Some families run their business from a home office in Texas but spend three months every summer at a lake house in Michigan. Others hire their teenager to manage social media from their college town in a different state. Plenty of parents wonder whether crossing a state line breaks the family payroll strategy they have carefully built. The good news: it does not. But the fine print at the state level deserves a serious look before you hand over a W-2 at tax time.
Written by the Kids Payroll team, grounded in IRC §3121(b)(3)(A) and current IRS guidance on legitimately employing your children in a family business.
TL;DR: Wages you pay your minor child are deductible and FICA-exempt under IRC §3121(b)(3)(A) no matter which state the work happens in. The federal picture is clean. The state picture depends on where the work is performed, where your child is a resident, and what that state's standard deduction looks like for a dependent filer. State standard deductions are often much lower than the federal $16,100 (2026), so plan accordingly.

Yes, You Can Pay Your Child Wages for Work Done Outside Your Home State
The core federal rules do not care about geography. Under IRC §3121(b)(3)(A), wages paid by a parent to a child under 18 in a sole proprietorship or a spousal partnership (qualified joint venture) are exempt from FICA taxes, which means no Social Security or Medicare withholding for either party. Under IRC §3306(c)(5), those wages are also exempt from FUTA (federal unemployment tax) until the child turns 21. Both exemptions follow the employment relationship, not the location of the work.
The child's wages are taxable income to the child under IRC §73, but the dependent standard deduction under IRC §63(c)(5) offsets the first $16,100 of earned income in 2026 (for a child who can be claimed as a dependent). That means zero federal income tax on wages up to that threshold, wherever in the country the work was done.
So from a purely federal standpoint, whether your 15-year-old photographs products at your beach rental, edits videos at your parents' house two states away, or handles customer emails from a summer program dorm, the federal rules hold.
How Multi-State Tax Rules Apply When Your Child Works in More Than One State
Here is where things get more interesting. The United States has 50 state tax systems, and each one has its own rules about who owes tax and when. Two concepts matter for your child: nexus (the connection that gives a state the right to tax someone) and sourcing (which state gets to tax which dollars of income).
Resident state taxation. Your child's state of legal residence taxes all of their income, from anywhere. If your family lives in California and your child earns wages working remotely from your California home office, California taxes those wages. Simple.
Nonresident state taxation. If your child physically performs work in a state where they are not a resident, that state may have the right to tax the portion of wages earned there. This is standard nonresident income tax exposure. Some states have a de minimis threshold (a minimum number of days or a dollar floor before they require a nonresident to file), but many do not.
The reciprocity exception. Many neighboring states have reciprocal agreements that allow residents of one state to pay income tax only in their home state, even if they physically work across the border. If your state has a reciprocity agreement with the state where your child does some work, you may not owe any tax to the second state at all. Check your state's department of revenue website for current agreements, since they change.
The practical result: a child who does real work in two or three states during the year may technically have a filing obligation in each of those states, though credits for taxes paid to other states often eliminate double taxation. The credits do not always eliminate the filing requirement, though. That distinction matters.
The State Standard Deduction Problem (This Is Where Parents Get Surprised)
Federal law gives your dependent child a standard deduction equal to their earned income plus $450, capped at $16,100 for 2026 under IRC §63(c)(5). That wipes out federal income tax on wages up to the full cap. States are not required to mirror that generosity, and many do not.
A few examples of state standard deductions for a single dependent filer:
| State | Approximate Standard Deduction (Dependent Single Filer) |
|---|---|
| California | ~$5,540 |
| New York | ~$3,100 |
| Texas | No income tax |
| Florida | No income tax |
| Illinois | ~$2,550 |
| Washington | No income tax |
If your child earns $12,000 in wages and lives in California, the first $5,540 is sheltered at the state level. The remaining ~$6,460 is subject to California income tax. The federal bill is still zero. But the California bill is real money, and it catches families off guard every year.
This is not a reason to avoid the strategy. It is a reason to plan. Understanding your specific state's rules before you set wages is far smarter than discovering the liability in April.
For a deeper look at how state rules interact with your payroll setup, this breakdown of federal vs. state child labor laws is a good starting point.
A Worked Example: The Johnson Family's Summer Work Arrangement
Say the Johnsons run a sole proprietorship in Illinois. Their 14-year-old daughter, Maya, works on the business year-round but spends eight weeks in the summer at her grandparents' home in Florida helping film and edit videos for the business. The parents pay her $15 per hour.
- Hours per week: 6 during the school year (44 weeks), 15 per week during the 8-week Florida summer.
- Earnings: (6 hours x 44 weeks x $15) = $3,960 + (15 hours x 8 weeks x $15) = $1,800. Total: $5,760.
