Nanny vs Babysitter: Which One Do You Actually Need?

	Babysitter	Nanny
When	Occasional. Evenings, weekends, when you need them.	A set schedule, most weeks.
Scope	Keep the children safe, fed and in bed.	Childcare plus the household work that belongs to the children.
Paid	Per hour, usually that night.	Salary or a regular weekly wage.
Typical age	Often a teenager or college student.	Almost always an adult, often career childcare.
Your tax position	Usually nothing to file.	You may be a household employer.

A useful test: if the person is fitting your evening around their own schedule, you are hiring a babysitter. If your schedule is their job, you are hiring a nanny.

What each one costs in 2026

Babysitters are paid hourly and the number moves with your city and the number of children. The 2026 national average is about $26 an hour for one child, ranging from roughly $18 in San Antonio to nearly $30 in San Francisco. Add $2 to $5 per additional child.

Nannies are quoted weekly. A full-time nanny in a mid-sized US city typically runs $700 to $1,000 a week, more in high-cost metros, and that is before employer taxes.

The tax part nobody mentions

This is the difference that costs people money, so it is worth being precise.

If you pay any one household worker more than the IRS threshold for the year (it was $2,800 in 2025 and is indexed upward), you may be a household employer. That can mean withholding and paying Social Security and Medicare, and filing Schedule H with your return. Most nannies cross that line. Most occasional babysitters do not.

There are exceptions that matter here: wages paid to someone under 18 are generally excluded unless childcare is their principal occupation, which is why paying a local teenager for Friday nights usually creates no filing obligation at all.

Which one you actually need

Hire a babysitter if

• You need someone occasionally, or on nights that change week to week.
• The job is essentially: keep everyone safe, handle dinner and bedtime.
• You want to pay per hour and be done.

Hire a nanny if

• You need the same hours every week and can commit to them.
• You want continuity — one adult who knows the routine, the allergies, the school run.
• You are prepared to be an employer, with the paperwork that implies.

There is a middle option people forget: a regular babysitter. The same person, every other Friday, paid hourly. You get most of the continuity of a nanny at a fraction of the cost and none of the tax complexity.

How to check either one is safe

This is where the two jobs converge, because the question is identical: can you verify anything this person told you?

• Training you can look up. Ask what they are certified in and ask to see it. A certificate with a page you can open and check is worth more than a claim.
• References you actually call. Two families, and ask each one the same question: would you leave them again tomorrow?
• The emergency question. Ask what they would do if a child stopped breathing. You want a sequence of steps, not a feeling. “I’d stay calm and call you” means nobody ever taught them.
• A background check, done properly. If you want one, it must be run through a consumer reporting agency, with the person’s written permission, and if you decide against them because of what it says you owe them a copy and a chance to dispute it. Those are Fair Credit Reporting Act requirements, not optional courtesies. Do not use a people-search site for this — it is not compliant and the data is often wrong.
