Colorado imposes a flat 4.4% income tax rate on all income, including capital gains. This flat rate simplifies tax planning for home sellers since there is no bracket creep to worry about. The rate is moderate compared to neighboring states, making Colorado reasonably competitive for real estate investors.
Colorado does not offer a separate capital gains rate or deduction for investment property sales. All gains are taxed uniformly at 4.4%. However, the state does allow certain deductions that can reduce your overall taxable income, including a partial deduction for retirement income that may benefit older sellers.
The Denver metro area and Front Range corridor have seen significant appreciation over the past decade, with many homeowners sitting on gains that exceed the federal exclusion. At Colorado's 4.4% rate, a $200,000 taxable gain results in $8,800 in state tax on top of federal obligations.
Mountain resort areas like Aspen, Vail, and Breckenridge often involve second homes that do not qualify for the primary residence exclusion. Sellers of ski properties and vacation homes should plan for the full combined federal and state tax bite, which can exceed 25% on long-term gains.
