Treasurer

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

Property taxes may be paid in full, or in two half payments, by the due dates. You can pay these taxes in our office, by mail, online, or over the phone. Instructions for each of these payment methods can be found on the back of your property tax notice. If you choose to mail us a payment, do not include cash.
