Caps and rules for local property taxes

The law limits how fast most covered local property tax extensions can grow. The cap is the lesser of 5% or last year’s CPI change, unless voters approve a higher increase. It sets a limiting tax rate formula that uses the prior aggregate extension base and the cap, divided by current EAV that excludes new property and recovered TIF value; if last year’s levy fell, it uses the highest of the last three years. Many debt and special‑purpose levies, like voter‑approved bonds, some pensions, and workers’ comp, do not count toward the cap. New construction and property coming off exemption count as “new property” and, like recovered value after a TIF ends, are kept out of the rate base. These rules apply to covered non‑home‑rule districts, including those in counties with 3,000,000+ people or next to them.

Relief and new deadlines on tax sales

In Cook County, the application for the 2018 tax sale cannot be filed until the first month with no statewide COVID emergency and no later than October 1, 2021. For delinquent 2023 warrant balances in Cook County, no interest accrues from September 2, 2025 through April 1, 2026. Cook County must file for judgment within 365 days of the second installment due date for tax years after 2017. If a tax sale was delayed by the statewide COVID emergency, the next annual sale must wait at least 180 days and a scavenger sale at least 90 days. In counties that adopted a Section 21-40 ordinance, the filing happens in December. In counties with fewer than 3,000,000 people, collectors must apply within 90 days after the second installment due date.
