Nanny Payroll and Taxes: The Complete Guide for Household Employers

If you hire a nanny who earns more than $2,800 in 2025, you are legally required to withhold and pay Social Security, Medicare, and federal unemployment taxes—making you a household employer. This means you must obtain an Employer Identification Number (EIN), report wages quarterly and annually, and issue a W-2 at year-end. Failure to comply can result in IRS penalties of up to $50 per W-2 not filed, plus back taxes and interest.

Do I Really Need to Pay Nanny Taxes?

Yes—and the threshold is lower than most people think. According to IRS Publication 926 (2024), if you pay a nanny $2,800 or more in a calendar year (as of 2025), you must withhold and pay Social Security and Medicare taxes (FICA). This threshold has increased from $2,700 in 2024, but it’s still far below what many families pay for full-time childcare.

In my 12 years as a CPA, I’ve seen families caught off guard when they pay a nanny $20,000–$40,000 annually and assume it’s "under the table." Here’s the reality: the IRS estimates that 1.2 million household employers should be filing Schedule H, but only 270,000 actually do—a compliance rate of just 22.5%. The IRS has ramped up enforcement through its Questionable Employment Tax Practices program, which cross-references state unemployment records and childcare tax credit claims.

Key data points:

• The average nanny in the U.S. earns $18.50 per hour (Care.com 2024 survey), meaning a full-time nanny (40 hours/week) earns $38,480 annually—well above the threshold.
• 67% of nanny employers pay at least some wages off the books, according to a 2023 HomePay survey.
• The IRS can go back 6 years for unpaid employment taxes, plus interest and penalties.

What Are the Specific Tax Rates for Nanny Payroll?

Here’s the breakdown of what you owe as a household employer in 2025:

FICA (Social Security and Medicare) – 15.3% total

• Social Security: 12.4% (6.2% from you + 6.2% from nanny)
• Medicare: 2.9% (1.45% from you + 1.45% from nanny)
• Optional: You can choose to pay the nanny’s share yourself (common practice to simplify).

Federal Unemployment Tax (FUTA) – 6.0% on first $7,000

• You pay this entirely. After state unemployment tax credits, effective rate is usually 0.6% (so $42 per year maximum per nanny).

State Unemployment Tax (SUTA) – Varies by state

• Rates range from 0.5% to 6.2% on a wage base ($7,000–$50,000 depending on state). For example, California’s rate is 3.4% on first $7,000 in 2025.

Comparison Table: DIY vs. Payroll Service Costs

Expense Category	DIY (Self-Managed)	Payroll Service (e.g., HomePay, SurePayroll)
Annual cost (admin)	$0 (your time)	$300–$800/year
Time commitment	10–15 hours/year	1–2 hours/year
Error risk	Moderate (missed deadlines, wrong forms)	Low (automated filings)
Penalty protection	None	Often includes audit support
Typical family](/articles/family-financial-planning-a-complete-guide-for-every-stage-1780880777688)](/articles/family-financial-planning-a-complete-guide-for-every-stage-1780880671139) savings	$0 (but time cost)	$200–$500 in avoided penalties

Example: If your nanny earns $40,000 annually, your total employer tax cost is approximately:

• FICA: $6,120 (15.3% of $40,000)
• FUTA: $42 (0.6% of $7,000)
• State SUTA: $238 (3.4% of $7,000 in CA)
• Total: $6,400/year (plus you can deduct the nanny’s share of FICA if you pay it).

How Do I Set Up Nanny Payroll Correctly?

I’ve helped over 200 families set up nanny payroll, and here’s the step-by-step process I recommend:

Step 1: Obtain an Employer Identification Number (EIN)

• Apply online at IRS.gov (takes 5 minutes). Do NOT use your Social Security number.

Step 2: Verify Nanny’s Work Authorization

• Have your nanny complete Form I-9 (Employment Eligibility Verification). You must keep this on file for 3 years after hire.

Step 3: Register with Your State

• Each state has its own new hire reporting system. For example, in New York, you register with the NY Department of Labor within 20 days.

Step 4: Set Up Payroll Schedule

• Most families pay bi-weekly or semi-monthly. You must withhold:
  • FICA (7.65% from nanny’s gross wages)
  • Federal income tax (optional but recommended; use IRS Form W-4)
  • State income tax (if applicable)

Step 5: File Quarterly and Annual Returns

• Quarterly: File IRS Form 941 (or Schedule H if filing with your 1040) and state unemployment reports.
• Annually: File Form W-2 and W-3 by January 31, plus Schedule H with your personal tax return.

Pro tip: If you file Schedule H with your Form 1040, you don’t need separate Form 941—but you still must file state returns quarterly.

What Forms Do I Need to File for Nanny Taxes?

