Delinquent Property Tax List

The 2015 Delinquent Tax Sale List (as published) will be available on October 7, 2016 at RealAuction, and Park County Tax Sale. The list will be updated daily at RealAution and Park County Tax Sale until the morning of November 4, 2016, the day of the sale.


  • All potential bidders must register before November 4, 2016.

  • Existing Park County tax lien buyers are identified by one of three ways:
    • SSN - Social Security Number
    • EIN - Employer Identification Number
    • ITIN - Individual Taxpayer Identification Number
         As long as you find one of these identifiers you will be able to retain your existing Park County Buyer
  • The registration will include the completion of an IRS required W-9 form as well as ACH depository requirements. Further details of the registration process are available on the Website.
  • At the time of registration you will be asked to complete an ACH authorization so that you can make payments for the tax liens purchased.
  • We encourage you to register as soon as the delinquent property tax list is available as you can then research the properties and make a determination of a bid.

Element of Risk

  • Although The Treasurer’s Office makes significant effort to be aware of potential problem liens and therefore withholds them from sale, ultimately the sale is a "BUYER BEWARE SALE" as there is an element of risk inherent in the purchase of tax liens.
  • Please conduct your own investigation in order to reduce the risk.
  • Details of the property are accessible through the auction Website.

Certificate Holder Address Changes

It is the responsibility of the certificate holder to change their address.  These changes can be made online at RealAuction.
