1. Introduction: What is Form 15115?

IRS Form 15115, officially titled Request for Missing Information on the Application for Enrollment or Renewal of Enrollment to Practice before the IRS, is an administrative compliance and inquiry document published by the Internal Revenue Service (IRS). It is governed by the Return Preparer Office (RPO), specifically the Enrolled Agent Policy & Management (EAP&M) unit, under the legal authority of Treasury Department Circular No. 230 (Title 31 of the Code of Federal Regulations, Part 10).

This form is not a tax return filed by general taxpayers or businesses. Instead, it is sent to tax professionals—primarily candidates and active practitioners seeking to become or remain Enrolled Agents (EAs) or Enrolled Retirement Plan Agents (ERPAs). When an applicant submits an initial application for enrollment (Form 23) or a renewal application (Form 8554 or Form 8554-EP) that contains omissions, missing documentation, or unverified credentials, the IRS issues Form 15115 as an official request to cure those deficiencies before a final decision is made.

2. Purpose of the Form: Why Does Form 15115 Exist?

An Enrolled Agent is a federally authorized tax practitioner who has demonstrated technical competence in federal taxation and is empowered by the U.S. Department of the Treasury to represent taxpayers before all administrative levels of the IRS, including audits, collections, and appeals. To protect the public and uphold the integrity of the tax system, the IRS enforces strict professional, educational, and ethical standards under Circular 230.

When an individual applies for initial enrollment or periodic renewal, the IRS must verify that the applicant passed all three parts of the Special Enrollment Examination (SEE), completed mandatory continuing education (CE) hours, holds an active Preparer Tax Identification Number (PTIN), and passed a comprehensive tax compliance and background suitability check. Form 15115 exists to streamline this oversight process:

Preventing Application Denials: Instead of outright rejecting an incomplete application and forcing the practitioner to repay non-refundable application fees, Form 15115 gives the applicant a formal opportunity to provide missing records.
Verifying Continuing Education (CE) Compliance: Enrolled Agents must complete 72 hours of continuing education every three years, including mandatory annual ethics courses. Form 15115 allows practitioners to substantiate CE credits when third-party provider reporting is incomplete.
Resolving Suitability and Tax Compliance Issues: Circular 230 requires practitioners to maintain a clean personal tax filing and payment record. Form 15115 gives applicants an avenue to provide proof that personal or business tax balances have been paid or placed in an approved installment agreement.

3. Who Needs to File This Form?

Form 15115 is an inquiry-driven response document that you only complete if you receive it directly from the IRS Return Preparer Office. You need to complete and submit Form 15115 if:

You submitted Form 23 (Application for Enrollment to Practice Before the IRS) to become an Enrolled Agent, and the IRS identified missing examination records, signatures, or background details.
You submitted Form 8554 (Application for Renewal of Enrollment) or Form 8554-EP, and the IRS flagged gaps in your reported continuing education credits or unverified ethics hours.
Your application was paused due to a discrepancy with your Preparer Tax Identification Number (PTIN) or personal contact information.
The IRS suitability check identified unfiled personal tax returns or unpaid federal tax liabilities that require clarification or proof of payment.

4. Who Is Exempt / Not Required to File?

Because Form 15115 is restricted strictly to federal practitioner licensing under Circular 230, large segments of tax professionals and taxpayers do not use it:

Attorneys and Certified Public Accountants (CPAs): Licensed attorneys and CPAs practice before the IRS under the authority of their state professional licenses (pursuant to Circular 230 Section 10.3) and do not obtain Enrolled Agent credentials unless they choose to hold dual designations.
Practitioners with Approved Applications: Enrolled Agents whose initial enrollment or renewal forms were approved and processed without discrepancy never receive Form 15115.
Unenrolled Tax Preparers: Annual Filing Season Program (AFSP) participants and general tax preparers who do not possess unlimited representation rights do not file this form.
General Individual and Business Taxpayers: Everyday taxpayers resolving personal audits, business returns, or refunds have no involvement with this practitioner licensing form.

5. When to File: Deadlines and Frequency

Form 15115 is an event-based response document rather than an annual recurring filing. It carries a strict administrative deadline printed directly on the accompanying correspondence.

The IRS Return Preparer Office typically requires applicants to submit Form 15115 and all requested records within 30 to 60 calendar days from the date printed on the letter. Meeting this deadline is critical: if you fail to respond on time, the IRS will reject your application as abandoned, your non-refundable user fee will be forfeited, and your active enrollment status will lapse. If you are an existing Enrolled Agent whose renewal cycle ends while the application is paused, failing to respond promptly can result in your credential being placed in inactive status, legally barring you from representing clients before the IRS.

