Paying Taxes

Via mail or in-person:

The Town of Thornton only accepts cash or checks in the office. Credit and Debit card transactions may be processed by individuals via an on-line payment kiosk. Please see “Pay Taxes on-line” on the Tax Collector home page of this website for further information. Payments may be made Monday through Thursday 8:00am to 4:00pm and Friday 8:00am to 3:30pm.

When paying taxes via mail or in-person at the office, please submit the bottom payment stub from your tax bill with the payment. A Balance Due Statement or other notice from the Tax Collector office will also suffice.

If you require a receipt for your payment, please present the entire bill and the bill will be stamped with receipted payment information. If you require a receipt for a payment made via mail, a postage-paid return envelope must be provided.

If the bill, a Balance Due Statement or other notice from the Tax Collector office is not available when making your payment, please be sure to indicate your property identification number (aka map/lot number) as well as the property location on the memo line of your check. Please do not indicate invoice numbers, as these number change for each billing cycle and the property identification always stays the same.

By providing these items, this will help prevent delays in posting & ensure posting accuracy of your payments.

Safe and Secure
  • Your information is kept confidential & is 100% secure, backed by the highest security standards. At no point during the payment process will the municipality be in possession of your electronic check or debit/credit card information.
  • Once you press Pay Now you are indicating you wish to pay for a given transaction (or transactions) and you are directed to the secure web site of the payment processor. The payment processor provides the electronic payment systems required to safely process and store financial information. The payment processor validates your ACH information or card number and expiration date, obtains authorization from the bank or card issuer, and issues you a confirmation number at the end of the payment transaction in order to complete the transaction.
  • Payment information updates may take 3-5 business days to appear on tax kiosk, as the municipality cannot process the payment until their bank clears the payment to their account.
How does it work?
  • When you make a payment using an electronic check (ACH) from your checking or savings account the non-refundable service fee is typically a flat fee for the transaction.
  • When you make a payment using a credit or debit card the non-refundable service fee is typically a percentage-based fee. The service fee is automatically calculated based upon the type of credit card used and the dollar amount of the bill being paid and is shown on the payment page before you submit your payment for processing.
  • There may also be fees imposed by the payment processor for returned payments, in addition to any fees your bank may charge you.
  • The service fee is a non-refundable fee added to an invoice to cover various administrative costs of the service provider associated with billing and accepting payment. In most retail scenarios, the cost to you of using a credit card is transparent to you as the fee has already been absorbed by the merchant and added by the merchant into the prices for all of the merchant’s products and services.
  • This fee is not received by the municipality.  Your municipality is not permitted to accept these fees.  As such, the administrative costs associated with processing these transactions appear as an added service fee to the processor not the municipality.

If you do not wish to be charged a service fee you can always mail a check to the Tax Collector or you can pay in person using cash or check.
