A few things you should know before you enter this site. The Treasurer's office does not charge a fee, however the credit processing company will charge a convenience fee for each transaction made. If you choose to use a credit card the convenience fee will be 2.75% of the tax amount with a minimum convenience fee of $3.25. If you use a debit card the convenience fee will be $4.35 per transaction.
The site will walk you through an eleven step process. The first part of the site allows you to select the parcel (s) you wish to pay, and will give you the option to pay either the half or full tax amount. Please note that if you have more than one parcel, you should query the site using your name. All parcels assessed under the name entered should display. You should then select the parcels you wish to pay. This will be considered one transaction. If using a credit card you will be charged 2.75% of the total tax amount being paid.
If at any time you do not wish to proceed, you may exit the site and your payment will not be completed. However, if you submit the payment you will receive a confirmation that your payment was successfully completed along with a payment confirmation ID number. You should print this page for your records. If you wish to cancel a tax payment made through the website you will need to contact (719) 937-7672.
