Paying a nanny on a 1099 is almost always the wrong call. The IRS classifies household workers like nannies as employees, not independent contractors, which means you owe employment taxes and must issue a Form W-2, not a 1099, at year’s end. For 2026, those obligations kick in once you pay a single household employee $3,000 or more in cash wages during the calendar year.1Internal Revenue Service. Topic No. 756, Employment Taxes for Household Employees Handing your nanny a 1099 at the end of the year doesn’t change any of that. It just sets up back taxes, penalties, and interest when the IRS or your state catches up.
Why the IRS Treats a Nanny as an Employee
The IRS applies a common-law test with three factors: behavioral control, financial control, and the type of relationship. In a typical nanny arrangement, all three point to employment.
Behavioral control usually settles it. If you decide when the nanny arrives, what the daily routine looks like, how meals are prepared, and when the children nap, you’re directing the work. That’s the hallmark of an employer-employee relationship. An independent contractor controls when, where, and how they deliver a service.
Financial control reinforces the picture. A nanny paid a flat hourly or weekly rate, using your food and supplies, with no real chance of financial profit or loss on the job, is economically dependent on you. Independent contractors invest in their own equipment, market to multiple clients, and carry the risk of each engagement.
The nature of the relationship matters too. Ongoing work, benefits like paid time off or sick days, and the basic expectation that the nanny will keep working for you indefinitely all signal employment rather than a defined project with an end date.
The practical result: attempting to treat a household nanny as an independent contractor is almost never defensible. You’ll need to issue a W-2 and handle employment taxes.2Internal Revenue Service. Publication 926, Household Employer’s Tax Guide
What Misclassifying a Nanny as a 1099 Contractor Costs
Issuing a 1099 to a nanny who should have been on payroll creates a cascade. The IRS can assess the employer’s full share of FICA and FUTA, plus the employee’s share you should have withheld. You’re on the hook for both halves.
Penalties stack on top of the unpaid taxes. Late deposit penalties range from 2% to 15% of the underpaid amount, depending on how late the payment is.3Internal Revenue Service. Failure to Deposit Penalty Failure to file correct information returns, meaning the W-2 you never issued, carries separate per-form penalties of $60 to $680 depending on when you correct the problem, with the highest tier applying when you intentionally disregard the filing requirement.4Internal Revenue Service. Information Return Penalties Interest accrues daily on all unpaid balances.
State exposure adds to the damage. If a misclassified nanny files an unemployment claim, your state labor department will investigate, reclassify the worker, and bill you for back unemployment contributions plus penalties. State audits can also flag minimum wage and overtime violations, each carrying its own fines.
The most common way families discover the mistake is when the nanny leaves and files for unemployment. By that point, you’re looking at multiple years of back taxes, compounding interest, and penalties from both the IRS and the state.
What You Owe Instead: Paying a Nanny on a W-2
Doing this correctly means treating yourself as a household employer. That involves an Employer Identification Number, ongoing payroll tax obligations, and a specific set of year-end filings.
Get an EIN Before the First Day
An EIN functions as your identifier for employer tax purposes. You can apply on the IRS website and receive one immediately at no cost.5Internal Revenue Service. Get an Employer Identification Number It goes on every tax form tied to your nanny’s employment.
Social Security and Medicare (FICA)
The combined FICA rate is 15.3% of your nanny’s gross wages, split evenly between you and your employee. You withhold 7.65% from each paycheck (6.2% for Social Security and 1.45% for Medicare) and pay a matching 7.65% from your own funds.1Internal Revenue Service. Topic No. 756, Employment Taxes for Household Employees You can choose to cover your nanny’s share instead of withholding it, but any amount you absorb counts as additional taxable wages on the W-2.
Federal Unemployment Tax (FUTA)
A separate FUTA obligation kicks in if you pay total cash wages of $1,000 or more in any calendar quarter of 2026. The gross rate is 6.0% on the first $7,000 of wages per employee, but a credit of up to 5.4% for state unemployment contributions typically reduces the effective rate to 0.6%.2Internal Revenue Service. Publication 926, Household Employer’s Tax Guide That works out to a maximum of $42 per employee per year. FUTA is entirely your responsibility and never comes out of your nanny’s pay.
