Deep Dive: Each State
Illinois (IL)
Tax reality
Illinois has a flat 4.95% state income tax (moderate) — but property taxes are among the highest in the US, averaging 2.1% effective. On a $350K Chicago home that's $7,400/year. Combined tax burden is higher than it looks. The state's pension underfunding creates long-term fiscal risk for homeowners.

Top drawbacks
- ✕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.
Utah (UT)
Tax reality
Utah has a 4.55% flat state income tax (moderate). Property tax is low (~0.55% effective). Sales tax 4.85% state + local to 7-8%. No estate tax. Overall favorable tax environment.

Top drawbacks
- ✕Winter air quality in SLC is genuinely bad. Temperature inversions trap pollution in the valley for weeks at a time — SLC occasionally has worse AQI than Beijing. January-February air quality is a real health consideration.
- ✕Growth has been intense. SLC metro added 300,000+ people in the last decade. Housing prices followed: $2,050/mo 1BR, $560K median home — well above most people's 'Utah is cheap' mental model.
- ✕Traffic along I-15 during rush hour is a parking lot. The state has invested heavily in light rail (TRAX, FrontRunner) but most residents still drive.
