Colorado Tax Sale Questions
When are Colorado tax lien sales held?▾
Annually, once per year, typically in October or November. Registration usually opens in late September.
How is the Colorado tax lien interest rate set?▾
It is set annually at 9 percentage points above the federal reserve discount rate in effect on September 1, rounded to the nearest full percent. The 2025 sale rate was 14%.
Does the premium I bid earn interest in Colorado?▾
No. The premium you pay above the taxes-and-costs base earns no interest and is never refunded on redemption — only the base accrues interest, so large premiums cut your effective yield.
How long until I can apply for a treasurer's deed in Colorado?▾
3 years from the date of the tax lien sale. Redemption is allowed any time before the deed is actually executed, so the practical window can run longer, and the certificate stays valid up to 15 years.
