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.

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.Suggested Episode Timestamps00:21: Why this episode gets practical00:32: Step 1: Get your PTIN00:57: Step 2: Apply for your EFIN1:31: Step 3: Check your state tax preparer requirements2:02: Step 4: Form your business entity2:35: Step 5: Get errors and omissions insurance3:00: Step 6: Use an engagement letter3:29: The six-part legal foundation3:42: How MuseSpring helps with the implementation4:08: Preview of the next episodeResources MentionedMuseSpring: https://musespring.comTax Business Blueprint Program: https://musespring.comThe Law Office of Jason Carr, PLLC: https://carrtaxlaw.com
