The Piatt County Treasurer's Office is now offering convenient online Real Estate tax payments through the GovTech Tax Collection and Escrow System.

We will begin accepting payments once the tax bills are mailed.

Piatt County tax bills are scheduled to be released the week of June 15, 2020.

If you should have received your tax bill and did not receive it, please contact the Piatt County Treasurer’s office at (217-762-4866). Failure of a taxpayer to receive a tax bill does not relieve them of their tax liability.

Taxes may be paid at any bank in Piatt County, by mail (Piatt County Treasurer, PO Box 116, Monticello, IL 61856), in person at the Treasurer’s office (M-F 8:30 AM to 4:30 PM) in the Piatt County Courthouse, Room 101, 101 W Washington St, Monticello, IL , or by credit card on line at and click on the link “Online Real Estate Tax Payments”. A convenience fee is charged by the credit card company for on line payments and is detailed at this link. With all payments, other than on line payments, the payment coupon attached to the bottom of the tax bill must accompany the payment.

Contact the Piatt County Treasurer’s office (217-762-4866) with any questions.