Federal Income Tax Withholding Is Optional
You’re not required to withhold federal income tax from a household employee. But if your nanny asks you to, you should. Have them complete a Form W-4 and calculate withholding accordingly. Skipping it can leave your nanny with a surprise tax bill in April.
Schedule H and Estimated Payments
Household employers don’t file quarterly payroll returns the way businesses do. You settle up once a year on Schedule H, attached to your Form 1040. The total from Schedule H flows to Schedule 2 (Form 1040), line 9, and increases your overall tax liability or reduces your refund.6Internal Revenue Service. Schedule 2 (Form 1040) The deadline matches your personal return, typically April 15.7Internal Revenue Service. About Schedule H (Form 1040), Household Employment Taxes
To avoid an underpayment penalty, you can make estimated payments using Form 1040-ES. The 2026 quarterly due dates are April 15, June 15, September 15, and January 15, 2027.8Internal Revenue Service. 2026 Form 1040-ES, Estimated Tax for Individuals Another option is increasing withholding from your own paycheck to cover nanny taxes, which is often simpler than mailing quarterly vouchers.
Form W-2 and W-3 at Year-End
You prepare a Form W-2 showing your nanny’s total wages and everything withheld for FICA and income taxes. Your nanny’s copy is due by the January 31 statutory deadline. For the 2026 tax year, January 31, 2027 falls on a Sunday, so the deadline shifts to February 1, 2027.9Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) Copy A of the W-2, along with Form W-3 as the transmittal summary, goes to the Social Security Administration by the same date.10Social Security Administration. Deadline Dates to File W-2s
Tax Breaks You Forfeit by Paying on a 1099
Paying your nanny properly isn’t just a compliance question. It unlocks federal tax benefits that families paying off the books, or misusing a 1099, lose entirely. Both benefits require you to report the caregiver’s name, address, and Social Security number on Form 2441, so they’re effectively unavailable to anyone hiding the employment relationship.
Dependent Care FSA
If your employer offers a Dependent Care Flexible Spending Account, you can set aside pre-tax dollars to pay a nanny for the care of children under 13 while you work. For 2026, the annual contribution limit is $7,500 for single filers and married couples filing jointly, and $3,750 for married individuals filing separately. This is the first increase to the DCFSA cap in 40 years, up from the previous $5,000 limit. Because contributions are excluded from income, Social Security, and Medicare taxes, the actual savings at a combined marginal rate of 30% or more can exceed $2,000 per year. Your nanny’s wages and your share of the employment taxes both count as qualifying expenses.11Internal Revenue Service. Publication 503, Child and Dependent Care Expenses
Child and Dependent Care Tax Credit
If you don’t have access to a DCFSA, or your nanny costs exceed what the FSA covers, the Child and Dependent Care Tax Credit provides additional relief. You can claim it on up to $3,000 of qualifying expenses for one child, or $6,000 for two or more children.12Internal Revenue Service. Topic No. 602, Child and Dependent Care Credit The credit percentage runs from 20% to 35% depending on your adjusted gross income. You can use both the FSA and the credit in the same year, but expenses claimed for the credit must be reduced by any amount already covered through the FSA.
Nanny Shares Don’t Change the Answer
When two families share a nanny, both families are separate household employers, even if the care happens in only one home. Each family controls how the nanny performs the work and pays a portion of the wages, which creates two independent employer-employee relationships. Neither family gets to use a 1099.
In practice, each family must independently:
- Obtain its own EIN from the IRS
- Register as an employer with the state
- Run a separate payroll, withholding and remitting FICA on the wages that family pays
- Pay FUTA and state unemployment on its share of wages
- Issue a separate W-2 at year-end
The nanny receives two paychecks each pay period and two W-2s at tax time. Each family files its own Schedule H and independently claims its share of wages for the DCFSA or the Child and Dependent Care Tax Credit. If the nanny later files for unemployment, both families are named as employers.
