When it runs
Registration and deposit
What sells is a certificate of option for treasurer's deed, not the parcel outright. The treasurer may only accept bids above the combined amount owed to the lawful holder plus the treasurer's fees and costs. County officials, county employees acting in their individual capacity, and their immediate family members may not bid. Payment is by cash, cashier's check, bank check, or electronic funds transfer subject to the treasurer's bidding rules. Any overbid goes to junior lienors who filed a notice of intent to redeem and then to the property owner. Confirm the notice, the bidding rules, and the auction venue with the county treasurer.

Check the state rules that change the bid
Read the Colorado due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in Colorado before you price the title work.Set a walk-away number
Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.
Over-the-counter (leftover) purchases
unsold liens and deeds
Liens that draw no bid are struck off to the county and the treasurer issues the county a certificate of purchase. The county may then assign, sell, or transfer those certificates in the manner, at the times, and on the terms set by resolution of the board of county commissioners, which is how county-held liens are sold between annual auctions. A certificate on property owing more than ten thousand dollars in taxes needs the property tax administrator's approval after published notice. Whether a county maintains a published county-held list, and on what terms, varies. Contact the county treasurer.

County notes
- The Treasurer also serves as Public Trustee; the same office handles both tax lien sales and deed-of-trust foreclosures.
- Office hours are Monday through Friday, 8:00 a.m. to 4:00 p.m.; the elected Treasurer is Lori Ehmke and the Deputy is Leanne Sloan.
- Email contacts published by the county: sctreas@sedgwickcountygov.net for the Treasurer and publictrustee@sedgwickcountygov.net for the Public Trustee.
- The county's general Tax Lien Sale page repeats the statewide rate rule (nine percent above the federal discount rate, set September 1) and notes the purchase amount covers tax, delinquent interest through December, advertising, and certificate fees.
- The Treasurer's menu also carries pages for endorsement of tax liens, redemption of tax liens, and the Treasurer's deed process, which matter for holders after the sale.
Colorado rules
- Redemption
- Redemption may be made at any time before a treasurer's deed is executed, so the practical window runs past the three-year mark and into the Article 11.5 process. Once a deed application is pending, the owner must file an intent to redeem with the treasurer no later than seven calendar days before the scheduled public auction, then pay the amount on the redemption statement while it is in effect, and must redeem the entire property. The auction itself is set 30 to 60 calendar days after the treasurer mails the notice of public auction. A separate rule lets an owner who was under a legal disability when a tax deed was executed under Article 11 redeem within nine years of the deed being recorded, at 15 percent per year plus the present value of any improvements.
- Deed deposit
- The treasurer may require the applying lawful holder to deposit up to one thousand dollars plus statutory fees when the application is accepted, applied against the treasurer's fees and costs, and all Article 11.5 fees and costs are chargeable as additional amounts owing under the certificate of purchase. A third-party winner may be charged up to three hundred dollars for processing. The statute sets no bidder deposit percentage, so payment terms come from the treasurer's written auction policies.
- Surplus proceeds
- Junior lienors whose liens were recorded before the application for treasurer's deed may file a claim for overbid money within eight business days after the auction. Between the ninth and fifteenth business day the overbid is paid to them in order of recording priority, each up to the unpaid lien plus fees and costs, and whatever remains goes to the property owner. The treasurer mails the owner a notice within thirty days after the claim period ends. Unclaimed overbid stays in escrow for two years without interest to the claimant. Amounts under twenty-five dollars left unclaimed for six months go to the county general fund, and larger amounts left unclaimed for two years go to the state treasurer as unclaimed property. An agreement to pay someone to recover an unclaimed overbid is enforceable only if the fee is capped at ten percent and the agreement is made at least two years after the transfer.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
