How the Nanny Paycheck Calculator Works

This calculator shows nannies their actual take-home pay after all taxes and shows families the true cost of employing a nanny legally. You enter hourly rate and weekly hours. The tool calculates gross pay, withholds federal tax, state tax, Social Security, and Medicare, then shows net pay. It also calculates employer payroll taxes.

The formula:

If you make $20/hour for 40 hours weekly, gross pay is $800. FICA takes $61.20, federal tax roughly $80-100 (varies by filing status), state tax $40 (at 5%). Net weekly take-home is about $600-620, or $2,400-2,480 monthly.

For the family, that $800 weekly wage costs about $925 after employer payroll taxes (FICA, FUTA, SUTA).

Understanding Nanny Pay and Household Employment

Nannies are household employees under IRS rules. This means families must follow employment tax laws: withhold income taxes and FICA, pay employer payroll taxes, and issue W-2s annually. There’s no legal way around this if you pay a nanny more than $2,700 per year (2024 threshold).

Why Nannies Aren’t Independent Contractors

Many families want to treat nannies as 1099 contractors to avoid payroll taxes and paperwork. This is illegal. The IRS uses a control test: if you set the nanny’s schedule, provide supplies, and direct their work, they’re an employee, not a contractor.

Misclassifying a nanny as a contractor creates serious problems. The IRS can audit, assess back taxes plus penalties for both parties, and the nanny loses Social Security credits toward future benefits.

What Gets Withheld From Nanny Paychecks

Federal income tax: Based on the nanny’s W-4 form and filing status. A single nanny making $40,000 annually might have $60-80 withheld weekly.

State income tax: Varies by state. Some states have no income tax (Florida, Texas, Nevada). Others range from 3-10%+. This calculator uses your input rate.

Social Security: 6.2% of gross wages up to the wage base ($168,600 for 2024). Both employee and employer pay this.

Medicare: 1.45% of all gross wages with no cap. Both employee and employer pay this.

Total FICA (Social Security plus Medicare) is 7.65% from the employee’s pay and 7.65% paid by the employer on top of wages.

What Employer Taxes Cost Families

Families don’t just pay the nanny’s wage. They also pay employer payroll taxes on top:

Employer FICA: 7.65% (matches the employee’s withholding). On $800 weekly wages, that’s $61.20 the family pays in addition to the $800.

FUTA (Federal Unemployment Tax): 6% on first $7,000 of annual wages, but usually reduced to 0.6% with state credits. About $42 annually per employee.

SUTA (State Unemployment Tax): Varies by state, typically 2-5% on wages. Some states have higher rates or different wage bases.

A $20/hour nanny working 40 hours weekly costs the family roughly $42,000 in gross wages plus $3,200 in employer taxes, totaling $45,200 annually.

Common Mistakes With Nanny Pay

Paying Cash Under the Table

This is illegal for both parties. The family evades employer taxes. The nanny doesn’t report income or pay into Social Security. If caught, both face penalties, back taxes, and interest.

The nanny loses Social Security credits needed for retirement benefits and disability coverage. Years of unreported income mean lower (or zero) Social Security benefits later.

Families can’t deduct childcare expenses or claim dependent care FSAs without proper tax documentation. You lose thousands in potential tax benefits by paying under the table.

Not Understanding Overtime Rules

Most nannies qualify for overtime pay under the Fair Labor Standards Act. Hours over 40 per week must be paid at 1.5 times the regular rate. Some states require overtime after 8 hours in a day.

Live-in nannies have different rules in some states. California, New York, and other states have specific domestic worker protections with stricter overtime requirements.

Example: A $20/hour nanny working 50 hours owes 40 hours at $20 ($800) plus 10 hours at $30 ($300), totaling $1,100 weekly, not $1,000.

Forgetting About Nanny Taxes When Budgeting

Families budget for the nanny’s take-home pay without accounting for employer taxes. If you can afford $800 weekly take-home for the nanny, you actually need to budget $1,100+ to cover gross wages plus employer payroll taxes.

A nanny making $50,000 annually costs the employer $53,000-54,000 after payroll taxes. Budget for total cost, not just the wage.

Not Providing a W-2

Families must issue W-2s by January 31 each year. Without a W-2, the nanny can’t file taxes or prove income for loans, apartments, or government benefits.

The IRS can penalize families $50-280 per form for late or missing W-2s, plus additional penalties for intentional disregard.

Misunderstanding Gross vs. Net Pay

Nannies see a $20/hour offer and think they’ll take home $800 weekly for 40 hours. They don’t. After taxes, it’s $600-650 depending on filing status and state.

Always calculate and discuss take-home pay during negotiations so both parties understand the real numbers.

Edge Cases and Real Scenarios

What If I’m a Nanny Share?

In a nanny share, two families split one nanny. Each family is a separate employer and must handle payroll separately for their portion of hours and wages.

Example: Family A pays $15/hour for 20 hours weekly. Family B pays $15/hour for 20 hours weekly. The nanny has two jobs, two W-2s, and each family processes payroll independently. The nanny’s total is $30/hour equivalent for 40 hours.

Both families must withhold taxes on their portion and pay employer taxes. The nanny might owe higher taxes because combined income pushes them into a higher bracket.

What If My Nanny Is Live-In?

