- Your Iowa taxable income from all sources, IA 1040, line 4, is less than $5,000 and you are claimed as a dependent on another person’s Iowa return. For purposes of this condition, none of the income listed above is required to be added back to the Iowa taxable income.

Nonresidents and Part-Year Residents: In addition to the exemption provisions above, if you were a nonresident or part-year resident and had Iowa source net income of less than $1,000 (see note below) you are exempt from Iowa tax. For a description of “Iowa-source income”, see the instructions for the IA 126, lines 1 through 26. If you had Iowa taxes withheld and are requesting a refund, or choose to file an Iowa return even though you aren’t required to do so, you must complete the entire IA 1040 and the entire IA 126.
Note: If you were a nonresident or part-year resident and subject to Iowa lump-sum tax (even if Iowa-source income is less than $1,000), you are required to file an Iowa return reporting the lump-sum tax even if you have no regular Iowa income tax liability.

Married Separate Filers:
Married taxpayers filing married filing separately must use the combined income of both spouses in determining eligibility for exemption from tax.
If either spouse has a net operating loss that is carried forward, then the other spouse cannot use the low income exemption. If the spouse with the net operating loss chooses not to carry the loss forward, then the other can claim the low income exemption. A statement must be included with the return saying that the spouse with the net operating loss will not carry it forward.
