The Wisconsin law allows employers to deduct payments from an employee’s paycheck under certain circumstances. Oftentimes, an employer can withhold a portion of the worker’s wages to satisfy an order from a government agency or a court. These deductions may be approved in regards to child support, a student loan, or unpaid income taxes.
However, employers are not allowed to withhold any amount from an employee’s paycheck to reimburse the costs of employer-mandated medical tests. Furthermore, any deduction caused by poor workmanship and stolen or lost property is deemed unlawful if the employee fails to authorize the deduction in writing, unless the employee is found at fault in court for negligence or willful misconduct. The deduction is also only lawful if the employer and a representative assigned by the employee deem that the damage, loss, or theft has been a result of employee negligence or willful misconduct.
