If you get paid to prepare federal tax returns, the paid tax return preparer rules require you to register with the IRS for a Preparer Tax Identification Number (PTIN), sign every return you work on, hand the client a copy, keep your own records, meet special due-diligence steps for certain credits, and follow accuracy standards that carry escalating penalties when you fall short. The rules reach further than many new preparers expect. They apply whether you sign the return or not, whether you work full time or seasonally, and whether you are paid in cash, trade, or discounted services.
Who Counts as a Paid Preparer
Federal regulations define a paid tax return preparer as anyone who receives compensation for preparing all or a substantial portion of a federal return or refund claim.1eCFR. 26 CFR 301.7701-15 – Tax Return Preparer Compensation is not limited to cash. Bartering, reduced fees on other services, or any economic benefit can qualify.
Whether the part you touched is “substantial” turns on two things: the size and complexity of the item compared to the taxpayer’s gross income, and how much of the total tax is attributable to that item.1eCFR. 26 CFR 301.7701-15 – Tax Return Preparer A Schedule C for a sole proprietor almost always crosses the line. A minor informational entry that doesn’t move the tax typically doesn’t.
Safe Harbor for Non-Signing Preparers
If you advise on a tax issue but don’t sign the return, a separate safe harbor applies. Your work isn’t a substantial portion if the amounts involved are less than $10,000, or less than $400,000 and also less than 20 percent of the taxpayer’s gross income (or adjusted gross income for individuals).1eCFR. 26 CFR 301.7701-15 – Tax Return Preparer Multiple entries get added together before you apply the test. The safe harbor doesn’t cover the signing preparer, who takes primary responsibility for the return.
Who Does Not Count
A few groups help with returns without becoming paid preparers. Volunteers in the Volunteer Income Tax Assistance and Tax Counseling for the Elderly programs are excluded, even when they receive small stipends or mileage reimbursements. Employees whose regular duties include preparing their employer’s return are not paid preparers for that work. Executors, administrators, and other fiduciaries who file for an estate or trust as part of their legal role are also excluded.
One more boundary is worth stating plainly. Anyone who prepares or helps prepare a substantial part of a return needs a PTIN regardless of whether they sign it. If you own a firm and review every return your staff produces, those staff members still need their own PTINs. Employees limited to data entry, assembling documents, or gathering receipts — without making decisions that affect the tax calculation — do not.2Internal Revenue Service. Frequently Asked Questions: Do I Need a PTIN?
Getting and Renewing Your PTIN
You apply through the IRS Tax Professional PTIN System online or by mailing Form W-12. Online is faster; most first-time applicants get their number within about 15 minutes, while paper applications take roughly six weeks.3Internal Revenue Service. PTIN Requirements for Tax Return Preparers
To apply you’ll need your Social Security Number, date of birth, mailing address, business name and address, and a credit or debit card for the fee. A copy of your most recent individual tax return helps with identity verification.4IRS.gov. Instructions for Form W-12 (Rev. 10-2025) The application asks about professional credentials, felony convictions, and whether you’re current on your own taxes. Misrepresentations can lead to denial.
The fee for a new PTIN or renewal is $18.75 for 2026, and it’s non-refundable.3Internal Revenue Service. PTIN Requirements for Tax Return Preparers Every PTIN expires on December 31, so renewal is annual. Renewals for 2026 opened on October 16, 2025.5Internal Revenue Service. Treasury, IRS Issue Regulations to Reduce the Amount of the User Fee for Tax Professionals Who Apply for or Renew a PTIN You need a valid 2026 PTIN before you prepare any returns for that year.
