How each state structures it
Colorado
Colorado's vehicle tax structure is dominated by the Specific Ownership Tax (SOT) — an annual depreciating tax that replaces traditional vehicle property tax. SOT is based on 85% of the original MSRP (not what you paid, not the current value) with rates that drop sharply each year: 2.10% year 1, 1.50% year 2, 1.20% year 3, 0.90% year 4, 0.45% years 5-9, then a flat ~$3 minimum from year 10 onward. The state sales tax is the lowest in the US at 2.9%, but local rates can push combined rates to 8.85% in Denver and Boulder. EVs pay about $73/year (decal fee + road usage equalization, both rising annually) but qualify for a state tax credit of up to $5,000 on new purchases (through 2026). A new $35,000 vehicle in Denver runs about $3,260 in first-year costs, with annual renewals around $720 dropping fast to about $200/year by year 5.
New Mexico
New Mexico has one of the lowest vehicle tax burdens in the US: the Motor Vehicle Excise Tax (MVET) is just 4% of purchase price (replacing sales tax), trade-in is fully credited, and there's NO local additions. There's no annual ad valorem on vehicles, and no EV surcharge. Registration is weight + age tiered, typically $45/year for a passenger vehicle (vehicles 5+ years old get 20% off). Title fee is only $5 plus a $2 admin fee. New Mexico also offers up to $3,000 EV state tax credit through 2030. A new $35,000 vehicle in New Mexico runs about $1,452 in first-year costs — among the cheapest in the US for total vehicle ownership cost in the first year — with annual renewals just $45.
What this means for you
- Buying a new car: New Mexico is roughly $1,866 cheaper than Colorado in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: New Mexico is cheaper to renew annually by about $497/year. Over a 5-year ownership period that's roughly $2,486 in renewal-fee savings alone.
- If you drive an EV: New Mexico has no EV surcharge while Colorado adds $73/year — a meaningful long-term cost advantage for New Mexico EV owners.
- Structural differences: Neither state imposes an annual ad valorem vehicle property tax, so renewal costs stay relatively flat after the first year for both.
