Moving to Illinois
Moving to Illinois in 2026 means landing in a state with a genuine tax split worth understanding up front: a simple, moderate flat 4.95% income tax on wages, a property-tax burden tied for the highest average effective rate in the nation, and a sales tax that swings from 6.25% to a real Chicago high of 10.25% depending on where you shop -- plus a Chicagoland region that is genuinely not one market and a record-breaking 2026 tornado season worth budgeting insurance around.

Illinois levies a flat 4.95% tax on wage income -- straightforward, and neither the lowest nor the highest rate built in this project. The real, substantial fact working-age movers should budget around is property tax: Illinois's statewide average effective rate (1.88%, per Tax Foundation's 2026 figure) ties New Jersey for the highest in the nation, running meaningfully higher still in Cook County (commonly 2.0%-2.7% depending on municipality and overlapping taxing districts). Retirees face a genuinely different calculation -- see the retiring topic.
Confirm your specific target municipality's combined sales tax rate
Illinois's 6.25% state base sales tax rate gets a real, jurisdiction-set local add-on across 567 separate taxing jurisdictions, producing a statewide average combined rate around 8.86% and a real Chicago high of 10.25% (6.25% state + 1.75% city + 1.25% Cook County + 1% Regional Transportation Authority transit surcharge) -- one of the highest combined rates of any major US city. Confirm your specific target municipality's current rate directly.
Know which Illinois you're moving to
"Moving to Illinois" means genuinely different things depending on destination. Chicago anchors a roughly 9.4-million-resident metro built on a diversified, Fortune-500-dense economy -- but the North Shore's affluent, Northwestern-adjacent identity, the western suburbs' family-suburb 'Tri-Cities' corridor (Naperville regularly lands on national best-places lists), and the more affordable southwest suburbs are genuinely different destinations from each other. Downstate is likewise several separate regions: the Champaign-Urbana/Bloomington-Normal college-town corridor is a real, current growth story; Rockford carries an honest post-manufacturing recovery identity; the Metro East is genuinely oriented toward St. Louis rather than Chicago; and Springfield carries a distinct Lincoln-heritage capital identity. Confirm which region a job offer or cost estimate actually describes before assuming it applies statewide.
Prepare for real, current Illinois weather risk -- tornadoes and derechoes, not hurricanes
Illinois carries no hurricane risk (landlocked apart from its Lake Michigan shoreline) -- but 2026 was one of the most active tornado seasons on record nationally, and Illinois became just the second state ever (after Texas) to record more than 200 confirmed tornadoes in a single year, plus a damaging August 11, 2026 derecho across the state's north. This is a real, current, escalating homeowners-insurance cost driver worth budgeting for directly -- see the homeowners-insurance and climate-weather topics.
Key takeaways
- Illinois's flat 4.95% income tax is simple and moderate; its statewide average effective property tax rate (1.88%) ties for the highest in the nation and is the bigger budgeting factor for working-age movers.
- Illinois's sales tax is not one number -- confirm your specific target municipality's combined rate (6.25% to Chicago's 10.25% high).
- Confirm which Illinois region a job or home search actually describes -- Chicago's North Shore, western suburbs, and southwest suburbs, plus Rockford, the college-town corridor, Metro East, and Springfield, are genuinely distinct markets.
- Illinois recorded 202+ confirmed tornadoes in 2026, the second-most of any state in a single year ever -- confirm current homeowners-insurance costs directly.
