File an LLC yourself or use a service? (2026)

Filing yourself is fine for a simple LLC. This is the whole job, so you can compare it with a price.

1. Check the name on your state’s business search.
2. File the formation document with the Secretary of State. The fee runs $35 to $500 by state.
3. Name a registered agent with a street address in the state (yourself in 7 states that allow it).
4. Apply for the EIN with the IRS, free.
5. Write an operating agreement if there is more than one owner.
6. Calendar the report. 6 states have none; the rest charge $7 or more.

Mainstay Filing, our pick, does steps 2 to 4 and the report for $199 a year plus the state fee. Choose it if you want one price that does not rise; file yourself if you only need the filing. Pick a state to see the numbers: all 50 states.
