California Application For Earnings Withholding Order (CA kWh) testing is the process of verifying that the information and settings associated with the CA kWh is accurate and compliant with the California Employment Development Department (EDD) procedures and regulations. The purpose of the testing is to ensure that wage garnishments are properly deducted from an employee’s paycheck and that the proper amounts are being sent to the appropriate agencies. There are two types of CA kWh testing: initial setup testing and ongoing testing. Initial setup testing includes verifying that the correct information is entered into the form, such as employer information, employee information, and garnishment information. Ongoing testing includes verifying that the correct amounts are deducted from the employee’s paycheck and that the correct amounts are sent to the appropriate agencies.
