§ 55. Employer's liability for withheld taxes.-- Every employer required to deduct and withhold tax under this local law is hereby made liable for such tax. For purposes of assessment and collection, any amount required to be withheld and paid over to the administrator, and any additions to tax, penalties and interest with respect thereto, shall be considered the tax of the employer. Any amount of tax actually deducted and withheld under this local law shall be held to be a special fund in trust for the city. No employee shall have any right of action against his employer in respect to any moneys deducted and withheld from his wages and paid over to the administrator in compliance or in intended compliance with this local law.
