Medicaid and low-income coverage in Illinois
Illinois expanded Medicaid, so adults with income up to 138% of the poverty line (about $22,025 for one person or $45,540 for four) can usually get Medicaid instead of a marketplace plan. Starting in 2027, federal law requires most adults 19 to 64 in this group to show 80 hours a month of work, school or community service unless exempt; states may get extensions to 2028 (One Big Beautiful Bill Act (Pub. L. 119-21)).
Staying under the cliff
If your income is close to $63,840 (single) or $86,560 (couple), pre-tax 401(k), HSA and traditional IRA contributions lower the income the marketplace counts.
