What this rate applies to

Colorado publishes the taxable base separately from the rate. Groceries, prescription drugs, clothing and services are treated differently state to state, and several categories in Colorado are taxed at reduced rates or exempt entirely. Aurora spans three counties — Arapahoe, Adams and Douglas — so the county component depends on which side of the city line an address sits. Check the Colorado Department of Revenue guidance for the category you are pricing before assuming 8% applies.
