Employers must provide all requested documentation as it pertains to the paid family and medical leave program. If an employer fails or refuses to provide necessary payroll or other wage information during an audit, the department may determine payroll and wage information for the purposes of premium assessment based on information otherwise available to the department. This may include information from the same employer, similar employers, labor market information, information provided to other state or local agencies, or the best information otherwise available to the department.
