Colorado rate / penalty13% for 2026 (discount rate + 9), premium bidding

Park County, Colorado opens its 2026 tax lien sale on Monday, November 2 at 8:00 a.m. MST on Zeus Auction, and the batches start closing on Wednesday, November 4 at 1:00 p.m. MST. The Zeus listing showed 1,706 liens on October 16, more than any other Colorado county on the platform except Jefferson. Registration closes October 28 at 11:59 p.m., no deposit is required, and returning buyers keep their Park County buyer number.

Timetable for the 2026 sale

October 9: the 2026 Delinquent Tax Sale List and its addendum, as published, go up on ZeusAuction.com, and registration opens at 8:00 a.m. The list is updated daily until the morning of November 2, as owners pay.

October 28: two deadlines on the same day. Owners can pay their advertised delinquent taxes until 3:00 p.m. MST, in full (taxes, interest, penalties and advertising fees) and in the Treasurer's office by then; postmarks do not count, and since September 11 only certified funds, cash or an online card payment are accepted. Bidders must be registered by 11:59 p.m.

November 2, 8:00 a.m. MST: bidding opens. November 4 from 1:00 p.m. MST: the auction closes in batches. The Zeus listing runs the sale with an unsold batch, so liens that draw no bid in their own batch get a second chance in a final batch before the sale ends.

Registration and the Park County buyer number

Park County tracks investors by a buyer number, and it explains how to keep yours: existing buyers are matched by one of three identifiers, a Social Security number, an employer identification number or an individual taxpayer identification number (ITIN). As long as one of these matches, your existing buyer number carries over. The mention of the ITIN matters for non-resident investors, who often hold one instead of an SSN.

Registration includes the IRS W-9 and an ACH authorization, so the liens you win can be withdrawn from the account you registered. There are no deposits. The county asks for plain text on the forms, without accents or symbols, since the certificates are printed from them.

Address changes can be made on Zeus while registration is open. After the sale, any change of address goes to the Park County Treasurer's office, and keeping it current is the certificate holder's job; it is where redemption money is sent.

County officials and employees, their immediate families and their agents cannot buy a lien in the sale while they hold office (C.R.S. 39-11-151).

What you are bidding on

Bidding on each lien starts at the total amount published in the newspaper. Anything bid above that is a premium bid, and if the property is redeemed the premium is neither returned nor paid interest. On a list of 1,706 liens, many of them small, a premium can easily exceed the interest a lien will ever earn; set a maximum before the sale opens.

The interest itself is set by state law at nine points over the September 1 federal discount rate, which the Colorado Banking Commissioner fixed at 13% for 2026 (C.R.S. 39-12-103).

The county is direct about what the certificate is not. You do not own the land; you hold a lien against it, and buying a lien gives you no right of possession, use, improvement or access. Do not visit a parcel expecting to treat it as yours.

The Treasurer says it makes a significant effort to spot problem liens and withholds them from the sale, but calls the sale buyer beware all the same. Property details are on the auction site; doing your own research is the way to reduce the risk.

Seven years, and a deed only by public auction

Park County states the new rule plainly: a lien is valid for seven years from its original issue date. After three years from the sale you may apply for a Public Auction of a Certificate of Option for a Treasurer's Deed; if you never apply, the lien is cancelled after seven years (C.R.S. 39-11-148, as amended by Senate Bill 26-144).

That changes the math for anyone buying in Park County hoping to end up with land. The lienholder no longer receives the deed directly: the option is auctioned, and the outcome depends on who bids. Treat a 2026 Park County lien as a 13% interest instrument with a seven-year clock, not as a path to a mountain lot.

The Treasurer says more information will be posted as the auction date approaches. Check the Zeus listing for updated rules before November 2.

Three ways people lose money here

  1. 1. Waiting until the last day to register

    Registration closes October 28 at 11:59 p.m., five days before bidding opens.

  2. 2. Bidding from an old list

    The list is updated daily until the morning of November 2. Liens paid after you downloaded it are gone.

  3. 3. Treating the lien as ownership

    A lien gives no right of possession, use or access. Deeds now go through a public auction.

County snapshot

Population (2024)18,316
Change since 2020+5.1%
Net migration (2024)+199

Park County has grown 5.1% since 2020 and still shows positive net migration (199 people in 2024). Demand for housing usually means owners redeem rather than walk away — good for the interest, less good if you were hoping to take the deed.

By population, Park County is the 27th largest of Colorado's 64 counties. It has grown faster than the state average (+1.9% across Colorado), so competition at the auction is likely to be heavier here than in the quieter counties. Of the 2024 change, 199 came from people moving in and 7 from deaths outnumbering births.

Property & tax profile

Median home value$532,100
Median tax / year$1,771
Tax / home value0.3%
Owned outright32.9%
“Other vacant”0.8%
Median year built1992

The median homeowner in Park County pays $1,771 a year in property tax — below the Colorado median of $2,602 (U.S.: $3,119). That is roughly what a typical home here owes after one missed year — about the face value of a one-year certificate, before interest, fees and any premium. Homes with a mortgage pay a median of $1,839; homes owned outright, $1,660.

On a home with a mortgage, the lender has its own reason to pay a delinquent tax bill: the tax lien outranks the mortgage, and a tax deed can wipe out the loan. On a home owned outright, nobody but the owner — or the heirs — has that reason. In Park County, 32.9% of owner-occupied homes are owned outright (Colorado: 30.6%, U.S.: 39.4%). About the same as the state as a whole.

36.1% of all housing units in Park County are vacant. 32.9% of all units are seasonal or vacation homes, empty by design rather than abandoned. The figure that matters for a lien buyer is the Census “other vacant” category — not for rent, not for sale, not a holiday home, but a catch-all that includes foreclosures, homes held up by legal proceedings or family reasons, homes needing repairs, and abandoned ones. Here it is 0.8% of all units (Colorado: 1.7%, U.S.: 3.6%). That is below the state rate: fewer empty properties on the list than elsewhere in Colorado.

Half of the homes in Park County were built in or before 1992 (Colorado: in or before 1988). The typical tax bill is 1.7% of the median household income of $103,670 (Colorado: 2.7%).
