To become a tax preparer in Louisiana, you need federal credentials rather than a state license: a Preparer Tax Identification Number (PTIN) from the IRS, an Electronic Filing Identification Number (EFIN) if you plan to e-file for clients, and registration with the Louisiana Department of Revenue to transmit state returns. Louisiana does not require a separate state license or exam to prepare taxes for pay. Your parish or city will likely want an occupational license on top of that, but the real gatekeeping happens at the federal level.
Step One: Get a PTIN From the IRS
Every person who gets paid to prepare or help prepare a federal tax return must have a valid PTIN.1Internal Revenue Service. PTIN Requirements for Tax Return Preparers That applies whether you work for a national firm or run a seasonal practice out of your home. Without one, you cannot legally prepare returns for compensation anywhere in the country.
You apply online through the IRS website. The application asks for your Social Security number, personal details (name, address, date of birth), business information, data from a prior-year tax return to verify your identity, and disclosure of any felony convictions or unresolved issues with your own tax obligations. Those disclosures are not automatic disqualifiers; the IRS reviews them as part of a suitability determination.2Legal Information Institute (LII). Preparer Taxpayer Identification Number (PTIN)
The fee for 2026 is $18.75 and is non-refundable.3Internal Revenue Service. IRS Reminds Tax Pros to Renew PTINs for the 2026 Tax Season Most applicants who apply online receive their PTIN number immediately after submitting the form.
Step Two: Get an EFIN if You’ll E-File
Louisiana effectively pushes serious preparers toward electronic filing, so you’ll likely need an EFIN. This is a separate credential from your PTIN and involves a more thorough vetting process.4Internal Revenue Service. Become an Authorized E-File Provider
The application runs in three stages. First, create an e-services account through the IRS portal. Second, complete the e-file application, where you’ll enter identification information for your firm, provide details for each principal and responsible official, and select “Electronic Return Originator” as your provider type; the system saves your progress if you need to return to it. Third, pass a suitability check that includes a credit check, tax compliance review, criminal background check, and review of any prior e-file violations.
One requirement catches many first-time applicants off guard. If you are not a CPA, attorney, or enrolled agent, the IRS requires you to submit fingerprints through an authorized Livescan vendor. You schedule the appointment through a link on your application summary page after submitting the application. Build the timeline into your plans: the IRS can take up to 45 days from your submission date to approve the application.4Internal Revenue Service. Become an Authorized E-File Provider
Step Three: Register With the Louisiana Department of Revenue
With your federal credentials in hand, register with Louisiana’s Department of Revenue so you can transmit state returns. The state’s central portal is the Louisiana Taxpayer Access Point (LaTAP), where you manage your credentials and interact with state revenue systems.5Louisiana Department of Revenue. File and Pay Online
Create a LaTAP account if you don’t already have one, then provide your PTIN, EFIN, legal business name, physical address, and the types of taxes you intend to file for clients. The system cross-references your federal credentials, so your information needs to match exactly what you submitted to the IRS. Mismatched records are one of the most common causes of processing delays.
Step Four: Check Your Parish for a Local License
Louisiana parishes and municipalities generally require businesses to obtain a local occupational license before operating. Fees and timing vary by jurisdiction, and some parishes require you to secure the license before you open your doors. Call your parish or municipal government and confirm what applies at your address before you take on your first client.
Why the EFIN Step Isn’t Really Optional
Louisiana law gives the secretary of the Department of Revenue authority to require electronic filing of tax returns.6Justia. Louisiana Revised Statutes 47:1520 – Electronically Filed Returns; Signatures The mandate works on a volume threshold: any preparer who files more than 100 Louisiana individual income tax returns in a calendar year must electronically file at least 90% of returns the following year.7Louisiana Department of Revenue. Requirement for Tax Preparers to File Income Tax Returns Electronically
Even if you don’t expect to hit 100 returns in your first year, setting up your e-filing credentials early saves scrambling later. If your practice grows past the threshold, you’re expected to be ready the next filing season.
