Employee Obligations (Which Returns YOU Must File)

If you physically work in Iowa, file a nonresident Iowa return (tax rate: Flat 3.8%). Then file your Utah return and claim the TC-40S credit so you don't get taxed twice on the same income.

Employer Obligations (What Your Employer Must Withhold & Remit)

Register for withholding and unemployment from day 1. Unemployment applies to the first $38,200 of wages.

City & Local Income Taxes (Extra Filings Beyond the State Return)

None for nonresidents. Iowa school district taxes are residence-based only.
