How New Mexico sales tax is worked out
New Mexico: there is no gross receipts tax on the vehicle. The buyer pays the 4% motor vehicle excise tax to the MVD at titling on the price less the trade-in, so the amount shown is an estimate and is not added to what is due now. A dealer transfer service fee is not part of the excise tax base. New Mexico's rules say not to call a charge a 'documentary fee' unless the law requires it. Type your title fee in the Title Fee box. Gross receipts tax applies to the dealer's fees. New Mexico registration fees rose 25% on 7/1/2026.
