Do you need a license to detail cars in Texas?

By Koni · Last checked: Oct 20, 2026

We found no Texas state license just for car detailing. You still need an assumed name certificate if you trade under a brand name, a check with your city, an answer from the Comptroller on sales tax, wash water kept out of storm drains, and insurance. Official links for each step are below.

This guide is general information, not legal advice. Rules change, so check with your state and city before you open.

Texas mobile detailing checklist: assumed name, city permit, sales tax check, HOA rules, insurance

The short checklist

Assumed name certificate, if you trade under a brand name
City permit or registration where you are based
Sales tax: ask the Comptroller whether your services are taxable
Water runoff: keep wash water out of storm drains
HOA and apartment permission before you book
Liability insurance

Step 1: Register your business name

Official source: Texas Secretary of State

Texas law requires an assumed name certificate if you trade under anything other than your own legal name. Sole proprietors file with the county clerk; LLCs file with the Secretary of State and the county clerk.

Step 2: Check your city

Dallas, Fort Worth, Plano and Arlington each run their own permit office. Call the one you are based in.

Step 3: Ask the Comptroller about sales tax

Official source: Comptroller 96-259

The Comptroller’s own list of taxable services (publication 96-259, updated January 2026) sets out the 16 categories in Tax Code section 151.0101. Car washing and vehicle detailing are not named in any of them. That is not the same as a ruling for your business, so get the answer in writing from the Comptroller before you set prices.

Step 4: Water, HOAs and apartments

Keep wash water out of storm drains, and ask HOAs and apartment managers first. Rinseless methods travel better where water is restricted.

Step 5: Insurance

General liability at minimum, plus cover for customer cars in your care.

FAQ

Do I need a DBA to detail cars in Texas?

If you work under any name other than your own legal name, yes. Texas calls it an assumed name certificate. Sole proprietors file it with the county clerk in each county where they have a business office. LLCs file with both the Secretary of State and the county clerk.

Do I need an LLC to start detailing in Texas?

No. You can start as a sole proprietor and file an assumed name. An LLC can separate your personal assets from business debts and claims, which matters when you work on other people’s cars. Many detailers start simple, get insured, and form an LLC once jobs are steady.

Can I detail cars in an HOA or apartment complex?

Often yes, but the property sets the rules. Some HOAs and apartment managers limit water use, noise or work in parking lots. Ask the customer to check before you book, put a note about it in your booking form, and use rinseless methods where water is restricted.

Do I have to charge sales tax on detailing in Texas?

Ask the Texas Comptroller. Which services are taxable is set by state law, and the answer can depend on what you do. Get a written answer or use the Comptroller’s taxable services guidance before you set prices, so tax doesn’t come out of your profit later.
