This calculator estimates Colorado sales tax on a purchase and the total you’ll pay (or, if tax is included, the tax portion). It’s for shoppers and small sellers who need a quick, location-aware number. You’ll need the price, whether tax is included, and either your combined local rate or a preset city rate. Colorado’s state sales tax rate is 2.9%, but the total you pay usually depends on local taxes (county, special districts, and sometimes home-rule city taxes). Colorado DOR notes that local taxes can be state-administered or home-rule (self-collected), so rates can vary by address. This calculator supports tax-included pricing, optional shipping, discounts (store vs manufacturer coupons), and the Retail Delivery Fee (RDF). For July 2025 through June 2026, the RDF totals $0.28 per delivery. The fee is not subject to state or state-administered local sales taxes, but may be taxed by home-rule cities. Checked January 28, 2026 (Europe/Madrid). Informational estimate only—confirm rates with Colorado’s lookup/GIS tools or your local jurisdiction.

FAQs

What is the Colorado state sales tax rate?

Why is Denver’s total rate higher than the state rate?

Because Denver adds local taxes on top of the state rate; Denver’s combined rate is 9.15% per published city information.

Do home-rule cities work differently?

Are shipping/delivery charges taxable in Colorado?

Often yes—Colorado generally includes delivery/installation charges in the taxable purchase price unless the charge is separable and separately stated.

Do coupons change the taxable amount?

They can. Colorado distinguishes manufacturer coupons vs store coupons; manufacturer coupons generally do not reduce the taxable selling price the same way a store discount does.

What is the Colorado Retail Delivery Fee and how much is it?

Is the Retail Delivery Fee subject to sales tax?

It is not subject to state and state-administered local sales taxes, but may be taxed by self-collecting home-rule jurisdictions.

Are groceries exempt from sales tax in Colorado?

Colorado provides guidance for food for home consumption vs prepared food; local treatment can vary by jurisdiction.

Are prescription drugs taxed?

Why doesn’t my result match my receipt exactly?

Common reasons include local jurisdiction differences, home-rule rules, taxable vs non-taxable shipping structure, and rounding method.
