Colorado Title Transfer in a Private Sale: 60-Day Rule, Emissions and Tax

For a Colorado private-party sale, the seller signs the title, takes the plates and reports the sale on myDMV within 5 days, and the buyer has 60 days from the purchase date to title and register at their county motor vehicle office. The state title fee is $7.20, but the real bill is sales tax (2.9 percent state plus local rates the county collects from you) and the first year of registration. Go past 60 days and late fees run $25 per month, up to $100.

I read the Colorado DMV's private sale, title, registration and taxes-and-fees pages on October 16, 2026. The DMV site blocks a lot of automated traffic, so those pages are cited by name below instead of linked, and anything county-specific comes from Adams County's own fee page. Colorado is friendlier than some states on timing, and stricter on two things people forget: emissions paperwork and the VIN inspection for cars titled out of state.

What the seller owes the buyer

The DMV's "Private Sale: Buying or Selling a Vehicle in Colorado" page has the seller sign and print their name in the seller section, exactly as it appears on the front of the title, and fill in the odometer. Federal rules in 49 CFR 580.17 require that disclosure for model year 2011 and newer cars until they are 20 years old. A bill of sale (the secure DR 2173 or a written equivalent) is listed as best practice, and it becomes required if the price isn't written on the title.

Then the seller pulls the plates. Colorado plates belong to the owner, and the DMV warns a seller who leaves them on can end up with the buyer's tolls and fines. Within 5 days the seller can file a release of liability on myDMV or at the county office. If the car has any brand on it, both sides complete the DR 2710 Branded Title Disclosure, and a car labeled junk or parts-only can't get a Colorado title at all.

Emissions: who has to test, and who pays

This one catches out-of-county buyers. If the car is more than 7 model years old and the buyer lives in an emissions-testing county, the DMV puts it on the seller to hand over a new passing certificate. The registration page names Denver, Boulder, Jefferson and Douglas as examples. Air Care Colorado lists $35 for a 1982-or-newer test, with stations open 8 a.m. to 5:30 p.m. weekdays and 8 a.m. to 1 p.m. Saturdays.

So look, if you live in Lakewood and the seller is in Pueblo, settle who is getting the test before you agree on a price. The DMV also tells buyers to check that the passing test matches the VIN and to watch for mismatched fonts or edited numbers on the form. Fake emissions certificates exist. They are not a myth from a forum thread.

The buyer's 60 days and the 36-hour drive home

Buyers get 60 days from the date of purchase. The taxes-and-fees page is blunt that temporary tags have no grace period, so an expired temp tag starts the $25-a-month late fee. Get Colorado insurance before you drive, at least the $25,000/$50,000/$15,000 minimum the registration page lists.

Driving home without plates is allowed for up to 36 hours from the seller's place to your home or a registration office, carrying a bill of sale signed by both of you that shows year, make, VIN and the date and time of sale, plus proof of insurance. A later section of the same page ties that 36-hour window to sales on a Saturday, Sunday, holiday or when your county office is closed. Honestly, the page is a little inconsistent, so treat it as a straight-home-only allowance and get a temporary permit if there is any doubt.

Out-of-state titles need a VIN inspection

If the title came from another state, Colorado wants a DR 2698 VIN verification before titling. The registration page says Colorado law enforcement, a licensed Colorado dealer or an emissions station can do it, and Air Care lists the VIN verification at $25. Our VIN verification for title transfer post covers where the numbers are stamped, and out-of-state title transfer and CARFAX explains why a fresh-from-another-state title deserves a closer look.

Sales tax, ownership tax and the county total

A private seller doesn't collect sales tax, so your county does. Adams County's fee page lists the $7.20 title fee, the 2.9 percent state rate, 1.1 percent RTD, a 0.75 percent county tax that applies only if you bought from another Adams County resident or dealer, and city rates such as Aurora at 3.75 percent. An Aurora buyer paying $12,000 to another Adams County resident would owe roughly 8.5 percent, about $1,020. Registration then adds Specific Ownership Tax, which the DMV says is based on the car's original MSRP and age and drops as the car gets older, plus a $4 clerk hire fee and other surcharges. Use the myDMV fee estimator for your exact number.

Check the car's past before the paperwork

The DMV itself tells buyers to confirm the VIN matches, check the state's stolen-vehicle system and search NMVTIS. AAMVA's short "Check NMVTIS Before You Buy" video, which the DMV links, explains why. In Colorado, hail is the classic hidden story; read Colorado hail salvage titles and Colorado salvage and rebuilt title rules before buying a car with a too-good price. CarVins sells official CARFAX and AutoCheck reports as a licensed reseller, unaffiliated with CARFAX, AutoCheck or Experian. Recent prices: about $5.50 guest, $4.50 member, about $6.75 for the pair, versus roughly $39.99 to $44.99 retail. Check the live total at checkout, and pull your own instead of trusting a seller's PDF. CARFAX's overview lists what a report covers.
