State support is explicit
Texas is calculated; other states route to official services
Vehicle tax bases, trade treatment, rebates, private sales and registration methods differ. A state is added only after its transaction rules and examples are checked.
| State | Current support | Next step |
|---|---|---|
| Texas | Dealer and private-party motor-vehicle sales tax | Use the Texas calculator |
| California | Official registration estimator route | Open California DMV |
| New York | Official fee guidance route | Open New York DMV |
| Other states | No tax or fee estimate yet | Find the state agency |
