Clinton County Treasurer's Office

Payments can be made online– if paying by e-check, the cost is only 50 cents, less than the cost of a stamp. Debit and credit cards do have a 2.5% fee that the County cannot waive, as the fee is charged by the third-party vendor who processes the payment. Effective January 1, 2023, there will be a minimum Service Fee of $2.00 to those paying by credit and debit cards. 


Due to delays in bank processing times we strongly recommend that Canadian Taxpayers obtain money orders when remitting tax payments or utilize the online credit card/e-check option where available.  This will prevent additional penalties / interest being assessed due to delays. 

Canadian customers please note we only accept US postmarks.
