Nanny Tax Laws and Compliance

Introduction

If you pay someone to care for your kids or an aging parent in your home, you may owe what's commonly called the "nanny tax."

The name is misleading. It refers to a bundle of federal and state employer obligations that apply once you hire someone to work in your household.

Many families stumble here. They classify a nanny as a 1099 contractor to avoid paperwork. They miss the wage threshold that triggers Social Security and Medicare taxes. They skip state registration entirely. Then tax season arrives with zero payroll records to show for it.

This guide covers 2026 thresholds, household-employee classification, required forms, payment options, state rules, deadlines, and the practical steps to get compliant, even if you've already fallen behind.

A quick disclaimer: This article is for general information only and isn't legal or tax advice. Nanny tax rules change frequently and vary by state, so verify current details with the IRS, your state agency, or a licensed tax professional before making filing decisions.

Key Takeaways

  • The 2026 FICA threshold and FUTA threshold are two separate tests — don't confuse them
  • A nanny is generally a W-2 household employee, not a 1099 contractor, when you control the work and schedule
  • Federal compliance typically requires an EIN, payroll records, Form W-2, and Schedule H
  • States can add unemployment insurance, paid leave, workers' comp, and wage-notice rules on top of federal requirements
  • If your situation is complicated or you've missed filings, talk to a qualified tax professional

Who Is a Household Employee, and When Do Nanny Taxes Apply?

The IRS Control Test

The IRS doesn't care what you call your nanny. It cares who controls the work. According to IRS Topic 756, a household worker is your employee if you determine what work gets done and how it gets done, not just the end result.

This test applies to more than nannies. It covers:

  • Regular babysitters
  • Housekeepers
  • Private caregivers for elderly or disabled family members
  • Cooks and household staff

It applies whether the arrangement is full-time, part-time, seasonal, or temporary. A repair person or plumber who runs their own business and controls their own methods isn't your employee. A caregiver who follows your schedule and instructions generally is.

W-2 vs. 1099: Why the Label Doesn't Matter

Some families issue a Form 1099-NEC to a nanny, assuming it makes the worker a contractor. It doesn't. Classification depends on control, not paperwork. A genuine independent contractor typically:

  • Sets their own hours and methods
  • Uses their own tools or supplies
  • Offers services to multiple clients
  • Isn't directly supervised in daily tasks

If none of that describes your nanny, issuing a 1099 doesn't change their legal status. It just increases your audit risk.

Family and Age Exceptions

A few narrow exceptions exist. Wages are generally excluded from FICA and FUTA when paid to:

  • Your spouse
  • Your child under 21
  • A parent (only under specific conditions)

Workers under 18 are typically exempt unless household work is their principal occupation. A student's household job usually doesn't count. These rules have specific conditions, so check current IRS Publication 926 before assuming one applies.

The Two Federal Thresholds

Trigger 2026 Rule
FICA (Social Security/Medicare) Applies once cash wages to one worker reach $3,000 in the calendar year
FUTA (Federal Unemployment) Applies once household wages reach $1,000 in any calendar quarter of 2025 or 2026

Cross the FICA threshold, and you owe employment taxes on the full year's wages, not just the amount over $3,000. FUTA applies separately, only to the first $7,000 in wages per employee, per Publication 926.

What Taxes and Withholding Can Apply?

Once you qualify as a household employer, several federal and state taxes can apply to nanny wages. Here's how each one works.

Social Security and Medicare (FICA)

FICA splits between employer and employee. For 2026, both sides pay 6.2% for Social Security (up to the $184,500 wage base) and 1.45% for Medicare, which has no cap. That's 7.65% total per side.

You have two options for the employee share:

  • Deduct it from their paycheck
  • Cover it yourself (it then counts as additional taxable wages)

Workers earning above $200,000 from you also owe an extra 0.9% Additional Medicare Tax, though that has no employer match.

Federal Unemployment Tax (FUTA)

FUTA is entirely employer-paid. You can never deduct it from a nanny's check. The federal rate is 6.0%, but most employers who pay state unemployment tax on time get a credit of up to 5.4%, dropping the effective rate to 0.6%.

Federal and State Income Tax Withholding

Here's something families often get wrong: federal income tax withholding is not automatic. You're only required to withhold it when all of these apply:

  • Your nanny requests it
  • You agree
  • They submit a completed Form W-4

State income tax withholding is a different story. Some states require it regardless of your federal choice. Beyond withholding, unemployment insurance registration is often mandatory even for small households. Check your state's revenue department directly.

Dependent Care Benefits

If your employer offers a Dependent Care FSA, those pre-tax funds can often go toward paying your nanny's Social Security, Medicare, and FUTA taxes, not just direct care costs. The Child and Dependent Care Credit may also apply, though eligibility limits and coordination rules change, so confirm current figures before filing.

