New Mexico: Motor Vehicle Excise Tax — no local option taxes apply (those attach to gross receipts, not the MVET). Private-party sales declared under 80% of book value are taxed on book value instead.

New Mexico charges a 4% Motor Vehicle Excise Tax at titling instead of ordinary sales tax — and because it's a separate excise, the gross receipts tax add-ons that inflate everyday purchases in New Mexico don't pile onto your car. A flat 4% statewide is among the gentlest true vehicle tax rates in the country, and the trade-in credit applies in full against it.

The excise is collected when you title the vehicle at the MVD, which matters most on private-party purchases: the handshake price isn't the finished price, and the 4% comes due at the counter. On dealer purchases it's folded into the paperwork like anywhere else.

Doc fees are uncapped, typically $300–450 — modest by uncapped-state standards. With a low flat rate, full trade credit, and no local stacking, New Mexico's out-the-door math is short and honest: price minus trade, times 1.04, plus title, registration, and the doc fee. If the dealer's total wanders meaningfully above that, something extra found its way onto the sheet.

Every figure above was last verified against official New Mexico sources in August 2026. Tax rules do change — the final word is always your paperwork and the DMV.
