  • Employees and officials of Mesa County, members of their immediate families or their agents may not acquire a tax lien at the Mesa County Tax Lien Sale per C.R.S. 39-11-151.

  • “Premium bidding” is at the discretion of the bidder up to 30%. If you bid above 30% in premium you will receive a warning message but can pass by the warning if you choose. Premiums on winning bids are a cost of securing the tax lien and are not returned nor do they draw interest.

  • Each batch containing approximately 200 properties will close in one-hour increments. For example, on sale day, Batch 1 will close at 9:00 a.m. (M.D.T.) Batch 2 will close at 10:00 a.m.; Batch 3 will close at 11:00 a.m.; Batch 4 will close at 12:00 Noon; Batch 5 will close at 1:00 p.m.; and Batch 6 will close at 2:00 p.m. If properties remain the final auxiliary batch will close at 5:00 p.m.

  • Once a batch closes, the bids become final and may not be changed or withdrawn.

  • All successful auction results will be posted by bidder number..
  • If a mobile home is located on leased land, the tax lien holder is eligible to apply for a Certificate of Ownership one year after the date of sale.

  • If a mobile home is located on land owned by the same owner as the mobile home, the tax lien holder is eligible to apply for a Certificate of Ownership three (3) years after the date of sale.

The interest rate will be 12% this year as determined by the Colorado Banking Commission. This rate is updated each September.

  • Premiums do not draw interest.

  • When redeemed, your certificate will pay nine points over the Federal Discount Rate.  Certificates will earn 9% for the current year’s sale.

  • The interest rate may vary annually. The rate is established each year by adding nine percentage points to the federal discount rate and rounding to the nearest percent.

The minimum starting bid for each tax certificate is equal to the amount of the unpaid taxes, interest, penalties, and fees.

Each winning bidder shall make a payment of funds sufficient to cover the total amount of the bidder's winning bids on the Auction Website or in person using certified funds or cash no later than November 1, 2022, 2:00 p.m. MDT;

  • If a winning bidder fails to make such payment by this time, the Treasurer may, in the Treasurer’s sole discretion, award the tax certificates to another bidder or may offer the tax lien for sale in accordance with C.R.S. 39-11-116.
  • If a winning bidder fails to pay the amount due from bidding on sales, the Treasurer may prohibit a person from participating in future sales up to five years [C.R.S. 39-11-116].
  • Each bidder must be registered on Mesa County's Auction website before they are allowed to participate in the Tax Lien Sale.

  • Each bidder must make a deposit equal to ten percent (10%) of the total dollar amount of tax certificates the bidder anticipates winning. Final determination regarding the acceptability of any deposit is at the distinction of the Mesa County Treasurer.

  • If the owner does not pay future taxes before August 1st each year, you will be notified of the amount due and you may pay them if you wish. Your payment will be endorsed onto your lien and will accrue interest at the same rate as your certificate.

Customer Service Questions



You do not have ownership right to the property, simply a property tax lien.

  • It is the Bidder’s responsibility to know the quality of the property on which they are paying the taxes and receiving a lien.

  • At the close of the auction, all successful bids are final. No changes in, or cancellation of, liens can be made after the lien is sold.
  • The majority of properties are redeemed.  You do not have ownership rights to the property, simply a property tax lien; this is an investment.

  • A Treasurer’s Deed may be applied for three (3) years after the date of the sale if the property remains unredeemed.  A deposit shall be required to cover expenses.