6. Where and How to File

Form 15115 is processed directly by specialized licensing units within the IRS Return Preparer Office and cannot be submitted through standard e-file tax software:

Submission by Secure Fax (Recommended): Many Form 15115 notices include a dedicated, toll-free secure fax number directly to the Enrolled Agent Policy & Management team. Faxing is generally the fastest way to deliver missing certificates and avoid processing delays. Always keep your fax transmission confirmation sheet.
Submission by Mail: If returning by mail, send the completed Form 15115 and clear copies of your supporting documents to the designated IRS address as per instructions printed on your letter (typically the IRS Return Preparer Office / Enrolled Agent Processing Center in Washington, DC, or Cincinnati, Ohio). Always use certified mail with tracking.
Never Send Original Certificates: Submit legible photocopies of continuing education certificates, examination score sheets, or court records. The IRS does not guarantee the return of original documents.

7. Step-by-Step Instructions to Fill Form 15115

Form 15115 is organized into practitioner identification fields, application reference checkboxes, and specific missing information categories. The table below outlines each section of the form.

Section	Field / Topic	Required Information & Instructions
Header	Practitioner Identification	Full legal name, Enrollment Number (if renewal), SSN or ITIN, active PTIN, address, and phone number.
Application Type	Form Reference	Checkbox indicating whether the inquiry relates to Form 23 (Initial) or Form 8554 / 8554-EP (Renewal).

Execution	Applicant Signature	Original signature and execution date verifying under penalties of perjury that all answers are true.

Part 1: Practitioner Identification

Enter your full legal name exactly as shown on your original Form 23 or Form 8554. If you are an existing Enrolled Agent renewing your license, provide your permanent six-digit or seven-digit Enrollment Number. Enter your Social Security Number (SSN) and your active Preparer Tax Identification Number (PTIN, which begins with the letter P). Provide your current mailing address, daytime telephone number, and professional email address.

Part 2: Identifying the Underlying Application

Check the box that corresponds to the application you previously submitted:

Form 23: Initial application for enrollment to practice before the IRS.
Form 8554: Periodic application for renewal of enrollment as an Enrolled Agent.
Form 8554-EP: Periodic application for renewal of enrollment as an Enrolled Retirement Plan Agent.

Part 3: Providing the Missing Information

Review the specific items checked or requested by the IRS examiner on your notice, and complete the applicable sections:

Continuing Education Deficiencies: If your CE credits were questioned, you must list the course names, dates completed, number of credit hours (distinguishing between federal tax law, tax updates, and ethics), and the official IRS Approved CE Provider Number. Attach copies of official certificates of completion from the education providers.
Examination Score Proof: If you are applying for initial enrollment, attach official Prometric score verification sheets demonstrating that you passed Parts 1, 2, and 3 of the Special Enrollment Examination within the allowable testing window.
Tax Compliance and Background Inquiries: If the IRS background check revealed tax compliance issues, attach documentation proving you filed all required federal tax returns and paid all liabilities, or provide a copy of your active, compliant IRS installment agreement.
Disciplinary or Legal Clarifications: If you answered “Yes” to questions regarding criminal convictions, professional license suspensions (such as from a state bar or accountancy board), or contempt citations, attach complete court records, administrative orders, and a written explanatory statement.

Part 4: Signature Under Penalties of Perjury

You must sign and date the bottom of Form 15115. By signing, you certify under penalties of perjury that all statements made on the form and all attached educational and legal records are true, correct, and complete. An unsigned response cannot be processed and will result in the immediate closure of your application.

8. Required Documents and Information Needed Before Filling

Before completing Form 15115, assemble the following professional and regulatory records:

The original Form 15115 notice received from the IRS Return Preparer Office.
A copy of your previously submitted Form 23, Form 8554, or Form 8554-EP.
Official Certificates of Completion for all disputed continuing education courses, verifying IRS provider numbers and ethics credits.
Official Prometric score reports for all three parts of the Special Enrollment Examination (for new applicants).
IRS tax transcripts, account statements, or payment confirmation receipts proving your personal and business tax compliance.
Certified court dockets or licensing board orders (if responding to character or disciplinary inquiries).

