Most parents who put their kids on payroll ask the tax return question a little too late. Usually it happens in February, staring at a W-2 they just generated and wondering what to do with it. Good news: the answer is simpler than you think, and in most cases the answer is "no, your child does not have to file."
Here is the full picture so you can handle it confidently.

Does a Child Who Earns Wages from a Family Business Have to File a Federal Tax Return?
No, not if their earned income is $16,100 or less in 2026.
A dependent child who earns only W-2 wages is required to file a federal return only when that earned income exceeds the standard deduction amount available to them. For 2026, a dependent's standard deduction is the greater of $1,350 or their earned income plus $450, capped at $16,100 (the regular single-filer standard deduction under IRC §63). So if your 14-year-old earns $12,000 in wages from your business, their standard deduction is $12,450 ($12,000 + $450), which fully covers their $12,000 in income. Zero federal taxable income. No filing required.
Pay them $16,100 or less and the same logic holds all the way to the cap. The wages are deductible for your business and tax-free for your child. That is the core of the strategy.
One thing worth noting: do not confuse "not required to file" with "nothing to report." If your child contributed to a Roth IRA that year, you should still file a return. More on that below.
How the Dependent Standard Deduction Actually Works (Show Me the Math)
The rule under IRC §63(c)(5) trips up a lot of parents, so let's walk through it clearly.
The formula: A dependent's standard deduction equals their earned income plus $450, but it can never exceed the regular single-filer standard deduction ($16,100 for 2026) and can never fall below $1,350.
A worked example:
Assume your 13-year-old daughter helps with your e-commerce business. She photographs products, organizes inventory, and manages your business's Instagram drafts. You pay her $15 per hour, 10 hours per week, for 40 weeks of the school year.
- Annual wages: $15 x 10 x 40 = $6,000
- Her standard deduction: $6,000 + $450 = $6,450
- Her federal taxable income: $6,000 minus $6,450 = $0
- Your business deduction: $6,000 at your 32% marginal rate = $1,920 in federal tax savings for you
- FICA taxes owed by either of you (in a sole prop or spousal partnership): $0, because of the exemption under IRC §3121(b)(3)(A)
Total family tax benefit from that $6,000 in wages: $1,920. And your daughter has $6,000 in earned income she can use to fund a Roth IRA, building a retirement account in her teens. That is not a small deal.
If you want to see how this looks across different pay rates and ages, the 2026 tax-free pay guide on kidspayroll.com walks through several scenarios in detail.
When Filing Is Not Required but Still Recommended
Here is where most parents get confused. "Not required" does not mean "never file." There are two situations where filing a return for your child, even at zero income tax owed, makes a lot of sense.
1. Your child contributed to a Roth IRA.
Roth IRA contributions are made with after-tax dollars, so they do not appear on the child's Form 1040. The custodian (the bank or brokerage holding the account) reports the contribution to the IRS on Form 5498. But the IRS has no automatic way to verify that your child had enough earned income to justify that contribution. A filed return showing $6,000 in W-2 wages creates the paper trail that proves the contribution was allowable.
The rule is simple: total Roth contributions for the year cannot exceed the child's earned income for that year (and also cannot exceed the annual contribution limit, which is $7,500 for 2026). If the contribution exceeds either cap, there is a 6% excise tax on the excess under IRC §4973, every year the excess remains in the account. Filing a return is the cleanest way to document the earned income and avoid any future questions.
2. State taxes may require filing even when federal does not.
This is the trap most parents do not see coming. Several states have a much lower standard deduction for dependents than the federal figure. California caps the dependent standard deduction around $5,540. New York caps it around $3,100. So a child earning $8,000 in wages might owe zero federal income tax and still have a few hundred dollars of state income tax exposure. Check your state's rules. Do not assume the federal outcome applies everywhere.
Key Takeaways: Filing Requirements at a Glance
- Not required to file: Dependent child with only earned income at or below $16,100 (2026).
- Recommended to file: Any year the child funded a Roth IRA, even if income is below the threshold.
- Required to file: Earned income exceeds $16,100, or the child has any unearned income (dividends, interest) above $1,350.
- State returns: Check separately. Federal exemption does not guarantee a state exemption.
- Roth IRA contributions: Not reported on the 1040. Documented by Form 5498 from the custodian. The filed return creates the earned-income proof.
Does the Kiddie Tax Apply to My Child's Wages?
No. The Kiddie Tax under IRC §1(g) applies only to a child's unearned income, things like dividends, interest, and capital gains, which get taxed at the parent's rate. W-2 wages are earned income. They are taxed at the child's own rate, which is effectively zero when the wages stay within the standard deduction.
This matters because some parents hear "Kiddie Tax" and panic that the whole strategy falls apart. It does not. The Kiddie Tax is a rule about passive investment income, not about wages your child actually earned working in your business.
What About the W-2 Itself — Do You Need to Issue One?
