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.

Official websiteCounty notes
- Broomfield is a consolidated city and county, so a single municipal government runs both the city and the county treasurer functions. The Treasurer listed on the office page is Waishing Chiem, reachable at treasurer@broomfield.org, phone 303-464-5810, fax 303-464-5105.
- The city website states that in Broomfield the County Treasurer functions are split between the finance director (investments and reconciliation) and the revenue manager, with the treasurer handling billing, collection, and distribution of property taxes.
- As of this research the county's sale page was still titled and dated for the 2025 sale held November 12, 2025, and no later sale date had been posted. Treat November as the expected window and confirm the exact date with the office.
- City and county employees and their immediate families are barred from purchasing tax liens at the sale.
- The county publishes the full delinquent list as an on page public notice rather than a downloadable spreadsheet, with parcel number, owner, legal description, situs address, and total due for each item.
- Third party tax sale data sites republish Broomfield listings, but none of them conduct this auction. Bids are only accepted in person in Council Chambers on sale day.
Colorado rules
- Redemption
- Redemption may be made at any time before a treasurer's deed is executed, so the practical window runs well past the three-year mark and through the Article 11.5 auction process. The treasurer must hold that public auction between 110 and 125 calendar days after the known interested party notice is first published or mailed, which gives owners and junior lienors a further defined period to pay. A separate rule lets an owner who was under a legal disability when the deed was executed 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 post a deposit covering the recording fee plus the actual and reasonable cost of administering the auction, and all Article 11.5 fees and costs are chargeable as additional amounts owing under the tax lien. For bidders, the treasurer accepts cash, cashier's check, bank check, or electronic funds transfer subject to the treasurer's bidding rules. The statute sets no fixed bidder deposit percentage, so the deposit terms come from county bidding rules.
- Surplus proceeds
- Any overbid goes first to junior lienors in order of recording priority, measured as of the recording date of the application for public auction, who filed a notice of intent to redeem and whose liens are unredeemed, up to each lien's unpaid amount plus fees and costs. Whatever remains is paid to the property owner. The treasurer must post a public notice about these funds and mail the owner a notice within thirty calendar days of the auction. Unclaimed remaining overbids sit in escrow for six months without interest, then transfer to the state administrator under the Revised Uniform Unclaimed Property Act. An agreement to pay someone to recover an owner's overbid is unenforceable, and inducing one is a class 2 misdemeanor.
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.
