Nanny Payroll Taxes: The 2026 Employer's Guide (Thresholds, Rates, and Deadlines)

Family Ledger · 2026-10-13 · 11 min read

Some money questions keep you up at night. Nanny taxes are one of them — because the moment you hire a nanny, the IRS quietly turns you into an employer, with employer paperwork and employer taxes. Most families don't find this out until someone mentions "nanny taxes" at a playgroup and their stomach drops.

Here's the full 2026 picture in plain English: what you owe, when you owe it, the forms involved, and the traps to avoid. (For what the nanny herself costs before taxes, see our nanny cost guide.)

Why You're an Employer Now (Like It or Not)

The IRS has a category called household employee: nannies, housekeepers, and caregivers who work in your home under your direction. If you set your nanny's schedule and provide the workplace (your house), she's your employee — and the "we'll just pay cash" plan doesn't work. Paying under the table risks back taxes, penalties, and interest, and it shortchanges your nanny's Social Security record. The legal path is also the decent one.

The $3,000 Threshold: When FICA Kicks In

FICA stands for the Federal Insurance Contributions Act — it's the formal name for Social Security and Medicare taxes. For 2026, the trigger is simple:

> Pay any single household employee $3,000 or more in cash wages during the year, and you owe FICA.

At real nanny rates, you'll cross $3,000 fast — about $58 a week gets you there over a full year. A full-time nanny blows past it by February.

Here's how the rate splits (2026):

Two fine-print items: Social Security tax stops applying above the $184,500 wage base for 2026 (irrelevant for most nannies, but it exists), while Medicare tax has no cap. And wages above $200,000 trigger an extra 0.9% Medicare tax — paid by the employee only.

Important: the $3,000 test applies to the full amount, not the amount above $3,000. One nanny paid $3,000 triggers FICA on the entire $3,000. (Two different babysitters paid $2,000 each trigger nothing — it's per employee.)

A Worked Example: What 7.65% Looks Like in Dollars

Say you pay your nanny $20/hour for 40 hours a week:

Your nanny's paycheck each week is $800 minus her $61.20 FICA withholding (plus any income tax withholding). Your cost is $800 plus your $61.20 employer share — $861.20 a week. That's the 7.65% most families forget to budget.

FUTA: The Unemployment Tax You Also Owe

There's a second federal tax: FUTA, the Federal Unemployment Tax Act, paid entirely by the employer.

• Trigger: $1,000 or more in total household wages in any calendar quarter — all your household employees combined (unlike FICA's per-employee test).
• Rate: 6% on the first $7,000 of each employee's wages, but a credit for state unemployment taxes drops the effective rate to 0.6% in most cases — about $42 per employee per year, reported on Schedule H.

Your Paperwork Calendar for 2026

Household employers get a simplified system — one annual filing instead of quarterly payroll returns:

1. Get an EIN (Employer Identification Number). Apply free through the IRS (online is fastest). You need this before you run payroll. 2. Each payday: withhold your nanny's 7.65% FICA from her check. You're not required to withhold federal income tax, but you can if she asks (Form W-4). 3. By January 31, 2027: give your nanny her W-2 and file copy A with the Social Security Administration (plus Form W-3). 4. By April 15, 2027: file Schedule H (Household Employment Taxes) with your personal Form 1040. This is where you report and pay your employer FICA, her withheld FICA, and FUTA — all in one place.

One caution: the taxes come due with your return in April rather than throughout the year, so set aside ~8% of each paycheck in a separate savings account — or let a payroll service handle estimated payments.

State Taxes and Workers' Comp: The Part That Varies

Federal rules are uniform; state rules are a patchwork:

• State unemployment insurance (SUTA). Thresholds are often lower than federal FUTA — California kicks in at $750 in a quarter, D.C. and New York at just $500. Register with your state's labor department when you hire.
• State income tax withholding. Some states require it for household employees; check yours.
• Workers' compensation insurance. Many states require a policy the moment you hire household help. If your nanny is injured in your home without coverage, you're exposed. Get the policy — it's usually a few hundred dollars a year.

Who's Exempt: The Exceptions That Actually Exist

• Your spouse and your child under 21 — paying your own teenager to watch a sibling is exempt from FICA.
• Your parent — generally exempt, with narrow exceptions.
• Workers under 18 — a teenage babysitter is exempt unless household work is their principal occupation.

None of these describe a typical adult nanny — which is exactly the point. If you hired a professional nanny, you're in the system.

Should You Use a Payroll Service?

You can DIY: get an EIN, run the math each payday, file the W-2, fill out Schedule H. Plenty of families do. But a household-employer payroll service — about $50–$75/month — calculates withholding, generates pay stubs, files the W-2, prepares your Schedule H figures, and reminds you about state registrations. For most first-time nanny families, it pays for itself in avoided anxiety alone. Get one before the first paycheck, not after the first tax season.

The Tax Break That Softens the Blow

• Dependent care FSA: for 2026, set aside up to $7,500 pre-tax (up from $5,000 in 2025). Nanny wages qualify. At a 22% bracket plus 7.65% FICA savings, maxing it out saves roughly $2,225 a year. It's use-it-or-lose-it.
• Child and Dependent Care Tax Credit: if you don't have an FSA, the federal credit can offset 20–50% of qualifying expenses up to $3,000 for one child. You can't double-dip the same dollars through both — pick the better deal.

FAQ

No. The IRS is explicit: if you control what work is done and how it's done — her schedule, her duties, your home — she's an employee, not an independent contractor. A 1099 doesn't make her one; it just documents the misclassification.

Then no FICA is owed for that worker — the threshold is per employee, per year. But track it honestly: at $20/hour, $3,000 is only 150 hours, about three hours a week. Most regular arrangements cross it.

No — FICA is per employee. But FUTA's $1,000-per-quarter trigger combines all household employees, so two part-timers can trigger FUTA without either triggering FICA.

File it late rather than never — penalties grow with delay, and the IRS penalizes missing W-2s separately from Schedule H. A payroll service or CPA can help you catch up.

No — the employer's 7.65% is legally yours and can't be shifted to her. (Some families "gross up" her pay to cover her share, but your share stays your share.) She can handle her own income tax through quarterly estimated payments if you don't withhold it.
