October 19, 2026

Illinois's rule, 820 ILCS 115/5, keys the deadline to your regular payday. In full: At the time of separation if possible, otherwise next regular payday. Pick the separation type, enter the last day and your next payday, and the calculator returns the latest date you can legally pay. Accrued PTO payout is a separate Illinois rule and is not included. Related: the Illinois minimum wage, the HR compliance risk check for the termination process, and the all-state calculator. Nearby: Indiana, Wisconsin and Missouri.
