How to pay a nanny in Illinois

Everything a Illinois 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 and IL-W-4.
  3. File the Illinois new-hire report within 20 days at the state site.
  4. Register with Illinois Department of Employment Security (IDES) once you cross $1,000 or more in cash wages to household workers in any calendar quarter of the current or preceding calendar year (registration).
  5. Each payday: track hours, pay at least minimum wage and overtime, withhold 7.65%, give a pay stub.
  6. Each year: file UI-HA Report for Household Employers (annual) — or UI-3/40 quarterly. Household employers may file and pay annually on Form UI-HA by April 15 of the following year (otherwise quarterly UI-3/40 reports are due the last day of the month after each quarter). Register with Form REG-UI-1 through MyTax Illinois. 2026 new-employer (standard) rate 3.350% including the 0.550% fund builder, on the first $14,250 per employee; use the rate on your IDES Notice of Contribution Rate.
  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 Illinois?

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. Illinois unemployment tax applies after $1,000 or more in cash wages to household workers in any calendar quarter of the current or preceding calendar year.

Do I withhold Illinois income tax from my nanny?

Illinois does not require household employers to withhold state income tax; you can withhold voluntarily using IL-W-4 if your nanny asks.

What forms do I file in Illinois?

UI-HA Report for Household Employers (annual) — or UI-3/40 quarterly annual with Illinois Department of Employment Security (IDES), 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 Illinois?

Live-out nannies get 1.5× over 40 hours a week. Live-in nannies are also owed overtime in Illinois. Since the Domestic Workers' Bill of Rights (2017), the Illinois Minimum Wage Law covers domestic workers regardless of employer size (820 ILCS 105/3(d)) and requires time-and-a-half after 40 hours; the state overtime exemptions in 105/4a(2) do not include live-in domestic workers, so Illinois live-in workers are treated as owed overtime (the federal live-in exemption does not relieve the state obligation). Chicago and Cook County set higher local minimum wages.

What is the minimum wage for a nanny in Illinois?

$15.00 per hour in 2026.
