- Is overtime taxed more in Illinois?
- No. Overtime pay is taxed at the same income-tax rates as your regular wages — there is no special Illinois overtime tax rate. A large overtime check can have more tax withheld up front, because payroll systems briefly treat that paycheck as if you earned that much every period, but the extra withholding is reconciled when you file — the actual tax rate on overtime dollars is unchanged.
- Does Illinois have a state income tax?
- Yes. Illinois applies a flat 4.95% state income tax to taxable income. Illinois has no standard deduction; a personal exemption (about $2,925 per person in 2026) is modeled here instead.
- How accurate is this Illinois hourly paycheck calculator?
- It's a close estimate, but it doesn't model local (city/county) taxes, tax credits, or every deduction, and rates change over time. Your actual pay stub is the source of truth.
