Most of nanny payroll works the same way year to year — the same forms, the same 15.3% FICA math, the same Schedule H at the end. But a few of the numbers reset every January, and 2026 brought a couple of changes worth knowing before you run your first pay period of the year.
1. The FICA wage threshold rose to $3,000
The dollar amount that triggers Social Security and Medicare taxes went up. For 2026 it's $3,000 in cash wages to a single household employee during the year, up from $2,800 in 2025. Cross that line and you owe FICA on the wages — and it applies to the full year's pay, not just the amount above the threshold.
2. The Social Security wage base went up
Social Security tax (the 6.2% half of FICA) only applies up to an annual wage base, which climbed to $184,500 for 2026 from $176,100 in 2025. For almost every nanny this is a non-issue — a household employee would have to earn more than $184,500 from you in a single year before the cap mattered. The Medicare portion (1.45%) has no wage cap.
3. The Dependent Care FSA limit jumped to $7,500
This is the big one for families. For the first time since the 1980s, the Dependent Care FSA limit increased — from $5,000 to $7,500 per household for 2026 ($3,750 if married filing separately). If your employer offers a Dependent Care FSA, you can now run up to $7,500 of your nanny's wages through it with pre-tax dollars, which can save a meaningful chunk on federal income and FICA taxes.
House is set to the current year's thresholds and rates, so your withholding and Schedule H figures use the right numbers automatically.
Run 2026 payroll freeWhat stayed the same
- FICA rate: still 15.3% total — 7.65% withheld from your nanny, 7.65% paid by you.
- FUTA: still 6% on the first $7,000 of wages, effectively 0.6% after the standard state credit.
- The forms: W-4 and I-9 at hire, pay stubs each period, W-2/W-3 at year-end, Schedule H with your 1040.
- Classification: a regular nanny is still a W-2 employee, not a 1099 contractor.
The bottom line
For 2026: a higher wage threshold ($3,000), a higher Social Security cap ($184,500), and a much larger Dependent Care FSA ($7,500). The mechanics of running payroll didn't change — just plug in the new numbers and keep going.
