Illinois vs Oklahoma: Take-Home Pay (2026)
Same salary, two tax codes — computed for tax year 2026, single filer with standard deduction.
Quick answer
According to netpaytally.com's computations, a $75,000 salary keeps $738 more per year in Oklahoma than in Illinois ($58,763 vs $58,025, tax year 2026) — the entire gap comes from state tax, since federal and FICA are identical everywhere.
Illinois's single 4.95% rate meets Oklahoma's 4-step ladder (up to 4.5%), and which system bites harder depends on where a salary sits. Here the answer never flips: Oklahoma keeps more at every salary in the table, and the lead reaches $1,526 a year by $250,000. The federal share ($7,670 income tax, $5,738 FICA) cancels out of this comparison entirely.
