R.I. Gen. Laws § 1-6-2

There is imposed on all transient parking in the district a surcharge in an amount equal to five percent (5%) of transient parking receipts. The surcharge shall be collected by the operator of each facility providing transient parking in the district and remitted by the operator to the tax administrator not later than the twentieth (20th) day of the month following the calendar month in which the transient parking was provided. The tax administrator may require the filing of any forms with any information that the tax administrator may reasonably determine is necessary to carry out the provisions of this statute. The surcharges collected by the tax administrator under this section shall be deposited upon receipt in a special account, denominated as the Warwick airport parking district account. At annual or more frequent intervals, amounts accumulated in the Warwick airport parking district account shall be remitted to the treasurer of the city of Warwick to be held as part of the general fund of the city of Warwick.
