701—302.2(422) Interest and dividends from federal securities. For individual income tax purposes, the state is prohibited by federal law from taxing dividends from corporations owned or sponsored by the federal government, or interest derived from obligations of the United States and its possessions, agencies, and instrumentalities. Therefore, if the federal adjusted gross income of an individual, taxable by Iowa, includes dividends or interest of this type, an adjustment must be made by deducting the amount of the dividend or interest. If the inclusion of an amount of income or the amount of a deduction is based upon federal adjusted gross income and federal adjusted gross income includes dividends from corporations owned or sponsored by the federal government, or interest derived from obligations of the United States and its possessions, agencies, and instrumentalities, a recomputation of the amount of income or deduction must be made excluding dividends or interest of this type from the calculations.
A federal statute exempts stocks and obligations of the United States Government, as well as the interest on the obligations, from state income taxation (see 31 U.S.C.S. Section 3124(a)).
“Obligations of the United States” are those obligations issued “to secure credit to carry on the necessary functions of government.” Smith v.	Davis (1944) 323 U.S. 111, 119, 89 L.Ed.	107, 113, 65 S.Ct.	157, 161. The exemption is aimed at protecting the “borrowing” and “supremacy” clauses of the United States Constitution. Society for Savings v.	Bowers (1955) 349 U.S. 143, 144, 99 L.Ed.2d 950, 955, 75 S.Ct.	607, 608; Hibernia v.	City and County of San Francisco (1906) 200 U.S. 310, 313, 50 L.Ed.	495, 496, 26 S.Ct.	265, 266.
Tax-exempt credit instruments possess the following characteristics:
	1.	They are written documents,
	2.	They bear interest,
	3.	They are binding promises by the United States to pay specified sums at specified dates, and
	4.	They have Congressional authorization which also pledges the faith and credit of the United States in support of the promise to pay. Smith v.	Davis, supra.
A governmental obligation that is secondary, indirect, or contingent, such as a guaranty of a nongovernmental obligor’s primary obligation to pay the principal amount of and interest on a note, is not an obligation of the type exempted under 31 U.S.C.S. Section 3124(1). Rockford Life Ins.	Co.	v.	Department of Revenue, 107 S.Ct.	2312 (1987).
The following list contains widely held United States Government obligations, but is not intended to be all-inclusive.
This noninclusive listing indicates the position of the department with respect to the income tax status of the listed securities. It is based on current federal law and the interpretation thereof by the department. Federal law or the department’s interpretation is subject to change. Federal law precludes all states from imposing an income tax on the interest income from direct obligations of the United States Government. Also, preemptive federal law may preclude state taxation of interest income from the securities of federal government-sponsored enterprises and agencies and from the obligations of U.S. territories. Any profit or gain on the sale or exchange of these securities is taxable.

	302.2(2) Taxable securities. There are a number of securities issued under the authority of an Act of Congress which are subject to the Iowa income tax. These securities may be guaranteed by the United States Treasury or supported by the issuing agency’s right to borrow from the Treasury. Some may be backed by the pledge of full faith and credit of the United States Government. However, it has been determined that these securities are not direct obligations of the United States Government to pay a specified sum at a specified date, nor are the principal and interest from these securities specifically exempted from taxation by the respective authorizing Acts. Therefore, income from such securities is subject to the Iowa income tax. Examples of securities which fall into this category are those issued by the following agencies and institutions:
	a. 	Federal agency obligations:
	1.	Federal or State Savings and Loan Associations
	2.	Export-Import Bank of the United States
	3.	Building and Loan Associations
