What's different about buying in Colorado

Colorado's 2.9% state rate looks friendly, but Denver-metro combined rates approach 9% once RTD and city taxes stack, and Front Range dealers charge some of the highest doc fees in the country. Colorado also lets you register with a temporary permit while paying ownership tax annually — a system that surprises out-of-state buyers.

Trade-in mathYour trade-in's value is deducted from the purchase price before tax is calculated. A $15,000 trade saves you $435 in tax here — which usually makes trading in beat a private sale once you factor in the hassle.
