Illinois Paycheck Calculator 2026

Tax year 2026 · Last reviewed October 4, 2026

Use this Illinois net pay calculator to estimate your take-home pay. Illinois applies a flat 4.95% tax to modeled state taxable income. The calculator subtracts the applicable personal exemption before calculating that tax, then shows federal income tax and FICA separately.

How Illinois Paycheck Taxes Are Calculated

A flat rate does not mean 4.95% of every dollar in gross wages: the modeled personal exemption reduces Illinois taxable income. The rate does not rise with income as it does in progressive-tax states. Illinois does not add a general city or county income tax on wages.

How does Illinois tax compare to other states?
