The Employment Development Department in California has been particularly aggressive in the area of independent contractor reclassification audits. In the eyes of the Employment Development Department, California businesses have been abusing the system by treating workers who should be classified as employees as independent contractors. In doing so they shift the burden for payroll taxes onto the worker and avoid their own contributions to the payroll tax and unemployment insurance system. As a result, the Employment Development Department has been particularly vigilant in auditing businesses for perceived abused of the system. Often these independent contractor reclassification audits can be costly for businesses.