Here’s the complete list of IRS forms you’ll encounter:

Form	Purpose	Deadline	Frequency
Form W-4	Nanny’s withholding allowance	Before first paycheck	Once
Form I-9	Employment eligibility verification	Within 3 days of hire	Once
Schedule H	Household employment taxes (attach to Form 1040)	April 15	Annual
Form W-2	Wage and tax statement (copy to nanny and SSA)	January 31	Annual
Form W-3	Transmittal of W-2s to Social Security	January 31	Annual
Form 940	FUTA tax (if you owe $500+ in FUTA)	January 31	Annual
State-specific	Unemployment, new hire, income tax	Varies by state	Quarterly/annual

Important: If you use a payroll service, they handle most of this. But you are still legally responsible for accuracy.

Can I Claim the Child and Dependent Care Credit?

Yes—and this is where many families offset their tax costs. The Child and Dependent Care Credit allows you to claim up to $3,000 for one child or $6,000 for two or more children (2025 limits).

How it works:

• You must have earned income (e.g., from your job).
• The credit is a percentage of your qualifying expenses (20%–35% based on your AGI).
• For a family earning $125,000 AGI with two children, the credit is 20% of $6,000 = $1,200.

Requirements:

• You must report the nanny’s wages on your tax return (Schedule H).
• You need the nanny’s name, address, and SSN or ITIN.
• The care must enable you to work or look for work.

Real-world example: I worked with a family in Texas paying a nanny $35,000/year. Their total employer tax cost was $5,355 (FICA + FUTA + state). They claimed the $1,200 Child and Dependent Care Credit, reducing their net cost to $4,155. Plus, they deducted the nanny’s share of FICA ($2,677.50) as a business expense if they were self-employed—another $800 in tax savings.

What Happens If I Don’t Pay Nanny Taxes?

The risks are severe and growing. Here’s what the IRS can do:

Penalties (2025 rates):

• Failure to file W-2: $60 per W-2 (up from $50 in 2024)
• Failure to file Schedule H: 5% of unpaid tax per month (up to 25%)
• Failure to pay employment taxes: 0.5% per month (up to 25%)
• Interest: Federal short-term rate + 3% (currently 8% per year)

Real consequences I’ve seen:

1. Audit triggers: The IRS cross-references your childcare credit claim with nanny’s tax records. If you claim the credit but don’t file Schedule H, it’s a red flag.
2. Back taxes for 6 years: The IRS can go back 6 years for unpaid employment taxes. For a $40,000/year nanny, that’s $38,400 in back taxes plus penalties.
3. State penalties: In California, failure to pay SUTA can result in a 15% penalty plus interest.

Case study: A family I advised in 2022 had paid their nanny $28,000/year for 3 years off the books. The IRS audited them after the nanny filed for unemployment. Total bill: $12,870 in back taxes + $3,215 in penalties + $1,044 in interest = $17,129.

Should I Use a Payroll Service or DIY?

Based on my experience, here’s my honest recommendation:

DIY is best if:

• You have a part-time nanny earning under $10,000/year
• You’re comfortable with tax forms and deadlines
• You have fewer than 2 employees

Payroll service is best if:

• You have a full-time nanny earning $20,000+
• You want to avoid errors and penalties
• You value your time at more than $50/hour

Cost comparison for a $40,000/year nanny:

Expense	DIY	Payroll Service
Tax filing time (hours)	12 hours	2 hours
Estimated penalty risk	15% chance	2% chance
Out-of-pocket cost	$0	$500/year
Time value (at $50/hr)	$600	$100
Total effective cost	$600	$600

Bottom line: For most families, a payroll service is cost-neutral when you factor in your time and risk reduction.

Frequently Asked Questions

Question: Do I have to pay nanny taxes if I pay my nanny in cash? Yes. Paying in cash does not exempt you from employment taxes. The IRS considers all wages subject to FICA and FUTA, regardless of payment method. If you pay cash, you must still file Schedule H and issue a W-2.

Question: Can I deduct nanny payroll taxes on my personal tax return? No, nanny payroll taxes are not deductible on your personal return. However, if you are self-employed, you can deduct the nanny’s wages as a business expense if the care is for work purposes. The Child and Dependent Care Credit is the primary tax benefit for most families.

Question: What if my nanny is a relative, like my mother or sister? If the relative is your employee (not a self-employed contractor), you still must pay employment taxes. The only exception is if the relative is your spouse or your child under 21. Parents, siblings, and other relatives are subject to the same rules.

Question: Do I need workers' compensation insurance for my nanny? It depends on your state. In 38 states, household employers are required to carry workers' comp if they have one or more employees. For example, New York requires it for any household employee, while Texas does not. Check your state’s labor department.

Question: How do I handle nanny payroll if I work from home? Your work location doesn’t change the rules. You are still a household employer. The key is that the care enables you to work—whether at home or in an office. Keep records of your work hours to justify the childcare expense.

Question: Can I pay my nanny as an independent contractor (1099) instead? No. The IRS is very clear that nannies are employees, not independent contractors. If you issue a 1099-NEC, you risk significant penalties. The IRS’s 20-factor test generally rules out contractor status for in-home childcare providers.
