What It Costs to Bring Your Nanny on Vacation

The week nobody budgets for

Bringing your nanny on a family trip is not an extension of a normal week. At home she works a bounded schedule, usually 45 to 50 hours, and the boundary is the front door. On a trip there is no front door. She is in the same house, the same hotel suite or the same rental as the children, and the hours she is expected to be available stretch from the first wake-up to the last bedtime handover.

Families routinely describe that as roughly 12 to 14 duty hours a day. That is not an aggressive estimate. It is what a 7am start and an 8pm finish looks like once you count breakfast, transit, the pool, the afternoon nap shift, dinner and bedtime. Seven of those days lands between 84 and 98 hours in a single workweek.

The Fair Labor Standards Act counts overtime by the workweek, not the day and not the month. Everything past 40 hours in that week is owed at one and a half times her regular rate. So a trip does not cost you one week of pay. It costs you closer to two.

What this page establishes

• A 7-day trip at 13 duty hours is 91 hours, of which 51 are overtime. At a $25 base rate that is about $2,913 in wages and roughly $223 in employer FICA.
• A flat day rate does not cap the bill. Under the day-rate rule it becomes the numerator of a regular-rate calculation and you still owe extra half-time on every hour past 40.
• Sleep time is rarely deductible for a live-out nanny travelling with you, and the narrow exclusion that does exist comes with conditions most trips fail.
• Flights, lodging and meals sit on top of all of it, and how you pay for them decides whether they are expenses or taxable wages.

How a week away turns into 90-plus hours

Start with the hours before you touch money. The table assumes a single workweek so the whole trip falls under one 40-hour threshold, which is the common case for a Sunday to Saturday departure. If your trip straddles two workweeks the totals are the same but the overtime is smaller, because each week gets its own 40 hours of straight time.

Duty hours below are an illustration of a typical family trip schedule, not a survey finding. Count your own itinerary hour by hour before you agree a rate.

Read the last column again. On a 13-hour trip schedule, 56 percent of the hours are premium hours. That is the structural fact that makes travel expensive, and it is why a rate that feels generous at home can still leave you badly short on a trip.

The wage bill at each base rate

Now put money on it. The table below holds the trip constant at seven days of 13 duty hours, 91 hours in one workweek, and varies only the base hourly rate. Employer FICA is the 7.65 percent employer share of Social Security and Medicare, which applies to the overtime premium exactly as it applies to straight time. There is no wage type here that escapes it.

None of those totals include a flight, a bed, a meal or a single dollar of the trip itself. On a domestic trip, adding a coach seat and a modest second room realistically puts another $900 to $2,500 on the bill. On an international trip it is considerably more. The honest way to think about a week away with your nanny is that the childcare line alone runs somewhere between $3,500 and $7,000, and the wage half of that is the half you cannot negotiate away.

One 2026 wrinkle worth knowing, because your nanny will ask. The federal deduction for qualified overtime compensation lets an employee deduct the premium half of FLSA overtime from taxable income, within limits, and from 2026 employers report that amount separately on Form W-2. It changes what she owes at filing time. It does not reduce your employer FICA and it does not reduce the gross you owe her, so nothing in the table above moves. It also applies only to overtime the FLSA itself requires, which matters for the state rules below.

Travel days are working days

The airport question comes up on every trip, and it has a cleaner answer than most families expect. There are two separate rules and people keep collapsing them into one.

The first rule is that any work actually performed while travelling is hours worked, full stop. A nanny who is holding a toddler through security, managing the snack bag on the plane, handling the car seat in the rental lot and doing the bedtime routine in a strange hotel is not a passenger. She is working, and the whole stretch counts. This is the situation on the overwhelming majority of family trips, because the reason she is on the plane is that you want help on the plane.

The second rule covers genuine passive travel away from the home community, where the employee has no duties at all. That time is work time when it cuts across her normal working hours, including the corresponding hours on a day she does not usually work. If her normal schedule is 8am to 6pm on weekdays, a Saturday flight that departs at 9am still eats into paid hours. The Department of Labor's enforcement policy carves out passive passenger time outside normal working hours, which is the only real narrowing here, and it evaporates the moment she picks up a child.

The practical answer: on a travel day, pay door to door unless she is genuinely released and knows it. If you plan to release her, say the hours out loud and put them in writing before you leave, because reconstructing them afterwards never goes well. If she drives her own car to the airport or drives yours on the trip, the mileage question is separate from the hours question and worth handling properly. See nanny mileage reimbursement for how that side works.

The sleep time question

This is where the biggest money is, and where the most confident bad advice lives. The short version: for a live-out nanny on a one-week trip, you generally cannot subtract the overnight hours.

For an employee on duty for less than 24 hours, time is hours worked even if she is permitted to sleep or do other things when nothing is happening, as long as she is required to be on duty. A nanny in the adjoining room, on the monitor, expected to respond to a wake-up, is on duty. Sleeping does not change that.

There is a narrow exclusion for an employee on duty for 24 hours or more. Up to eight hours of sleep may be excluded from hours worked, but only if three conditions hold at once: there is an express or implied agreement to exclude it, you furnish adequate sleeping facilities, and she can usually get an uninterrupted night's sleep. Department of Labor guidance treats "usually uninterrupted" as at least five consecutive hours, and if a night is broken up so badly that she does not get five, the entire sleep period counts as hours worked that night. A trip with a teething baby or a jet-lagged three-year-old fails that test on most nights, which is exactly when families most want to claim the deduction.

