How This Calculator Works

Calculation methodology and assumptions

Wisconsin's withholding guide offers flat percentages for supplemental payments as an alternative to combined-pay methods. The percentage depends on estimated annual gross salary. The prefill is the guide's 5.30% tier for salaries from $25,520 to under $280,950; it is not a determination of your employer's method.

Frequently Asked Questions

Is 5.30% the only Wisconsin supplemental rate?

No. The guide lists different flat percentages by estimated annual gross salary and also describes combined-pay methods. Ask payroll which applies to your payment.

Does the calculator know my annual gross salary?

No. Earlier wages are used for payroll tax calculations; they do not select the Wisconsin tier. Set the state percentage to match your payroll estimate.
