Morgan County property tax deadline is Monday, payment options outlined

Morgan County property owners have until Monday, June 22, to pay the first installment of their 2025 tax-year bills, and Crystal Myers is urging residents not to let the Juneteenth holiday disrupt their plans. Payments can be made online, by mail, at the courthouse drop box on the north entrance, or at most Morgan County banks, but not at US Bank.

The timing matters because the Morgan County Courthouse will be closed Friday, June 19, for Juneteenth, and most banks and the post office will also be closed. Myers said people mailing a payment close to the deadline should take it inside the post office so it gets a timely postmark. The treasurer’s office says mailed payments must be postmarked on or before the due date to avoid interest charges, and any payment postmarked after June 22 is considered late.

Illinois law adds a 1.5% per month-or-part-of-a-month penalty for overdue payments, and Morgan County’s schedule shows how quickly those charges can rise. Penalties begin June 23 at 1.5%, then increase to 3% on July 23, 4.5% on August 23, 6% on September 23 and 7.5% on October 23. That makes the first installment deadline especially important for households trying to avoid compounding costs later in the summer.

The county mailed property tax bills on May 22. Taxpayers who want to pay in person can use the treasurer’s office, which lists hours of Monday through Friday from 8:30 a.m. to 4:30 p.m., or the courthouse drop box outside the north entrance. The drop box is emptied daily by a courthouse employee, giving residents another option if they cannot get inside during regular business hours.

Residents can also use the county’s DevNet payment portal for online tax inquiry and payment, or mail checks to the Morgan County Treasurer’s Office at 300 West State Street in Jacksonville. For many households, the web portal or drop box may be the safest way to avoid a holiday-week delay.

The first installment is only part of the year’s bill. The second installment is due Tuesday, September 15, with penalties beginning September 16, and the county says separate bills are not mailed for that payment. Mobile home taxes for the 2025 tax year payable in 2026 are due July 22, adding another deadline taxpayers will need to track on their own.
