Babysitting Money and Taxes: Where the Line Sits

Babysitting money feels like the most informal cash in America: a few twenties handed over at the door, a regular Friday arrangement, a summer of watching the neighbor’s kids. But the tax code has opinions about that money, on both sides of the handoff. In some situations the parents are legally an employer, complete with payroll obligations. In others the sitter is running a small business and owes self-employment tax. Knowing where the line sits keeps a friendly arrangement from turning into an April surprise.

The good news is that the rules are more forgiving than people fear, especially for teenage sitters. Here is how the IRS actually draws the lines, with the numbers that apply in 2026.

The control test: whose employee is the sitter?

The IRS treats babysitters and nannies as potential household employees, alongside housekeepers and gardeners. The test, laid out in Tax Topic 756, is control: household workers are your employees if you can control not only the work they do but also how they do it. A nanny who comes to your home on your schedule and follows your instructions fits that description. By contrast, someone who runs a daycare out of her own home, sets her own rules and takes many families’ children is generally an independent operator, not your employee. The IRS’s page on hiring household employees walks through the distinction.

The $3,000 threshold for parents

Being an employer only triggers payroll taxes above a dollar line that resets each year. For 2026, if you pay cash wages of $3,000 or more to any one household employee during the year, you are generally required to withhold the employee’s share of Social Security and Medicare taxes, 7.65 percent of wages, and pay a matching 7.65 percent yourself. Below the threshold, those taxes do not apply. A separate rule covers federal unemployment tax: paying household employees more than $1,000 in cash wages in any calendar quarter generally obligates you to pay FUTA tax on the first $7,000 of each employee’s wages. Employers who cross these lines report and pay through Schedule H filed with their own tax return, and the full rulebook is Publication 926, the Household Employer’s Tax Guide.

Note what is not required: you generally do not have to withhold federal income tax from a household employee’s pay unless the employee asks and you agree.

The teenager exception that saves most families

Here is the rule that keeps the ordinary Friday-night sitter out of the payroll system entirely. Social Security and Medicare taxes do not apply to wages paid to an employee who is under 18 at any time during the year, unless household work is that person’s principal occupation, and the IRS says plainly that if the employee is a student, household work is not considered their principal occupation. In practical terms: the 16-year-old from down the street who babysits between classes is exempt from the nanny-tax machinery even if her earnings from your family pass the annual threshold. The same topic page lists other exempt categories, including wages paid to your spouse, your child under 21 and, with exceptions, your parent.

The sitter’s side: the $400 line

Whether or not anyone withholds anything, the money is taxable income to the sitter, and sitters who are not household employees are self-employed in the eyes of the IRS. The rule that matters most is the self-employment tax trigger: net earnings of $400 or more from self-employment in a year mean you must file a return and pay self-employment tax, which covers Social Security and Medicare, as described in the IRS Self-Employed Individuals Tax Center. That is true even for a student who owes no income tax because her total earnings are small; self-employment tax runs on its own track.

For an adult doing regular sitting or home daycare, treating it as the business it is has advantages too. Keeping records of income and expenses, supplies, mileage between jobs where deductible, allows legitimate deductions that shrink the taxable profit, and the reported earnings build the sitter’s own Social Security record, which is how work credits toward future retirement and disability benefits accumulate.

Getting an informal arrangement right

For most families and most teenage sitters, the honest summary is reassuring: occasional babysitting by a student under 18 creates no employer obligations for the parents, and the sitter owes taxes only once her net earnings pass the filing thresholds. The situations that demand attention are the bigger ones. A family paying a regular caregiver $3,000 or more this year should plan on Schedule H, getting an employer identification number and issuing a W-2. A caregiver clearing $400 in profit should plan on filing. And both sides should settle the question at hiring time, not at tax time, because the classification drives everything else. Ten minutes of clarity in June is far cheaper than an amended return in April.
