Jefferson County Property Tax Notices Have Been Mailed

As of February 14, 2024 the property tax notices for Jefferson County have been mailed. Please allow 7 to 10 business days for delivery. Reminder, Monday, February 19 is a holiday. 

Property taxes can be viewed or paid via our Property Tax and Payment Portal or visit Jeffco Treasurer Property Tax Payment Options for additional ways to pay your taxes. 

In 2024, Jefferson County property taxpayers should expect to see their property tax bills a bit later than in most years. 

The Colorado Legislature has passed a bill to provide property tax relief that will impact the timing of property tax bills being mailed. A two-week delay in certification, the deadline being January 24, 2024, of county tax rolls will cause property tax bills to be mailed later than in most years. The delay is to give taxing authorities sufficient time to certify their mill levies and to give county assessors more time to gather data. 

Please note that these changes do not alter the first-half payment due date for property taxes. The due date will remain February 29, 2024, which is a Leap Year. The decision made by the Colorado Legislature to not alter the payment deadline was to ensure that special districts like fire departments, schools, health departments, and hospitals, as well as other public entities have the revenue to continue to operate. 

Note from Jefferson County Treasurer

Every tax year I receive a few calls from taxpayers asking me to lower or waive their property taxes for various reasons.  The County Treasurer does not have the legal authority to lower or waive property taxes per state law.  

If you need assistance with paying your taxes, there are programs available offered by the state of Colorado. 

If you believe your property has been incorrectly valued or classified, you may file an appeal with the Jefferson County Assessor.

Delinquent Property Taxes are Sold at the Tax Lien Sale

Every November the Treasurer’s office has an online auction for unpaid property taxes. We do not sell the property.  The taxes are purchased by investors. The investor that holds the lien will be notified every August of any unpaid taxes and can endorse those taxes to the existing lien. Owners have three years from said tax sale to payoff the lien before it becomes eligible for a Treasurer’s Deed.

Please contact our office to request the amount due. We will only accept cash or certified funds (e.g. Cashier’s Check or money order) payable to Jefferson County Treasurer for payment of a tax lien. Payments need to be received in our office by 5 p.m. the last business day of the month, postmarks are not accepted for tax liens.