Yes, absolutely. If your child worked in your business and earned wages, you are required to issue a W-2. This is true even if they owe no federal income tax. The W-2 is what makes the wages deductible on your end and what makes the Roth IRA contribution allowable on their end.
One very common mistake: some parents issue a Form 1099-NEC instead of a W-2, thinking it is simpler. It is not. A 1099 treats your child as an independent contractor, which means their earnings are subject to self-employment tax (15.3%) with no exemption. That erases a big part of the tax benefit. Use a W-2. Always.
For a step-by-step walkthrough of setting up the actual payroll mechanics, running payroll for your child covers the process from setup through year-end W-2 issuance.
Does the Business Entity Type Change Any of This?
It changes the FICA exemption, not the filing rule itself.
The filing threshold works the same regardless of your entity type. But whether you owe payroll taxes (FICA: Social Security and Medicare) on the wages depends entirely on how your business is structured.
| Entity Type | FICA Exempt (Under 18)? | FUTA Exempt (Under 21)? |
|---|---|---|
| Sole proprietorship | Yes (IRC §3121(b)(3)(A)) | Yes (IRC §3306(c)(5)) |
| Single-member LLC (taxed as sole prop) | Yes | Yes |
| Spousal partnership / qualified joint venture | Yes | Yes |
| S-Corporation | No | No |
| C-Corporation | No | No |
| Partnership with non-parent partner | No | No |
If you operate through an S-Corp and want the FICA exemption, the workaround is to have the S-Corp pay a management fee to a separate Family Management Company, a sole proprietorship or single-member LLC you own, which then employs the children. That entity gets the exemption because the direct employer is the parent's sole prop, not the corporation. See how the S-Corp and sole prop structures compare for a fuller breakdown.
The Part the IRS Actually Cares About
Filing a return or not filing a return is a downstream question. The upstream question is whether the wages hold up if the IRS ever looks. They will not audit the tax return filing status. They will audit whether the wages were real.
Real means: genuine age-appropriate work, a reasonable market-rate wage, documented hours, a written job description, and actual payroll records. A 9-year-old can legitimately shred documents, clean the office, or model for marketing photos. A 15-year-old can manage social media, do data entry, or help with bookkeeping. The wages have to match what someone outside the family would charge for the same work, as established in Eller v. Commissioner, 77 T.C. 934 (1981).
Paying your child $8,000 a year to "help around the office" with no time log and no job description is the kind of thing that gets disallowed. Paying them $8,000 a year with a written job description, biweekly time sheets, and a payroll record is the kind of thing that holds up.
The Kids Payroll checklist covers everything you need to keep on file to make the deduction audit-proof.
Bottom Line
If you are paying your child legitimate W-2 wages from your sole proprietorship, single-member LLC, or spousal partnership, and those wages stay at or below $16,100 in 2026, your child does not have to file a federal return. Full stop.
File anyway if they contributed to a Roth IRA that year. It takes about 20 minutes and creates the earned-income documentation that protects the contribution. Check your state's rules separately, because the federal outcome does not automatically carry over.
The Kids Payroll app is built specifically for this setup. It runs compliant payroll for family businesses, generates the W-2 at year-end, and keeps the records you would need if the IRS ever asked a question. Sign up and get your child's payroll running the right way.
FAQ
Does my child have to pay Social Security or Medicare taxes on wages from my sole proprietorship? No. Under IRC §3121(b)(3)(A), a child under 18 employed by a parent in a sole proprietorship or a partnership consisting solely of the child's parents is exempt from FICA taxes. Neither the child nor you as the employer owes Social Security or Medicare tax on those wages.
What if my child earns more than $16,100 from our business? Then they are required to file a federal return. Wages above $16,100 exceed their standard deduction, so they will owe federal income tax on the excess at their own marginal rate, which is typically 10% for low-income earners. This is still far better than those same dollars being taxed at your rate.
Can I pay my child as an independent contractor instead of an employee to skip the W-2? You can, but you should not. A 1099 makes the child a self-employed contractor, which means their earnings are subject to self-employment tax (15.3%) with no exemption. The W-2 plus the FICA exemption in a sole prop is almost always the better structure. See the full comparison at W-2 vs. 1099 for paying your child.
Does filing a return affect my child's dependency status or the Child Tax Credit I claim? No. Filing a return does not disqualify your child from being claimed as your dependent. You continue to claim the Child Tax Credit (subject to the usual income and age rules) regardless of whether your child files their own return.
What is the 6% excise tax on excess Roth contributions and how do I avoid it? Under IRC §4973, if your child's Roth IRA contributions for the year exceed either their earned income or the annual limit ($7,500 for 2026), the excess is subject to a 6% excise tax for every year it stays in the account. To avoid it, remove the excess contribution plus any earnings it generated before the tax filing deadline (including extensions). The best prevention is matching Roth contributions to actual W-2 wages and keeping a copy of the W-2 with the account records.
