Bidding Rules - Weld County, Colorado 2018 Tax Certificate Sale Auction

In accordance with §39-11-115 (2) (c) and (d), C.R.S., minimum bids and bid increase increments are as follows:

Minimum bids: The minimum starting bid for each tax lien is equal to the amount of the unpaid taxes, interest, penalties, and fees (the tax lien face value).

Bid increments: Bid increments shall be one dollar ($1.00). Tax liens are awarded to the highest bidder, or in the event of a tie, the winner will be selected at random by the Auction Website, and the winning bid amount will equal the amount of the tie bid.

Tax liens will be grouped into batches and sold in 1 hour increments starting on 10/31/2018 at 9:00 AM MT and concluding on 10/31/2018 12:00 PM MT. Tax liens in each batch will be identified with a closing time.

Bids may be made starting 10/10/2018 at 8:00 AM MT. Bids will be accepted for each tax lien until the batch containing it closes. The Auction Website stores the bids for each tax lien until the batch containing it closes. Prior to the closing of the batch, bidders may change or withdraw their bids. Once a batch closes, the bids become final and may not be changed or withdrawn.

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 no later than 11/01/2018 at 3:00 PM MT. If a winning bidder fails to make such a deposit by this time, the Treasurer may, in the Treasurer’s sole discretion, award the tax liens to another bidder or may offer the tax lien for sale. The Treasurer may prohibit a person, who fails to pay the amount due from bidding, from participating in any tax lien sales for up to five years in accordance with § 39-11-116, C.R.S.

The certificate of purchase issued on a successful bid will show the legal description, purchase amount, and buyer’s name (as entered in registration), interest rate, and date of sale. Certificate of purchase will be held in our office electronically. This will enable us to process your redemptions and to endorse subsequent tax years.

Redemption interest is 12% per annum.

Employees and officials of Weld County, and members of their families are not allowed to purchase at the Public Auction.



  • 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 prior to the start of the current auction 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.
