Does My Teenager Have to File Taxes?

By Jenna Hale · Last checked August 19, 2026

Three triggers, not one

Almost every confused conversation about this comes from treating it as a single question with a single number. It is not. The IRS page, check if you need to file a tax return, sets out separate thresholds for a dependent, and crossing any one of them on its own makes a return required.

For tax year 2025, meaning the returns being filed in 2026, a teenager who is claimed as a dependent must file if any of these is true:

Those are the numbers for the return filed in 2026. The inflation-adjusted figures for tax year 2026, the returns that will be filed in 2027, come from Rev. Proc. 2025-32, and they are not the same numbers. Any page that gives you one set of figures without telling you which filing season they belong to is a page to close.

Trigger one: money from a job

This is the one most parents are asking about, and for most teenagers it is the one that is not met. More than $15,750 of wages for tax year 2025 is a lot of hours at a part-time rate. A teenager working ten or fifteen hours a week through the school year is usually well underneath it.

The reason the earned-income threshold sits where it does is the standard deduction, and the two figures match year for year. For tax year 2025 the single standard deduction is $15,750, per the IRS’s own summary of the One, Big, Beautiful Bill provisions for individuals and workers. That is the same $15,750 as the filing threshold above, and that is not a coincidence: income under the deduction produces no taxable income, and no taxable income means no federal income tax liability.

A dependent’s standard deduction is calculated differently from an adult’s. It is the greater of a fixed floor, or $450 plus earned income, capped at the regular single standard deduction. For tax year 2026 that floor is $1,350 and the cap is $16,100, per Rev. Proc. 2025-32. Those are next year’s numbers, for the return filed in early 2027, so do not use them to work out whether a return is due for tax year 2025.

Trigger two: money the money made

Unearned income is interest, dividends and capital gains. The threshold is far lower, and it catches families by surprise, usually where a custodial account or an inherited savings account has been quietly earning for years.

For tax year 2025 returns, unearned income over $1,350 makes a dependent’s return required, on its own, regardless of whether they ever had a job.

One thing to watch when you read about this elsewhere. A figure of $2,700 gets repeated constantly as though the IRS published it. It did not. It is two times the $1,350 amount for tax year 2026 in Rev. Proc. 2025-32, and it comes from how the rules for a child’s unearned income are structured, not from a table. If a page prints $2,700 as a plain IRS threshold with no derivation, treat it the way you would treat any number someone copied without reading.

Trigger three: the $400 one, and it is the low one

Net earnings from self-employment of $400 or more create a filing requirement all by themselves, per IRS Topic 554. That is not a typo and it has nothing to do with the other thresholds.

This is the trigger that catches teenagers, because it catches babysitting, lawn mowing, dog walking, tutoring, reselling, and anything paid through a payment app by someone who is not their employer. There is no W-2 for that work, nothing has been withheld along the way, and the tax that becomes due is self-employment tax rather than income tax. It works differently enough that it has its own page: babysitting, mowing and taxes.

“Net” matters. It is what is left after the legitimate costs of the work, not everything that landed in the account.

Required to file, versus should file anyway

This is the distinction the rest of the internet blurs, and it is the useful part of this page.

Required means the three triggers above. Should anyway is a separate calculation, and it comes down to one question: did an employer withhold federal income tax from their paychecks during the year?

If yes, and their income was low enough that they owe none, that money sits with the IRS until a return is filed asking for it. Nobody sends it back automatically. A teenager who earned four thousand dollars over a summer and had federal income tax withheld all season is not required to file, and is leaving that withholding behind if they do not.

Two things this does not apply to:

• Social Security and Medicare withholding does not come back. It is not income tax and filing a return does not reclaim it. That is the single most common misunderstanding about a teenager’s first W-2, and it is unpacked in why is my teen’s first paycheck so small.
• If nothing was withheld, there is nothing to refund. A teenager who correctly claimed exempt on the W-4 usually has no federal income tax withheld, and a return in that case recovers nothing. Not filing is a reasonable answer if no trigger was met.

There is one further reason some families file anyway. Contributing to a Roth IRA requires taxable compensation, and the contribution is limited to that compensation when it is less than the annual limit, which for 2026 is $7,500. A filed return is a clean, dated record of what they earned. If that is on the table, see custodial Roth IRA for teens.

What this looks like

Chloe is seventeen. Through 2025 she worked at a coffee shop, earning around five thousand two hundred dollars, and her stubs show a small amount of federal income tax withheld from most checks. She also has a savings account left by a grandparent that paid a few hundred dollars of interest.

Run the triggers for tax year 2025, the return filed in 2026. Earned income, well under $15,750, so no. Unearned income, a few hundred dollars, under $1,350, so no. Self-employment, none, so no. Chloe is not required to file.

She files anyway, because the withheld federal income tax on those stubs is hers and filing is how she asks for it. What she does not get back is the Social Security and Medicare that came out of every check, which is a different thing entirely and stays where it is.

It takes an hour at the kitchen table with the W-2 in front of them. She does it, not her father, because it is her return and the second time will take twenty minutes.

A short checklist for the kitchen table

1. Find every W-2. One per employer, for the year that just ended.
2. Add up money that came in with no W-2 attached, from apps, from cash, from neighbors. Subtract the real costs of doing that work. If what is left is $400 or more, a return is required.
3. Look up interest and dividends on any account in their name.
4. Compare each of the three totals to its own threshold, for the correct tax year.
5. If none is crossed, check the federal income tax withheld box on the W-2. If there is a number in it, file anyway.
6. Look up the state rules separately.

If step 5 is the reason you are filing, and you want a sense of the scale of it first, the first paycheck estimator breaks a typical teen check into the part that can come back and the part that cannot.

This is general information, not tax advice. Thresholds change every year and the tax year a figure belongs to matters more than the figure itself, so check the linked IRS pages or ask a tax professional before deciding.
