The Clinton County Treasurer’s Office reminds residents that fall property tax installments are due Monday, November 10, 2025. Taxpayers have several convenient options for submitting their payments, including by mail, in person, online, or at a participating bank.
Mail Payments:
To pay by mail, enclose your tax coupon and check and send it to:
Clinton County Treasurer
2 East Washington Street, Suite 204
Frankfort, IN 46041
Mailed payments must be postmarked on or before November 10 to avoid late penalties. If you would like a receipt, please include a self-addressed, stamped envelope.
In-Person Payments:
Payments may be made in person at the Clinton County Treasurer’s Office, located on the second floor of the Annex Building. Office hours are Monday through Friday, 8:00 a.m. to 4:00 p.m.
A drop box is also available behind the building for check payments. Be sure to include your tax coupon with the payment.
Online Payments:
Residents can pay online at www.clintonco.com by selecting “Pay My Taxes Online.” Accepted methods include credit or debit cards and e-checks. Please note there is a 2.5% service fee for card payments and a $1.00 fee for e-checks.
Bank Payments:
Payments may also be made at First Financial Bank in Rossville during regular business hours. Taxpayers must bring their tax coupon and pay the exact amount listed.
The Treasurer’s Office reminds property owners that partial payments do not prevent late penalties, additional fees, or tax sale eligibility. To avoid penalties, ensure your full payment is received or postmarked by the due date.
