How to start a auto repair shop in Arizona (2026)
Everything a new auto repair shop in Arizona needs in the first months: registration, licenses, taxes, insurance and the yearly deadlines, with official links.
1. Register your business
Most owners form an LLC with the Arizona Corporation Commission. Once it's registered, find it here to claim a free website and see your exact dates.
2. Licenses
Arizona doesn't require a statewide shop registration. Your city still needs a business license and zoning approval for a shop, and you'll need a plan for used oil and other waste.
Your city or county may also require a general business license or tax receipt.
3. Taxes

If you expect to owe $1,000 or more in federal tax for the year, you pay estimated tax four times a year.
