The Treasurer’s Office collects taxes for real property, mobile homes, and business personal property (business equipment).
On July 1, 2020, the Treasurer became the Public Trustee
The Treasurer is now the Public Trustee. When a real estate loan is paid, the Public Trustee releases the deed of trust, conveying ownership of the property to borrower. The Public Trustee also manages foreclosures ensuring the rights of borrowers and lenders are protected.
If you have any questions, you can contact our office at 303-441-3520, or by email at eforeclosures@bouldercounty.org (foreclosure-related questions) or trustee@bouldercounty.org (general questions).
Paying Taxes
Our online and telephone systems are no longer available for paying this year’s taxes. Taxes must be paid by mail or in our office with certified funds– cash, cashier’s check, or money order. Contact us to ensure you pay the correct amount. If you choose to mail us a payment, do not include cash. Checks and money orders should be made payable to “Boulder County Treasurer.”
Although online payments are no longer being accepted, you can still lookup your taxes and view receipts online.
