Yes, minors do have to pay taxes when their income crosses the IRS thresholds, and the rules turn on how much a child earned and what kind of income it was. For the 2026 tax year, a dependent child with wages must file a federal return once earnings top $16,100, but investment income triggers a filing requirement at just $1,350. Self-employment earnings of $400 or more require a return at any age. The tax liability belongs to the child, even when a parent handles the paperwork.
When a Minor Must File
The IRS draws a sharp line between earned income (wages, tips, self-employment) and unearned income (interest, dividends, capital gains). Each has its own threshold, and the numbers shift each year with inflation.
For 2026, a single dependent under 65 must file if any of the following apply:
- Earned income only: more than $16,100, which matches the standard deduction for single filers.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- Unearned income only: more than $1,350.2Internal Revenue Service. Rev. Proc. 2025-32
- Both earned and unearned: gross income exceeds whichever is larger, $1,350 or earned income plus $450.2Internal Revenue Service. Rev. Proc. 2025-32
The unearned-income bar sits so much lower because of how the dependent standard deduction works. A dependent’s standard deduction equals the greater of $1,350 or their earned income plus $450, capped at $16,100. A teenager earning $8,000 at a summer job gets an $8,450 standard deduction and owes nothing. A child with $2,000 in dividend income gets only $1,350 of shelter, leaving $650 exposed to tax.
Self-Employment and Gig Income
Babysitting, lawn care, reselling online, freelance design work. If a minor works for themselves rather than an employer, the filing threshold drops sharply. A minor with net self-employment earnings of $400 or more must file a return regardless of whether they owe income tax.3Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) That rule applies at any age.
On top of regular income tax, self-employed minors owe self-employment tax, which covers Social Security and Medicare. The combined rate is 15.3 percent on net earnings: 12.4 percent for Social Security on earnings up to $184,500 in 2026, plus 2.9 percent for Medicare on all earnings.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates The child reports this on Schedule SE attached to Form 1040.
Because no employer is withholding from gig income, the IRS may expect quarterly estimated payments. These are required when a filer expects to owe at least $1,000 in tax for the year after subtracting withholding and refundable credits.5Internal Revenue Service. 2026 Form 1040-ES, Estimated Tax for Individuals Most teens with modest side income won’t hit that mark, but a minor running a successful small business can. Missing estimated payments leads to an underpayment penalty on top of the tax itself.
When Filing Pays Off Even If It Isn’t Required
Even when a minor falls below every filing threshold, filing can be worth it. The most common reason is recovering federal income tax that an employer already withheld. A teenager who earns $4,000 over the summer will likely have federal tax taken from each paycheck. Since $4,000 sits well below the $16,100 filing threshold, the child’s actual liability is zero, and filing a return is the only way to get the withheld money back.6Internal Revenue Service.

Filing also matters if the minor qualifies for a refundable tax credit, such as the earned income tax credit for older teens. The IRS will not send refund money without a filed return, no matter how clear the entitlement.
A minor with earned income can also contribute to a custodial Roth IRA, up to $7,500 or their total earned income for the year, whichever is less.7Internal Revenue Service. Retirement Topics – IRA Contribution Limits Filing a return documents the earned income and creates a paper trail for the contribution. A parent or grandparent can fund it on the child’s behalf, as long as the child actually earned at least that much.
How the Kiddie Tax Works
Congress created what’s informally called the kiddie tax to stop parents from shifting investment portfolios into their children’s names and taking advantage of a child’s lower bracket. Above a certain threshold, a child’s investment income gets taxed at the parent’s rate instead.
The kiddie tax applies when all of the following are true:
- The child had more than $2,700 in unearned income for 2026.8Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax)
- The child was under 18 at year-end, or was 18 (or a full-time student aged 19 through 23) and did not earn more than half of their own support.9Internal Revenue Service. Instructions for Form 8615 (2025)
- At least one parent was alive at year-end.
- The child does not file a joint return.
The math breaks into three layers. The first $1,350 of unearned income is sheltered by the child’s standard deduction and owes no tax. The next $1,350 is taxed at the child’s own rate, usually 10 percent. Everything above $2,700 gets taxed at the parent’s marginal rate, which can run as high as 37 percent.10Internal Revenue Service. Federal Income Tax Rates and Brackets The child calculates this on Form 8615, attached to their own Form 1040.11Internal Revenue Service. Instructions for Form 8615 (2025)
Unearned income includes more than stock dividends. Interest from savings accounts, capital gains from selling investments in a custodial (UTMA or UGMA) account, and even the taxable portion of a scholarship all count. Scholarship money spent on tuition and required course materials is tax-free, but amounts covering room and board or other living expenses are taxable.12Internal Revenue Service.

Reporting the Child’s Income on the Parent’s Return
Parents can skip the child’s separate return entirely by reporting the child’s income on their own return using Form 8814. This election is available only when the child’s income consists solely of interest and dividends (including capital gain distributions), the child’s gross income was less than $13,500, no estimated tax payments were made for the child, and no federal income tax was withheld from the child’s income.13Internal Revenue Service. Instructions for Form 8814 (2025) The convenience comes with a trade-off: the parent’s adjusted gross income rises, which can affect eligibility for other tax benefits. For children with larger investment portfolios, filing a separate return with Form 8615 often produces a better result.
Working for a Parent’s Business
When a child works for a parent’s sole proprietorship, or a partnership where both partners are the child’s parents, the payroll tax rules are noticeably more generous. Wages paid to a child under 18 are exempt from Social Security and Medicare taxes entirely. Wages paid to a child under 21 are exempt from federal unemployment tax.14Internal Revenue Service. Family Employees
The child still owes regular income tax on those wages, but the standard deduction shelters the first $16,100. A parent who pays their 16-year-old $10,000 for legitimate work in the family business gets a deductible business expense, and the child pays zero federal tax: no income tax, no Social Security, no Medicare. The work has to be real and the pay reasonable for the job. The exemption does not apply if the business is structured as a corporation or if the child is employed through a payroll service that routes payments through a corporate entity.
Filing, Signing, and Deadlines
A minor signs their own return. If the child is too young to write their name, a parent or guardian signs the child’s name followed by their own signature and “parent (or guardian) for minor child.”15Internal Revenue Service. Return Signature
If the return isn’t ready by April 15, the minor or their parent can request an automatic six-month extension to October 15 by filing Form 4868 or making an electronic payment marked as an extension.16Internal Revenue Service. Need More Time to File, Request an Extension An extension gives more time to file, not more time to pay. Any tax owed is still due April 15.
Filing late when the return shows a balance triggers a failure-to-file penalty of 5 percent of the unpaid tax for each month the return is overdue, capped at 25 percent.17Internal Revenue Service. Failure to File Penalty Interest also accrues on unpaid balances. The current underpayment rate for individual taxpayers is 7 percent annually, adjusted quarterly based on the federal short-term rate plus three percentage points.18Internal Revenue Service. Quarterly Interest Rates These charges apply to the minor’s account, not the parent’s, even if the child is 14.
A minor who owes a balance can pay electronically through IRS Direct Pay using a bank account, or by debit or credit card.19Internal Revenue Service. Types of Payments Available to Individuals Through Direct Pay A parent usually handles the payment in practice, but the IRS records it against the minor’s Social Security number.
