If, after all certificates of indebtedness drawn against any delinquent tax fund shall have been fully paid, there remains any balance in such fund, such balance shall be apportioned to the several funds for which money was borrowed in proportion to the total amount of taxes levied for each fund in such fiscal year, and such fund shall thereupon be terminated and all delinquent taxes for such year thereafter paid shall be apportioned to the funds for which the same were originally levied.
