What to Expect in Illinois
The honest trade-offs. People who move here usually don't regret it, but these are the things to plan for.
Property tax is brutal — Cook County averages 2.3% effective. On a $500K home, that's $11,500/year. Homeowners feel this every month.
Chicago winters are genuinely cold. Lake-effect snow, mid-December through March subzero streaks, and winds off Lake Michigan can make it feel -20°F. This is the biggest filter for people considering moving here.
The state fiscal situation (pension debt, budget pressures) drives ongoing policy uncertainty — property tax, sales tax, and various fees continue to drift upward.
Chicago has real public safety concerns in specific neighborhoods. Most downtown, North Side, and near-North are fine; West and South Side neighborhoods have higher violent crime rates.
Illinois is in long-term population decline — losing residents to Indiana, Wisconsin, and the Sun Belt. This affects state services and tax base.

Not legal advice. For complex situations (large capital gains, stock options, deferred comp), consult a tax CPA before moving.
