How we calculate Illinois take-home pay
Illinois's flat 4.95% rate means high earners pay a lower effective state rate than in progressive states like California or Oregon. On a $150,000 salary, Illinois state tax is approximately $7,425 — compared to roughly $13,000 in Oregon or $10,000 in California. Illinois residents comparing job offers in other states should factor in both the tax rate and cost of living differences. Chicago's cost of living is moderate compared to coastal cities, which affects the real-world value of tax savings from relocation.
