Nanny Shares: How They Work, What They Cost, and How to Set One Up

What Is a Nanny Share?

A nanny share is an arrangement where two (or occasionally three) families hire a single nanny to care for their children together. The nanny typically rotates between the families' homes on a set schedule or works at one fixed location. Each family pays less than they would for a dedicated nanny, while the nanny earns more than a single-family position would pay. It is a win-win-win structure that has grown significantly in popularity, particularly in high-cost urban areas where both nanny and daycare costs are steep.

How Much Does a Nanny Share Cost?

In a standard two-family nanny share, each family pays approximately 60–75% of the full nanny rate. If a full-time nanny in your area earns $22/hour, each family in a share might pay $13–$17/hour. Here is a cost comparison for a 45-hour work week:

• Full-time nanny (solo): $22/hour = $990/week = $4,290/month per family
• Nanny share: $15/hour per family = $675/week = $2,925/month per family
• Nanny's total: $30/hour = $1,350/week = $5,850/month (a raise for the nanny)
• Center-based daycare: $1,200–$2,000/month per child (for comparison)

The savings versus a solo nanny are substantial — roughly $1,000–$1,500 per month per family. Compared to center-based daycare, a nanny share costs moderately more for one child but provides the in-home, personalized care that many parents prefer. For families with two children each, the math becomes even more favorable since nanny shares typically charge a modest per-child bump rather than doubling the rate.

Finding a Share Family

The most critical factor in a successful nanny share is compatibility between the families. Look for partners through:

• Local parent groups: Facebook groups, Nextdoor, and neighborhood parenting forums are the most common channels.
• Nanny share matching services: Platforms like NannyLane, Hazel, and some local agencies specialize in matching share families.
• Your existing daycare waitlist: Families on the same waitlist share a similar timeline and geographic area.
• Pediatrician offices: Some pediatricians maintain bulletin boards or referral networks for childcare.

When evaluating potential partners, discuss parenting philosophy, discipline approaches, dietary preferences, screen time rules, illness policies, vaccination requirements, and backup plans. The more aligned you are upfront, the smoother the arrangement will run.

Legal and Tax Considerations

Nanny shares create a unique employment situation. Each family is a separate employer, which means each family must independently handle payroll taxes, workers' compensation insurance, and year-end tax forms (W-2). Both families should:

• Obtain an Employer Identification Number (EIN) from the IRS
• Register as a household employer with your state
• Withhold and remit Social Security, Medicare, and applicable state taxes
• Provide workers' compensation insurance (required in most states)
• File Schedule H with your personal tax return

Using a nanny payroll service like HomePay, SurePayroll, or Poppins Payroll (approximately $50–$100/month per family) simplifies compliance enormously and is strongly recommended.

The Nanny Share Agreement

A written agreement between the two families (and the nanny) is essential. Key elements to include:

• Work schedule, including start and end times for each day
• Location rotation schedule or fixed hosting arrangement
• Compensation structure — each family's share, overtime policy, and payment schedule
• Paid time off, sick days, and holiday schedule
• Illness policy — when a child is too sick to participate and how backup is handled
• Termination terms — notice period and what happens if one family leaves the share
• Expense sharing for food, supplies, and activities

Common Challenges and How to Solve Them

The most frequent nanny share challenges include schedule conflicts (solve with a shared digital calendar and clear boundaries), one child being sick (establish a policy upfront — does the well family still send their child?), differing parenting styles (address proactively through honest discussion before signing the agreement), and the share ending when one family moves or no longer needs care (include a 30–60 day notice clause and a plan for transitioning to solo care).

Is a Nanny Share Right for You?

A nanny share is ideal for families who want the personalized, in-home benefits of a nanny at a lower cost, are comfortable with their child socializing closely with one or two other children, have a compatible family nearby with children of similar ages, and can handle the administrative requirements of being a household employer.
