Why federal and state and local government
Business entities are formed and named at the state level. Federal agencies handle tax IDs and trademarks, and local governments set their own licensing and permit rules.
What to do next
- Register with the state where you do business, usually through the Secretary of State’s office or a business agency.
- Apply for a federal tax ID number, which most businesses need.
- Check with your county or city about a DBA name and any local licenses and permits.
