Jefferson County auction guide
Jefferson County's November 12 and 13, 2026 online auction sells tax lien certificates. The county lists a 13 percent certificate interest rate for this sale. Premium bids earn no interest and are not refunded.
What you buy
A certificate is a lien investment, not ownership of the property. The buyer pays delinquent taxes, interest and costs, plus any bid premium. The certificate records the legal description, purchase amount, sale date and lawful interest rate for its life.
Registration
Register through the county's Zeus Auction link. The W-9 submitted at registration determines the certificate name, so enter it exactly as you want it to appear.
Premiums and interest
Certificate interest applies to the face amount. A premium earns no interest and is not repaid. Keep it separate when calculating the cash you would commit, and read the current notice for the certificate's terms and later steps.
Research and eligibility
The county makes bidders responsible for their own research. It says it has never deeded a house or building of substantial value for unpaid taxes. Its page also cites the prohibition on county officials and employees acquiring land through tax sale.
