Work in Nebraska, Live in Iowa: How Both States Tax You

Reciprocity

Do Nebraska and Iowa have a tax reciprocity agreement?

No. The Iowa Department of Revenue states that Iowa's only income tax reciprocal agreement is with Illinois, so there is nothing that exempts an Iowa resident's Nebraska paycheck from Nebraska tax. Both states claim the same wages, for different reasons:

• Nebraska taxes a nonresident who has income derived from or connected with Nebraska sources, and its regulations list compensation for services among those sources.
• Iowa taxes its residents on all income and then gives back the overlap through an out-of-state tax credit.

The result for a Council Bluffs resident with an Omaha job is two state returns every year, with the credit on the Iowa side doing the work of preventing a double bill.

Filing

Which tax returns do I file?

Do the Nebraska return first. Nebraska's booklet tells nonresidents to put total federal AGI on line 5 of Form 1040N, not just the Nebraska income, and to attach Schedule III even if all income was earned in Nebraska. Schedule III then computes the tax on your whole income and multiplies it by a ratio of Nebraska income to total income.

When you file the IA 1040, Iowa asks you to include each IA 130 and the income tax return you filed with the other state. If you also had income taxed by a third state, Iowa wants a separate IA 130 for each state.

Wages are not the only thing Nebraska counts. The Schedule III instructions list income such as severance pay associated with Nebraska employment, business income, rent and royalty income and lottery prizes, and Nebraska's regulation says owning an interest in real property located in Nebraska is enough to make the income from it Nebraska source income.

Credit

How does the Iowa credit prevent double taxation?

The IA 130 compares two numbers and gives you the smaller one:

• Iowa's tax on the Nebraska income. Line 17 divides the income taxed by Nebraska by your total Iowa income, and line 19 applies that percentage to your Iowa tax balance.
• The Nebraska tax you actually paid on that income, entered on line 20.

The line 17 percentage is rounded to the nearest ten-thousandth of a percent and cannot exceed 100%, so a commuter whose only income is Nebraska wages lands at 100%. Nebraska's Schedule III ratio works the same way from the other side: it is calculated to six decimal places, rounded to five, and capped at 100%.

Line 23 takes the smaller of line 19 or line 22 and moves it to IA 1040 line 15. Iowa's instructions add that the credit must not exceed the Iowa tax imposed on the same income. In practice the Nebraska wages end up taxed at whichever state's bill is higher: if Nebraska's tax is larger, Iowa's tax on those wages drops to zero; if Iowa's is larger, you pay Nebraska in full and Iowa collects the difference.

Remote Work

Does Nebraska tax the days I work from home in Iowa?

Possibly, which makes this the corridor's trickiest question. Nebraska's income tax regulation contains a convenience of the employer clause: if a nonresident's work is performed outside Nebraska for the nonresident's convenience, but is tied to a Nebraska business and could have been done in Nebraska, the pay for it is Nebraska source income.

LB 1023 (2024) changed how this works for tax years beginning on or after January 1, 2025. Nebraska's 2026 employer guide describes the new limits:

• Convenience-rule pay counts as Nebraska sourced income if the nonresident also performs services in Nebraska for more than seven days during the year.
• For a remote worker with seven employment duty days or less in Nebraska, none of the wages are subject to Nebraska withholding.
• Above seven days, the employer withholds Nebraska tax only on wages for work performed while present in Nebraska.
• Wages for a Nebraska conference or training can be excluded when you are present and earning wages in Nebraska seven days or less that year, those Nebraska wages total $5,000 or less, and you work in more than one state.

Partial days in Nebraska count as full days. Keep a dated log of where you worked, and read Nebraska's current guidance before deciding how much remote pay to report on Schedule III.

Withholding

How should my Nebraska employer withhold?

Your employer withholds Nebraska income tax using your Form W-4N. If you completed a federal W-4 in 2020 or later but never filed a W-4N, Nebraska tells the employer to withhold as if you were single with no allowances.

If you split time between Nebraska and Iowa for the same employer, you can file Form 9N, the Nebraska Nonresident Employee Certificate for Allocation of Income Tax Withholding. It sets the percentage of your wages subject to Nebraska withholding. That percentage only drives withholding; it does not decide the Nebraska wage figure on your W-2 or your final Nebraska tax.

A Nebraska employer normally withholds only Nebraska tax. When Nebraska's tax on your wages is at least as large as Iowa's, the IA 130 credit wipes out Iowa's share and nothing more is due. When Iowa's tax is larger, for example because of Iowa income that Nebraska does not tax, the estimated tax rules below decide whether you need to prepay it.

Worked example: Iowa resident with a $70,000 Omaha salary

Single filer, tax year 2026, standard deductions, no other income or adjustments. Nebraska tax estimated with its 2026 estimated tax rate schedule. Iowa exemption credits are left out because the IA 130 credit clears the Iowa balance either way.

Estimated Tax

Do I need estimated payments to Nebraska or Iowa?

Nebraska requires estimated payments from every resident and nonresident whose Nebraska income tax, after personal exemption credits, is expected to exceed withholding and other credits by $500 or more. A commuter with normal W-4N withholding on a Nebraska paycheck usually stays under that line. Remote workers whose employer stops Nebraska withholding under the seven-day rule should check it, since the withholding rule does not by itself settle what is reported on Schedule III.

Iowa requires estimated tax from taxpayers who expect to owe $200 or more on income not subject to withholding, a threshold that rises to $1,000 for tax years beginning on or after January 1, 2026. For a Nebraska commuter, the Iowa exposure usually comes from income the IA 130 credit does not reach, such as interest, dividends, rents or an Iowa side business.

Iowa installments for calendar-year filers are due April 30, June 30, September 30 and January 31, and payments can be made on GovConnectIowa.

Local Tax

Does Iowa's school district surtax apply to my Nebraska wages?

Only to whatever Iowa tax is left after the credit. On the IA 1040, the out-of-state credit reduces your tax on line 15, line 18 is the balance after nonrefundable credits, and line 19 multiplies line 18 by your school district's surtax percentage. If the IA 130 credit brings line 18 to zero, the surtax is zero as well.

The district that counts is the one you lived in on December 31, not the one your children attend, and the surtax applies whether or not you have children. You can look up your district in the Iowa Tax Mapper using the school surtax option. A few counties add an emergency medical services surtax through the same line; Iowa lists Appanoose, Cass, Pocahontas, Sac, Shelby and Winnebago.

Moving

What if I move between Iowa and Nebraska during the year?

A move makes you a partial-year resident of Nebraska and a part-year resident of Iowa. Nebraska says domicile is established on the date you arrive for other than temporary or transitory purposes, and partial-year residents also use Schedule III. On the Iowa side, IA 1040 line 13 holds the nonresident or part-year resident credit through the IA 126, and the IA 130 has separate lines for part-year residents.

The December 31 rule also decides the surtax. If you moved out of Iowa before year end, you enter district code 9999 and owe no school district surtax. If you moved into Iowa, you enter your new district and may owe it.

Rates

What tax rates apply in 2026?

Nebraska rates for 2026 are 2.46%, 3.51% and 4.55%, with the third and fourth brackets both at 4.55%. The 2026 standard deduction is $8,850 single and $17,700 joint, and each personal exemption credit is $176. For a single filer, Nebraska's 2026 estimated tax schedule applies 2.46% up to $4,130, then $101.60 plus 3.51% up to $24,760, then 4.55% above that.

Iowa taxes all levels of 2026 taxable income at a flat 3.8% under Senate File 2442. Iowa taxable income starts from federal taxable income, so the federal standard deduction ($16,100 single for 2026) flows into the Iowa figure.
