Overtime in a nanny share — who pays the extra

Overtime in a nanny share means the nanny’s total hours in the workweek can trigger time-and-a-half pay. Both families need a pre-agreed way to split those extra dollars on one statement so one household does not silently eat the premium.

Why overtime feels confusing with two payers

You have one nanny and two families writing checks. Federal overtime rules still look at one employee’s hours in a workweek (the standard seven-day period your payroll uses). You do not get a brand-new 40-hour allowance per family just because you split regular hours 50/50.

Hours over 40 in that workweek are paid at time-and-a-half the regular rate (Fact Sheet 23). Use one regular rate for the week — do not calculate a separate one in each family’s notebook.

NannySplit shows overtime lines from hours you log. Families still pay those wages through payroll.

A week that looks “fine” on each family’s calendar can still go long. Jones sees 22 shared hours plus 6 solo → 28 on their scrap paper. Williams sees the same 22 shared plus 8 solo → 30 on theirs. Those totals double-count the shared block; the nanny’s unique hours are still 22 + 6 + 8 = 36 when solo time does not overlap the shared shift. Add a late pickup and you are over 40 without either family feeling they “caused” overtime.

What counts toward the week

Domestic service hours generally include time on duty or on the premises when the caregiver cannot freely use the time for themselves (Fact Sheet 79D). Early arrival, handoff waiting, and travel between homes matter because those minutes can push totals over 40.

Agree on logging rules that match how you actually work, then stick to them. The cost-split guide explains shared vs solo hours; overtime sits on top of total logged time, not on each family’s guess.

Solo tags change who pays regular wages. They do not shrink the workweek. Mis-tagged solo hours still count toward 40.

Regular rate in plain language

For most hourly nannies, the regular rate starts as the hourly wage for the week, including certain premiums defined by law. Overtime pay uses one and one-half times that rate for hours over 40 in the workweek.

If the two families pay different base rates, decide whose rate (or what blend) feeds that weekly regular rate before the long week happens. Changing the method after Thursday is how one household feels ambushed.

Allocating overtime dollars between households

Federal sources define when overtime wages are owed and how to compute the employee’s premium. They do not prescribe how Host and Guest should divide that premium on a nanny-share spreadsheet.

Typical settlement patterns families choose:

• Split the OT premium the same way you split shared regular hours.
• Allocate OT in proportion to wages each household pays for the week.
• Assign specific OT blocks to the family that scheduled the extra time, only if you document that clearly.

Pick one approach before the long week happens. Put it in the same place you keep split percentages so NannySplit can show both households matching OT rows.

If Williams asked the nanny to cover a Saturday birthday and that Saturday pushed the week over 40, the third pattern puts Saturday’s premium on Williams. The first pattern still splits Saturday 50/50. Either is fine if you wrote it down in advance.

Live-in shares (only if this is you)

Live-in domestic workers follow different daily overtime rules than many non-live-in workers (Fact Sheet 79B). If your share is live-in, read that sheet. Do not assume every nanny share matches the live-in pattern.

Payroll, taxes, and the statement

When overtime is owed, wages including the premium still flow through each household’s payroll process. IRS Publication 926 describes household employer tax responsibilities on those wages.

Your statement answers a narrower question: for this approved period, how much OT cost lands on each family? The planning calculator can estimate a heavy week; it is not the in-app statement.

Before the next long week

Confirm how you log travel, waiting, and handoffs. Document your OT dollar split method alongside your shared-hour split. Walk through a sample week on paper or the calculator, then compare to a dry run in NannySplit.

If the nanny works a partial day at each home, note whether you tag those blocks as shared or solo before they stack into overtime. Mis-tagged solo hours do not shrink the workweek, but they do change how regular wages split before the premium appears.

For host-home scheduling quirks, see host vs guest family. Setup context lives in the nanny share guide on the guides hub. When your rules match reality, start a share below and close periods from the same hours both families already approved.

Illustrative OT split

Suppose the nanny works 44 hours in the workweek and the overtime premium for those four hours is $60 total (after payroll’s legal calculation). Families might agree:

• Even split of the premium: $30 each, regardless of which house the extra hours happened at.
• Proportional to regular wages: if Jones pays 55% of regular wages that week, they pay 55% of the $60 premium.

Write yours down, enter it in NannySplit, and review OT rows before approval.

State laws may add rules beyond this federal overview. This guide does not catalog states. Recheck when you hire in a new location or change live-in status.
