Moving from Illinois to Florida

IL → FL

Illinois to Florida is one of the best-documented state-to-state relocation corridors in the country -- Florida is consistently Illinois's single largest destination for outbound movers, and IRS migration data even points to the specific Florida counties (Lee, Pinellas, Collier, Sarasota) where Illinois households land most often. But this corridor's real financial story is genuinely different from the more commonly discussed New York or Massachusetts exits, and this record does not flatten it into the same shape. Illinois's income tax is a real, moderate flat 4.95% -- nowhere near a dramatic top-bracket cliff -- and Illinois already fully exempts Social Security, pension, and 401(k)/IRA income from state tax for retirees who stay, so the income-tax savings from this move are real but modest for most retirees. The dominant, best-documented driver instead is property tax: Illinois ties New Jersey for the highest average effective property tax rate in the nation (1.88%, running well above that even in Cook County), against Florida's 0.79% statewide average. And in a finding this record states plainly rather than smoothing over, composite cost-of-living indices reviewed this pass actually put Illinois BELOW the national average and Florida modestly above it -- meaning this move does not lower a typical mover's overall cost of living on a statewide basis, the opposite of what the generic 'expensive state to cheap Florida' narrative would predict.

The numbers

Zillow Home Value Index (ZHVI), typical home value, statewide, June 2026 -- the single-methodology figure this project uses across every state for cross-state corridor comparisons.

Illinois's income tax is a real, moderate flat 4.95% on wages -- nowhere near the dramatic top-bracket cliffs New York's or Massachusetts's corridors carry, and this record does not oversell it as one. Critically, Illinois already fully exempts Social Security, pension, and 401(k)/IRA distribution income from state tax for retirees who stay in Illinois -- so a retiree moving specifically for income-tax reasons is often trading a $0 state tax bill on retirement income for another $0 state tax bill, not eliminating a real burden. The genuine income-tax delta from this move falls almost entirely on WORKING-age movers and on retirees with substantial non-retirement income (rental income, business income, capital gains), who do shed a real 4.95% state rate. This is a smaller, more targeted tax story than this corridor's property-tax story below.

This is Illinois -> Florida's real, dominant, and best-documented tax story -- not income tax. Illinois's statewide average effective property tax rate is tied for the highest in the nation, and Cook County specifically runs well above even that already-high statewide average. Florida's 0.79% statewide average is less than half Illinois's 1.88% figure, and a Cook County property owner paying toward the 2.0%-2.7% end of that county's range sees a far larger drop still. Both statewide averages mask real county-level variation on both ends -- Florida's larger coastal counties run above the Florida state average too -- so this is directionally reliable but not a precise per-parcel promise.

This is the single most important honest disclosure in this file, and this record states it plainly rather than forcing the generic 'expensive state to cheap Florida' narrative that fits the NY and MA corridors but does not fit this one. Every composite cost-of-living index reviewed this pass put Illinois BELOW the national average (94.7-96.4) and Florida modestly ABOVE it (102.2-102.8) -- meaning Florida runs more expensive than Illinois on a pure statewide cost-of-living-index basis, not less. This is driven substantially by Illinois's own genuinely affordable statewide housing market (see illinois.js's own housing figures) outweighing Illinois's higher property tax and sales tax in these composite indices. Category-level detail available this pass: Florida housing costs roughly 21% more than Illinois's, groceries roughly 10% more, and restaurants roughly 13% more; Florida runs cheaper specifically on childcare (roughly 30% less) and transportation (roughly 6% less). A prospective Illinois mover should not assume this move lowers their overall cost of living on a statewide basis -- the real, documented financial case for this corridor rests on property tax and income tax, not a blanket cost-of-living win, and this record does not manufacture one where the data does not show it.

How many people actually make this move

35,262 people moved from Illinois to Florida in 2022.

