When Are Property Taxes Due in Illinois?
Illinois property taxes are billed the year after assessment in two installments, but the exact dates depend on the county. Cook County differs sharply from the rest of the state.
Dates vary by locality
Due dates are set at the county level and differ significantly. Cook County uses accelerated billing: the first installment (55% of the prior year's bill) is due around March 1, and the second installment is due later in the year (often August, but the date shifts year to year). The other 101 counties typically use a two-installment schedule with the first installment due around June 1 and the second around September 1, though each county board sets its own dates (and if bills are mailed late, the first installment is due 30 days after the bill date). Owners must check their county treasurer.
If you pay late: Delinquent installments accrue interest at 1.5% per month (statutory) on the unpaid amount until paid.
