In any school district in which mines net profits are made a part of the total assessed value of taxable property, should the amount of such net profits certified as required by section 63-2803, Idaho Code, be lower in any year than for the immediately preceding year in an amount equaling five per cent (5%) or more of the total assessed value of taxable property of the district for the preceding year, then the state department of education shall compute the adjusted value of taxable property in the district for the purposes of section 33-1009, Idaho Code, by subtracting from the adjusted value of property in the district for the preceding year, the total of such decrease in mines net profits tax.
The county auditor of each county in which the net profits of mines are made a part of the total assessed value of taxable property of any school district, shall annually examine the reports of mines net profits certified to the county assessor as required by section 63-2803, Idaho Code, and shall certify to the state department of education not later than the fifteenth day of June of each year, the net profits of mines creditable to each school district in said county.
