Can Grandparents Hire Grandchildren Tax-Free?

Grandparents who run businesses often look at what their own kids are doing, paying grandchildren wages through the family business, and wonder if they can do the same thing. It is a fair question. The tax savings look real, the work can be real, and the grandkids are right there. So what is the hold-up?

The hold-up is a single line in the tax code. And once you understand it, you can work around it.

TL;DR: The FICA payroll tax exemption under IRC §3121(b)(3)(A) only applies when a parent employs their own child under 18 in a sole proprietorship or spousal partnership. Grandparents do not qualify for that specific exemption. However, grandparents can still legally hire grandchildren, pay them reasonable wages as a deductible business expense, and let those grandchildren earn up to the standard deduction ($16,100 for 2026) completely federal-income-tax-free. FICA will apply, but the income tax savings are still significant.

Can Grandparents Hire Grandchildren for Tax-Free Wages?

Yes, grandparents can hire grandchildren and pay them real wages for real work. Those wages are deductible as a business expense, just like any other employee cost. And grandchildren, like any young worker, owe zero federal income tax on earned income up to the standard deduction (currently $16,100 for single filers in 2026 under IRC §63).

What grandparents cannot do is skip FICA. The payroll tax exemption in IRC §3121(b)(3)(A) reads specifically: "services performed by a child in the employ of his father or mother." That means the biological (or adoptive) parent must own the business. Grandparents, aunts, uncles, and other relatives do not qualify under that language.

So the income tax benefit is still there. The FICA savings are not, at least not automatically.

What the FICA Exemption Actually Says (and Who It Leaves Out)

FICA stands for Federal Insurance Contributions Act, which covers both Social Security (6.2%) and Medicare (1.45%) taxes. When a parent hires their own child in a sole proprietorship, both the employer and employee portions of FICA are waived until the child turns 18. That is a combined 15.3% in payroll taxes that simply disappears.

IRC §3121(b)(3)(A) is narrow on purpose. It covers:

A child employed by a parent
In a sole proprietorship or a partnership where both partners are the child's parents (a qualified joint venture)
Child must be under 18 for the FICA exemption, under 21 for the FUTA exemption under IRC §3306(c)(5)

Grandparent-owned businesses do not fit that definition. Neither do S-corps, C-corps, or partnerships that include a non-parent partner, which is why even parents lose the exemption if they run payroll through the wrong entity. For a deeper look at how entity type changes the math, our breakdown of sole proprietorship vs. S-corp structures for paying kids walks through exactly what gets lost and when.

The result for grandparents: FICA applies, just as it would for any unrelated employee. That is not nothing. But the income tax side of the picture still works beautifully.

The Income Tax Math Still Works. Here Is the Proof.

Let's run the actual numbers.

Assumptions:

Grandparent owns a sole proprietorship with $150,000 in net profit
Grandchild is 15 years old, works 6 hours a week at $14/hour doing social media, filing, and light admin tasks
52 weeks of work per year
Grandparent is in the 24% federal marginal income tax bracket

Step 1: Calculate annual wages 6 hours × $14/hour × 52 weeks = $4,368 per year

Step 2: Business deduction for grandparent The $4,368 shifts out of the grandparent's taxable income. At 24%, that is: $4,368 × 0.24 = $1,048 in federal tax savings for the grandparent.

Step 3: Federal income tax owed by grandchild $4,368 is well below the $16,100 standard deduction. The grandchild owes $0 in federal income tax on those wages under IRC §63.

Step 4: FICA cost Because the grandparent-grandchild relationship does not qualify for the §3121(b)(3)(A) exemption, FICA applies. The employer pays 7.65% and the grandchild's check is reduced by 7.65% as well.

Employer FICA: $4,368 × 0.0765 = $334
Employee FICA withheld: $4,368 × 0.0765 = $334

Net result: The grandparent saves $1,048 in income tax but pays $334 in employer FICA. Net benefit to the grandparent: roughly $714 in tax savings on $4,368 of wages. The grandchild brings home real money, builds work experience, and can sock the earnings into a Roth IRA. Not bad for part-time work over a school year.

One Workaround: The Family Management Company

Here is where it gets interesting. If the grandparent's business is structured as an S-corp or C-corp, they are already in the same boat as parents who use those entities: FICA applies regardless. But there is a structure that can restore the exemption even for grandparents, at least indirectly.

The setup works like this:

The grandchild's parent (the grandparent's own adult child) opens a sole proprietorship or single-member LLC, sometimes called a Family Management Company.
The grandparent's business pays a management fee to that company for administrative or marketing services.
The parent's sole proprietorship employs the grandchild and pays them wages from those management fees.
Because the employer is now the parent's business, IRC §3121(b)(3)(A) applies and FICA drops off.

