R.I. Gen. Laws § 44-30-77: Employer’s failure to withhold.

If an employer fails to deduct and withhold Rhode Island personal income tax as required, and thereafter the employee’s tax against which the tax may be credited is paid, the tax so required to be deducted and withheld shall not be collected from the employer, but the employer shall not be relieved from liability for any penalties, interest, or additions to the tax otherwise applicable in respect of the failure to deduct and withhold.
