Iowa Administrative Code Title 701 — Department of Revenue
Iowa Admin. Code r. 701—302.6(422) — Interest and dividend income
This rule applies to interest and dividends from foreign securities and securities of state and other political subdivisions. Interest and dividends from foreign securities and from securities of state and other political subdivisions are to be included in Iowa taxable Revenue income. Certain types of interest and dividends, because of specific exemption, are not included in income for federal tax purposes. To the extent such income has been excluded for federal income tax purposes, unless the term of income is specifically exempted from state taxation by the laws or constitutions of Iowa or of the United States, it must be added to Iowa taxable income.
