Every employer required to deduct and withhold the tax under Section 13020 of the code from the wages of an employee is liable for the payment of such tax whether or not it is collected from the employee by the employer. If the employer deducts less than the correct amount of tax, or fails to deduct any part of the tax, he or she is nevertheless liable for the correct amount of the tax.
