e-Check and Credit Card Payments

Certified funds are now required for all delinquent tax payments. Online tax payments have been disabled for the remainder of the year. You may still view tax account information, including copies of receipts, online.

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?

If you pay with an e-check, there is no charge to you for the service. Our processor charges a fee for card payments.
It’s easy to pay online. Just click the button below!
