

Two pieces need to be in place before a representative can act: the representative’s own credentials and a signed authorization from you.

Preparer Tax Identification Number

Anyone who prepares or helps prepare federal tax returns for compensation must hold a valid PTIN and include it on every return filed. PTINs expire on December 31 each year, and the renewal fee for 2026 is $18.75 (non-refundable). Online renewal takes about 15 minutes; paper applications on Form W-12 can take six weeks to process.⁶

Form 2848: Power of Attorney

Form 2848, Power of Attorney and Declaration of Representative, is the primary document that grants someone the legal authority to act on your behalf. It authorizes the representative to sign agreements, receive confidential information, and perform essentially any act you could perform on the listed matters.⁵ The form requires your name, address, and identification number (Social Security Number or Employer Identification Number), along with the representative’s Centralized Authorization File number, a unique nine-digit identifier the IRS assigns to track authorized representatives.⁷

The form must list each specific tax matter (such as “Income, 1040” or “Employment, 941”) and the years or periods covered. Vague entries like “All Years” or “All future periods” will get the form rejected.⁸

Form 8821: Tax Information Authorization

When the goal is more limited, allowing a third party to view or receive your confidential tax information without actually representing you, Form 8821 is the right form. It authorizes an individual or organization to inspect and receive tax information for the types of tax and periods listed on the form. It does not grant the power to advocate or act on your behalf.⁹

How to Submit the Authorization

Three routes exist, and the choice affects how long you wait.

The fastest is Tax Pro Account, a digital portal where a practitioner requests authorization directly from an individual taxpayer. You review and electronically approve the request through your IRS Online Account, and the authorization processes in real time. This option is currently limited to authorization requests involving individual taxpayers.¹⁰

The second option is the Submit Forms 2848 and 8821 Online tool, which lets practitioners securely upload scanned, signed copies.¹¹ Traditional mail and fax remain available; completed forms go to the CAF Unit for the taxpayer’s geographic region. Paper and fax submissions for both forms are typically processed within 8 business days of receipt.¹²

Common Reasons for Rejection

The CAF Unit rejects a surprising number of submissions for avoidable technical errors. On Form 2848, the frequent problems include missing signatures or signature dates, vague descriptions of tax matters or periods, missing representative designation or jurisdiction information, and failing to indicate the title of a business taxpayer signing the form. If you check the box to retain a prior power of attorney, you must attach a copy identifying which representative you’re retaining; leaving that out triggers an automatic rejection. Form 8821 rejections most often stem from missing taxpayer signatures, vague tax matter descriptions, or incorrect identification numbers.⁸

Ending or Changing Representation

You can end a representative’s authority at any time. The simplest approach when switching representatives is to file a new Form 2848 for the same tax matters and periods. This automatically revokes the prior power of attorney unless the new form explicitly states otherwise and includes a copy of (or reference to) the prior authorization.¹³

To revoke without naming a new representative, write “REVOKE” across the top of the first page, sign and date it, then mail or fax the marked-up copy to the appropriate CAF Unit. If you no longer have the original form, send a signed statement identifying the representative being revoked, the tax matters and periods involved, and your taxpayer identification number. Writing “revoke all years/periods” covers everything at once.⁵

A representative who wants to withdraw follows a similar process: write “WITHDRAW” across the top of the power of attorney, sign and date below the annotation, and send it to the IRS.⁵

Ethical Rules Your Representative Must Follow

Circular 230 governs how authorized practitioners must behave. A few of its rules matter directly to the client relationship.

Due Diligence and Error Notification

Every practitioner must exercise due diligence in preparing returns, approving documents, and making representations to both the IRS and their own clients. That means verifying the accuracy of statements before submitting them and using reasonable care when relying on someone else’s work product.¹⁴

When a practitioner discovers that a client hasn’t complied with federal tax law or has made an error in a previously filed return, the practitioner must promptly notify the client and explain the consequences. The regulation gives no discretion to decide whether the error is “big enough” to mention; any known noncompliance, error, or omission triggers the duty.¹⁵

Conflicts of Interest

A practitioner who has a conflict of interest between two clients can still represent both, but only if the practitioner reasonably believes they can provide competent representation to each, the representation isn’t prohibited by law, and every affected client gives informed consent confirmed in writing. That written confirmation must happen within 30 days of when the practitioner becomes aware of the conflict, and the practitioner must keep copies for at least 36 months after the representation ends.¹⁶

Fee Restrictions

Contingent fees, where the practitioner’s compensation depends on the outcome, are generally prohibited for IRS matters. Your representative can’t charge a fee based on a percentage of your refund or on how much tax is saved. The ban extends to fee arrangements where the practitioner reimburses you if the IRS challenges a position, regardless of how the reimbursement is structured.¹⁷

Three narrow exceptions apply. A practitioner can charge a contingent fee when representing a client during an IRS examination of an original return, when filing a claim solely about statutory interest or penalties assessed by the IRS, or in connection with a judicial proceeding under the Internal Revenue Code. An amended return qualifies for the examination exception only if it was filed within 120 days of the taxpayer receiving written notice of the exam.¹⁷

What Happens When a Representative Breaks the Rules

The Office of Professional Responsibility enforces Circular 230. After notice and a hearing, the Secretary of the Treasury (or delegate) can censure, suspend, or permanently disbar any practitioner shown to be incompetent, engaged in disreputable conduct, or in violation of the regulations. Censure is a public reprimand; suspension and disbarment remove the practitioner’s authority to represent taxpayers for a defined period or permanently.¹⁸

Financial penalties can be imposed on top of or instead of these disciplinary measures. The maximum penalty equals the gross income the practitioner earned (or expected to earn) from the conduct that triggered the sanction. If the practitioner was acting on behalf of a firm or employer that knew or should have known about the misconduct, the firm itself can be penalized as well.¹⁸
