Budget Act Article 72

At the end of the fiscal year, the revenues that have already accrued, but have not been received by an agency, shall be carried over to the next fiscal year as accounts receivable; the use of the allocations that have not been used shall immediately cease. However, for the obligations or contractual responsibilities that have already occurred, but not yet repaid or released, it maybe carried over to the next fiscal year as accounts payable for the previous year or expenditure encumbrances subject to approval.

但已發生而尚未清償之債務或契約責任部分,經核准者,得轉入下年度列為以前年度應付款或保留數準備。