What a PTIN Lets You Do — and What It Doesn’t
Holding a PTIN lets you prepare and sign returns for pay. It does not let you represent clients before the IRS in audits, collections, or appeals. If a client gets an audit notice, you can’t speak to the IRS on their behalf; you can only refer them to someone who can.8Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications
Three categories of tax professionals have unlimited representation rights: enrolled agents, CPAs, and attorneys. They can represent any client on any matter before the IRS. Pursuing one of those credentials is a substantially bigger commitment than getting a PTIN.
There is a middle path. Preparers who complete the IRS Annual Filing Season Program earn limited representation rights. With that credential you can represent clients before revenue agents and customer service representatives, but only on returns you personally prepared and signed. You still cannot handle appeals or collection matters, and you cannot represent clients whose returns you didn’t prepare.8Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications
Keeping Your Credentials Active Each Year
Your PTIN expires on December 31 every year. Renewal season opens in mid-October, and you need to renew before year-end to have a valid PTIN for the upcoming filing season.9Internal Revenue Service. Frequently Asked Questions: PTIN Application/Renewal Assistance The renewal fee is $18.75, and the online process takes about 15 minutes.3Internal Revenue Service. IRS Reminds Tax Pros to Renew PTINs for the 2026 Tax Season If you let it lapse, any returns you prepare during that period are invalid, and client filings can be rejected.
Keep your LaTAP registration current too. Business structure changes, address changes, and e-filing status changes need to flow through to the Department of Revenue promptly, or you risk rejected transmissions in the middle of filing season.
The Annual Filing Season Program
The IRS offers a voluntary continuing education program for non-credentialed preparers. Completing it earns you an Annual Filing Season Program Record of Completion and the limited representation rights described above. The program requires 18 hours of continuing education each year:10Internal Revenue Service. General Requirements for the Annual Filing Season Program Record of Completion
- 6 hours covering an Annual Federal Tax Refresher course on current-year law changes, with a comprehension test at the end
- 10 hours on federal tax law topics of your choice
- 2 hours of ethics
Preparers who previously passed the Registered Tax Return Preparer test or certain other recognized exams can skip the six-hour refresher and need only 15 hours total.11Internal Revenue Service. Annual Filing Season Program
Your Own Tax Compliance
The IRS monitors your personal tax compliance as a condition of keeping your credentials. A standard compliance check reviews up to four years of your tax records, or five if a fraud-related penalty was assessed, examining whether you’ve filed on time, paid on time, and have no outstanding liabilities.12Internal Revenue Service. Standard Tax Compliance Checks for Suitability and Monitoring Compliance problems can put your PTIN and EFIN at risk.
Due Diligence Rules You Need to Know Before You Start
Federal law imposes specific due diligence obligations on preparers who file returns claiming certain tax credits or the head-of-household filing status. The credits covered include the Earned Income Tax Credit, Child Tax Credit, Additional Child Tax Credit, Credit for Other Dependents, and American Opportunity Tax Credit. For returns filed in 2026, the penalty for each due diligence failure is $650 per credit or filing status claimed, so a single return claiming all four categories could cost you up to $2,600 in penalties if you didn’t do the required work.13Internal Revenue Service. Consequences of Not Meeting the Due Diligence Requirements
In practice, due diligence means asking the right questions, documenting the answers, and not accepting whatever a client tells you at face value. The penalties add up quickly across a client base.
What Happens When Preparers Cross the Line
Louisiana treats fraudulent tax preparation as a serious matter. The Department of Revenue can investigate preparers who engage in fraudulent activity or conduct that interferes with proper tax administration. If the secretary determines a preparer is creating an immediate threat to taxpayers, the department can issue a cease-and-desist order. Ignoring that order triggers a penalty of $25 per return for each violation.14FindLaw. Louisiana Revised Statutes Tit. 47, 1574.2
Courts can also permanently bar someone from acting as a tax preparer in Louisiana. The order typically prohibits the person from directly or indirectly preparing, assisting with, or directing the filing of any Louisiana tax return for anyone other than themselves.15Louisiana Department of Revenue. Barred From Preparing The Department of Revenue publishes a list of barred preparers, so the consequences are visible to anyone who checks.
