How to pay a nanny in Washington

Everything a Washington family has to do to pay a nanny, housekeeper or caregiver legally: the taxes, the registrations, the forms, and the deadlines. CareTab does the math and reminds you; you keep paying them the way you already do.

The short version

Step by step

  1. Get an EIN from the IRS (free, online, 10 minutes).
  2. Have your nanny complete Form I-9 and, if they want federal income tax withheld, a W-4.
  3. File the Washington new-hire report within 20 days at the state site.
  4. Register with Washington Employment Security Department once you cross $1,000 or more in cash wages for domestic service in a calendar quarter (rcw 50.04.160) (registration).
  5. Each payday: track hours, pay at least minimum wage and overtime, withhold 7.65% plus state program premiums, give a pay stub.
  6. Each quarter: file Quarterly tax and wage report (EAMS). Last day of the month after each quarter. New-employer rate is the average rate for your industry, set by ESD on the rate notice mailed in December; enter it from your notice.
  7. January: W-2 to your nanny, W-2/W-3 to the SSA. April: Schedule H with your 1040.

Frequently asked

Do I have to pay nanny taxes in Washington?

Yes. Once you pay a household employee $3,000.00 or more in a year you owe Social Security and Medicare (7.65% withheld from your nanny and 7.65% from you), and FUTA once you pay $1,000.00 in any quarter. Washington unemployment tax applies after $1,000 or more in cash wages for domestic service in a calendar quarter (rcw 50.04.160).

Do I withhold Washington income tax from my nanny?

Washington has no state income tax, so there is nothing to withhold.

What forms do I file in Washington?

Quarterly tax and wage report (EAMS) quarterly with Washington Employment Security Department, a W-2 for your nanny and W-3 to the SSA by Jan 31, and Schedule H with your federal return.

Does my nanny get overtime in Washington?

Live-out nannies get 1.5× over 40 hours a week. Live-in nannies are exempt from overtime in Washington. Through June 30, 2027 the Minimum Wage Act excludes workers whose duties require them to reside or sleep at the place of employment (RCW 49.46.010(4)(j)); HB 2355 (2026 c 15) ends that exclusion for domestic workers on July 1, 2027. Bolina v. AssureCare (Wash. Jul. 9, 2026) struck the exclusion only as applied to adult family home caregivers. Seattle's Domestic Workers Ordinance has its own rules.

What is the minimum wage for a nanny in Washington?

$17.13 per hour in 2026 (schedule: $16.66 from 2025-01-01, $17.13 from 2026-01-01).
