4 Ways to Renew Your Vehicle Registration

Renewal postcards are mailed out right before the month of expiration. In Colorado, you can renew up to the last day of the month after expiration (known as the one-month grace period) without accruing late fees. However, we recommend that you do not travel out of state on expired tags as other states may not honor the grace month.

Starting in January 2023, ​​​you will have the option to get a $29 Keep Colorado Wild (CO State Parks) Pass when you renew your vehicle registration. The $29 fee will automatically be included in the price of your registration renewal unless you opt out.
