Property tax bills in Sangamon County are due on June 5, according to a June 2 announcement. Bills were mailed in April, and payments received or postmarked after the due date will be subject to late fees.
The Treasurer’s office noted that recent changes at the United States Postal Service may delay timely delivery of tax payments. Taxpayers are encouraged to use various “Easy-Payment” options detailed on the Treasurer’s website at Sangamonil.gov/treasurer. These services are intended to help ensure timely payment and avoid issues related to postal delays.
During ongoing renovations at the County Building, the Treasurer’s office has returned to the first floor. The office recommends using “Easy-Payment” methods to avoid construction and parking challenges in Downtown Springfield. Those choosing to pay at the County Building should be prepared for parking issues and security screening.
