(a) If a taxpayer pays taxes under protest, the taxpayer may bring suit in the superior court against the municipality for recovery of the taxes. If judgment for recovery is given against the municipality, or, if in the absence of suit, it becomes obvious to the governing body that judgment for recovery of the taxes would be obtained if legal proceedings were brought, the municipality shall refund the amount of the taxes to the taxpayer with interest at eight percent from the date of payment plus costs.
(b) If, in payment of taxes legally imposed, a remittance by a taxpayer through error or otherwise exceeds the amount due, and the municipality, on audit of the account in question, is satisfied that this is the case, the municipality shall refund the excess to the taxpayer with interest at eight percent from the date of payment. A claim for refund filed one year after the due date of the tax is forever barred.
(c) The governing body may correct manifest clerical errors at any time.
