Understanding Each State
New York
New York's state income tax has progressive brackets reaching 10.9%. New York City residents pay an additional city income tax of 3.078-3.876%, making the combined state+city marginal rate up to 14.776% — the highest combined rate in the nation. The Yonkers surcharge adds another 16.75% of state tax for Yonkers residents.
Tip: If you work in NYC, the city income tax significantly increases your burden. Living outside the city (e.g., New Jersey, Connecticut, or Westchester) can save 3-4% on city tax, but commuter taxes and higher property taxes may partially offset the savings.
Illinois
Illinois has a flat income tax rate of 4.95% on all taxable income. While the rate is moderate compared to states like California or New York, Illinois's high property taxes (average ~2.08%, second-highest nationally) significantly increase the total tax burden, particularly for homeowners.
Tip: The flat 4.95% rate means your effective state tax rate is close to 4.95% regardless of income — no progressive bracket benefit. Property taxes in Cook County (Chicago) can exceed $6,000-$10,000 on a median-value home.
Key Comparison Points
Income tax structure: New York has a progressive income tax (3.9% – 10.9%), while Illinois has a flat income tax (4.95% flat).
Beyond income tax: State tax comparisons should also consider property tax rates, sales tax, and cost of living. A state with no income tax may have higher property or sales taxes that offset the savings.
SALT deduction cap: Under OBBBA, the 2026 federal SALT cap is $40,400, phasing out above $505,000 MAGI toward a $10,000 floor. This limits the federal tax benefit of living in a high-tax state, so the gross state tax difference remains close to the net difference for most earners — especially high earners inside the phaseout.
