Rhode Island General Laws Title 44. Taxation § 44-11-6. Determination and payment of tax due--Hearings and redeterminations

(a) At the time of the filing of the return, the taxpayer shall pay to the tax administrator the amount of the tax as computed by it on the basis of its net income under § 44-11-2(a) or other provision as applicable. As soon as possible after the filing of the return, the tax administrator shall determine the correct tax payable under this chapter by the taxpayer, and if the tax determined shall exceed the amount which the taxpayer has paid at the time of filing its return, the tax administrator shall mail to the taxpayer a notice of the additional tax due indicating the basis on which the tax was determined.

(b) If any taxpayer is not satisfied with the amount of tax determined, the tax administrator, upon being notified, in writing, within thirty (30) days from the date of the mailing of the notice, shall fix an early date at his or her office when the taxpayer can be heard to show cause why the tax should be changed, and after which the tax administrator may redetermine the amount of that tax.

(c) If it shall appear subsequent to the mailing of any notice that the amount of the tax was erroneously stated, the tax administrator shall mail a corrected notice and fix a day when the taxpayer can be heard.

(d) The additional tax required to be paid by any taxpayer shall be due and payable within thirty (30) days after the mailing of the notice or corrected notice by the tax administrator.
