What date and kind of change should you start with?
There are three different developments on this page. HFS refreshed its financial tables on March 20, 2026. A property-tax statute became effective July 10, 2026, with important rules tied to the tax certificate and deed dates. A child-support act approved in 2026 does not become effective until January 1, 2027. Treating all three as a single set of new 2026 rules would give the wrong starting point.
For your matter, identify the support period or tax certificate, the current order or notice, and the provision whose application is disputed. A search-result date or an article's year is not a substitute for that comparison.

Illinois HFS identifies March 20, 2026 as the effective date for its new income-shares amounts. The basic-obligation schedule and standardized gross-to-net table perform different jobs. One supplies a household support amount; the other assists with the tax calculation used to determine income. Neither eliminates review of the parents' legally appropriate adjusted net income, parenting schedule, expenses or special circumstances.
Our 2026 and 2027 child-support guide explains how to keep the current tables and the future shared-care law separate. The child-support page includes a limited arithmetic tool and preparation information.
In effect: the July 2026 property-tax law requires date-specific review
Public Act 104-0553 became effective July 10, 2026. Among its changes are a judicial tax-deed auction framework, surplus-equity provisions and changes to redemption rules. The Act contains applicability language. For example, changes to Section 22-40 apply to matters concerning tax certificates issued on or after the effective date.
The 2026 property-tax changes guide explains the date distinctions. If you already hold a notice, use the tax-sale notice checklist to organize the certificate, county records and court papers for prompt review. An article cannot determine your redemption expiration from an address alone.
Future law: shared-care support changes on January 1, 2027
Public Act 104-0733 changes the shared-care child-support framework beginning January 1, 2027. It introduces a 110-overnight threshold, qualifying overnight equivalents and percentage adjustments for some schedules below 146 overnights. These are future rules as of this guide's research date.
Do not use a 2026 illustration as a completed 2027 calculation. Likewise, the passage of a law does not by itself authorize a parent to replace an existing payment amount with a number from a website. Review the applicable modification process, the order and the governing date.
Current background rules are not automatically new 2026 laws
The ordinary maintenance guideline in 750 ILCS 5/504 remains a separate analysis of entitlement, income, amount and duration. This update does not identify a new 2026 replacement for that formula. The maintenance guide and calculator distinguish the standard net-income formula from a qualifying earlier-order gross-income formula.
Court calendars, remote-hearing instructions and a judge's assignment can also change without a new statute. Check the actual hearing notice and the court's official instructions when preparing to appear. A change to a meeting link is a court-process update, not a change to the substantive law discussed here.
What records make an update relevant?
- For support: the current order, income records, completed financial information, actual parenting calendar, benefit records and documented child-related expenses.
- For property tax: the PIN, tax certificate information, notices and envelopes, redemption estimate, court docket, deed and any auction or distribution records.
- For either issue: identify the decision you need to make, the next scheduled event and any date already stated in a notice or order.
Our family-law and civil and property-dispute service pages describe representation options. A consultation can focus on which version of a rule applies, the available next steps and the proposed scope of work. Fees and any ongoing arrangement depend on the written terms for the matter.
