Frequently asked
- Do I owe nanny tax in Montana?
- 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. Montana state unemployment kicks in once you exceed the state's wage threshold — typically the first $47,300 of wages.
- What is the Montana SUI rate for a new household employer?
- New household employers in Montana start at 1.7%, applied to the first $47,300 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 Montana nanny?
- Montana uses progressive tax brackets. Your employee's state income tax withholding depends on their expected annual wages and filing status per their state withholding certificate. CareTax's calculator handles bracketed withholding automatically for every pay run.
- What forms do I need to file for a household employee in Montana?
- 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 Montana: 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 Montana state portals.
