How Illinois paychecks are taxed
Illinois withholds a flat 4.95% after subtracting your IL-W-4 allowances: $2,925 for each Line 1 allowance (usually 1 for yourself, more for a spouse or dependents) and $1,000 for each Line 2 allowance (age 65+ or blind). The allowance total is spread across your paychecks. Pre-tax 401(k) and health deductions also reduce Illinois wages.
Federally, employers use the IRS percentage method (Publication 15-T, 2026), plus 6.2% Social Security up to $184,500 of wages and 1.45% Medicare (another 0.9% on wages over $200,000).
