A teen may need to file a federal tax return even if a parent claims them as a dependent. For the 2025 tax year—returns generally filed in 2026—the answer depends on the teen’s income type and amount, as well as special rules for self-employment and investment income. A return may also be worthwhile when filing is not required, such as to claim a refund of federal income tax withheld from a paycheck.
Does a teen have to file a tax return if a parent claims them?
Possibly. Dependency status does not, by itself, excuse a teen from filing. For 2025, a single dependent under age 65 generally must file if any one of the following tests is met, according to the IRS filing guidance and dependent chart:
| Income test | 2025 filing threshold for a single dependent |
|---|---|
| Unearned income | More than $1,350 |
| Earned income | More than $15,750 |
| Gross income | More than the larger of $1,350 or earned income (up to $15,300) plus $450 |
These are tax-year-specific amounts, not permanent limits. Use the IRS filing checker or the dependent chart for the year in question and the teen’s full circumstances. Other filing situations may apply, and a filing requirement can exist even if no tax is ultimately owed.
Which kinds of income count?
The threshold calculation depends on whether income is earned or unearned, and on total gross income. The IRS generally treats wages, salaries, tips, professional fees, and taxable scholarship or fellowship grants as earned income. Taxable interest, ordinary dividends, and capital-gain distributions are examples of unearned income. Gross income combines earned and unearned income.

For example, a teen with a part-time job and taxable investment income should not compare only their paycheck with the earned-income threshold. The unearned-income and combined gross-income tests may also matter.
Does a teen with a gig job have to file?
Usually, a teen with net earnings of $400 or more from self-employment must file a federal return, even if the work is temporary, part-time, or a side job. The IRS includes services, online sales, and tasks completed through a platform among examples of gig activity. See the IRS gig-economy tax guidance.
Rank #2
Independent-contractor income is not the same as wages from an employee job: withholding and filing obligations can differ. An independent contractor may also need to make estimated tax payments. If it is unclear whether the teen is an employee or contractor, the IRS advises checking worker status.
Can investment income trigger a separate child-tax rule?
It can. For 2025, Form 8615 may be required when a child has more than $2,700 of unearned income and meets the IRS’s other conditions. Those conditions include a filing requirement, an applicable age or student-and-support category, at least one living parent at year-end, and not filing a joint return.
The age and support categories include a child under 18; an 18-year-old whose earned income did not exceed half of their support; or a full-time student age 19 through 23 whose earned income did not exceed half of their support. The rule does not mean every teen’s investment income is automatically taxed at a parent’s rate. Review the current Form 8615 instructions to determine whether the child and income meet the requirements and how the tax is calculated.
Why file if the teen is not required to?
Filing may be useful even when income is below the mandatory filing threshold. If an employer withheld federal income tax from the teen’s pay, filing may be necessary to claim a refund. The IRS also identifies refundable credits and estimated tax payments as possible reasons to file. Its filing guidance puts it simply: “It might pay you to file even if you don’t have to.”

- Identify the tax year. Use that year’s IRS thresholds; the figures above apply to 2025 income.
- Gather income records. Include wages and tips, taxable scholarship income, taxable interest and dividends, capital-gain distributions, and self-employment records.
- Separate earned, unearned, and self-employment income. Compare earned, unearned, and combined gross income with the dependent filing tests, and check separately for the $400 net self-employment trigger.
- Check the investment-income conditions. If unearned income exceeds $2,700 for 2025, review the Form 8615 age, support, parent, and filing conditions.
- Consider a return for a refund or credit. Check withholding and payments even if none of the mandatory filing tests appears to apply.
- Check state requirements separately. Federal thresholds do not determine whether a state return is required; state rules may differ.
For an individual calculation or an unusual situation, consult the current IRS instructions or a qualified tax professional.
