Piatt County tax bills in the mail

Piatt County tax bills are scheduled to be mailed out this week. The first installment will be due July 20, and the second installment is due September 8.

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.

If your mailing address has changed, please contact the Supervisor of Assessments office (217-762-4266) with your address change. It is the taxpayer’s responsibility to report any mailing address changes to the Supervisor of Assessments office. Any questions on assessments or exemptions should be directed to the Supervisor of Assessments office.
