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.