9. Common Mistakes to Avoid

Failing to handle Form 15115 properly can derail your professional tax practice. Avoid these frequent mistakes:

Submitting Non-Approved Continuing Education: The IRS strictly mandates that continuing education hours must be earned through IRS-Approved Continuing Education Providers. Courses taken through unapproved vendors or non-tax professional seminars will be rejected.
Ignoring Personal Tax Compliance Issues: Circular 230 requires practitioners to practice what they preach. If you have unfiled tax returns or unpaid personal tax liabilities without an active installment agreement, the IRS will not grant or renew your enrollment card until those liabilities are fully resolved.
Missing the Response Window: Failing to submit Form 15115 within the designated 30- to 60-day window results in an administrative denial of your application and the forfeiture of your application fee.
Sending Duplicate User Fees: Form 15115 is an information request, not a fee demand. Unless your letter explicitly states that your initial electronic payment on Pay.gov failed, do not submit another payment check.
Mailing Records Without Form 15115: Sending loose CE certificates or tax returns without attaching Form 15115 will cause your records to be misrouted or lost in general IRS mailrooms.

10. Penalties for Non-Filing or Errors

Because Form 15115 is a professional licensing document, failing to comply carries severe professional and regulatory consequences rather than civil tax fines:

Application Rejection and Fee Forfeiture: If you ignore Form 15115, the IRS will officially reject your application, closing the file and retaining your non-refundable user fee.
Loss of Practice Privileges (Inactive Status): If an existing Enrolled Agent’s renewal is rejected or abandoned, their enrollment status is changed to “Inactive.” Under Circular 230, an individual in inactive status is strictly prohibited from representing taxpayers before the IRS.
Inability to File Form 2848: The IRS Centralized Authorization File (CAF) unit regularly checks active EA databases. If your enrollment lapses, the IRS will reject newly submitted Forms 2848 (Power of Attorney), locking you out of ongoing client audits and collection cases.
Office of Professional Responsibility (OPR) Discipline: Intentionally providing fraudulent CE certificates or falsifying suitability disclosures constitutes a severe violation of Circular 230 Section 10.51, exposing the individual to permanent disbarment from practice before the IRS and criminal prosecution under 18 U.S.C. Section 1001.

12. Frequently Asked Questions (FAQs)

1. What is the difference between Form 23, Form 8554, and Form 15115?

Form 23 is the initial application to become an Enrolled Agent. Form 8554 is the application used every three years to renew an existing Enrolled Agent credential. Form 15115 is an inquiry notice sent by the IRS when either Form 23 or Form 8554 is missing required information or documentation.

2. What are the continuing education requirements for renewing an Enrolled Agent license?

Under Circular 230, an Enrolled Agent must complete a minimum of 72 hours of continuing education credits during each three-year enrollment cycle. This must include at least 16 hours of CE each calendar year, with a minimum of 2 hours dedicated to federal tax ethics annually.

3. Can I continue representing clients before the IRS while Form 15115 is pending?

If you are an existing Enrolled Agent and your current three-year enrollment cycle has not yet expired, your practice rights remain active while you cure deficiencies on Form 15115. However, if your renewal cycle deadline has passed and your application has not been approved, your credential may lapse into inactive status, suspending your representation privileges.

4. What does an IRS “suitability check” involve for an Enrolled Agent?

Before issuing or renewing an enrollment card, the IRS conducts an automated background review to confirm that the practitioner has filed all required personal and business federal tax returns and paid all tax liabilities. A history of unfiled returns or unresolved tax debt can result in denial of enrollment.

5. What happens if I lost a continuing education certificate requested on Form 15115?

You must contact the IRS-approved CE provider who sponsored the course and request a duplicate certificate of completion. You can also log into your online PTIN account to review your reported CE credit history, which tracks courses reported by approved providers.

6. Can I submit Form 15115 online?

Currently, Form 15115 is submitted primarily by secure fax or by mail directly to the IRS Return Preparer Office, as indicated on your notice. There is no automated self-service portal to submit Form 15115 through retail software.

13. Conclusion: Key Takeaways

IRS Form 15115 is an essential administrative safeguard that protects your professional standing as a federally authorized tax practitioner. When the IRS Return Preparer Office identifies missing CE hours, unverified exam scores, or suitability issues on your enrollment or renewal application, Form 15115 provides a structured opportunity to cure those defects and preserve your credentials.

Because failing to respond within the designated 30- to 60-day window can result in application rejection, fee forfeiture, and the immediate suspension of your right to represent clients under Circular 230, tax practitioners should compile the requested CE certificates or tax records immediately and submit Form 15115 via secure fax or certified mail.
