IRS Form 13424-P Guide: Special Appearance Authorization

1. Introduction: What is Form 13424-P?

IRS Form 13424-P, officially titled the Application for Special Appearance Authorization, is an administrative credentialing document issued by the Internal Revenue Service (IRS). The IRS is a federal bureau of the United States Department of the Treasury charged with administering federal tax laws and overseeing tax practice standards.

Unlike personal tax returns or business income schedules, Form 13424-P is an institutional authorization form used in clinical legal education and pro bono legal assistance. The form is managed by the Taxpayer Advocate Service (TAS) through the national Low Income Taxpayer Clinic (LITC) Program Office.

Under Section 10.7(d) of Treasury Department Circular No. 230 and Delegation Order 25-18, the Director of the LITC Program Office has the legal authority to grant special practice rights. Form 13424-P allows qualifying tax clinics to request permission for enrolled law students, business students, accounting students, and recent law graduates to represent taxpayers before the IRS without holding a standard professional license.

2. Purpose of the Form

Under federal regulations governing practice before the IRS (Circular 230), only licensed attorneys, Certified Public Accountants (CPAs), and Enrolled Agents (EAs) are legally permitted to represent taxpayers in audits, administrative appeals, and collection negotiations. Without a formal license, an individual cannot advocate on a taxpayer’s behalf, negotiate tax debts, or inspect confidential tax records.

However, academic tax clinics and legal aid programs rely heavily on students and recent law graduates to deliver free legal advocacy to low-income filers. These clinical programs give students essential experiential training while expanding access to justice for taxpayers who cannot afford private counsel.

Form 13424-P solves this licensing obstacle by establishing a formal exception. When approved, the IRS issues an official Special Appearance Authorization letter. This letter permits qualifying students and unadmitted law graduates to file powers of attorney, speak directly with IRS examiners, and represent clients under the direct supervision of a licensed practitioner.

3. Who Needs to File This Form

Form 13424-P is an institutional application form that must be completed and submitted by clinic leadership rather than individual students or clients. You need to file this form if you hold either of the following roles:

• LITC Clinic Directors & Supervising Practitioners: Leaders of federally funded Low Income Taxpayer Clinics at law schools, business schools, or civil legal aid societies who wish to authorize student interns and recent law graduates to handle IRS controversy casework.
• Student Tax Clinic Program (STCP) Directors: Faculty directors of non-funded academic tax clinics at accredited universities that meet IRS clinical standards and desire special appearance authority for enrolled students.

Individual law or accounting students do not complete Form 13424-P directly. Instead, the lead supervising practitioner submits the application on behalf of the clinic’s entire student roster.

4. Who Is Exempt / Not Required to File

Because Form 13424-P is specifically tailored to student advocacy in approved clinical settings, most practitioners and organizations are exempt from filing it:

• Fully Credentialed Tax Practitioners: Licensed attorneys, CPAs, and Enrolled Agents already possess unlimited practice rights under Circular 230 Section 10.3 and do not need special appearance authorizations.
• Individual Taxpayers: Low-income clients represented by a clinic never complete or interact with this form.
• Admitted Law Graduates: Law graduates who have already passed the bar exam and been formally admitted to practice law represent taxpayers under standard attorney authority on Form 2848.
• Volunteer Tax Preparation Sites (VITA/TCE): Volunteers working with the Volunteer Income Tax Assistance or Tax Counseling for the Elderly programs prepare returns rather than handle legal controversy representation, making Circular 230 practice authorizations unnecessary.
• Clinics Without Student Advocates: Non-profit legal clinics where all IRS representations are handled exclusively by licensed staff attorneys or CPAs without student involvement.

5. When to File

Form 13424-P operates on an academic-term or grant-year schedule rather than an annual tax filing deadline:

• Prior to Academic Semesters: Academic clinics typically submit Form 13424-P several weeks before the beginning of each semester (Fall, Spring, or Summer) to ensure students receive authorization before clinic casework begins.
• Prior to Direct Representation: Form 13424-P must be submitted, reviewed, and approved by the LITC Program Office before any student contacts an IRS revenue agent, attends a conference, or files a power of attorney.
• Mid-Year Roster Additions: If new students or law graduates join the clinic mid-term, the clinic must submit an updated request before those individuals begin handling client cases.

Authorizations are granted for a specified term, typically aligning with the academic calendar or the LITC grant year. Clinics must renew their authorizations periodically to maintain continuous student practice rights.

6. Where and How to File

Form 13424-P cannot be filed through consumer tax preparation software or standard IRS public e-filing systems. It must be delivered through specialized administrative channels directly to the LITC Program Office.

Clinics submit Form 13424-P alongside its companion roster document, Form 13424-Q (LITC or STCP Student and Law Graduate Information Chart). The completed forms are typically transmitted via secure digital upload through the LITC Grants Portal, by password-protected email, or by dedicated agency facsimile as outlined in IRS Publication 3319.

If instructed to send hard-copy documentation, academic transcripts, or supervisor resumes by mail, deliver materials to the specific IRS address as per instructions in Publication 3319. Once approved, the LITC Program Office issues a formal authorization letter that the clinic must retain on file and attach to all client representation paperwork.

7. Step-by-Step Instructions to Fill the Form

Form 13424-P captures essential administrative data regarding the clinic, its supervising practitioners, and its student supervision protocols. Review the table below for a section-by-section guide.

Form Section	Required Information	Instructions for Clinic Directors
Clinic Profile	Clinic Name & Sponsoring Entity	Enter the official clinic name, university or legal aid organization, address, and LITC grant number (or STCP identifier).
Program Classification	Clinical Structure	Indicate whether the clinic is an Academic LITC, a Non-Academic LITC with student interns, or an unfunded academic STCP.
Lead Supervising Practitioner	Director / Supervisor Details	Provide the legal name, contact information, professional title, and Centralized Authorization File (CAF) number of the supervising attorney or CPA.

