Illinois Paycheck Calculator

Illinois Paycheck Calculator

The Illinois Paycheck Calculator on GCalculate.com is a free, intuitive tool designed for employees, employers, and HR professionals in Illinois to estimate net take-home pay after taxes and deductions. Tailored for both hourly and salaried workers, it calculates net pay by inputting gross wages, pay frequency (weekly, bi-weekly, semi-monthly, or monthly), filing status, and deductions. It accounts for Illinois’s flat state income tax rate of 4.95%, federal taxes, FICA (Social Security at 6.2% up to $168,600 in 2025, Medicare at 1.45%), and optional pre-tax deductions like 401(k) or health insurance contributions.

Users can input hourly rates and hours worked (including overtime at 1.5x for over 40 hours weekly) or annual salary to see how taxes and deductions impact their paycheck. The tool also supports Illinois’s reciprocity agreements with Iowa, Kentucky, Michigan, and Wisconsin, exempting non-residents from Illinois state tax if Form IL-W-5-NR is filed. A key feature is estimating how adjustments to W-4 or IL-W-4 forms affect withholdings, helping users optimize their take-home pay or tax refunds.

Accessible on any device without downloads, it integrates with payroll platforms like QuickBooks or Gusto for seamless use. For accuracy, verify gross pay, filing status, and deductions (e.g., HSA, FSA) against pay stubs or employer data, and consult a tax professional for complex scenarios.

Formulas:

• Net Pay = Gross Pay – (Federal Tax + Illinois State Tax + FICA + Other Deductions).

• Illinois State Tax = Taxable Income × 4.95% (after $2,850 exemption per person, 2025).

• FICA: Social Security = Gross Pay × 6.2% (up to $168,600); Medicare = Gross Pay × 1.45% (+0.9% for income >$200,000 single/$250,000 joint).

• Gross Pay (Hourly) = (Regular Hours × Rate) + (Overtime Hours × Rate × 1.5).

• Gross Pay (Salary) = Annual Salary / Pay Periods (e.g., 52 for weekly, 24 for semi-monthly).
