Notification: The burden of proof rests with the employee to show the correct California income tax withholding. Pursuant to section 4340-1(e) of Title 22, California Code of Regulations (CCR) (govt.westlaw.com/calregs/Search/Index), the FTB or the EDD may require an employer to submit a Form W-4 or DE 4 when such forms are necessary for the administration of the withholding tax programs.
Penalty: You may be fined $500 if you file, with no reasonable basis, a DE 4 that results in less tax being withheld than is properly allowable. Criminal penalties apply for willfully supplying false or fraudulent information or failing to supply information requiring an increase in withholding.
