2020 Taxes Payable in 2021

Tax notices are typically mailed near the end of January, to the owner of the property. Tax amounts will not be available until we have received and processed the tax roll from the Assessor– usually around mid-January.

If you prepaid your property taxes, we have answers to some frequently asked 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 (please note COVID-19 restrictions at the top of this page), 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. Checks and money orders should be made payable to “Boulder County Treasurer.”
