1 · The vehicle
Texas: Doc fee cap is an OCCC 'safe harbor,' not a hard legal ceiling. Private-party sales are taxed on the greater of price or 80% of the vehicle's Standard Presumptive Value — this estimate assumes a dealer purchase.
2 · Tax & fees
State base rate applied: 6.25% · trade-in reduces taxable amount
3 · Trade & financing
Estimates only. Tax rates, trade-in credit rules, and fee caps are approximations and change by locality and year — verify with your state DMV and dealer paperwork.
