Any amount of tax actually deducted and withheld under this chapter shall be held to be a special fund in trust for the tax commission. No employee shall have any right of action against his or her employer in respect to any moneys deducted and withheld from his or her wages and paid over to the tax commission in compliance or in intended compliance with this chapter.
