How Illinois Income Tax Works
Illinois uses a flat tax — unlike most states with graduated brackets. Every taxpayer pays 4.95% of taxable income. The only deduction is a personal exemption per person (plus dependents) — confirm the exact current-year amount with the Illinois Department of Revenue, as this session found inconsistent figures cited in different sources. There is no standard deduction comparable to the federal $16,100 (2026).
Illustrative example calculation on $75,000 (using a ~$2,750 exemption):
- Illinois taxable income ≈ $75,000 − $2,750 = $72,250
- Illinois tax ≈ $72,250 × 4.95% = $3,576
Note that Illinois does not tax Social Security or retirement income, which significantly reduces the tax burden for retirees compared to working-age residents.