Federal picture: Maya's wages ($5,760) are well under the $16,100 federal standard deduction. Federal income tax owed: $0. No FICA withholding because the Johnsons operate as a sole proprietorship and Maya is under 18.
Illinois state picture: Illinois has a flat income tax. The Illinois standard deduction for a dependent is approximately $2,550. Maya's Illinois-sourced income (the school-year wages earned while living in Illinois) is roughly $3,960. After the state deduction of ~$2,550, she has about $1,410 of taxable Illinois income. At Illinois's flat rate, that is a modest state tax bill, but it is not zero.
Florida picture: Florida has no individual income tax. The $1,800 earned while physically in Florida creates no state income tax obligation. Good news for the summer work.
Family tax savings from the business deduction: The Johnsons deduct the full $5,760 as a business expense. If their marginal federal rate is 22%, that is $5,760 x 22% = $1,267 in federal tax savings. Add the self-employment tax deduction effect (15.3% SE tax on a pass-through, offset by the wage deduction), and the real savings are closer to $2,100 all-in. Maya pays no federal income tax. The money stays in the family, shifted from a high-rate taxpayer to a low-rate one.
Is it always worth the extra state filing work? Honestly, when the wages are modest and the second state has no income tax (like Florida), it is almost entirely clean. When the second state has a robust income tax and no reciprocity agreement, you may have a nonresident filing obligation to manage. A CPA familiar with multi-state returns is worth the conversation.
What About the FICA Exemption Across State Lines?
The FICA exemption under IRC §3121(b)(3)(A) is purely a federal rule. States do not have their own FICA equivalents in the traditional sense (Social Security and Medicare are federal programs). So the exemption does not change based on which state the work happens in. If you qualify federally, you qualify everywhere.
What states do have are their own unemployment insurance (UI) systems. State unemployment tax is separate from FUTA. Most states follow a similar rule to the federal one and exempt a child employed by a parent in a sole proprietorship or partnership, but you need to verify this with your specific state's department of labor. The rules are not identical across all 50 states.
For a state-by-state breakdown of where these exemptions do and do not apply, this guide to child labor laws by state covers the landscape in detail.
The Entity Structure Question Does Not Change Based on State
One thing that does not shift when you cross state lines is the entity structure requirement. The FICA and FUTA exemptions apply only in a sole proprietorship, a single-member LLC taxed as a sole proprietorship, or a spousal partnership where both partners are the child's parents. An S-Corp, a C-Corp, or a partnership that includes anyone other than the two parents loses the exemption regardless of which state the work occurs in.
If your business is structured as an S-Corp, the standard workaround is to create a separate Family Management Company (a sole prop or parent-owned LLC) that employs your children and bills the S-Corp a management fee. The children are employed by the entity that qualifies for the exemption. This structure needs to be real: a genuine entity with its own bank account, documented services, and a reasonable management fee. You can read more about setting up a family management company and how it works for S-Corp owners in the related posts.
Documentation When Work Spans Multiple States
The IRS and state tax authorities both expect documentation that wages were paid for real, age-appropriate work at a reasonable market rate. When that work happens in more than one location, your documentation needs to reflect it.
Here is what you actually need:
- Time logs that note where the work was performed. If Maya edited videos in Florida, the time log should reflect that. This protects you if a state asks why wages were allocated a certain way.
- A job description that travels with the child. The tasks do not have to change when the child crosses a state line, but the record should make clear the work is ongoing and consistent.
- Payroll records on a regular schedule. Paying every two weeks by direct deposit or check creates a paper trail that is hard to dispute. Paying a lump sum at year-end is an audit flag.
- A W-2 at year-end. If your child funds a Roth IRA with any of these wages, the W-2 is how you document earned income to the IRS. (Roth contributions themselves are not reported on the child's Form 1040; the custodian files Form 5498 with the IRS directly.)
For the full payroll setup process, running payroll for your child step by step walks through exactly what to do from first paycheck to W-2.
Key Takeaways
- The federal FICA exemption (IRC §3121(b)(3)(A)) and FUTA exemption (IRC §3306(c)(5)) apply wherever the work is performed, as long as your entity structure qualifies.
- Each state where your child physically works may have a separate income tax filing requirement, even for modest wages.
- State standard deductions are often a fraction of the federal $16,100 cap, which can create real state tax liability when federal liability is zero.
- Reciprocity agreements between states can eliminate nonresident filing requirements, but you need to verify these for your specific states.
- Documentation should reflect not just what the child did, but where. This matters for state tax allocation and for IRS scrutiny of the arrangement.
- The entity structure requirement does not shift based on geography. Sole prop and spousal partnership qualify; corporations do not, without the management-company structure.
