Overview
Below that sits Colorado's real quirk: registration isn't one number, it's seven or eight little line items - a weight-based base fee, a Road Safety Surcharge, a Bridge Safety Surcharge, a clerk hire fee, an EMS fee, an insurance-database fee, and a POST fee - each set by a different statute and each collected at your county office, not a state DMV window. The calculator below runs every line for your purchase, vehicle age, and address.

02 - Step by step
How to pay Colorado TTL
- 1
Get the signed-over title (or dealer paperwork) and a bill of sale showing the price.
- 2
Find your original MSRP if the vehicle is newer than 10 years - your county needs it to set the Specific Ownership Tax.
- 3
Bring the title, proof of Colorado insurance, and ID to your county motor vehicle office within 60 days of the sale.
- 4
The clerk calculates sales tax on your district's rate, adds the Specific Ownership Tax for the vehicle's age, and totals the registration stack.
- 5
Pay everything in one transaction; plates and a registration card are issued the same visit in most counties.

Colorado tax, title & license FAQ
How much is tax, title and license on a $34,000 car in Colorado?
Roughly $3,780 in Denver: about $3,111 in sales tax (9.15%), around $607 in first-year Specific Ownership Tax, the $7.20 title fee, and about $55 in base registration and safety surcharges for a midsize vehicle. Move to a lower-tax district and the sales-tax piece drops sharply - that's the biggest lever in Colorado.
Why is there a second tax on top of sales tax?
That's the Specific Ownership Tax - Colorado's version of a personal property tax on vehicles, paid every year at registration, not just at purchase. It's calculated from 85% of the car's original MSRP and a rate that drops from 2.1% in year one to a flat $3 once the vehicle turns 10.
Does Colorado tax the full purchase price on a trade-in?
No - at a licensed dealer, sales tax applies to price minus your trade-in allowance. Private-party sales get no trade-in deduction because there's no second vehicle changing hands at the dealer to offset.
Is the sales tax rate the same everywhere in Colorado?
Not close. The state rate is 2.9% everywhere, but cities, counties, RTD (Denver-metro transit) and the Scientific & Cultural Facilities District stack on top. Denver lands around 9.15%, Aurora around 8.5%, Colorado Springs around 8.2%, while an unincorporated county address with no city tax can be near 5%.
What happens if I don't register within 60 days?
A late fee of $25 kicks in for every month or partial month you're overdue, capped at $100 total - there's no grace period, it starts the day after the deadline. That's separate from the sales tax, SOT, and registration fees, which are still fully owed on top.
Do electric vehicles pay different TTL in Colorado?
Sales tax and SOT are the same regardless of fuel type. Registration is where EVs differ: a battery-electric vehicle adds roughly $76/year (a $50.05 base plug-in fee plus a $26 road usage equalization fee for FY2026-27), and that equalization piece is scheduled to keep rising through FY2031-32.
