Illinois

Key Comparison Points
Income tax structure: New York has a progressive income tax (4% – 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 (2025+), the federal SALT cap is $40,000, phasing out above $500,000 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.
