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.

It is the taxpayer’s responsibility to report any mailing address changes to the Supervisor of Assessments office.
