Buying A Used Motor Vehicle

Effective October 1, 2006:

State law changes the method to calculate motor vehicle sales and use tax due when you buy a used vehicle. The tax will continue to be due when you title and register the vehicle at the county tax office. A purchaser must pay the tax within 30 calendar days from the date of purchase or the date the vehicle was brought into Texas for use to avoid penalties.

Estimate Tax Calculation For Buying A Used Motor Vehicle:

  • Q. How much tax is due?

    • If you buy the vehicle from a licensed dealer, the tax is 6.25% of the sales price. If you buy from a private party, such as a friend or relative, the tax is 6.25% of:
      • the sales price, if you paid 80% or more of the vehicle’s standard presumptive value (SPV);
      • 80% of the vehicle’s SPV, if you paid less than that amount; or
      • the certified appraised value, if you paid less than 80% of the vehicle’s SPV and you get a certified appraisal.

Certified Appraisal Value:

If a Certified Appraisal Value is available, the tax amount is calculated based on the Certified Appraisal Value.

Purchased Price:

The amount you paid for your used vehicle.

Standard Presumptive Value:

The tax amount is calculated based on the purchased price or 80% of the Standard Presumptive Value *, whichever is higher.

80% of the SPV:

* The vehicle's Standard Presumptive Value (SPV) can be obtained from Texas Department of Motor Vehicles website.

* VIN number and mileage are required to obtain the vehicle's SPV.

Total:
  • Q. What is the Standard Presumptive Value (SPV)?

    • The law requires the Texas Department of Motor Vehicles (TxDMV) to determine and publish a SPV data base for used vehicles. Check the TxDMV Web site at www.TxDMV.gov.
  • Q. My vehicle may be valued less than the calculated Standard Presumptive Value (SPV). Do I have an option?

    • Yes. You may obtain a certified appraisal on the Texas State Comptroller’s “Used Motor Vehicle Certified Appraisal form” (form 14-128) and submit it when you apply for title, within 30 days of the sale date. The signature on the form must be original. (no photocopy)
    • The certified appraisal form 14-128 must be completed and signed by one of the following:
      • Licensed Dealer
        Appraisal fee: $100 - $300 (cars/light trucks)
      • Licensed Insurance Adjuster
        Appraisal fee: determined by the adjuster
    • For details, please refer to the instructions on the form 14-128.
  • Q. I just bought/sold a car. How do I transfer the title?

    • The seller must sign the back of the title or front depending on if it is an out of state title. The purchaser should sign the title if the vehicle is less than 10 years old. Only the purchaser/applicant is required to sign the (form 130-U) title application.
    • You may also mail the application to:
      Ann Harris Bennett, Tax Assessor-Collector
      Attn: Title Mail Dept.
      P.O. Box 4089, Houston, Texas 77210-4089
    • If presented in person or by mail the owners photo ID is required. The ID must contain a unique identifier, expiration date, date of birth and expiration date. Proof of current insurance will be required in the new purchaser's name. If the vehicle was purchased over 30 days ago insurance must be provided in the new purchasers name on the vehicle. If the vehicle was last registered in a non-affected (attainment) county, proof of emissions-testing will be required. Please see Emissions-testing regulations.
    • Additional identification rules apply for titling a vehicle in the name of a business or organization.
    • Employees authorized to title a vehicle for leasing companies, government entities, organizations and private businesses must provide the following in addition to one of the acceptable forms of identification listed under the Forms of Identification tab:
      • A letter of authorization on the employer’s official letterhead, or
      • An official business card with the employer and employee’s name
    • The title fee is $33, plus motor-vehicle sales tax (6.25 percent). There is also a $2.50 transfer of a current registration fee. If the license is not current, there may be a registration fee. Please note sales tax is paid on the actual price or 80% of the Standard Presumptive Value -- whichever is the higher amount.
      SPV values can be found on the Texas Department of Motor Vehicles website .
    • When you purchase a vehicle from a licensed Texas dealer located in Harris County, the dealer is required to complete all the paperwork necessary and file the documents with the Harris County Tax Office. The dealer and general public are required to file the documents with the Harris County Tax Office within 30 calendar days of the date you purchased the vehicle. Additional penalties will be collected if the paperwork is filed after the 30 calendar days.
