The Texas auto tax calculator uses the following formulas to estimate your vehicle taxes:

Registration Fee: Based on vehicle type and county rates

Sales Tax: 6.25% of the vehicle's purchase price

The registration fee varies by vehicle type and county. The sales tax rate is currently 6.25% for most vehicles in Texas. These rates are subject to change by the Texas Comptroller of Public Accounts.

Worked Example

Let's calculate the estimated taxes for a $25,000 car purchased in Harris County (Houston area):

  1. Purchase price: $25,000
  2. Vehicle type: Car
  3. County: Harris

Calculation:

  • Registration fee for a car in Harris County: $100
  • Sales tax (6.25% of $25,000): $1,562.50
  • Total estimated taxes: $100 + $1,562.50 = $1,662.50

Your estimated total taxes would be $1,662.50 for this example.
