Bidding Rules for Annual Public Auction of Delinquent Real Estate Taxes

2021 Tax Lien Sale (For Tax Year 2020 and priors)





  • If you taking part in the sale you cannot be a County employee, their spouse or family member nor can you be an agent for them per C.R.S. 39-11-151.
  • The tax lien parcel list is created to the best of our knowledge. If the parcel is later discovered as a “wrongfully sold tax lien” the Tax Lien Certificates of Purchase sold would only earn 8% per annum.
  • Those investing in tax liens do so at their own risk and are advised to exercise due diligence in carefully analyzing which tax liens to bid on. There are no guarantees expressed or implied regarding whether a tax lien will prove to be a profitable investment.
  • The property information accessible on the bid pages was obtained from the Assessor’s office and is for reference only ( please note that this property information, provided by the assessor’s office, represents the most current assessment year, not the tax year associated with this tax lien sale, as taxes are paid one year in arrears).  It is the buyer’s responsibility to research auction items thoroughly prior to placing bids.
  • Sequence of Sale will be done as followed:
  1. Delinquent taxes will be done with premium bidding; bid increments shall be one dollar ($1.00). Premium bids are not refundable and do not earn interest.
  2. Minimum bids are equal to the amount of the unpaid taxes, interest, penalties, and fees.
  3. Preliminary bidding for tax liens begin on Friday, October 8th, 2021. The tax sale auction will conclude on Thursday, November 4th, 2021 at 12:00 PM MST and all bids must be submitted by that time.  Once the batch closes, the bids become final and may not be changed or withdrawn.
  • All investors are required to submit a deposit via ACH equal to or more than 10% of their total anticipated winning bids by Thursday, October 28th, 2021 at 2:00 PM MST.
  • All payments must be made via ACH by Friday, November 5th, 2021, 2:00 PM MST. If you are unable to render the funds within the timeframe, your properties will be available for sale to the first interested party. This would be considered forfeiting your bid which will result in a five year period where neither you nor an agent for you may take part in our County tax lien sale.
  • All bidders are required to complete the online registration which includes name that will go on the certificates, address and Social Security number or Tax Id. Bidders are responsible to assure that their information is correct as IRS W-9 forms, tax lien certificates, refunds and redemptions are prepared from this information.
