Idaho Code § 33-801A

The board of trustees of any school district may create and establish a general fund contingency reserve within the annual school district budget. Such general fund contingency reserve shall not exceed five per cent (5%) of the total general fund budget, or the equivalent value of one (1) support unit computed as required by section 33-1002, Idaho Code, whichever is greater. Disbursements from said fund may be made by resolution from time to time as the board of trustees determines necessary for contingencies that may arise. The balance of said fund shall not be accumulated beyond the budgeted fiscal year. If any money remains in the contingency reserve it shall be treated as an item of income in the following year’s budget.