Understanding Companion Form 13424-Q

Form 13424-P cannot be submitted alone; it must be accompanied by Form 13424-Q (Student and Law Graduate Information Chart). On Form 13424-Q, clinic directors list the following details for every individual seeking authorization:

• Student Full Legal Name: The exact name that will appear on client Powers of Attorney.
• Academic Status: Classification as a 2L/3L law student, graduate LL.M. tax student, business student, undergraduate accounting student, or recent law graduate.
• Degree Program & School: The accredited institution where the student is currently enrolled or recently graduated.
• Law Graduate Qualifications: For recent law graduates, verification that the graduate has not been admitted to any bar and has never been denied bar admission due to moral character or fitness grounds.

8. Required Documents/Information Needed Before Filling

Before submitting Form 13424-P to the LITC Program Office, compile the following supporting records:

• Form 13424-Q: A completed Information Chart listing all participating students and graduates for the upcoming session.
• Supervisor Resumes & Licenses: Current proof of active, good-standing bar licenses, CPA registrations, or Enrolled Agent credentials for all supervising practitioners.
• Academic Accreditation Documentation: Proof of regional or legal accreditation (such as American Bar Association accreditation) for academic institutions applying under the STCP program.
• Written Clinical Supervision Plan: A concise outline explaining how student casework, correspondence, and client conferences will be monitored by licensed staff.
• Graduation Verification: Official graduation dates or registrar letters for any law graduates participating prior to bar admission.

9. Common Mistakes to Avoid

Procedural errors on Form 13424-P can delay student casework or lead to rejected powers of attorney. Watch out for these frequent mistakes:

• Submitting Without Form 13424-Q: Form 13424-P serves as the clinic’s application, while Form 13424-Q provides the actual roster. Submitting Form 13424-P without the student chart will result in an immediate rejection.
• Allowing Early Student Appearances: Students cannot communicate with the IRS or sign representation forms until the LITC Program Office formally issues the approval letter. Early practice constitutes unauthorized practice before the IRS.
• Forgetting to Attach the Authorization to Form 2848: When submitting Form 2848 to the IRS CAF unit, clinics must attach a copy of the TAS Special Appearance Authorization letter. Omitting the letter causes the IRS to reject the student’s representative status.
• Listing Ineligible Law Graduates: A law graduate who has failed a state bar character and fitness review or who has been denied bar admission cannot qualify for a special appearance authorization.
• Ignoring the 130-Day CAF Expiration: The IRS Centralized Authorization File (CAF) system automatically purges student representatives 130 calendar days after the taxpayer signs Form 2848. If a case extends beyond 130 days, a renewed Form 2848 must be executed.

10. Penalties for Non-Filing or Errors

Because Form 13424-P is an administrative application rather than a tax return, failing to submit it does not trigger civil tax penalties. However, the legal and ethical consequences of unauthorized practice are severe:

• Rejection of Client Representation: The IRS will refuse to recognize the student as an authorized representative, declining to discuss case facts, share transcripts, or negotiate settlements.
• Referral to the Office of Professional Responsibility (OPR): If a licensed practitioner permits an unapproved student to practice before the IRS, the supervising attorney or CPA can be investigated by OPR for aiding unauthorized practice under Circular 230 Section 10.51.
• Sanctions on Supervising Practitioners: Supervisors found in violation of Circular 230 face disciplinary actions ranging from formal reprimands to suspension or disbarment from practice before the IRS.
• Grant Suspension: LITC grantees that permit unauthorized representation risk losing their federal grant funding for non-compliance with Quality Site Requirements.
• False Statements Penalties: Intentionally falsifying supervisor credentials or student enrollment status violates 18 U.S.C. Section 1001, carrying criminal fines and potential imprisonment.

12. Frequently Asked Questions

What specific acts can a student perform once authorized?

Authorized students and law graduates may perform virtually all representative acts permitted on Form 2848. This includes interviewing clients, communicating with IRS examiners, negotiating installment agreements or Offers in Compromise, and participating in conferences with the IRS Independent Office of Appeals, all under direct practitioner supervision.

How is Form 2848 completed for an authorized student?

On Line 2 of Form 2848, the lead supervising attorney or CPA must be listed first, followed by the student. In Part II (Declaration of Representative), the student checks designation “k” (Qualifying Student), enters “LITC” or “STCP,” and attaches a copy of the TAS Special Appearance Authorization letter.

What is the 130-day CAF purge rule?

To reflect the temporary nature of academic semesters, the IRS Centralized Authorization File (CAF) system automatically deletes student authorizations 130 days after the taxpayer signs Form 2848. If a student continues working on the case in a subsequent semester, a new Form 2848 must be submitted.

Must the supervising practitioner participate in every phone call with the IRS?

Supervisors must maintain direct oversight of all casework. While some experienced students may handle routine informational calls under approved guidelines, supervising practitioners must review all written correspondence, co-sign major filings, and participate in substantive negotiations or conferences.

Can undergraduate accounting students be authorized on Form 13424-P?

Yes. Students enrolled in accredited undergraduate accounting or business programs can receive authorization, provided they are participating in an approved academic clinic or LITC and work under the direct supervision of a licensed attorney, CPA, or Enrolled Agent.

Can a student appear in the United States Tax Court using this authorization?

No. Form 13424-P authorizes practice strictly before the Internal Revenue Service (an executive agency). Appearances before the United States Tax Court are governed separately by the Tax Court Rules of Practice and Procedure under student practice orders issued directly by the court.
