Nonresidents or Part-Year Residents:

A nonresident or part-year resident of Iowa must complete the IA 1040, lines 1 through 12 prior to completing the IA 126. The nonresident or part-year resident then completes a Schedule IA 126. On the IA 126, only Iowa income is reported and a percentage of Iowa income to total income is determined. The taxpayer receives a credit against the initial tax liability based on the percentage of income from outside Iowa. Therefore, the result of this credit is that only Iowa-source income is taxed.

Note: The Iowa income percentage is rounded to the nearest ten-thousandth of a percent in accordance with Iowa Administrative Code rule 701ā€”304.5. The final credit from this form is used to reduce the total tax on your IA 1040.

Although non-Iowa income is used to calculate the initial tax liability at the appropriate tax rate, the non-Iowa income itself is not subject to tax. By using this method, Iowa taxes the Iowa-source income of nonresidents and part-year residents at the same rate it taxes Iowa residents. Iowa, like many states and the federal government, uses a graduated tax rate system based on level of income.

A nonresident of Iowa with all-source income of $250,000 and $10,000 of Iowa income, will use the same tax rate as an Iowa resident with $250,000 of income to calculate their initial tax liability, rather than using the same tax rate as an Iowa resident with $10,000 of total income. Enter the amount of your nonresident / part-year resident tax credit from Schedule IA 126, line 33. A copy of Schedule IA 126 and a copy of your federal return must be included. You may owe less tax by using filing status 3 or 4.

Enter the amount of your nonresident or part-year resident tax credit from Schedule IA 126, line 32. A copy of Schedule IA 126 and a copy of your federal return must be included.

General instructions for completing the IA 126:

Part-Year Iowa Residents:

Iowa-source net income includes all income received while living in Iowa plus any Iowa-source income received while a nonresident.

Part-Year Resident Example:  Michael lived and worked in Iowa the first six months of the tax year. In addition to Michaelā€™s wages, Michael received interest income from an Iowa bank. Michael then permanently moved to Missouri, where Michael was employed for the rest of the year. Michael continued to receive interest income from the Iowa bank.

Michaelā€™s IA 1040, line 1, will report all of the income from both states as all-source income. On the IA 126, Michael will report the wages and interest income earned while an Iowa resident as Iowa-source income. The interest income earned the last half of the year is not considered Iowa-source income since Michael was no longer an Iowa resident

Nonresidents:

Iowa-source net income will include all income from Iowa sources. Complete IA 126, lines 1 through 13 using only income from Iowa sources.

Nonresident Example 1:  Nick is a resident of Nebraska and works in Iowa. Nickā€™s income includes wages earned in Iowa and interest income from a Nebraska bank. Nick will report the wages and interest on the IA 1040 as all-source income. Nick will list only the Iowa wages  on the IA 126 as Iowa-source income.

Iowa has a reciprocal agreement with Illinois, which means that wages and salaries are taxed by the individualā€™s state of residence. All income received from other Iowa sources (gambling, unemployment, etc.) is taxable to Iowa regardless of the personā€™s state of residence.

Nonresident Example 2:  Tiana is a resident of Illinois. Tiana earned $25,000 in wages from Iowa and won $5,000 at an Iowa casino. Tiana will report income from all sources on the IA 1040. Only the gambling winnings will be reported on the IA 126 as Tianaā€™s Iowa-source income.

Full-Year Residents (married jointly filers check the corresponding box if one spouse is a full-year Iowa resident)
For married taxpayers, if one spouse is a full year Iowa resident, the full year Iowa resident must include all of that spouseā€™s income from the IA 1040.

Married Separate Filers:

Divide your Iowa income between spouses using the instructions on each line of the IA 126 below.

Reporting Modifications to Iowa Source Income

If any income claimed on lines 1-12 are modified by any amounts claimed on IA 1040, Schedule 1, lines 1-11, net out those modifications directly on each applicable line. (Example: if you have Iowa-source wages of $50,000 but all wages were active duty military pay, and you claimed the active duty military pay modification on IA 1040, Schedule 1, line 6; enter $0 on IA 126, line 1). An exception would be K-1 Modifications listed on IA Schedule 1, line 3. See line 12 instructions for more information.

Part-year residents: Include all W-2 income earned or received while an Iowa resident, even if it was earned in another state, and any income for services performed in Iowa while a nonresident of the state. If it was earned in another state, you may also need to fill out the IA 130 if you pay tax to the other state. You will need to check with that state for their filing requirements.

Nonresidents: Report only Iowa-source income. If the portion of employee compensation earned in Iowa by a nonresident is not reported separately, allocate the compensation based upon the number of days worked in Iowa to total work days. Nonresidents who earned compensation in Iowa and one or more other states for a railway company, an airline company, a merchant marine company, or an interstate motor carrier are only subject to income tax on that income in their state of residence and should not include these wages on line 1.
