Quick answer
According to netpaytally.com's computations, a $75,000 salary keeps $38 more per year in Massachusetts than in Illinois ($58,063 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 Massachusetts's 2-step ladder (up to 9%), and which system bites harder depends on where a salary sits. Massachusetts leads at $75,000, but past about $200,000 the balance tips the other way as the ladder's top steps overtake the flat rate. The federal share ($7,670 income tax, $5,738 FICA) cancels out of this comparison entirely.
