Frequently asked

Do I owe nanny tax in Iowa?
If you pay a household employee $3,000 or more in 2026, you owe federal FICA (Social Security and Medicare). If you pay $1,000 or more in any calendar quarter, you owe FUTA. Iowa state unemployment kicks in once you exceed the state's wage threshold — typically the first $20,400 of wages.
What is the Iowa SUI rate for a new household employer?
New household employers in Iowa start at 1%, applied to the first $20,400 of each employee's wages per year. Your rate can change once the state assigns you an experience rating, usually after 2–3 years.
How much state income tax do I withhold for a Iowa nanny?
Iowa applies a flat 3.8% state income tax. You withhold this from each paycheck after applying any state standard deduction or exemptions based on your employee's state withholding certificate.
What forms do I need to file for a household employee in Iowa?
Federally: Schedule H (filed with your personal Form 1040), W-2 and W-3 (given to your employee and filed with the SSA), and quarterly EFTPS deposits if your liability exceeds $1,000/year. In Iowa: new-hire reporting, quarterly SUI filings, and any required state income tax withholding returns. CareTax generates all federal reference documents and points you to the Iowa state portals.