Florida is consistently, well-documentedly Illinois's largest single destination state for outbound movers -- multiple metrics corroborate this from different angles rather than one clean number. The 2022 Census ACS-vintage figure (35,262) is the most consistently corroborated single-year gross flow found this pass. A separate, more recent secondary-source figure cited roughly 24,400 Illinois-to-Florida movers in 2024 alongside a distinct, smaller net-loss figure (11,659) described as Illinois's largest net loss to any single state that year -- these are different metrics (gross flow vs. net loss) from different sourcing chains that this record does not collapse into one number. IRS Statistics of Income (SOI) county-to-county migration data adds real, specific texture the Census state-level figure does not: roughly 4,617 Illinois households a year land in the specific Florida counties IRS SOI tracks, concentrated in Lee, Pinellas, Collier, and Sarasota counties -- real, county-specific data this record uses directly to inform which Florida cities this file recommends in content.destinationCitiesToConsider, rather than defaulting to Florida's largest, most generic metros. Separately, IRS SOI reports Illinois lost 28,609 income tax filers and $6 billion in adjusted gross income to interstate migration (all destinations) in the 2022-2023 filing year, while Florida gained 55,349 filers and $20.6 billion in AGI nationwide -- corroborating context, not an Illinois-to-Florida-specific figure. census.gov itself was unreachable in this research environment; all figures above are secondary-source corroborations of Census/IRS data, not a direct primary-source refetch.

What actually changes

Property tax drops sharply and is the clearest, most consistently documented change in this corridor: from Illinois's nation-tying 1.88% statewide average effective rate (higher still in Cook County, commonly 2.0%-2.7%) to Florida's 0.79% statewide average. Income tax drops from Illinois's flat 4.95% to Florida's constitutional 0%, a real but comparatively modest change for most movers given Illinois's rate is neither especially high nor especially punishing to begin with, and given Illinois already exempts retirement income entirely for those who stay. Climate flips from Illinois's real four-season, snow-and-freeze winter (most severe in Chicago and the state's northern third) to Florida's subtropical-to-tropical climate with no winter freeze risk, but this also trades one real severe-weather risk for a different one -- Illinois's currently escalating tornado exposure (202+ confirmed tornadoes in 2026, a national record-adjacent total) for Florida's six-month hurricane season. What does NOT clearly change, and this record states this honestly: overall cost of living. Every composite index reviewed this pass showed Florida running modestly above Illinois, not below it, driven substantially by Illinois's own genuinely affordable statewide housing market.

Climate

Illinois: cold-temperate, four true seasons, regular winter snow and freezing temperatures -- most severe in Chicago and the state's northern third, more moderate near the Metro East/Greater St. Louis region

Florida: subtropical to tropical depending on region; no winter freeze risk across nearly all of the state

What to watch out for

The property-tax and income-tax savings are real, but a mover expecting a broad cost-of-living win on top of them should recalibrate that expectation -- the data reviewed this pass does not support it on a statewide basis, though a specific Cook County-to-Florida move likely still nets a real overall savings once the property-tax gap is large enough to outweigh Florida's modestly higher composite index. Florida's homeowners insurance is the other side of the ledger this record does not let the tax savings obscure: florida.js's own sourced range runs $3,240 to $10,384/year depending on coverage and location, driven by a hurricane season Illinois simply does not have -- Illinois's own homeowners-insurance costs, by contrast, are rising due to a real, escalating tornado/derecho risk, but from a lower base ($2,402-$3,108/year per sources reviewed for Illinois). Retirees specifically should run the actual numbers before assuming this move is primarily a tax play: Illinois already fully exempts Social Security, pensions, and 401(k)/IRA distributions from state tax, so a retiree's genuine income-tax delta here is often smaller than the delta a New York or Massachusetts retiree would see leaving those states. And Illinois's own pension-debt and credit-rating story ($143.5 billion in unfunded state pension liabilities, the only state above $100 billion, even after a real October 2025 Moody's upgrade to A2) is a real, disclosed structural fact about the state a mover is leaving, separate from the property-tax figure that more directly drives this specific relocation decision.
