We have discontinued online payment for the year and now require payment in certified funds. Payment can be made by mail or in our office with cash (office only), cashier’s check, or money order.

Our Lafayette office is now closed for the year. It will open again in late January, after tax notices have been mailed out. Please contact our office at 303-441-3520 with any questions.


Income tax and legal implications of prepaid property taxes

Our office cannot offer legal or financial advice. Seek advice from a lawyer or tax professional regarding whether your prepaid property taxes can be claimed as a deduction on your annual income tax returns. By accepting your payment, this office is not making a representation as to whether your tax payment will be deductible.

Additionally, while our office and other Treasurer’s Offices throughout Colorado have accepted prepayments for property taxes for several years, the Treasurer is not making any judgments whether it is legal for our office to be accepting such payments.

Prepayment terms

Prepayment is no longer being accepted for 2021 taxes payable in 2022.
