Nanny Share Agreement Guide: Contracts, Costs & Setup for 2026

How Much Does a Nanny Share Cost?

Everyone wins: each family pays less than a solo nanny, and the nanny earns a higher total rate. See our nanny share cost breakdown for more detail.

Finding Your Share Family

• Local parenting groups: Facebook groups, neighborhood parent networks, and Nextdoor are the most common way families find nanny share partners.
• Nanny share matching apps: Platforms like Habyts and some features on Care.com help match families by location and schedule.
• Your existing nanny's network: If you already have a nanny, they may know families looking for shares.
• Neighborhood canvassing: Post on community boards at libraries, pediatrician offices, and playgrounds.

Compatibility Factors to Discuss Upfront

• Schedule alignment (same days/hours needed)
• Children's ages (within 12 months is ideal)
• Parenting philosophy (screen time, food, discipline)
• Location and commute willingness
• Budget expectations and payment structure

The Nanny Share Agreement: What to Include

A written agreement between both families (and the nanny) prevents misunderstandings. Cover these provisions:

• Schedule: Days, hours, start/end times, flexibility expectations
• Location: One host home, alternating homes, or split schedule
• Compensation: Total nanny rate, each family's share, overtime policy
• Payment method: How and when each family pays (same payroll service recommended)
• Holidays & PTO: Which holidays off, vacation days, how PTO costs are split
• Sick days: Nanny sick days, child sick days (does a sick child stay home?)
• Trial period: 2–4 weeks to evaluate the arrangement
• Termination: How much notice to exit, obligations when one family leaves
• Communication: Daily updates, group chat, weekly check-ins between families
• Discipline approach: Agreed-upon methods
• Food & supplies: Who provides what, allergies, dietary needs
• Emergency contacts: Both families' backup contacts and pediatrician info

Tax & Legal Considerations

• Both families are employers: Each family has a separate employment relationship with the nanny.
• Each family needs an EIN: Apply separately at IRS.gov for free.
• Payroll can be split or separate: Each family can use their own payroll service, or you can use one service that supports nanny shares.
• Workers' comp: Typically one family carries the policy; costs are split in the agreement.
• DCFSA eligible: Both families can use their Dependent Care FSA for their share of nanny costs.
• Each family files Schedule H: Report your portion of wages on your own tax return.

Common Nanny Share Challenges

• Schedule conflicts: One family's schedule changes can disrupt the arrangement. Build flexibility into the agreement.
• Different parenting philosophies: Discuss screens, food, discipline, and nap schedules before starting.
• Sick child logistics: Agree upfront whether a sick child stays home or whether the nanny cares for them separately.
• Uneven ages: A baby and a toddler have very different needs. Larger age gaps (2+ years) can strain the nanny.
• One family leaving: The most disruptive event. Require 4–8 weeks' notice and a plan for finding a replacement family or transitioning to solo care.
