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 $780 more per year in California than in Illinois ($58,805 vs $58,025, tax year 2026) — the entire gap comes from state tax, since federal and FICA are identical everywhere.

Where the ladder meets the flat ratethe winner can depend on salary

Illinois's single 4.95% rate meets California's 10-step ladder (up to 13.3%), and which system bites harder depends on where a salary sits. California leads at $75,000, but past about $100,000 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.
