In short
The county tax office also handles car paperwork for the state. A title proves who owns a vehicle. Registration is the yearly sticker that lets you drive it on public roads. You pass inspection first, then renew online, by mail, or in person. If you buy a car, you have 30 days to move the title into your name.
The 30-second version
- Inspect, then renew. Get the vehicle inspected, then renew registration (“Two Steps, One Sticker”).1
- Renew online with the state (TxDMV), by mail, at the tax office, or at some local stores.12
- Bought a car? Transfer the title within 30 days of the sale to avoid late fees.3
- Fees: $33 title fee, plus registration, plus 6.25% sales tax on most sales.3
Who is in charge
The state (Texas Department of Motor Vehicles) sets the rules and most fees. The county tax office does the work for residents and keeps part of some fees.1 The tax office does not set fees or inspection rules.
Renewing registration
- Inspection first. You can check online when you can inspect.1
- Online: up to 90 days before it expires, or up to 12 months after (if you have no ticket for it). A temporary permit is emailed; the sticker comes in 10–15 days.1
- By mail: send the renewal notice or VIN, a copy of your insurance, a copy of the inspection report, and payment to the Williamson County Tax Office, 1848 Texas Trail, Georgetown, TX 78626. Mail by the 15th to get it back before month’s end.12
- Neighborhood locations: some stores renew current or expired (up to 9 months) registrations.2
Renewal can be denied for no insurance, an inspection that can’t be verified, or an owner who doesn’t live in the county.1
Titles: buying, selling, gifts
- Buyer: bring the signed title, Form VTR-130-U, a photo ID, and proof of insurance. Some cars from out of state also need an emissions report.3
- Seller: sign the title and file a transfer notice (VTR-346). This protects you if the buyer never transfers the title.3
- Late transfer: after 30 days, late penalties can be added.3
- Gifts: $10 gift tax instead of sales tax, with a signed gift affidavit.3
- Title and new-resident work is done at set hours. Original, ink-signed papers are required.2
The other side (counterweight)
- Supporters of county handling say local offices make in-person help easy to reach.
- Critics say lines are long at month’s end and that online renewals and store locations should take more of the load. The office itself suggests renewing early or online to skip lines.2
- Some people object to inspection rules; those are set by the state, not the county.
Questions to ask
- Where does the tax office post its fees for titles and registration?
- How does the tax office report wait times at each office?
What you can do next
- Renew online early, or mail by the 15th.
- Sellers: file VTR-346 the day you sell.
- Check the state’s TxDMV site for current fees before you go.
