Family Employee Tax Exemptions Guide

Hiring a family member to help around the house? The IRS gives you a break on some employment taxes—but which ones depend entirely on the relationship. Spouse, child, parent—each has its own set of rules.

This guide puts every family exemption in one place so you can see exactly what applies to your situation.

For a visual overview with calculator access, see our family member taxes landing page.

The Complete Exemption Matrix

Every family relationship and which taxes apply. Bookmark this—it's the reference you'll come back to.

¹ Social Security and Medicare apply to a parent's wages only if you're widowed or divorced and not remarried (or your spouse can't care for the child) and your parent cares for your child under 18. Federal unemployment is exempt for a parent in every case (IRC §3306(c)(5)).

SUTA (state unemployment) is not in the table because it varies by state. Most mirror the federal exemptions, but Colorado, New York, Washington, and Montana assess state unemployment on a parent even when federal taxes don't apply. Check your state's rules.

Now the details for each relationship.

Spouse as Household Employee

Exemptions: Social Security, Medicare, FUTA — all exempt.

This is the most favorable tax treatment of any family employment arrangement. You skip the entire 15.3% FICA burden plus FUTA.

When it makes sense. One spouse manages the household full-time while the other works outside the home. Paying them formalizes the arrangement and creates earned income for the stay-at-home spouse.

The trade-off. Because FICA is exempt, these wages don't count toward your spouse's Social Security earnings record. If building their individual Social Security credits matters, the exemption actually works against you. However, most married people qualify for spousal benefits (up to 50% of the higher earner's benefit) regardless.

What you still need to do:

• Issue a W-2 with $0 in the Social Security and Medicare boxes
• File Schedule H reporting the wages
• Withhold federal income tax if your spouse requests it on their W-4

Annual savings example on $26,000 in wages: $4,020 compared to a non-family employee.

Child Under 21 as Household Employee

Exemptions: Social Security, Medicare, FUTA — all exempt.

Same treatment as a spouse. Your child under 21 performing domestic work in your home is exempt from all three employment taxes.

Common scenarios:

• Your 17-year-old handles household chores during summer
• Your college-age child (under 21) babysits younger siblings
• Your teenager does yard work, cleaning, or organizing

Important details:

This exemption applies only to your own child (biological, adopted, or stepchild). Nieces, nephews, and other young relatives don't qualify.

The exemption ends the year your child turns 21. If your child turns 21 in June, the exemption covers the whole year up to their birthday, then standard rates apply for the remainder. In practice, most families switch to full taxation starting January 1 of the year they turn 21 to keep things simple.

The income tax angle. Your child's wages are still subject to income tax. But if household work is their only income and it's below the standard deduction ($16,100 for 2026), they likely owe zero federal income tax. They'd fill out a W-4 accordingly.

What you still need to do:

• Issue a W-2 (FICA boxes at $0)
• File Schedule H
• Report their wages

Practical tip: Paying your child for household work teaches financial responsibility and creates documentation if they need to show income for any purpose—scholarship applications, opening a bank account, building a credit history.

Child 21 and Older

Exemptions: None. Standard employment rules apply.

Once your child turns 21, the family exemptions disappear entirely. They're treated exactly like any other household employee:

Common scenario: Your adult child (21+) cares for an aging grandparent in the grandparent's home, and you're paying them. All taxes apply at normal rates.

There's no phase-out or reduced rate. The day your child turns 21 (or, more practically, the next calendar year), the switch is clean.

---

Parent as Household Employee

Exemptions: Social Security, Medicare, and FUTA — all exempt by default. The exception is narrow.

A parent's wages for working in their adult child's home are exempt from all three federal employment taxes by default, under IRC §3121(b)(3) (FICA) and §3306(c)(5) (FUTA). The exemption is broad; the exception is specific.

The default: fully exempt

Whether your parent cares for your child, cleans, cooks, or runs the household, their wages are exempt from Social Security, Medicare, and federal unemployment. A married couple paying a grandparent to watch the kids owes no federal employment taxes at all.

The exception: single parents

Social Security and Medicare apply only when both of these are true:

• Your parent cares for your child who is under 18 (or has a condition requiring care), and
• You are widowed, divorced and not remarried, or living with a spouse who can't care for the child due to a physical or mental condition.

Even then, federal unemployment stays exempt — the single-parent rule reinstates FICA only, never FUTA.

What the exemption means for Social Security

Exempt wages don't build your parent's Social Security credits, because no Social Security tax was paid on them. That only matters if your parent hasn't already qualified for benefits. In the single-parent case where FICA does apply, the wages do build credits.

