Buying a car in Texas means transferring the title and registering the vehicle at your county tax assessor-collector’s office within 30 days of the sale, paying the state’s 6.25 percent motor vehicle sales tax, and showing proof of liability insurance that meets Texas minimums. Miss the 30-day window on a private-party purchase and the penalties start the next day. Buy from a dealer and most of the paperwork gets handled for you, but the money and the deadlines still belong to you.
What to Bring to the County Tax Office
For a private-party purchase, you need five things in hand before you walk into the tax office:
- A completed Form 130-U, the Application for Texas Title and/or Registration, with the VIN, odometer reading, and sales price filled in1Texas Department of Motor Vehicles. Application for Texas Title and/or Registration
- The original title, signed by the seller in the assignment section on the back and dated with the exact day of sale
- Proof of liability insurance meeting the 30/60/25 minimums
- A valid government-issued photo ID (Texas driver’s license, U.S. passport, or military ID) with a name that matches the title assignment exactly
- Payment for the sales tax, title fee, and registration fee
The title has to be clean. Any erasure, white-out, or correction in the assignment section voids the transfer, which forces the seller to apply for a duplicate before the sale can go through. Check that before you hand over money.
For a used car, run the VIN through an NMVTIS-approved provider before you buy. The National Motor Vehicle Title Information System flags salvage, flood, and junk brands and catches cases where a damaged vehicle has been re-titled in another state to hide its history.2VehicleHistory.bja.ojp.gov. For Consumers It’s one of the cheapest forms of insurance on a used-car purchase.
Insurance You Need Before You Drive
Texas requires at least $30,000 for bodily injury per person, $60,000 per accident, and $25,000 for property damage, usually called 30/60/25 coverage.3State of Texas. Texas Transportation Code 601.072 – Minimum Coverage Amounts The county tax office will not process your title transfer without proof of coverage on file, and driving without it is a separate offense with its own fines.
If you’re buying from a private seller and plan to drive the car home, call your insurer first. Most carriers can add a vehicle to an existing policy over the phone in a few minutes.
Sales Tax and the Standard Presumptive Value
Texas charges 6.25 percent sales tax on every retail vehicle sale.4State of Texas. Texas Tax Code 152.021 – Retail Sales Tax At a dealership the tax is calculated on the sales price minus any trade-in credit, and the dealer collects it as part of closing.
Private-party sales use the Standard Presumptive Value system. SPV is the state’s estimate of a vehicle’s fair market value, drawn from nationally recognized pricing guides.5Texas Comptroller of Public Accounts. Motor Vehicle Tax Guide – Standard Presumptive Value on Private-Party Transactions If you paid at least 80 percent of the SPV, tax is calculated on what you actually paid. Pay less than 80 percent, and the county calculates tax on 80 percent of the SPV instead.6State of Texas. Texas Tax Code 152.0412
Look up the SPV before you agree on a price. The TxDMV’s online calculator takes a VIN and returns the number.7Texas Comptroller of Public Accounts. Private-Party Purchases and Standard Presumptive Values If you think the SPV overstates the car’s actual condition, you can get a certified appraisal from a licensed adjuster or dealer within 20 working days of the sale and present it to the county to lower your tax basis.6State of Texas. Texas Tax Code 152.0412
The $10 Family Gift Transfer
If a close family member gives you a vehicle for no payment, the tax is a flat $10 instead of 6.25 percent. The qualifying list is broad: spouses, parents, stepparents, children, stepchildren, siblings, grandparents, in-laws, great-grandparents, great-grandchildren, and legal guardians.8Texas Comptroller of Public Accounts. Family Transfers – Motor Vehicle Tax Guide Both parties complete Form 14-317 (Affidavit of Motor Vehicle Gift Transfer) and file it with Form 130-U.
It has to be a genuine gift with no money changing hands. Pay a cousin $5,000 for a $15,000 car and it’s a sale, not a gift, and the SPV rules apply to the full transaction. The Comptroller’s office audits these.
Title, Registration, and Inspection Replacement Fees
On top of sales tax, you’ll pay a handful of smaller fees at the county window:
- Title transfer fee of $28 in most counties, $33 in counties that participate in the state emissions program9Tarrant County, TX. Title Fees and Taxes
- Annual registration of $50.75 for passenger vehicles and trucks weighing 6,000 pounds or less, plus local county fees that vary by location10Texas Department of Motor Vehicles. Fee Chart 1C
- A $7.50 annual inspection replacement fee, which took the place of the old safety inspection fee in 202511Texas Department of Public Safety. Vehicle Safety Inspection Changes Take Effect January 2025
Plan on roughly $90 to $100 in combined title and registration fees on top of your sales tax. Some counties layer on local processing charges, so calling the tax office for an exact total beats a wasted trip.
