A taxpayer’s right to file a complaint pursuant to § 8-8-25 for review of a final decision of the tax administrator ordering an assessment, deficiency, or otherwise shall be conditional upon prepayment of all taxes, interest, and penalties set forth in the assessment, deficiency, or otherwise; provided, however, that in lieu of the prepayment, the taxpayer may file together with his or her complaint a motion for an exemption from the prepayment requirement. The taxpayer shall set the motion down for hearing within twenty (20) days after the answer to the complaint is filed; otherwise, the motion shall be deemed to be denied. The court shall grant the motion if it determines both: (1) that the taxpayer has a reasonable probability of success on the merits; and (2) that the taxpayer is unable to prepay all taxes, interest, and penalties set forth in the assessment, deficiency, or otherwise. In making its determination on the issue of ability to prepay, the court shall consider not only the taxpayer’s own financial resources but also the ability of the taxpayer to borrow the required funds. If the motion is denied, the taxpayer shall make prepayment within thirty (30) days of the entry of the court’s order denying the motion; otherwise, the complaint shall be dismissed upon motion of the tax administrator.
