Illinois vs Florida: take-home pay comparison

Illinois flat 4.95% state income tax against Florida's zero — Midwest-to-Florida retire comparison.

Illinois is one of the few US states with a flat (not progressive) state income tax — 4.95% on AGI above the personal exemption. Florida has no state income tax. For any salary level, the delta is essentially 4.95% × (gross − federal-standard-deduction).

At $80,000 gross the delta is ~$3,200/year in favour of Florida; at $200,000 it is ~$9,200; at $500,000 it is ~$24,000. The retire-to-Florida arbitrage and the "remote-work from FL while keeping an IL employer" pattern both lean on this comparison. FL property tax + insurance + cost of living vary substantially by area and are not modeled here.
