Wisconsin paycheck calculator, 2026
Wisconsin uses a four-bracket schedule with a standard deduction that phases out as income rises, which pushes the effective rate up faster than the brackets alone would suggest. Allowances are claimed on Wisconsin's own WT-4 form. Our 2026 figures are still being cross-checked, so this page shows the rules and sources rather than an estimate.

This is an estimate of payroll withholding, not tax advice, and not a prediction of your final tax bill. Withholding is what your employer sends in during the year; what you actually owe is settled when you file.