The other route people reach for is the live-in exemption. Under the FLSA, a domestic service employee who resides in the household is exempt from overtime, though never from minimum wage for all hours worked, and a live-in may exclude sleep time, meal time and other periods of complete freedom by agreement. Residence means living there permanently, or for extended periods, which regulators describe as working and sleeping on the premises five days a week totalling 120 hours or more, or five consecutive days or nights.

Two further points. Companionship services, the other well-known domestic exemption, is defined around care for someone elderly or with an illness, injury or disability, so it has never been a route out of overtime for ordinary childcare. And the federal live-in exemption is overridden in several states: California, New York, Hawaii, Massachusetts, Oregon and Maryland all require overtime for live-in domestic workers, with thresholds that vary from 40 to 45 hours a week. If any of those states is in play, the federal exemption is not the end of the analysis.

Why the flat day rate is the classic mistake

The instinct is understandable. Hours on a trip are hard to bound, so families reach for a clean number: $400 a day, all in, everyone knows where they stand. It is the single most common way families create an overtime liability without meaning to.

Household employees are non-exempt. The white-collar exemptions are built around duties a nanny does not perform, so there is no such thing as a salaried exempt nanny who can be worked unlimited hours for a fixed sum. You are allowed to pay a day rate. You are not allowed to use it to buy your way out of the overtime premium.

Under the FLSA's day-rate rule, if an employee is paid a flat sum for a day's work regardless of hours, her regular rate is the total of those day rates for the week divided by the hours actually worked, and she is then owed an extra half-time at that rate for every hour past 40. The day rate becomes the input to the calculation, not a substitute for it. Here is what that does to a seven-day, 91-hour trip.

The gap runs from about $690 to nearly $1,000 on a single week, and it grows with the day rate rather than shrinking. Note that a promised trip bonus behaves the same way: a non-discretionary bonus goes into the regular rate, which raises the overtime rate, which raises the total. If you want the certainty of a fixed number, the way to get it is to fix the hours, agree an hourly rate, and compute the overtime openly. Then the number is knowable in advance and it is also correct.

States with daily overtime change the shape

Federal overtime is weekly. Some states add a daily trigger, and when they do, the length of each day starts to matter as much as the length of the trip. California is the case that comes up most. Under its Domestic Worker Bill of Rights, a personal attendant, which is how a nanny is usually classified when housekeeping duties stay incidental, earns time-and-a-half after nine hours in a day or 45 hours in a week.

You do not pick one rule. You run both calculations and pay whichever produces the larger amount. The counter-intuitive result is that on a long trip the federal 40-hour rule usually wins, because California hands you five more straight-time hours a week before weekly overtime starts. California's daily rule bites hardest on short trips with very long days, which is precisely the long-weekend pattern most families actually book.

If the personal attendant classification does not hold, because more than an incidental share of her time goes to household work rather than caring for the children, California's general rules apply instead: overtime after eight hours a day, double time after twelve, and premium treatment for the seventh consecutive day in a workweek. On a seven-day trip with 13-hour days, all three of those triggers fire, and the total moves above the federal figure rather than below it. This is not a detail to guess at.

Which state's law applies when you travel is genuinely unsettled and depends on where the work is performed, where the employment relationship is based, and the specific statutes involved. We are not going to pretend there is a clean national answer. The conservative approach, and the one a payroll service will usually steer you to, is to apply whichever of the home-state and destination-state rules is more protective, and to document the reasoning. It costs less than being wrong.

Per diem, meals and lodging: expense or wages

The trip costs are the easy part to pay and the easy part to get wrong on the W-2. The dividing line is whether the payment sits inside an accountable plan, which requires a business purpose, adequate substantiation, and return of anything unspent. Inside it, the money is an expense reimbursement and stays out of wages and out of the FICA base. Outside it, the money is pay.

General treatment only. Per diem limits are set by federal rates that vary by city and change annually, and household situations differ. Confirm with a tax professional.

The simplest safe pattern for most families is to book and pay her travel and lodging directly, feed her with the family or reimburse meal receipts, and pay wages separately through normal payroll. That keeps two categories of money in two clearly separate buckets. The pattern that causes trouble is handing over an undocumented lump sum described as "for the trip," which is difficult to characterise as anything other than wages after the fact, and which may also have raised her overtime rate.

Agree this in writing before you book

Almost every travel dispute between a family and a nanny comes from the same source: the hours were never defined, so afterwards each side reconstructs them in good faith and arrives at a different number. Ten lines settled before the flights are booked prevents nearly all of it.

Then track the hours on the trip itself, day by day, in whatever your payroll system uses. A week of travel produces the single largest paycheck of the year for most nannies, and it is the one most likely to be looked at closely later. Getting the record right at the time costs nothing. Reconstructing it from memory in six months costs a great deal.

Deciding whether to bring her at all

Once the number is on the table, the decision gets easier rather than harder. Roughly $3,000 to $4,500 of wages and payroll tax for a week, plus travel and lodging, is a real amount of money, and it buys something real: continuity of care in an unfamiliar place and actual rest for the adults. Some families conclude it is the best money they spend all year. Others look at the same figure and decide a shorter trip, fewer duty hours, or local sitters at the destination fits better.

What none of them should do is agree to the trip without the arithmetic, then discover the size of the paycheck when it lands. If travel is a regular feature of your year, fold it into your annual planning alongside the other line items that sit on top of the hourly rate. Our guide to what nanny benefits actually cost covers the rest of that picture, and the nanny cost guide sets the baseline the trip is measured against.