Example: Mom watches the grandkids

You pay your mom $250/week ($13,000/year) to watch your two kids.

If you're married (filing jointly) — the common case:

If you're a single parent (widowed or divorced and not remarried):

Either way, you may claim the Child and Dependent Care Credit. For the full breakdown, see our guide to paying your mom to babysit.

In-Laws

Exemptions: A spouse's parent qualifies for the parent exemption when you file jointly. Other in-laws don't.

The parent exemption covers "service in the employ of a son or daughter." Your spouse's parent is your spouse's mother or father, so when you file a joint return your spouse is the employing child and the same parent treatment applies: exempt from Social Security, Medicare, and FUTA by default, with the single-parent exception above.

That's why NannyKeeper lists "My parent or my spouse's parent" as one option when you file jointly. If your mother-in-law watches your kids and you file jointly, her wages get the parent treatment — not full taxation.

Other in-laws get no exemption:

Siblings

Exemptions: None.

Your brother or sister working in your home as a household employee gets no special tax treatment. All standard employment taxes apply.

This includes:

• Full siblings
• Half-siblings
• Stepsiblings

Some families assume "family = exemptions," but the IRS limits exemptions to three relationships: spouse, child (under 21), and parent (conditional).

---

SUTA: The State Wildcard

The matrix above covers federal taxes. State unemployment insurance (SUTA) is its own animal.

Some states mirror the federal exemptions. If FUTA is exempt, SUTA is also exempt.

Other states have their own rules entirely. They may exempt spouses and children but not parents, or vice versa, or have no family exemptions at all.

States with notable quirks:

• California and New York have disability insurance and paid family leave programs that may or may not follow family exemptions
• New Jersey has its own rules for family employee exemptions

There's no shortcut here—you need to check your specific state's requirements.

The $3,000 Threshold Still Applies

Family exemptions change which taxes you owe—they don't change whether you owe taxes at all. The household employment threshold is still $3,000 for 2026 (per employee, per calendar year).

If you pay a family member less than $3,000 in a year, no employment taxes are required regardless of the relationship.

If you pay $3,000 or more, the exemptions in this guide determine which taxes apply.

Paperwork Requirements for All Family Employees

Regardless of exemptions, every family employee still needs:

Before they start working:

• W-4 for income tax withholding preferences
• I-9 for employment eligibility (technically required, though enforcement is rare for family)

During the year:

• Pay records — date, hours, gross pay, withholdings
• Quarterly tax payments — either through your W-4 or Form 1040-ES

Year-end:

• W-2 by January 31 — even if some boxes are $0 due to exemptions
• Schedule H with your tax return — reporting wages and whatever taxes do apply

To get started:

• EIN — your employer tax ID (free, 5 minutes)
• State registration — for unemployment insurance in your state

How NannyKeeper Handles Family Exemptions

When you add an employee in NannyKeeper, you identify the relationship—spouse, child, parent, or non-family. We take it from there:

• Automatic exemption application — the right taxes are calculated (or skipped) on every paycheck
• Correct W-2 generation — exempt boxes show $0, taxable boxes show the real numbers
• Schedule H preparation — reflecting the actual taxes owed, exemptions already factored in
• State-specific handling — we know which states follow federal exemptions and which don't

You don't need to memorize this matrix. Just tell us who they are, and we handle the rest.

FAQ

Do family exemptions apply if the family member works in someone else's home?

The exemptions apply when a family member works in your home. If you pay your parent to care for your child in the parent's own home, the IRS still treats this as your household employment—the exemptions still apply because what matters is the employer-employee relationship, not the location.

Can I choose NOT to use the exemptions?

Technically, you shouldn't pay FICA on exempt wages—the IRS doesn't want you overpaying. But the practical concern here is usually about a parent wanting Social Security credits from spousal or child-under-21 wages. Those wages are exempt from FICA by law, and the Social Security Administration won't credit them even if you mistakenly pay FICA tax on them.

What if our relationship changes—say, my stepchild turns 21?

The exemption for children ends the year they turn 21. For practical purposes, switch to standard employment tax calculations starting January 1 of the year after they turn 21. If a marriage ends and a stepchild relationship changes, consult a tax advisor about the transition.

Do I need a separate EIN for each family employee?

No. One EIN covers all your household employees—family and non-family. You file one Schedule H covering everyone, with individual W-2s for each person.

What if I employ both a family member and a non-family nanny?

Each employee gets the tax treatment that matches their relationship to you. Your spouse's paycheck has no FICA; your nanny's paycheck has full FICA. NannyKeeper handles multiple employees with different tax treatments on the same account. Schedule H combines the totals.
