IL HB5172

Creates a shared physical care child support calculation for parents who each have 110 or more overnights per year with the child, multiplying the basic support obligation by 1.5 and offsetting each parent's share based on income percentage and time spent with the other parent

Establishes "overnight equivalents" allowing courts to count significant daytime parenting periods when a child does not stay overnight but is under a parent's direct care

Creates a rebuttable presumption that parents incarcerated for more than 180 days are unable to pay child support, which can be overcome with evidence of ability to pay during incarceration

Sets a rebuttable presumption of $40 per month minimum child support obligation per child for obligors with income at or below 100% of federal poverty guidelines for a single person

Includes a statutory adjustment table for shared custody arrangements with fewer than 146 overnights per year, with the shared care support amount capped at what would be ordered under basic guidelines
