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.”