Room and board can be credited toward minimum wage in some states, but rules vary widely. Federal law allows it, but states like California don’t. Check your state’s domestic worker laws.

The value of lodging must be reasonable and documented. If you provide $1,000/month in housing, you can’t claim $2,000 as credit. Use fair market value.

Live-in arrangements don’t eliminate overtime requirements. If a live-in nanny works 60 hours, they’re owed overtime for hours over 40 (or whatever your state requires).

What If I Pay Daily or Weekly Instead of Hourly?

The payment structure doesn’t change tax obligations. If you pay $1,000 weekly for any number of hours, convert it to hourly to check minimum wage and overtime compliance.

$1,000 for 50 hours is $20/hour. But overtime rules still apply. The first 40 hours are regular, the next 10 are overtime. To be compliant, that $1,000 should break down as $800 regular + $300 overtime (assuming a base rate).

What If My Nanny Works Irregular Hours?

Track hours carefully. Some weeks might be 30 hours, others 50. Pay based on actual hours worked. Overtime applies to weeks exceeding 40 hours, not averaged across pay periods.

You can’t average hours to avoid overtime. Working 30 hours one week and 50 the next doesn’t mean 40 average with no overtime. The 50-hour week requires 10 hours of overtime pay.

What If I Provide Benefits?

Paid time off, health insurance stipends, and other benefits don’t count toward wages for hourly rate calculations but may be taxable income.

Health insurance you pay is typically tax-free to the nanny if done correctly. Cash stipends for health insurance are taxable wages. Holiday bonuses are taxable wages subject to withholding.

What If My Nanny Has Another Job?

Combined income from multiple jobs affects their tax bracket. A nanny working 20 hours for you at $20/hour ($20,800 annually) plus 20 hours elsewhere at $18/hour ($18,720 annually) has $39,520 total income.

Withholding at each job assumes it’s their only job. They’ll likely owe taxes when filing. Advise them to adjust their W-4 or pay estimated taxes quarterly.

How to Handle Nanny Payroll Legally

Option 1: Use a Nanny Payroll Service

Services like HomePay, Poppins Payroll, or SurePayroll handle everything: calculate withholding, process paychecks, file quarterly taxes, issue W-2s. Cost is $30-60 monthly.

This is the easiest option for most families. You provide hours and wage, they handle compliance.

Option 2: DIY Payroll

Calculate withholding using IRS tax tables, track hours, write paychecks, file quarterly Form 941 or Schedule H annually. Free but time-consuming and error-prone.

You’re responsible for getting it right. Mistakes lead to penalties and back taxes.

Required Tax Forms and Deadlines

Schedule H: Filed with your personal tax return annually. Reports household employment taxes.

W-2: Issued to the nanny by January 31. Copy sent to Social Security Administration.

W-4: Nanny completes this when hired. Determines federal withholding amount.

State forms: Vary by state. Some require quarterly filings, others annual.

Estimated Tax Payments

If your nanny tax obligation exceeds $1,000 annually, you may need to make quarterly estimated tax payments or increase W-2 withholding at your own job to avoid underpayment penalties.

Most families increase their W-4 withholding rather than paying quarterly estimates.

Sample Nanny Pay Scenarios

Hourly Rate	Hours/Week	Gross Weekly	Nanny Take-Home	Employer Cost
$18	40	$720	~$540	~$835
$22	45	$1,045	~$780	~$1,210
$25	40	$1,000	~$750	~$1,160
$20	50	$1,100	~$820	~$1,275
$15	30	$450	~$350	~$520

Take-home assumes single filing status, 5% state tax. Overtime included where applicable.

Frequently Asked Questions

Do I Have to Pay Nanny Taxes?

Yes, if you pay a household employee (nanny, housekeeper, etc.) more than $2,700 in a calendar year (2024 threshold). This is federal law. Most states have similar requirements.

Can I Pay My Nanny as a 1099 Contractor?

No. Nannies are household employees under IRS rules, not independent contractors. Misclassifying creates legal problems and penalties for both parties. Always treat nannies as W-2 employees.

What Happens If I Get Audited?

If you paid under the table, you’ll owe back taxes (both employee and employer portions), penalties, and interest going back years. The financial cost usually far exceeds what you “saved” by not paying properly.

Can I Deduct Nanny Costs on My Taxes?

You can claim the Child and Dependent Care Credit for qualifying childcare expenses if you have proper tax documentation (W-2, employer ID number). You can’t claim it if you paid cash under the table.

Do Nannies Get Overtime?

Most nannies qualify for overtime under federal law and many state laws. Live-in nannies have different rules in some states. Check both federal FLSA and your state’s domestic worker laws.

How Much Should I Withhold for Taxes?

Use the IRS tax withholding tables based on the nanny’s W-4. Generally, expect to withhold 15-25% for federal and state income tax plus 7.65% for FICA, totaling 22-33% of gross pay.

What If My Nanny Doesn’t Want Taxes Withheld?

Too bad. It’s the law. You must withhold FICA (Social Security and Medicare) regardless of what the nanny wants. Federal and state income tax withholding is also required unless they qualify for exemption (which most don’t).

Can I Pay More to Avoid Payroll Hassle?

You can use a payroll service ($30-60/month) to handle everything, but you can’t legally skip payroll taxes entirely. The cost of compliance is far less than the cost of penalties for non-compliance.
