Iowa Code § 444.3: Computation of rate.

When the valuations for the several taxing districts shall have been adjusted by the several boards for the current year, the county auditor shall thereupon apply such a rate, not exceeding the rate authorized by law, as will raise the amount required for such taxing district, and no larger amount. For purposes of computing the rate under this section, the adjusted taxable valuation of the property of a taxing district does not include the valuation of property of a railway corporation or its trustee which corporation has been declared bankrupt or is in bankruptcy proceedings. Nothing in the preceding sentence exempts the property of such railway corporation or its trustee from taxation and the rate computed under this section shall be levied on the taxable property of such railway corporation or its trustee.
