Buying a Car in Colorado: Tax, Fees and Insurance
Sales tax. State rate of 2.9%; city, county and special district taxes are added. The calculator uses the state rate of 2.90%; enter your combined local rate for an exact figure. Dealers add the tax to the amount financed unless you pay it at signing, so it costs interest for the life of the loan.
Trade in. In Colorado the trade in value is subtracted before tax is figured, so a $10,000 trade in saves $290 in tax on top of lowering the loan.
Fees. Title, registration and plate fees are set by the Colorado motor vehicle agency and vary by vehicle; dealer documentation fees are set by the dealer and run from about $100 to more than $800 depending on the state. The calculator uses $300 as a placeholder; replace it with the figures on your buyer's order.
Insurance. The average Colorado car insurance premium is about $1,446 a year, or $121 a month, according to the NAIC, compared with about $1,258 nationally. Lenders require full coverage on a financed car, so budget for it alongside the payment. Compare carriers on the Colorado car insurance page.
