Household Employer Payroll: Nanny Tax and Schedule H Requirements

Household employers occupy a distinct and often underestimated segment of the US payroll compliance landscape. When a private individual hires a nanny, housekeeper, caregiver, or similar domestic worker and pays that worker above a statutory threshold, federal and state employment tax obligations apply — collectively known as the "nanny tax." The primary federal reporting mechanism is Schedule H, filed as an attachment to the employer's individual income tax return. Understanding how these obligations are structured, when they trigger, and how they differ from business payroll is essential for compliance with IRS requirements and applicable state labor laws.

Definition and scope

The term "nanny tax" refers to the suite of employment taxes owed by a household employer — Social Security, Medicare, and federal unemployment tax — along with the corresponding federal income tax withholding obligations that may apply. The legal basis is established under the Federal Insurance Contributions Act (FICA) and the Federal Unemployment Tax Act (FUTA), both administered by the IRS.

A household employee is defined under IRS Publication 926 as a worker who performs domestic services in the employer's private home, where the employer controls not only the work to be done but also how it is done. Workers who fall into this category include nannies, au pairs, housekeepers, private nurses, gardeners, and home health aides. Independent contractors who set their own methods and tools — such as a cleaning company that sends different employees — are excluded from this classification. The distinction is governed by the same employee classification standards applied in commercial payroll, but applied within the domestic context.

For 2023, the cash wage threshold that triggers FICA obligations was $2,600 per year per household employee (IRS Publication 926, 2023). The FUTA threshold is $1,000 in cash wages in any calendar quarter (IRS Publication 926). Both thresholds are subject to annual inflation adjustments.

How it works

Household employer payroll operates through a reporting cycle tied to the individual employer's annual federal income tax return rather than the quarterly business payroll cycle used by commercial employers. This is a structural difference from Form 941-based payroll.

The core mechanism:

1. Wage tracking: The employer tracks all cash wages paid to each household employee throughout the calendar year.
2. FICA withholding: Once wages exceed the annual threshold, the employer withholds 6.2% Social Security tax and 1.45% Medicare tax from the employee's wages, and matches those amounts as the employer's share — a combined FICA rate of 15.3% split equally between employer and employee (IRS FICA reference, ecfr.gov §31.3121).
3. Federal income tax withholding: Optional unless the employee requests it via Form W-4.
4. FUTA calculation: The employer owes 6% federal unemployment tax on the first $7,000 in wages per employee per year, reduced by a credit of up to 5.4% for timely state unemployment tax payments, yielding an effective rate as low as 0.6% (IRS Topic No. 759).
5. Schedule H filing: All household employment taxes are reported on Schedule H (Form 1040), filed with the employer's annual Form 1040 by the April tax deadline.
6. W-2 issuance: The employer must furnish the household employee a Form W-2 by January 31 of the following year and file copies with the Social Security Administration.

State unemployment insurance obligations run parallel to the federal cycle. Most states require household employers to register separately with the state workforce agency and file quarterly state unemployment returns — a process analogous to state unemployment tax compliance in business payroll. State income tax withholding rules vary by jurisdiction.

Common scenarios

Scenario 1 — Full-time nanny employed year-round: An employer paying a nanny $800 per week ($41,600 annually) owes FICA on all wages, FUTA on the first $7,000, and must issue a W-2. Schedule H consolidates all of these obligations at tax time.

Scenario 2 — Part-time housekeeper below threshold: An employer paying a housekeeper $50 per week for 48 weeks ($2,400 annually) in 2023 falls below the $2,600 FICA threshold. No FICA obligations apply, though recordkeeping is still advisable. If wages exceed $1,000 in any single quarter, FUTA still applies.

Scenario 3 — Elderly care at home: A family hiring a private home health aide pays $3,500 over the year. FICA applies. If the aide's wages exceed the applicable quarterly threshold, FUTA also applies. Employers who engage workers through a licensed placement agency may shift some obligations, but only if the agency is the legal employer of record — an independent contractor payments distinction that requires careful review.

Scenario 4 — Multiple domestic workers: An employer with both a nanny and a gardener treats each worker as a separate employee. The thresholds apply per worker, and Schedule H aggregates the combined tax liability.

Decision boundaries

The structural dividing lines that determine household employer obligations:

Household employers differ from commercial small business payroll operators in one critical structural way: they do not file Form 941 or Form 940. Those forms are reserved for business entities. Household employers consolidate all federal obligations onto Schedule H, attached to Form 1040. This makes the April tax filing deadline the primary annual compliance event, rather than quarterly deposit deadlines — though estimated tax payments may be required to cover the additional Schedule H liability during the year.

Employers who also operate a business and have household employees may, under certain IRS provisions, include household taxes in their business payroll deposits to avoid underpayment penalties, but this requires careful coordination. For an overview of how household employer obligations fit into the broader national payroll compliance framework, the National Payroll Authority reference network covers the full spectrum of domestic and commercial payroll obligations.

State-level obligations are not captured by Schedule H. Household employers in states with income tax, mandatory state unemployment insurance for domestic workers, or state-level paid family leave programs must register, withhold, and report independently from the federal Schedule H process. States such as California and New York have historically maintained more stringent domestic worker employment requirements, including minimum wage provisions that exceed federal floors and additional recordkeeping mandates.

Payroll recordkeeping standards apply to household employers just as they do to commercial entities. The IRS recommends retaining Schedule H, copies of W-2 forms, and supporting wage records for at least 4 years from the due date of the related tax return (IRS Pub. 926).