How to Comply: A Step-by-Step Nanny Tax Process

Getting compliant isn't complicated once you break it into stages:

  1. Draft a written agreement. Cover duties, pay rate, schedule, overtime, paid time off, reimbursements, and termination terms. A contract clarifies expectations but doesn't override tax classification.
  2. Get a federal EIN. Apply for free on the IRS website. Check whether your state also requires a separate employer account.
  3. Complete onboarding paperwork. Complete Form I-9 to verify work eligibility, and collect your nanny's legal name, address, and Social Security number for tax reporting. If you've agreed to withhold federal income tax, have them fill out Form W-4.
  4. Set up payroll. Track hours worked, gross wages, overtime, deductions, and net pay every pay period. Options range from manual spreadsheets to payroll software to a payroll service, and each has tradeoffs in cost and time.
  5. Calculate taxes each pay period. Use current IRS withholding tables or a payroll calculator rather than relying on last year's numbers.
  6. Pay throughout the year. Most families cover their nanny tax liability through quarterly estimated payments or by increasing withholding from their own paycheck.
  7. Handle year-end reporting. Issue Form W-2 to your employee and file the employer copy with the Social Security Administration. Report household employment taxes on Schedule H with your personal tax return.
  8. Review annually. Recheck the federal wage threshold, FICA rates, and your state's employer rules before each new tax year.

Already Paying Under the Table?

If you've been paying cash with no records, stop treating your nanny as informal help.

  • Gather whatever wage history you have
  • Get your missing EIN and state registrations
  • Talk to a tax professional about back filings
  • Determine whether amended returns or payment plans are needed

Backup care is separate from household employment. Helpr's employer-sponsored backup-care platform can cover gaps when a regular nanny is out, but once you hire someone directly, payroll, worker classification, and tax filing stay your responsibility as the household employer.

State and Local Nanny Tax Requirements

Federal compliance is only half the picture. States layer on their own rules, which can include:

  • State income tax withholding
  • State unemployment insurance registration
  • Paid sick leave or paid family leave
  • Disability insurance contributions
  • Workers' compensation coverage
  • Wage notices and domestic-worker protections

Rather than guessing based on a generic list, work through this checklist for your specific state:

  1. Identify your state's labor, revenue, unemployment, and workers' comp agencies
  2. Confirm registration deadlines and wage thresholds (some states register households at wage levels well below the federal $3,000 FICA mark)
  3. Check whether workers' comp or disability insurance is mandatory for household employers
  4. Review required wage notices or written contracts for domestic workers
  5. Note record-retention periods, which can differ from federal rules

California, for example, requires unemployment insurance registration once a household pays $750 in a calendar quarter, far below the federal FICA threshold. Confirm your own state's rules before assuming federal compliance is enough.

Deadlines, Records, Mistakes, and Penalties

A Simple Annual Calendar

Milestone Typical Timing
Onboarding (EIN, I-9, W-4) Before or at hire date
Estimated tax payments Quarterly (April, June, September, January)
State filings Varies (often quarterly)
W-2 to employee and SSA By early February following the tax year
Schedule H with Form 1040 By mid-April following the tax year

Verify exact 2026 dates against official IRS and state sources before filing, since deadlines can shift slightly year to year.

What to Keep on File

Keep these household employment records on file:

  • EIN confirmation and employment agreement
  • I-9 and W-4 forms
  • Wage and time records, plus pay stubs
  • Tax payment confirmations and state filings
  • W-2 copies, Schedule H, and related correspondence

The IRS generally expects you to retain these records for at least four years after the filing or payment date, whichever is later.

Common Mistakes That Trigger Trouble

  • Paying cash with no payroll records
  • Issuing Form 1099-NEC to a nanny who's actually a W-2 employee
  • Ignoring overtime or state minimum wage rules
  • Skipping state employer registration
  • Missing the W-2 deadline
  • Assuming a payroll provider removes your responsibility to double-check filings

Late or incorrect filings can lead to back taxes, interest, and penalties, plus separate state enforcement action. Use official IRS penalty schedules or a tax professional to understand your specific exposure. Generic percentages you find online may not apply to your situation.

Quick Action Checklist

  1. Classify the worker correctly as an employee
  2. Confirm you've crossed federal and state wage thresholds
  3. Get your EIN before running payroll
  4. Register as an employer with your state
  5. Set up payroll and withholdings
  6. Make estimated tax payments on schedule
  7. File W-2s and Schedule H by the deadlines
  8. Review thresholds and filings again next year

Frequently Asked Questions

What is the nanny tax threshold for 2026?

For 2026, FICA taxes apply once you pay a household worker $3,000 or more in cash wages for the year. FUTA applies separately once you pay $1,000 or more in any calendar quarter. Verify both figures against current IRS Publication 926 before filing.

What is considered a household employee for tax purposes?

Anyone who performs household work, like childcare, cooking, or elder care, where you control what's done and how it's done. Genuine independent businesses, staffing agencies, and certain family members are limited exceptions.

Is a nanny a W-2 employee or a 1099 contractor?

Generally a W-2 household employee, since families typically set the schedule and supervise the work. Calling someone a contractor or issuing a 1099 doesn't change their actual legal classification.

Do I need an EIN to pay nanny taxes?

Yes, most household employers need a federal EIN to report wages and file Schedule H. Many states also require a separate state employer account or registration number.

What forms do I need to file for a nanny?

Common forms include Form I-9, Form W-4 (if withholding federal income tax), Form W-2, and Schedule H, plus any state-specific forms. Exact requirements depend on your arrangement and location.

What should I do if I have already paid my nanny under the table?

Gather your existing wage records, start compliant payroll going forward, and consult a qualified tax professional about addressing missed federal and state filings. Don't try to conceal past payments.
