 Wisconsin Payroll Tax Withholding Information

  • Withholding – Wisconsin employers should use the following method to calculate supplemental wages.

    Wages between $0-$10910 withhold at 4%
    Wages between $10,910-$21,820 withhold at 5.84%
    Wages between $21,820-$240,190 withhold at 6.27%
