e-Check and Credit Card Payments

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.

e-Check and Credit Card Payments

We have partnered with Official Payments to offer payment of property taxes electronically.

You can pay your taxes online or over the phone with:

  • Electronic checks (e-checks)
  • American Express
  • Discover
  • MasterCard
  • Visa
  • Debit cards

In our office, we accept personal and business checks, cash, cashier’s checks, and money orders, as well as credit and debit cards.

Is there a fee?

Please note, our processor has increased these fees from the amounts listed on the tax notice sent this year.

If you pay with an e-check, there is no charge to you for the service.
Our processor charges a fee for card payments:

  • debit cards: 1.15% (minimum $1.15)
  • credit cards: 2.85% (minimum $4.50).

It’s easy to pay online. Just click the button below!


If you choose to mail us a payment, do not include cash. Checks and money orders should be made payable to “Boulder County Treasurer.”
