Nanny Share: How It Works and How to Set One Up

A nanny share is two families (occasionally three) employing one nanny together, who cares for all the children at the same time, usually in one family’s home. Each family pays its part of the wage, so each pays less than it would for a private nanny, and the nanny usually earns more than in a single-family job. In most shares both families are employers, with the tax and payroll duties that come with that. To set one up, find a family whose schedule and parenting style match yours, agree on a host home and a pay split, and put the whole arrangement in writing before day one.

That last step decides whether a share works. Most of the problems are between the two families, not with the childcare.

How a nanny share works day to day

The usual shape:

• One host home. The children are dropped at one family’s house each morning. Some shares rotate the host week by week or month by month. Most club shares found a fixed host simpler, with the host’s extra wear and tear recognized somewhere in the deal.
• One nanny, one shared day. Naps, meals, walks and play happen together, on a schedule both families agreed to.
• Two payrolls. Each family pays the nanny for its own share of the hours, rather than one family paying and billing the other.
• Two sets of instructions, merged. Feeding, naps, screens, discipline and outings follow one agreed plan. Where the families differ, the agreement says whose rule applies.

Shares work best when the children are close in age, so their days look alike. Two babies under one, or two toddlers, run on similar rhythms. A newborn paired with a two-year-old can work, but the nanny is running two different days at once.

Nanny share vs. private nanny vs. daycare

Compare the shape before any number, as the daycare, nanny or family guide recommends.

	Nanny share	Private nanny	Daycare center
Cost shape	Split between families; less per family than a private nanny	One family pays the full wage	Per child, set by the center
Children per adult	Two families’ children	Your children only	Set by the room and state rules
Where	Host home (yours or theirs)	Your home	The center
Hours	Negotiated across two families	Set by you	Fixed opening hours
When the nanny is sick	Both families lose care	You lose care	The center covers
When your child is sick	Agreement decides	Nanny can usually still come	Child stays home
Employer duties	Both families, usually	You	None (you are a customer)

The trade in one line: a share brings a nanny’s cost closer to a center’s and keeps most of a nanny’s flexibility, but you give up some control to the other family.

What it costs, and how the split works

The split is easier to agree than the number. The usual patterns:

• Even split. Same hours, same number of children: each family pays half the agreed total.
• Split by hours. If one family needs care until 6 p.m. and the other until 4, the late family pays for the extra hours on its own.
• Split by children. A family bringing two children usually pays a larger share than a family bringing one.

What the nanny earns is the bigger question. A share asks more of a nanny than a single-family job, so the combined rate is usually higher than one family would pay a private nanny. GTM, a household payroll company, says on its nanny share taxes page (checked October 2026) that “each family typically pays two-thirds of a nanny’s normal rate.” Treat that as a starting point, not a quote: rates vary a great deal by city, by experience and by the number of children.

When comparing a share to a center, include the hidden extras on both sides:

• Daycare: closure days, late-pickup fees and registration fees.
• Nanny share: your share of the employer taxes, payroll service costs, any workers’ compensation insurance your state requires, and the cost of covering the days the nanny is out.

Who is the employer, and the taxes

This is the part people skip, and it is the part with legal consequences. What follows is general information, not tax advice.

Both families are usually employers. HomeWork Solutions, a household payroll firm, quotes household-employment lawyer Bob King on its nanny share payroll page: “In most cases, both families are the nanny’s employer.” Both families pay the nanny, and both direct how the work is done. GTM’s page describes the same setup: each family gets an employer identification number, runs payroll for its own portion, and gives the nanny a W-2, so the nanny gets two paychecks and two W-2s.

The IRS rules apply to each family’s portion. IRS Publication 926, the 2026 Household Employer’s Tax Guide, sets out the federal thresholds:

• Social Security and Medicare. If you pay one household employee $3,000 or more in cash wages in 2026, you withhold and pay these taxes: 15.3% of cash wages, split 7.65% employee and 7.65% employer.
• Federal unemployment (FUTA). This applies if you pay household employees a total of $1,000 or more in cash wages in any calendar quarter of 2025 or 2026.
• Forms. You file Schedule H with your federal return and give the employee a Form W-2.
• Records. Keep employment tax records for at least 4 years.

Publication 926 also says you and a regular household employee must each complete Form I-9, with the employee’s section done no later than the first day of work. It adds that you should check with your state about state unemployment tax, other state employment taxes and workers’ compensation.

Pay at least minimum wage, and track the hours. The U.S. Department of Labor’s fact sheet on domestic workers lists nannies as domestic service workers. It says workers in private homes “must be paid at least the federal minimum wage for all hours worked and overtime pay at time and a half the regular rate of pay for all hours worked over 40 in a workweek, unless they are subject to an exemption.” Your state’s minimum wage may be higher. How overtime is counted when one nanny works for two households is a real question with setup-specific answers. Ask a household payroll service or an accountant before you agree a weekly schedule of more than 40 hours.

