Second Installment tax payments are generally due in late summer or early fall.

At this time, for the Tax Year 2020 Second Installment, assessment appeals have been completed, and the state equalization factor has been released by the Illinois Department of Revenue. Once the Assessor's Office calculates the exemption values and the Clerk's Office calculates the tax rates for each agency, our office will post the Tax Year 2020 Second Installment tax amounts online at www.cookcountytreasurer.com and announce the due date. Shortly thereafter, the Tax Year 2020 Second Installment tax bills will be printed and mailed.
