How Illinois taxes your paycheck
Illinois has a flat 4.95% income tax for tax year 2026. Before the rate applies, the calculator subtracts a personal exemption of $2,925 per filer ($5,850 for a married couple). The personal exemption is not available once income passes $250,000 for single filers, $500,000 for married couples and $250,000 for heads of household. The calculator applies this using your taxable wages as the income figure.
Traditional 401(k) contributions are excluded from Illinois taxable wages, and Section 125 health premiums are excluded.
Figures are from Illinois DOR: 2026 personal exemption allowance (tax year 2026).
