Iowa Code § 28A.17

(1) If an authority is established as provided in section 28A.6 and after approval of a referendum by a simple majority of votes cast in each metropolitan area in favor of the sales and services tax, the governing board of a county in this state within a metropolitan area which is part of the authority shall impose, at the request of the authority, a local sales and services tax at the rate of one-fourth of one percent on the sales price taxed by this state under section 423.2, within the metropolitan area located in this state. The referendum shall be called by resolution of the board and shall be held as provided in section 28A.6 to the extent applicable. The ballot proposition shall contain a statement as to the specific purpose or purposes for which the revenues shall be expended and the date of expiration of the tax. The local sales and services tax shall be imposed on the same basis, with the same exceptions, and following the same administrative procedures as provided for a county under sections 423B.5 and 423B.6. The amount of the sale, for the purposes of determining the amount of the local sales and services tax under this section, does not include the amount of any local sales and services tax imposed under sections 423B.5 and 423B.6.

(2) The treasurer of state shall credit the local sales and services tax receipts and interest and penalties to the authority’s account. Moneys in this account shall be remitted quarterly to the authority. The proceeds of the tax imposed under this section shall be used only for the construction, reconstruction, or repair of metropolitan facilities as specified in the referendum. The local sales and services tax imposed under this section may be suspended for not less than a fiscal quarter or more than one year by action of the board. The suspension may be renewed or continued by the board, but the board shall act on the suspension at least annually. The local sales and services tax may also be repealed by a petition and favorable referendum following the procedures and requirements of sections 28A.5 and 28A.6 as applicable. The board shall give the department of revenue at least forty days’ notice of the repeal, suspension, or reinstatement of the tax and the effective dates for imposition, suspension, or repeal of the tax shall be as provided in section 423B.6.
