Colorado Tax Information
Colorado has a flat 4.4% income tax. Corporate tax: 4.4%. Home-rule cities (Denver, Boulder, etc.) collect their own sales taxes independently from the state, creating significant complexity.
Sales Tax: 2.9% state rate, local rates vary dramatically (combined rates: 2.9% in unincorporated areas to 11.2% in some home-rule cities)
Starting a Business in Colorado
Register with CO Secretary of State. LLC filing: $50. Annual report: $10. Businesses must register with both the CO Department of Revenue AND individual home-rule cities for sales tax.
Colorado has one of the most dynamic economies in the Mountain West, driven by technology and aerospace in the Denver-Boulder corridor, energy (both traditional and renewable), outdoor recreation and tourism, a booming cannabis industry, agriculture, and military installations including NORAD, the Air Force Academy, and multiple Space Force operations.
Colorado's flat 4.4% income and corporate tax rates are competitive, but the state's sales tax system is notoriously complex. Colorado has more than 700 sales tax jurisdictions, and home-rule cities like Denver, Boulder, Aurora, and others collect their own sales taxes separately from the state—each with different rates, rules, and filing schedules. This makes Colorado arguably the most complex state for sales tax compliance.
Colorado offers incentive programs including enterprise zone tax credits, the Advanced Industry Investment Tax Credit, and Job Growth Incentive Tax Credits. The cannabis industry faces unique federal-state tax conflicts under IRC Section 280E that require specialized bookkeeping.
