PTIN, EFIN, and the Enrolled Agent Exam: Registrations Every Tax Preparer Needs
Starting a paid tax preparation practice requires completing several federal and potentially state registrations before you prepare your first return. The PTIN (Preparer Tax Identification Number) and EFIN (Electronic Filing Identification Number) are federal requirements administered by the IRS — both are free but involve distinct application processes. On top of that, four states mandate their own preparer registration programs, and the Enrolled Agent credential — while not required — is the single most valuable investment a serious independent preparer can make. This guide walks through every registration in the order you should complete them.

Step One: Get Your PTIN (Free, Required for All Paid Preparers)
A PTIN is mandatory for anyone who is paid to prepare or assist in preparing a federal tax return. It replaces your Social Security Number on returns you prepare, protecting you from identity theft. Getting a PTIN is free and takes about 15 minutes at the IRS PTIN online system (irs.gov/ptin). You will need your Social Security Number, personal mailing address, business information if applicable, and prior-year tax return information for identity verification. PTINs must be renewed annually between October 16 and December 31 for the following filing season. Renewal is also free. You cannot legally prepare a paid return without a PTIN — IRS penalties for PTIN non-compliance run $500 per return plus potential criminal referral for willful violations.
Step Two: Apply for Your EFIN (Free, Required for E-Filing)
An EFIN (Electronic Filing Identification Number) authorizes you to electronically file returns through IRS e-file. Since e-filing is effectively mandatory (the IRS mandates e-filing for preparers who file 11 or more returns per year, and virtually all clients expect e-filed returns), you need an EFIN before your first season. The EFIN application is submitted through the IRS e-Services portal at irs.gov and requires identity verification, a fingerprint-based background check (conducted through an IRS-authorized fingerprinting service), and a suitability check. The process takes 45–60 days from application to approval. Apply no later than October to ensure you have your EFIN before January. Each physical office location or virtual filing operation needs its own EFIN — you cannot share EFINs between businesses or locations.
The Enrolled Agent Exam: The SEE and What It Covers
The Special Enrollment Examination (SEE) is the three-part IRS exam for Enrolled Agent licensure. Part 1 covers individual taxation (Form 1040 and related schedules). Part 2 covers business taxation (entities, partnerships, corporations, S-corps, estates, and trusts). Part 3 covers representation, practice, and procedures (Circular 230, IRS audit process, collection, and appeals). Each part costs $185 and is administered by Prometric testing centers nationwide on a year-round schedule. Most candidates pass in 6–18 months studying part-time. The EA credential allows unlimited representation of clients before the IRS in audits, appeals, and collections — the most powerful representation right available to a non-attorney tax professional. Annual renewal requires 72 hours of continuing education over three years (minimum 16 hours per year, including 2 hours of ethics).
State Registration Requirements: California, New York, Oregon, Maryland
Four states impose independent registration requirements on paid tax preparers beyond the federal PTIN. California requires all paid preparers who are not CPAs, attorneys, or EAs to register with the California Tax Education Council (CTEC). CTEC registration requires 60 hours of qualifying education from an approved provider, a $33 annual registration fee, and a $5,000 surety bond. Oregon issues a Licensed Tax Preparer (LTP) or Licensed Tax Consultant (LTC) license administered by the Oregon Board of Tax Practitioners — requires 80 hours of initial education and a licensing exam. Maryland requires tax preparers to register with the Comptroller's office and complete a background check. New York requires tax preparers to register annually with the Department of Taxation and Finance. Operating in these states without the required registration subjects preparers to fines and cease-and-desist orders.
LLC Formation for Your Tax Practice
Most independent tax preparers operate as sole proprietors their first season and subsequently form an LLC for liability protection. An LLC prevents business liabilities (client lawsuits, IRS penalties assessed against the practice) from reaching your personal assets. Formation costs vary by state — Wyoming and New Mexico offer the most affordable LLC structures at $100 or less in state fees, but if you practice primarily in a single state, form the LLC in that state to avoid foreign qualification fees. Most tax preparers elect S-corporation taxation through the LLC once net profit exceeds approximately $40,000 per year, allowing them to pay themselves a reasonable salary and take remaining profit as a distribution that avoids self-employment tax. Consult a CPA or tax attorney before making the S-election.
Registration Timeline for a First-Season Launch
Here is the recommended sequence: July — Apply for PTIN (15 minutes, immediate approval). August — Submit EFIN application through IRS e-Services; schedule fingerprinting appointment. September — Begin CTEC or state registration process if applicable. October — Confirm EFIN approval; begin EA exam registration if pursuing credential. November — Purchase professional tax software (Drake, ProSeries, or CrossLink); complete software training. December — Confirm all registrations are active; set up client intake workflow and document portal. January — Begin accepting clients. This 6-month runway eliminates the most common first-season failure mode: attempting to complete registrations in December and missing the January rush.

FREQUENTLY ASKED QUESTIONS
Can I prepare tax returns before my EFIN is approved if I already have a PTIN?
You can prepare returns with a PTIN before your EFIN is approved, but you cannot e-file them yourself. You would need to use a third-party transmitter or an ERO (Electronic Return Originator) to submit returns electronically. In practice, most preparers wait for their own EFIN before accepting clients, as the turnaround time is 45–60 days.
Does the EA designation expire?
No, the EA designation does not expire, but it requires renewal every three years through IRS Form 8554. Renewal requires 72 hours of IRS-approved continuing education (including 2 hours of ethics annually) and payment of a renewal fee. Failure to complete CE requirements results in inactive EA status.
Is a business license required to start a tax prep practice?
Most cities and counties require a general business license (typically $50–$150 per year) for any commercial activity, including home-based businesses. This is separate from the PTIN, EFIN, and any state preparer registration. Check your local municipal clerk's office for business license requirements before you begin operations.
What happens if I prepare returns without a PTIN?
Preparing paid returns without a PTIN is a federal violation. IRS penalties include $500 per return prepared without a PTIN, and willful violations can result in referral for criminal prosecution under 26 U.S.C. § 7407. The IRS actively audits preparer compliance and cross-references returns filed by unregistered preparers.