This is the same structure that business owners running S-corps use to preserve the exemption. The key requirement is that the Family Management Company must be real: a real entity, a real bank account, real invoices for real services, and wages that match what the market would pay for the work. A sham arrangement does not hold up. For a full walkthrough of how to build this correctly, see our guide on setting up a Family Management Company.

Is it always worth the added structure? No. If the grandparent runs a simple sole proprietorship and the grandchild is only earning a few thousand dollars a year, the FICA cost on small wages may not justify a separate entity. Run the numbers for your specific situation before adding complexity.

What Grandparents Still Need to Do (The Part the IRS Cares About)

Whether the employer is a parent or a grandparent, the legitimacy rules are identical. Courts like U.S. v. Renfrow make clear that the IRS will disallow the deduction if the work is not real, documented, and appropriately compensated. Here is what you actually need to do:

Assign real, age-appropriate tasks. For a teenager, think social media management, video editing, filing, customer service support, or product photography. Not lawn mowing at grandma's house.
Pay market-rate wages. Look up what a local business would pay a 15-year-old for the same work. That is your ceiling and your defense.
Keep time logs. A simple spreadsheet or app showing dates, hours, and tasks is enough. Keep it current.
Issue a W-2 at year end. Not a 1099. A 1099 triggers self-employment tax on the grandchild, which wipes out the income tax savings fast. A W-2 is correct for an employee. See why a W-2 beats a 1099 for family employees.
Actually run payroll. That means withholding the right amounts, depositing taxes on schedule, and filing the quarterly 941s or annual 944. If this sounds like a lot, payroll software handles most of it.
Check state labor law. Federal rules set the floor; states often add restrictions on hours and minimum wages for minors. Our state-by-state child labor law guide is a good starting point.

One more thing grandparents often miss: state income tax. Even if the grandchild owes nothing federally, states like California and New York have much lower standard deductions. If you are in one of those states, the grandchild may owe a small state tax bill. Plan for it.

Roth IRA: The Real Prize for the Grandchild

Here is the benefit that outlasts everything else. Once the grandchild has earned income, they can contribute to a Roth IRA up to the lesser of their earned income or the annual contribution limit (up to $7,500 for 2026). The grandparent or parent can fund the contribution on the grandchild's behalf; the grandchild just needs the earned income to create eligibility.

A grandchild who earns $4,000 a year from ages 13 to 18 and puts it all in a Roth IRA is sitting on decades of tax-free compounding by the time they retire. The tax savings today are nice. The Roth balance at 65 is life-changing. For the full rules on Roth IRAs for minors, our Roth IRA for kids guide covers contribution limits, custodial accounts, and what happens when the child becomes an adult.

Key Takeaways

Grandparents can hire grandchildren. The wages are deductible and the grandchild pays no federal income tax up to $16,100 (2026 standard deduction).
Grandparents cannot claim the IRC §3121(b)(3)(A) FICA exemption directly. That is reserved for parent-owned sole proprietorships and spousal partnerships.
A Family Management Company owned by the grandchild's parent can restore the FICA exemption, but it must be a real operating entity.
Documentation, W-2s, and market-rate wages are non-negotiable regardless of who owns the business.
The Roth IRA opportunity is the same for grandchildren as for any minor with earned income.

Frequently Asked Questions

Can a grandparent claim the FICA exemption when hiring a grandchild? No. IRC §3121(b)(3)(A) applies only when a parent employs their own child in a sole proprietorship or parents-only partnership. The grandparent-grandchild relationship does not qualify.

Are grandchild wages still deductible for a grandparent's business? Yes. Wages paid to a grandchild for real, documented work are a deductible business expense under the same rules that apply to any employee. The grandchild also owes no federal income tax on wages up to the standard deduction.

What if the grandparent runs an S-corp? S-corp owners cannot use the §3121(b)(3)(A) exemption even when employing their own children. A Family Management Company (a sole prop or single-member LLC owned by the grandchild's parent) is the common solution, whether the grandparent's business is an S-corp or any other entity.

Does a grandchild need a W-2 or a 1099? A W-2. Grandchildren employed by a grandparent's business are employees, not independent contractors. Issuing a 1099 would make the grandchild's income subject to self-employment tax, which eliminates most of the tax benefit.

Can the grandchild contribute to a Roth IRA from these wages? Yes. Any minor with earned income can contribute to a Roth IRA up to the lesser of their earned income or the annual limit. A grandparent or parent can fund the account on the child's behalf as long as the earned income exists.
