Nannies in Greenwich cost $18-$30 per hour. Live-in nannies cost less per hour but include room/board. Agency placement fees are typically one month's salary.

A Greenwich nanny agency handles background checks, reference verification, CPR/First Aid certification verification, and matching families with qualified caregivers. Agencies pre-screen candidates so you interview only vetted nannies. Placement fees are typically one month's salary, which covers the screening process and a replacement guarantee.

Nannies provide one-on-one attention in your home, flexible scheduling, and can handle household tasks. Daycare offers socialization, structured learning, and consistent care even if a provider is sick. For families with two or more children, a nanny can be more cost-effective than paying for multiple daycare spots in Fairfield County — do the math for your specific situation.

Hiring a household employee in CT comes with legal obligations. You must verify the nanny's right to work using USCIS Form I-9, obtain an Employer Identification Number (EIN) from the IRS, and pay the "nanny tax" — which includes withholding and remitting federal and state payroll taxes (Social Security, Medicare, federal and CT income tax). Families who pay a household employee $3,000 or more in a calendar year (2026 threshold) must file Schedule H with their federal tax return. Many families work with a payroll service like SurePayroll or HomePay to handle compliance. A nanny agency can walk you through the requirements during placement.
