For the purpose of determining what funds must be raised by taxes for county museum purposes, the county museum board shall meet at such time as may be provided by law for the preparation of budgets, and shall make a budget of the amounts required for museum purposes, including all salaries to be paid for the current year, and shall deduct therefrom any balance remaining in its treasury, and shall then certify to the board of county commissioners the amount of said budget. The board of county commissioners may make a levy upon all taxable property in the county in the amount requested by the county museum budget. No levy for the purposes of this chapter shall exceed three-hundredths percent (.03%) on each dollar of market value for assessment purposes of taxable property in the county. When such taxes have been collected, the same shall be paid to the treasurer of the county museum board to be used for the purposes authorized by this chapter. Upon the creation and appointment of the museum board by the county commissioners, it hereby becomes a taxing unit separate and distinct from any other taxing unit or tax levy within the county under the provisions of the Idaho budget law and as such is empowered to issue tax anticipation notes or warrants as provided by law for maintaining, carrying on, conducting, payment of obligations and all other necessary expenses, incurred or to be incurred in maintaining a museum. It may be the duty of the county commissioners of any county, where property for county museum purposes is located, to levy an amount sufficient to maintain and protect such museum grounds and property.
