No. You won't owe Colorado tax either. While Colorado does have a capital gain tax on the sale of a residence, they have the same exclusion as federal tax. If you lived in your house for two of the past five years you can excluded up to $250,000 ($500,000 if married filing joint) in gain on the sale of your house.
