Iowa Code § 360.2 - Tax

If a majority of the votes cast are in favor of the tax, the trustees shall certify such fact to the board of supervisors, and they shall thereupon levy a tax not to exceed the rate voted and not to exceed twenty and one-fourth cents per thousand dollars of assessed value each year for a period not exceeding five years on the taxable property of the township, except that such five-year limitation shall not apply in case of a public hall acquired by a lease with a purchase option. When such tax is collected by the treasurer, it shall be paid to the township clerk; but said clerk shall not receive to exceed one percent for handling said money.
