How to Set Up a Nanny Share
What a nanny share actually is and how it works
A nanny share is an arrangement where two or more families hire one nanny together and split the cost, usually splitting the nanny's salary and payroll taxes roughly in half. The nanny works in one home (often rotating between the two) or sometimes in a neutral space like a community center, and watches all the children at once. The families divide expenses: the nanny's weekly pay, payroll taxes, benefits if offered, and sometimes supplies or activities.
The appeal is financial — you pay roughly half what a solo nanny costs — but it also means your child has a peer present during the day, and the nanny has built-in backup if she gets sick. The main trade-off is that you lose some control over scheduling and routines, and you need to find another family whose needs align closely with yours.
Key Takeaways
- A nanny share cuts your childcare costs roughly in half by splitting one nanny's salary between two families, but requires finding a compatible family and managing a three-way relationship.
- You will need a written agreement that covers pay, hours, sick days, whose home is used, what happens if one family leaves, and how decisions get made.
- Both families are responsible for payroll taxes and workers' compensation insurance, which you can handle through a payroll service or a household employment agency.
- Finding a nanny share partner often works best through word-of-mouth in your community, parent groups, or nanny-matching services that filter by location and schedule.
Finding another family to share with
The hardest part of setting up a nanny share is finding the right partner family. Your schedules need to overlap significantly, your children's ages should be compatible (a newborn and a five-year-old have very different needs), and you need to trust the other parents' values around discipline, screen time, and safety.
Start with people you already know: other parents at your child's current daycare, preschool, or playgroup, or friends with young children. Word-of-mouth is slower but produces families you can vet through existing relationships. If you don't have a ready network, try parent Facebook groups in your neighborhood, Nextdoor, or nanny-matching services like Care.com, Bambino, or Sittercity — many let you filter by location and search specifically for nanny share arrangements. Some cities have nanny-matching nonprofits or family resource centers that maintain lists of families looking to share.
Once you find a potential partner, have a conversation about logistics before you commit: What hours do you each need? Do your kids get along? What's your approach to discipline, screen time, and food? Are you comfortable with the nanny working in your home, theirs, or alternating? This conversation often reveals incompatibilities early.
What to put in a written agreement
A written agreement protects both families and the nanny. You don't need a lawyer to draft one — many nanny-matching services provide templates, and organizations like the International Nanny Association have sample agreements online. At minimum, cover these points:
- Pay and schedule: Weekly salary, how it's split between families, start and end times, which days, and whether the nanny works for one family or both if one family takes time off.
- Sick days and time off: How many paid sick days the nanny gets, what happens if she's sick, what happens if a child is sick, and how vacation time works.
- Location: Whose home the nanny works in, or whether she rotates, and who pays for utilities or supplies used during work hours.
- If one family leaves: How much notice is required, whether the remaining family can continue with the nanny solo, and what happens to the nanny's pay during the transition.
- Decision-making: How the families will handle disagreements about the nanny's pay, schedule changes, or discipline approaches.
- Taxes and insurance: Who handles payroll, whether the nanny is a W-2 employee or 1099 contractor (almost always W-2), and who pays for workers' compensation insurance.
Both families and the nanny should sign and keep a copy. If circumstances change — one family needs different hours, or the nanny wants a raise — update the agreement in writing rather than just agreeing verbally.
Handling payroll and taxes
A nanny is a household employee, which means both families are responsible for withholding income tax, Social Security, and Medicare from her pay, and for paying employer taxes and workers' compensation insurance. This is a legal requirement, not optional.
You have two main routes: use a payroll service designed for household employers, or hire a household employment agency to handle it for you. A payroll service like Bambino, GTM Household Payroll, or Care.com's payroll option costs roughly $100 to $300 per year and handles tax withholding, filing, and payment. You and the other family each set up an account, enter the nanny's hours and pay, and the service calculates what each family owes and files the taxes. The nanny receives a W-2 at year-end.
A household employment agency takes a larger cut — usually 5 to 10 percent of the nanny's gross pay — but handles everything: they employ the nanny on your behalf, manage all payroll and taxes, and carry workers' compensation insurance. You pay the agency, and the agency pays the nanny. This is simpler if you're uncomfortable with payroll details, but it costs more.
Whichever route you choose, both families need to agree upfront on who sets it up and how you'll split the cost of the service or agency fee. Some families split it equally; others split it proportionally based on hours used.
Managing the day-to-day relationship
A nanny share involves three adults making decisions together, which requires clear communication and realistic expectations. Establish a routine for check-ins: many families do a weekly text or brief call to discuss how the week went, any issues with the children, and upcoming schedule changes. Some use a shared notebook or app like Brightwheel or Tadpoles where the nanny logs the children's day and both families can see it.
Agree in advance on how you'll handle common friction points: What if one family's child is sick but the other family still needs care? What if one family wants to change the nanny's pay or hours? What if the families disagree about discipline or activities? Having a process for these conversations — like a monthly family meeting or a rule that changes need agreement from both families — prevents resentment from building.
Be realistic about the nanny's workload. Watching two or three young children is harder than watching one, and the nanny may need to set boundaries around activities or outings. If you're asking her to do laundry, meal prep, or other tasks beyond childcare, that should be spelled out in the agreement and reflected in her pay.
When a nanny share doesn't work out
Sometimes a nanny share ends because one family's needs change — they move, return to the office, or decide they want a solo nanny. Sometimes it ends because the families clash or the nanny isn't the right fit. Having an exit plan in your agreement makes this less painful.
A typical notice period is two weeks to a month, which gives the other family time to find a replacement or adjust their childcare plan. If one family leaves, the remaining family can sometimes continue with the nanny solo, though the nanny's pay will likely increase since she's no longer splitting her time. Discuss this possibility upfront so no one is surprised.
If the nanny leaves, both families need to decide whether to find a replacement nanny share or pursue different childcare. This is a good moment to reassess whether a nanny share still makes sense for your situation.
Frequently Asked Questions
What if the two families' schedules don't overlap completely?
Some nanny shares work with partial overlap — for example, one family needs care Monday through Wednesday and the other needs Thursday through Friday, with Wednesday as the overlap day. The nanny works five days a week, and the families split her pay proportionally based on the hours each uses. This requires a clear agreement about how pay is divided and how the nanny's schedule works on overlap days.
Can I do a nanny share if my child has special needs?
Yes, but it requires finding a family whose child has compatible needs and a nanny trained to handle them. If your child needs speech therapy, occupational therapy, or behavioral support, discuss this openly with potential partner families and make sure the nanny has experience or training. You may need to pay the nanny more, and both families should agree to this upfront.
What if one family stops paying their share?
This is why a written agreement matters. The agreement should specify that both families are jointly responsible for the nanny's full pay — if one family doesn't pay, the other family is still obligated to pay the nanny in full. You can then pursue the other family for reimbursement separately. Some families add a clause that if one family falls behind, the arrangement ends and both families must find new childcare.
Do I need to carry liability insurance for a nanny share in my home?
Check your homeowners or renters insurance policy. Some policies cover household employees automatically; others require an endorsement. If the nanny works in your home, you should have coverage in case she or a child is injured. The household employment agency or payroll service can advise on what's needed.
How much should I expect to pay for a nanny share?
Nanny pay varies by region, the nanny's experience, and the number of children. In most areas, a nanny caring for two children costs less per family than a solo nanny but more than center-based care. Research local nanny rates in your area, then divide by two to estimate your share. Many families find a nanny share costs 40 to 60 percent of what they'd pay for a solo nanny.
