  1. How to register a business in Ohio

    Sole proprietors under their own name file nothing with Ohio to exist — a DBA if you use a trade name, plus local licenses. To register an LLC or corporation you file formation paperwork with the Ohio business filing office (about $99, 3–7 business days online), then get a free EIN and register for state taxes.

  2. Pick a structure (sole proprietor or LLC)

    Most Ohio owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $99, and formation typically takes about 3–7 business days online. Confirm the current fee on the state site before you pay.

  3. Name a registered agent

    If you form an LLC or corporation, Ohio needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.

  4. Get your EIN from the IRS

    An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.

  5. Register for Ohio taxes

    Ohio has a state sales/use tax and has a state income tax. Ohio LLCs have no annual report. The Commercial Activity Tax (CAT) now only applies above $6M in Ohio gross receipts (the exclusion was raised from $150k to $3M in 2024 and $6M in 2025), so roughly 90% of Ohio businesses no longer file it.

  6. Confirm local licenses and permits

    Ohio rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.

  7. Open a business bank account and get insurance

    Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.

  8. Put the ongoing report on your calendar

    Ohio does not require an ongoing entity report for LLCs — one less deadline to track.
