🌴 COUNTRY A California VS 🌆 COUNTRY B Illinois

It depends on income level. At $100,000 income, Illinois saves $106/year (CA ~4.9% effective vs IL 4.95% flat, about 4.8% effective after the exemption). At $500,000 income: IL saves $18,950/year. However, earners below roughly $97,000 pay more in IL than in CA, because California's lower brackets are lighter than a 4.95% flat rate. Property taxes favor CA at average effective rates—on a $1M home, about $7,000/year at CA's 0.70% average vs $18,800/year at IL's 1.88% (difference of $11,800/year). A recent California buyer pays more than the average, because Prop 13 sets the base tax at 1% of assessed value (about $10,000 on a $1M purchase) plus voter-approved local charges.

Illinois is tied with New Jersey for the highest property tax rate in the US (1.88%) because it relies on property taxes to fund schools, municipalities, and massive public pension obligations. Chicago/Cook County rates are 2.0-2.5%. Illinois has one of worst-funded pension systems in US, driving up property taxes. California's Prop 13 limits the base property tax rate to 1% of assessed value (set at the purchase price and rising at most 2% a year until the next sale), plus voter-approved local charges.

California wins for tech workers: Silicon Valley/SF offer highest salaries in world ($250k-$500k+ total comp for senior engineers), best career growth, stock options worth millions. However, Chicago has growing tech scene with a generally lower cost of living and lower income tax (4.95% flat vs CA's marginal rates of 9.3% and up at those salaries). Choose CA for career max, IL for cost savings.
