clickable image for COVID closure infoEffective March 16, 2020, Jefferson County offices are closed to the public. Many offices will be providing services online. Please contact individual offices to learn more and visit the COVID Closure page for countywide closure information.

If you are looking to file a Business Personal Property Declaration Schedule, please file it electronically through our website rather than by mail if possible. Please only use one method of submission (either electronically or by mail, but not both). Please note that as of March 31, 2020, the State of Colorado Division of Property Taxation has not extended the filing deadline from April 15, 2020. 

During the closure of Jefferson County offices, all Jefferson County Assessor’s Office staff will be working from home. This means that we will continue most of our normal operations, and all departments will be available to answer questions via phone and email. We ask that you initially contact us via email, then we can set up a phone call if requested. 

To send us an email, please use our contact form.

Thank you for your patience and understanding.

Important Alerts for Tax Notices: 

  • We are currently processing documents that were recorded with the Jefferson County Clerk & Recorder in September 2019. Ownership changes that have occurred since then may not be reflected on Property Record Search results. Thank you for your understanding and patience.
  • If you bought a new property in 2019 and have not received your tax notice, your transfer probably has not been processed yet. The Treasurer’s Office will continuously mail out tax notices to new owners as the Assessor’s Office finishes processing them. The notice above will be updated to reflect our progress until all deeds through December 2019 are completed.
  • If you receive a tax notice for a property you sold in 2019, please disregard it. Once the ownership records are updated, the new owner will be notified of the taxes due.
  • If you did not receive a tax notice for property you owned before 2019, you may find the tax notice using the Treasurer’s Property Records Search Application. Please search by address or PIN/Schedule#, if known.

The Jefferson County Assessor’s Office provides quality customer service by being courteous, respectful and informative while identifying, describing and valuing all property within Jefferson County in a fair, ethical, accurate and professional manner.

The Assessor is available anytime to present the Re-Appraisal Valuation and Assessment Process.  Please contact the Assessor’s Office to schedule.