There is a tax upside. Publication 926 says that if your household employee cares for a dependent under 13 so you can work, you may be able to claim the child and dependent care credit. You can include the employee’s wages and your share of the employment taxes you paid (details in IRS Publication 503).

Most share families hand this to a household payroll service. Whatever you choose, agree it in writing, so neither family is quietly paying the nanny in cash.

Finding the right family

The other family matters more than the nanny, because a good nanny will leave a share where the parents fight. Find families through your birth class, local parent groups, your pediatrician’s waiting room board, neighborhood email lists or the care platforms. Then meet as adults, without the children, and get through these before you talk about money:

1. What hours do you need, and how fixed are they?
2. How far apart are our homes, and who would host?
3. How old are the children, and how far apart are their nap and feeding schedules?
4. What’s your rule on a sick child: fever, cold, stomach bug?
5. How do you feel about screens, sweets and outings in the car?
6. How do you handle discipline, and what words do you use?
7. What do you do about holidays: whose dates, and who pays when one family is away?
8. Is anyone in your house unvaccinated, smoking, or keeping pets the children would be around?
9. How long do you expect to need care: six months, two years?
10. How do you want to hear about problems, and how often should the families check in?

If the answers to questions 1, 4 and 7 don’t match, stop there. Those are the three that end shares.

The two-family agreement

Write two documents: one between the families, and one between the families and the nanny (a nanny contract). The family agreement should cover:

• The host home: who hosts, whether it rotates, and what the host family gets for the extra wear and use, such as a lower share of supplies.
• The pay split: who pays what, how raises are decided, and whether both families use the same payroll service.
• Sick children: when a sick child stays home, and whether the healthy child still comes.
• Holidays and absences: paid holidays, who pays when one family travels, and what happens when the nanny is sick. Each family will need its own backup childcare plan.
• Supplies: who buys diapers, wipes, food and toys, and how costs are shared.
• The shared rules: naps, feeding, screens, discipline and outings, written once so the nanny is not left to referee.
• Emergencies: both families’ contacts, both pediatricians, allergies and medical consent. One emergency info sheet per child, posted in the host home.
• Leaving the share: how much notice one family gives, and what happens to the nanny’s job if one family leaves.

The last item is where shares fail. When one family leaves, the other is suddenly paying a private nanny’s wage or looking for a new family fast. Agree the notice period now, while everyone is getting along.

Setting up the host home

Two children need two safe sleep spaces. The American Academy of Pediatrics’ safe sleep guide calls for a firm, flat surface in a “crib, bassinet, portable crib or play yard” that meets Consumer Product Safety Commission standards, with soft objects and loose bedding kept out. In a share, that usually means the guest baby’s own sleep space at the host home. A plain play yard like the Graco On the Go Pack ‘n Play is the common answer. Every baby goes down on their back, for every nap.

Walks need a two-seat stroller, and the host family usually owns it. A side-by-side such as the Baby Jogger City Mini GT2 Double is one well-reviewed example. Measure your front door before you buy one. The AAP guide says a baby who falls asleep in a stroller should be moved “to a firm sleep surface on their back as soon as possible.” Make sure the nanny knows that’s the rule for both children.

Naps are the daily puzzle. Two children rarely nap at the same moment, especially months apart in age. A reference for how nap counts and wake times shift as babies grow helps both families agree on a realistic shared day rather than one child’s ideal day.

Signs a share is not working

Watch for these in the first two months:

• One family keeps arriving late or asking for extra hours the other is not paying for.
• The nanny is settling disagreements between the parents.
• One child’s needs fill the whole day. A share can survive a lot, but not a nanny who effectively has one child and a bystander.
• Pay or tax conversations keep getting put off.

Any one of these is fixable if raised early at the regular check-in. Several together usually mean it’s time to use the exit clause, kindly and on the notice you agreed.

FAQ: nanny shares

How much cheaper is a nanny share than a private nanny?

It depends on the split and your area. GTM, a payroll company, says each family “typically” pays about two-thirds of a nanny’s normal rate (checked October 2026), so the saving per family is real but smaller than half.

Do both families have to pay taxes in a nanny share?

Usually, yes. In most shares both families are employers. Each runs payroll for its own portion, and each owes the federal household employment taxes once its cash wages reach the IRS thresholds ($3,000 for Social Security and Medicare in 2026).

Whose house should host the nanny share?

Whichever home has the room, a safe sleep space for each child, and a commute that works for both families. A fixed host is simpler. A rotating host shares the wear but means packing up twice as often.

What age is best for a nanny share?

Shares are easiest when the children are within about a year of each other, so their naps and meals line up. Wider gaps can work if the nanny is experienced and the agreement accounts for two different days.

What happens if one family leaves the share?

Whatever your agreement says, which is why it needs a notice period. Without one, the remaining family is suddenly paying the full wage or searching for a new family on short notice.