Signing, Copies, and Recordkeeping
Every paid preparer must complete the “Paid Preparer Use Only” section of the return, which requires a signature and the preparer’s PTIN. You must also give the taxpayer a completed copy of the return no later than the time you present it for their signature.6Office of the Law Revision Counsel. 26 U.S. Code 6107 – Tax Return Preparer Must Furnish Copy of Return to Taxpayer and Must Retain a Copy or List
For returns filed in 2026, failing to sign the return, failing to include your PTIN, or failing to give the taxpayer a copy each carries a penalty of $65 per occurrence, capped at $32,500 per category per calendar year.7IRS.gov. Revenue Procedure 2024-40 These penalties apply unless the failure was due to reasonable cause and not willful neglect.8Office of the Law Revision Counsel. 26 USC 6695 – Other Assessable Penalties With Respect to the Preparation of Tax Returns for Other Persons
You also have to keep your own records. Federal law requires you to retain either a completed copy of each return or a list showing the taxpayer’s name, identification number, taxable year, and return type.6Office of the Law Revision Counsel. 26 U.S. Code 6107 – Tax Return Preparer Must Furnish Copy of Return to Taxpayer and Must Retain a Copy or List Those records must be available for IRS inspection for three years after the close of the return period.9eCFR. 26 CFR 1.6107-1 – Tax Return Preparer Must Furnish Copy of Return or Claim for Refund to Taxpayer and Must Retain a Copy or Record
The Electronic Filing Mandate
If you reasonably expect to prepare and file 11 or more individual, estate, or trust income tax returns in a calendar year, the IRS treats you as a “specified tax return preparer” and requires you to file those returns electronically.10Internal Revenue Service. E-file Requirements for Specified Tax Return Preparers Preparers who reasonably expect 10 or fewer covered returns are exempt.
Due Diligence for Refundable Credits
When a return claims certain credits or head-of-household status, you take on extra duties. You must complete Form 8867, the Paid Preparer’s Due Diligence Checklist, and meet knowledge, documentation, and record-retention requirements for each of the following:
- Earned Income Credit
- Child Tax Credit and Additional Child Tax Credit
- Credit for Other Dependents
- American Opportunity Tax Credit
- Head of Household filing status
These items are listed on Form 8867 itself.11Internal Revenue Service. About Form 8867, Paid Preparer’s Due Diligence Checklist For returns filed in 2026, the penalty for failing due diligence is $650 per credit or filing status, per return. A single return that claims all four credit categories plus head-of-household can generate up to $2,600 in due-diligence penalties.12Internal Revenue Service. News and Updates for Paid Preparers
Penalties for Understating Tax
The larger financial exposure comes when a return understates the taxpayer’s actual bill. Federal law creates two tiers based on the preparer’s conduct.
The first tier covers unreasonable positions. If you prepare a return that understates tax because of a position you knew or should have known was unreasonable, the penalty is the greater of $1,000 or 50 percent of the income you earned from that return.13Office of the Law Revision Counsel. 26 USC 6694 – Understatement of Taxpayer’s Liability by Tax Return Preparer
The second tier covers willful or reckless conduct. If the understatement comes from intentional wrongdoing or reckless disregard of the rules, the penalty rises to the greater of $5,000 or 75 percent of your income from that return. Any amount already paid under the first tier is credited against this larger penalty.13Office of the Law Revision Counsel. 26 USC 6694 – Understatement of Taxpayer’s Liability by Tax Return Preparer
Circular 230 Sanctions for Credentialed Practitioners
CPAs, attorneys, enrolled agents, and other practitioners authorized to practice before the IRS are also subject to Treasury Department Circular No. 230. After a hearing, the IRS Office of Professional Responsibility can impose three levels of discipline: censure, a public reprimand that goes on the practitioner’s record; suspension, a temporary bar for a set period; or disbarment, a permanent bar unless the practitioner later receives specific authorization to return.
These sanctions can follow incompetence, disreputable conduct, failure to follow Circular 230 regulations, or willfully misleading a client.14IRS.gov. Treasury Department Circular No. 230 – Regulations Governing Practice Before the Internal Revenue Service After a censure or suspension, future work may carry additional conditions designed to prevent repeat violations.
The AFSP Path for Non-Credentialed Preparers
If you aren’t a CPA, attorney, or enrolled agent, the IRS offers a voluntary track called the Annual Filing Season Program. Participants complete 18 hours of continuing education each year, including a six-hour federal tax law refresher course with a test.15Internal Revenue Service. Annual Filing Season Program In exchange you earn limited representation rights: the ability to represent clients whose returns you prepared and signed before revenue agents, customer service representatives, and the Taxpayer Advocate Service.
Non-credentialed PTIN holders who don’t complete the AFSP can still prepare returns for compensation. They cannot represent clients before the IRS at all for returns prepared and signed after December 31, 2015.15Internal Revenue Service. Annual Filing Season Program For preparers without a credential, the AFSP is the only route to any representation authority.
