Frequently asked questions

Private-party purchase — is the tax on what I paid?

Often not: several states tax the greater of the price or a book/standard value (Texas presumptive value, Delaware NADA, Vermont J.D. Power). The calculator uses your price; the agency may not.

Why is my dealer's total higher?

Because local taxes add on top of the state figure shown here — the dealer collects the combined rate for your address.

Do I pay again when I move states?

Usually a credit for tax paid to the first state, or a reduced new-resident rate (Georgia charges 3% TAVT to newcomers) — the destination state's rules are on its page.

Sources & verification. State DMV / revenue department publications (researched 4 November 2026; each page links its official source). Floors are labelled floors — local taxes add on top. An estimator for a typical purchase; private-party valuation rules (standard presumptive value, NADA/J.D. Power) can change the base.
