Illinois Hourly Paycheck Calculator

Illinois payroll taxes

Typical Illinois paychecks include federal income tax, Social Security, Medicare, and Illinois state income tax. Illinois does not impose city or county income taxes on employee wages (separate business or license taxes may exist but are not payroll withholdings). Employers fund Illinois unemployment insurance (SUTA) and FUTA. Pretax benefits—401(k)/403(b)/457(b), HSA, FSA, commuter, and certain insurance premiums—can reduce taxable wages when plan-eligible.

• Employee (federal): Income tax (W-4 based), Social Security, Medicare, Additional Medicare for high earners.
• Employee (state): Illinois income tax withholding (per IL-W-4 elections).
• Local income taxes: None on wages in Illinois.
• Employer: Illinois SUTA; FUTA; workers’ compensation as required.
• Pretax deductions: May lower federal/state taxable wages and, when eligible, FICA.

How Your Illinois Paycheck Works

Your net equals gross hourly wages (regular, overtime, tips, differentials, bonuses) minus pretax deductions; then minus FICA, federal income tax, and Illinois state withholding. Because Illinois has no local wage tax, there is no city/county withholding line. The calculator shows hours, rates, taxable wages, withholdings, deductions, and take-home.

• Inputs: Hourly rate, hours, overtime, tips, pay frequency, filing status, dependents/credits, pretax/post-tax deductions.
• Outputs: Itemized FICA, federal, Illinois state, deductions, and estimated net pay.
• Supplemental wages: Compare flat vs. aggregate federal methods for bonuses/commissions.

Replace placeholders with official Illinois Department of Employment Security (IDES) figures before publishing (taxable wage base, experience-rated range, new-employer rate).

Illinois salary threshold

Illinois generally follows the federal Fair Labor Standards Act (FLSA). Exempt status requires passing the duties tests and meeting the federal salary-basis threshold; job titles alone do not determine exemption. Confirm Illinois minimum wage, tip-credit rules, and industry-specific exceptions when classifying roles and computing overtime.

Illinois Federal Insurance Contributions Act(Fica)

FICA is federal and applies in Illinois: employees pay Social Security and Medicare; employers match both. Above a federal threshold, Additional Medicare tax is withheld from employees (no employer match). Eligible pretax benefits (e.g., Section 125 health premiums) can reduce FICA-taxable wages depending on plan rules.

Number of cities that have local income taxes

50-word description: Some U.S. municipalities levy wage or income taxes in addition to state and federal withholding. Rates, wage bases, and residency/worksite rules vary. Illinois does not require employee local income tax withholding (e.g., Chicago has no city wage tax). Always verify for multistate workers before estimating take-home pay.

Which form controls my Illinois state withholding?

Illinois Form IL-W-4 controls state withholding elections. Complete it with your IRS W-4. Update after life changes and mirror settings in the calculator for accuracy.

How should I enter overtime, shift differentials, tips, and bonuses?

Add overtime using the correct multiplier (typically 1.5× after 40 hours). Enter shift differentials, tips, and supplemental wages separately so the calculator recomputes withholding correctly.

Why did my Illinois paycheck change this period?

Common reasons: variable hours/tips, overtime, bonuses (supplemental withholding method), updated W-4/IL-W-4 elections, benefits changes, or federal/state tax-table updates. Compare current vs. prior pay stubs.

Can pretax benefits increase my take-home?

Yes. Eligible pretax deductions—401(k)/403(b)/457(b), HSA, FSA, commuter, and certain insurance premiums—reduce taxable wages and may lower income tax and, when eligible, FICA.

How are tips treated in Illinois paycheck calculations?

Reported tips are taxable for federal income tax, Social Security, Medicare, and Illinois state income tax. Include tips to ensure correct withholding and minimum-wage compliance where tip credits are used.

How do multiple jobs affect my withholding?

Use the IRS multiple-jobs guidance on your W-4 and ensure your IL-W-4 reflects your situation. Model each job separately to avoid under-withholding across employers.

What is Additional Medicare tax and when does it apply?

After wages exceed the federal threshold, employers must withhold Additional Medicare on the excess. There is no employer match for this portion; it appears alongside regular Medicare on your stub.

Are bonuses and commissions taxed differently?

They are supplemental wages. Employers may use a flat federal supplemental rate or aggregate with regular wages; Illinois state withholding applies either way. Enter amounts separately to compare methods.

Can the calculator project annual take-home from my hourly rate?

Yes. Multiply weekly hours by 52, add expected overtime/tips/bonuses, then run the estimate with your pay frequency and deductions to see an approximate annual net total.
