Ready to start a tax preparation business, but unsure what needs to happen first?

In this episode, Jason Carr gives a practical walkthrough of the legal setup for a new tax prep business. Before taking your first paid client, you need more than tax software and a business idea. You need the proper federal identifiers, state registrations where required, business structure, insurance, and client paperwork.

Jason covers:

• How to get a PTIN
• Why an EFIN matters if you plan to e-file returns
• Which states may require additional tax preparer registration
• Why most new preparers should form an LLC
• Why errors and omissions insurance should be in place before the first return
• What an engagement letter does and why every client should sign one

If you are planning to launch a tax prep business this year, this episode gives you the practical checklist to get set up professionally before tax season starts.

Key Takeaways

• Start with your PTIN: Anyone who prepares or assists in preparing federal tax returns for compensation must have a valid PTIN before preparing returns.
• The 2026 PTIN fee is $18.75: The IRS states that the fee to obtain or renew a PTIN for 2026 is $18.75, and online applications typically take about 15 minutes.
• Apply early for your EFIN: The IRS e-file application process includes submitting an application and passing a suitability check, and IRS guidance says approval can take up to 45 days from submission.
• Suitability checks are real: The IRS suitability check may include a credit check, tax compliance check, criminal background check, and review of prior non-compliance with IRS e-file requirements.
• State rules vary: Some states impose registration, licensing, education, testing, bonding, or continuing education requirements beyond federal PTIN rules. California, Maryland, New York, and Oregon are common examples.
• The business setup is part of professional credibility: Entity formation, insurance, and engagement letters help a new preparer operate like a business rather than a seasonal hobby.
