If a district is organized in any year too late for the levy of a tax in that year or in the next ensuing year, the board is hereby authorized to transfer funds of the county not immediately needed for county purposes to the maintenance fund of the district to be used for the payment of the expenses of such district until such time as special assessment tax receipts are available therefor. The board shall include in the levy of taxes for the district for the first fiscal year in which a tax may be levied, a sum sufficient to repay to the county the amounts so transferred to the district for the portion or portions of the preceding fiscal year or years for which no levy of taxes was made for that purpose and the amounts so transferred shall be retransferred to the county treasury from the maintenance fund of the district out of the first available receipts from the tax levy.
