Step 1 of 4

Start with the deal price.

Use the negotiated selling price, not the monthly payment.

Texas dealer purchases

The standard path applies the 6.25% motor-vehicle tax to the entered taxable measure after a qualifying trade allowance, then adds the selected title and registration-related charges.

Private-party Standard Presumptive Value

For the private-party SPV path, the engine uses the greater of the sales price or 80% of the entered SPV. When a valid certified appraisal is entered, it uses the greater of the price or appraisal instead.

Special Texas paths

New-resident, qualifying gift and even-exchange modes use their separate fixed tax amounts. County, inspection and other charges remain visible user-entered items.

Source and method note

The calculator distinguishes official fixed rules from local or user-entered estimates. Dealer worksheets and licensing-office totals remain the final transaction records.
