These are the Colorado statutes that decide how tax lien certificates and tax deeds are sold. Each links to the official text so you can read the exact language before you rely on it.

The governing law

Colorado is a tax-lien state. Each year the county treasurer holds a public auction of tax liens on parcels whose prior-year taxes are still delinquent, and the auction must commence on or before the second Monday in December. Bidding is premium bid: the lien opens at the taxes, delinquent interest, and fees then due, and it goes to whoever pays the largest amount in excess of that figure. The premium is credited to the county general fund, so it is not part of the investor's return. The certificate earns redemption interest at a single statewide rate that the state bank commissioner resets every September 1, which is 13 percent for the rate year that began October 1, 2026. After August 1 of the third calendar year following the sale, the certificate holder may apply for a treasurer's deed, and the treasurer then sells the property at a public auction under Article 11.5. That article replaced direct deed issuance on July 1, 2024, and SB 26-144 repealed and reenacted it effective June 1, 2026.
