This calculator estimates paycheck results by factoring in regular wages, overtime, other earnings, employee 401(k) contributions, and an optional employer match. It then applies estimated federal withholding, Illinois income tax withholding, Social Security, Medicare, and Additional Medicare to provide an approximate net pay amount.
Because 401(k) contributions are generally treated as pre-tax for federal income tax purposes, they may reduce taxable wages for those calculations. In Illinois, 401(k) contributions may also reduce taxable wages for state income tax withholding purposes in many payroll situations. However, they do not reduce Social Security or Medicare wages.
Illinois does impose state individual income tax, so this estimate includes Illinois income tax withholding. The calculator uses a flat Illinois withholding rate applied to taxable wages, along with any applicable exemptions and additional withholding amounts, to help provide a more realistic estimate.
Important Notes
This calculator is intended for informational and planning purposes only. Results are estimates and may not reflect every situation, payroll setup, deduction, or tax election. Actual paycheck amounts can vary based on your employee’s withholding elections, year-to-date wages, Illinois withholding elections, benefits, and other payroll factors.
