Auto Sales Tax Calculator

📊 key factors in auto sales tax (worldwide & USA standards)

Sales tax on vehicles isn’t one‑size‑fits‑all. In the US, most states apply tax to the purchase price minus trade‑in (if elected). Elsewhere, VAT or GST may apply on full value. Below we break down rates, deductions, and real‑world examples.

• trade‑in treatment: 28 US states allow full trade‑in deduction from taxable amount (e.g. California, Texas). Others tax full price.
• rebate handling: some states tax after rebates, some before — our checkboxes let you simulate both.
• global snapshot: VAT in Europe (19‑25%) vs. sales tax in Canada (5‑15%) vs. no sales tax in some GCC countries.
