  "summary": "True monthly cost of a nanny including employer payroll taxes.",
  "description": "A nanny's stated hourly wage is not what you pay. As a household employer, you owe employer-side Social Security and Medicare (7.65% combined), federal unemployment tax, and usually state unemployment tax, on top of the wage itself. This calculator turns an hourly rate and weekly hours into a true monthly cost including those legally required employer taxes, plus optional overtime for hours worked over 40 in a week, which federal law requires for household employees. It also flags when your total cash wages cross the 'nanny tax' threshold ($2,700 for 2024, adjusted yearly) that triggers these obligations in the first place.",
  "formula": "Weekly wage = (regular hours × rate) + (OT hours × rate × 1.5); employer tax = wage × (7.65% + FUTA/SUTA rate); monthly cost = (weekly wage + employer tax) × 4.33.",

    {
      "q": "Do I really have to pay 'nanny tax'?",
      "a": "If you pay a household employee $2,700 or more in cash wages in 2024 (threshold adjusts yearly), you owe employer Social Security and Medicare taxes and likely federal/state unemployment tax, reported via Schedule H on your 1040. Misclassifying a nanny as a 1099 contractor to dodge this is one of the most commonly flagged household-employment issues in an IRS audit."
    },
    {
      "q": "Is overtime really required for nannies?",
      "a": "Yes. Nannies are non-exempt household employees under the Fair Labor Standards Act, so hours over 40 in a workweek must be paid at 1.5x the regular rate. Live-in nannies have different rules in some states, so check your state labor department."
    },
    {
      "q": "How does a nanny payroll service change this?",
      "a": "Services like Care.com HomePay or Poppins Payroll typically charge $40-60/month and handle tax filings, but they don't change the underlying tax math — add their fee to the 'benefits' field to see the fully loaded cost."
    },
    {
      "q": "Can I pay the employer taxes with pre-tax dependent care FSA funds?",
      "a": "No — FSA funds reimburse the actual care expense (wages), not your employer tax liability. Run the wage portion through a dependent care FSA calculator separately."
