After you establish residency in Colorado, the Motor Vehicle Division says you must title and register your vehicle within 90 days. You are a resident if you own or operate a business in Colorado, you are employed in Colorado, or you reside here for 90 consecutive days. The driver's license has a shorter clock, 30 days, but that is a license rule, not the vehicle rule. County motor vehicle offices, not a single state counter, handle the title and registration.
Proof of insurance is required at the visit. The welcome page states the minimum liability coverage as $25,000 for bodily injury to one person, $50,000 for all persons in an accident, and $15,000 for property damage. You also need a VIN verification before the office visit unless the vehicle is new and titled on a manufacturer's statement of origin.
What has to happen, in order
- Establish which residency test you meet. The 90-day vehicle clock runs after residency is established.
- Get a Colorado auto policy at the minimums above, or a policy the county will accept as proof of active Colorado insurance. The welcome page calls it proof of active Colorado auto insurance.
- Complete VIN verification on form DR 2698, unless the car is new on a manufacturer's statement of origin. Law enforcement, a licensed Colorado dealer, or a Colorado emissions station can do the inspection.
- If the vehicle is more than seven model years old and you live in a designated emissions county, get the emissions test. The welcome page gives Denver, Boulder, Jefferson, and Douglas as examples.
- Take the packet to the county motor vehicle office where you reside. Complete the Application for Title and Registration, form DR 2395. Pay title fees, registration fees, and any state or local tax the office calculates.
- Surrender the old plates at the county or to the former state. Standard green-and-white plates are handed to you that day. Other plates are printed and mailed.
Documents
Bring the out-of-state title. If a bank holds it, bring the most recent out-of-state registration, which must be current or expired less than six months, and the lienholder's name and address. Bring a secure and verifiable ID. The welcome page says that generally includes a current or recently expired Colorado or out-of-state driver license or ID, a U.S. passport, a U.S. military ID, and certain immigration, tribal, or citizenship documents. The full list is on form DR 2841. Complete form DR 2504, Colorado Residency Establishment, and bring a proof-of-residency document such as a utility bill, lease, or mortgage statement.
Inspections
VIN verification is a physical inspection of the identification number. It is required for an out-of-state vehicle unless the exception for a new vehicle on a manufacturer's statement of origin applies. Emissions testing is not statewide. It applies when the vehicle is more than seven model years old and is registered in a designated emissions county. The gas-emissions page, opened the same day, is labeled "2026 Gas Emissions Requirements." Its bullet list says 1982 and newer vehicles more than seven model years old are tested every two years and the fee is $35, and that 1981 and older vehicles without collector plates need a yearly two-speed idle test at a $20 fee. The table on the same page uses different year bands and, for some older vehicles, a $35 fee. Use the table for the model year in front of you, and call the State Emissions Program at the number on that page if the table and the bullets disagree.
Tax
The Department of Revenue's motor-vehicle sales publication draws a line between a purchase and a move. A motor vehicle sale outside Colorado is not subject to Colorado sales tax, because the sale occurs where the buyer takes possession. If someone then registers that purchased vehicle in Colorado, use tax and any local use tax are due at registration. Credit is allowed for sales, use, or similar tax the state of sale legally imposed. Credit is not allowed for tax paid to a foreign country or its subdivision, or for tax a state did not legally impose.
If a nonresident moves into Colorado and acquires residency, no use tax applies to a motor vehicle acquired outside Colorado and brought into the state when acquiring residency. Leased vehicles are excluded from that sentence. The publication points lease questions to a separate motor-vehicle lease publication. County clerks also collect specific ownership tax, which the DMV taxes-and-fees page describes as a property tax paid when you register. That is not the same as the use tax above. The taxes-and-fees page does not print one statewide registration fee. It says the annual total combines specific ownership tax, registration fees, and other surcharges.
Temporary permits, students, and military
A Colorado dealer issues a 60-day temporary permit. An out-of-state purchase still has to be registered within 60 days, even if that other tag lasts longer. Specialty plates generally take 21 days by mail, and the county can issue a temporary permit for the wait.
Students whose primary purpose in Colorado is education do not need to register vehicles here. The page says Colorado recognizes their out-of-state plates. Active-duty military and spouses with a valid out-of-state license are exempt from a Colorado driver license. Dependents are not. Active-duty members stationed here who claim another state as home can still register vehicles at the county office, and they may claim a specific-ownership-tax exemption on form DR 2667 each year at renewal.
A shipped car
The 90-day period starts when residency is established, not when you drive across the line. A car that arrives on a truck still needs the VIN verification, and the emissions test if the county and model year require it, before the county will finish the registration.
