Taxes in Colorado: Features and Advantages

Main Taxes in the State of Colorado

Income Tax:

Colorado applies a flat income tax rate of 4.4% (as of 2025) for all taxpayers. The tax is levied on wages, business income, rental income, capital gains, interest, and dividends. The state also recognizes most federal deductions and offers its own tax credits for families with children, retirees, and charitable donations.

Sales Tax:

The base state sales tax rate is 2.9%, but Colorado is one of the most decentralized states for this tax. Cities and counties can set their own rates, often quite high, bringing the total rate to 8.5–11% in some municipalities. In addition, there is a distinction between state-collected and home-rule jurisdictions, where tax administration differs, significantly complicating calculations and reporting.

Property Tax:

Colorado has relatively low property tax – the average effective rate is about 0.55% of market value, below the national average. However, rates vary depending on the county, school district, and special districts.

Business Taxes:

C‑corporations are taxed at a rate of 4.4% – the same as the personal income tax rate. Colorado does not levy a Franchise Tax, which distinguishes it favorably from states such as Delaware, Texas, or California. An Annual Report is mandatory for all registered entities — LLCs, corporations, and nonprofits. Businesses must also declare tangible personal property if its value exceeds established thresholds.
