Limits and Important Notes

How the Illinois Paycheck Calculator Works

The calculator annualizes taxable regular wages and subtracts $2,925 for each entered Illinois exemption allowance plus any additional state deduction.

It multiplies the nonnegative balance by 4.95% and divides by the selected number of pay periods.

Formula

Illinois withholding = max(0, annual taxable wages − allowances × $2,925 − state deduction) × 4.95% ÷ pay periods

Example

For $52,000 annual taxable wages and one allowance, estimated Illinois withholding is ($52,000 − $2,925) × 4.95% = $2,429.21 annually.

The separate $1,000 Line 2 allowance mechanism is not modeled as a distinct field; use additional state deduction if applicable.
Reciprocity, nonresident workdays, special credits, supplemental wages, and employer benefits may change payroll.
The estimate is not an Illinois income-tax return or official payroll calculation.
