Within 30 days from the date on which notice of supplemental assessment is sent by the board of assessment or Department of Finance or Department of Land Use, the owner may appeal the supplemental assessment to the respective board of assessment or board of assessment review. The appeal shall be scheduled and heard by the board during its next regular appeal period as provided in this title. Pending determination of such appeal, the owner may: (1) pay the tax imposed by the supplemental assessment, and if on appeal the assessment is reduced, the owner shall be entitled to a refund of the taxes which the owner has overpaid plus interest thereon at the rate of 1% per month; or (2) not pay the tax imposed by the supplemental assessment, in which case penalties shall accrue at the rate of 1% per month on the amount of taxes computed in accordance with the determination of the appeal, and no action to collect the tax shall be taken until the appeal is determined. Such interest and penalties shall begin to accrue upon the expiration of 3 months from the date on which the unpaid tax became due and payable. Interest attributable to the overpayment of school taxes shall be paid by the school board of the districts entitled to receive such taxes.
