Notes
Colorado tax-lien county. Jefferson County Treasurer sells tax lien certificates annually (typically November) online via SRI / Zeus Auction — not RealAuction. Lien holder may endorse subsequent unpaid taxes. Property owner has three years to redeem before certificate holder may apply for public auction of a certificate of option for Treasurer's Deed (post-HB24-1056 reforms affect deed issuance statewide). County sells the lien, not the property, at the tax sale.

Colorado assesses residential property at two rates since SB24-233. For school district purposes the 2026 residential rate is 7.05% of actual value; for local government purposes 6.95% is applied to actual value less the lesser of 10% of actual value or $70,000 as adjusted for inflation, an effective rate near 6.26% below $700,000. Commercial and agricultural property is 25% for 2026, down from 27% in 2025. This entry uses the school rate, the higher of the two residential figures.