Federal law also requires an odometer disclosure as part of the transfer, usually handled on the title itself. Vehicles from model year 2010 or earlier are exempt.12eCFR. 49 CFR Part 580 – Odometer Disclosure Requirements
Buying From a Dealer: Doc Fees, Buyers Guide, and Cash Reports
Dealers charge a documentation fee for the paperwork they process on your behalf. Texas treats doc fees of $225 or less as presumptively reasonable; anything above that requires the dealer to file a cost analysis with the state justifying the charge.13Cornell Law Institute. 7 Texas Administrative Code 84.205 – Documentary Fee Texas does not cap doc fees. If a dealer quotes something well above $225, ask for an itemized breakdown.
On a used car, the Federal Trade Commission’s Used Car Rule requires every dealer to post a Buyers Guide on the window. The guide states whether the car comes with a warranty or is sold “as is” and, if there’s a warranty, which systems are covered, for how long, and what share of repairs the dealer will pay.14eCFR. 16 CFR Part 455 – Used Motor Vehicle Trade Regulation Rule The guide becomes part of the sales contract and overrides any conflicting language in the purchase agreement. Private sellers are not subject to the rule, which is why private-party buyers have to do more homework on their own.
If you pay a dealer more than $10,000 in cash (including cashier’s checks and money orders with a face value of $10,000 or less), the dealer must file IRS Form 8300 reporting the transaction. The rule applies whether the cash arrives in one payment or in installments that cross $10,000 within a year.15Internal Revenue Service. IRS Form 8300 Reference Guide The reporting duty is the dealer’s, not yours; it’s routine.
When you buy from a dealer, the dealer is required to apply for title and registration in your name and submit the paperwork, though the statute gives a “reasonable time” rather than a fixed number of days.16State of Texas. Texas Transportation Code 501.0234 – Duty of Vehicle Dealer on Sale of Certain Vehicles
Driving the Car Home: Transit Permit
Private sellers usually keep their plates. Without plates or a permit, you can’t legally drive the car off the seller’s property. The TxDMV offers a free Vehicle Transit Permit you can print at home; it’s valid for five calendar days, which is enough time to get the car home or to the tax office.17Texas Department of Motor Vehicles. Vehicle Transit Permit: Eligibility and Requirements You need the VIN and active liability insurance to generate the permit. Only one permit is issued per vehicle, and salvage or nonrepairable-branded vehicles don’t qualify.
Emissions Testing Where It Still Applies
Texas eliminated mandatory safety inspections for non-commercial vehicles on January 1, 2025.11Texas Department of Public Safety. Vehicle Safety Inspection Changes Take Effect January 2025 You no longer need to pass a brake, tire, and lighting check to register a passenger car. Emissions testing survived, though. Vehicles registered in 17 designated counties still must pass an annual emissions inspection before registration, with Bexar County joining the list in November 2026.18Texas Commission on Environmental Quality. Vehicle Emissions Inspections in Texas
The affected counties include Harris, Dallas, Tarrant, Travis, Bexar (starting November 2026), Collin, Denton, Fort Bend, Galveston, Montgomery, Williamson, El Paso, and several others around the Dallas-Fort Worth and Houston regions. That’s the reason the title transfer fee is $33 in emissions counties and $28 elsewhere.
What Happens If You Miss the 30-Day Deadline
You have 30 calendar days from the date of sale on the title assignment to file the transfer and registration at the county tax office. Active-duty military members get 60 days.19State of Texas. Texas Transportation Code 501.145 – Filing by Purchaser; Application for Transfer of Title
On day 31, a flat $25 penalty hits, with another $25 added for every month the title remains untransferred.20Texas Department of Motor Vehicles. State Law Requires Private Sale Vehicle Buyers to Title in 30 Days Neither the county nor TxDMV can waive or reduce them. Let the transfer slide for six months and you owe $150 on top of everything else. The car also stays in the seller’s name in state records in the meantime, which means they’re exposed to tolls, parking tickets, and liability from accidents involving a vehicle they no longer own. File on time.
