How the tax works
Colorado charges vehicle sales tax at your home address, so a Denver-metro address adds RTD (1%) and cultural-district taxes that a rural one won't — the ~7.01% shown is typical around Greeley. The Specific Ownership Tax is where most of your annual cost goes on a newer car; it's based on 85% of MSRP and drops each year. Estimate it on our Colorado registration page.
