What the state says
Does the state tax personal income?
The official code text imposes an Iowa individual income tax: section 422.7 defines net income as the adjusted gross income before the net operating loss deduction with the listed adjustments, and section 422.13 states when an individual is required to make and file a return.
Active duty pay
Section 422.7(29) subtracts, to the extent included, all pay received by the taxpayer from the federal government for military service performed while on active duty status in the armed forces, the armed forces military reserve, or the national guard.
Stationed outside the state
Section 422.8(2) allocates and apportions income for a nonresident so that Iowa tax reaches the portion of net income allocable to Iowa, and section 422.7(29) subtracts federal military pay for active duty service without regard to where the service is performed.
Combat pay
The Department of Revenue states, under Combat Zone Pay, that income excluded by the federal government is also excluded for Iowa income tax purposes and gives combat zone pay as the example because it is excluded for federal income tax purposes. It states that Iowa follows the federal treatment of the military adjustments to gross income under the federal Military Family Tax Relief Act of 2003. The retrieved code sections state no separate combat zone provision.
Military retirement pay
Section 422.7(20) subtracts, to the extent included, retirement pay received by a taxpayer from the federal government for military service performed in the armed forces, the armed forces military reserve, or the national guard, and states that this exclusion is in addition to any exclusion provided under subsection 19.
Survivor benefits
Section 422.7(21) subtracts, to the extent included, amounts received as survivor benefits by a taxpayer from the federal government pursuant to 10 U.S.C. § 1447 et seq.
Guard and Reserve
Section 422.7(29) covers pay for active duty status in the armed forces military reserve and the national guard, section 422.7(28) subtracts military student loan repayments received while serving on active duty in the national guard or armed forces military reserve or on active duty status in the armed forces, and section 422.7(26) subtracts withdrawals from qualified retirement plan accounts where the taxpayer or the taxpayer's spouse is a member of the Iowa national guard or reserve forces ordered to national guard duty or federal active duty and states that no state penalty is assessed on such withdrawals.
Military spouses
The Department of Revenue states that under the Military Spouses Residency Relief Act of 2009, the Veterans Benefits and Transition Act of 2018 and the Veterans Auto and Education Improvement Act of 2022, the spouse of a service member may be exempt from Iowa income tax on income from services performed in Iowa where the spouse is not an Iowa resident. It states the three MSRRA conditions, the VBTA election to use the same residence as the member, and the 2022 Act election among the residence or domicile of the member, the residence or domicile of the spouse, or the permanent duty station of the member. It states that other income such as interest or rental income is included in a nonresident spouse's Iowa income and may be taxed in Iowa, and that a spouse claiming the exclusion checks the appropriate box on the IA W-4, enters the claimed state of domicile and attaches a copy of the spousal military identification card.
Filing
Section 422.13 states when a resident or nonresident individual is required to make and file an Iowa return, by reference to net income thresholds and to the tax computation in the chapter.
Withholding
Section 422.16 requires every withholding agent and every employer to deduct and withhold Iowa tax from wages paid, and to file and remit as the section provides. The Department of Revenue states the military-specific mechanics: a resident member claiming the active duty exclusion provides an IA W-4 to the payer of the income claiming exemption from withholding on active duty pay, and a spouse claiming the spousal exclusion checks the appropriate box on the IA W-4, enters the claimed state of domicile or residence and attaches a copy of the spousal military identification card.
Local taxes
Local taxes may matter here
The official code text establishes two local layers computed from Iowa individual income tax: section 298.14 provides for an instructional support and educational improvement income surtax imposed by a school district and collected with the state individual income tax, and chapter 422D authorises a county to impose an income surtax for emergency medical services. The Department of Revenue states, citing Iowa Administrative Code rule 701—304.1, that the school district surtax is applicable for resident members of the armed forces of the United States living in an Iowa school district, even where the member is not physically present in Iowa on the last day of the tax year. A local layer therefore sits on top of the Iowa individual income tax and the department states expressly that it reaches resident service members.
This covers local income tax only, and only as far as the source we cite goes. We do not look up individual cities, counties or school districts.
