    How Illinois taxes hourly pay

    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.

    Hourly workers pay the same taxes as salaried staff. What changes is that your check moves with your hours, so withholding moves with it: a week with overtime is withheld as if every week looked like that.

    Questions

    How much is $20 an hour after taxes in Illinois?

    About $1,295.81 every two weeks ($647.91 a week) for 40 hours a week, single, W-4 defaults, 2026 rules. That's about $33,691 a year.

    How is overtime taxed in Illinois?

    Overtime is taxed like regular pay, but a check with overtime is annualized as if you earned that much every period, so more is withheld from that check. At $20 an hour with 10 overtime hours in a two-week period, take-home is about $1,522.01 instead of $1,295.81. Any new federal deduction for overtime is claimed through W-4 Step 4(b) or on your tax return.
