Worked Out-the-Door Price Example (Texas)

Purchase Scenario: Purchasing a $32,000 vehicle in Texas with an $8,000 trade-in credit and $3,000 cash down payment under the uniform 6.25% Texas Motor Vehicle Sales Tax.

Calculation: Taxable sales base = $32,000 - $8,000 = $24,000. Texas vehicle sales tax = Math.round($24,000 × 0.0625) = $1,500. Trade-in tax savings = Math.round($8,000 × 0.0625) = $500. Texas DMV title fee ($33) + annual registration tag ($51.75) = $84.75. Dealer doc fee = $150 (state regulatory benchmark). Total Out-the-Door Price = $32,000 + $1,500 + $84.75 + $150 = $33,735. Net balance to finance = $33,735 - $8,000 - $3,000 = $22,735.

What the Result Means: Texas motor vehicle tax applies at a flat 6.25% statewide with no city additions. Crediting your $8,000 trade-in lowers the taxable balance to $24,000, creating an exact $500 sales tax savings. Modest state DMV and dealer fees total under $235.
