Your teenager gets their first job, earns a paycheck, and suddenly there’s another question to add to the list:

Do they have to file a tax return?

The answer isn’t always as simple as “yes” or “no.”

A teenager’s filing requirement can depend on how much they earn, what type of income they receive, whether they’re considered a dependent, and other circumstances.

Even when a teenager isn’t required to file a federal income tax return, filing one can sometimes still make sense—especially if federal income tax was withheld from their paycheck.

Here’s what parents and teenagers should know.

Does Age Determine Whether a Teenager Has to File Taxes?

No.

There isn’t a general rule that says someone doesn’t have to file taxes simply because they’re under 18.

A 16-year-old can potentially have a federal tax filing requirement just like an adult.

Instead of age, the IRS generally looks at factors such as:

• Earned income
• Unearned income
• Gross income
• Self-employment income
• Dependency status
• Other special circumstances

That’s why two teenagers of the same age could have completely different filing requirements.

What Is Earned Income?

Earned income generally includes money a teenager receives from working.

Examples can include:

• Wages
• Salaries
• Tips
• Other taxable employee compensation
• Net earnings from self-employment

A teenager working an after-school job at a restaurant, grocery store, retail store, or other employer will generally receive a Form W-2 after the end of the year.

The W-2 reports wages and taxes withheld and is an important document when determining whether the teenager needs—or may want—to file a return.

What Is Unearned Income?

Teenagers can also receive unearned income.

This is generally income that doesn’t come directly from performing work.

Examples may include:

• Interest
• Dividends
• Capital gains
• Certain investment income
• Other types of taxable income

This can become particularly important for teenagers who have savings accounts, brokerage accounts, custodial investment accounts, or other investments.

Different filing thresholds can apply to dependents with unearned income.

What If Your Teenager Only Has a Part-Time Job?

Many teenagers work part-time or seasonal jobs.

Whether they must file a federal income tax return depends on their total income and the filing rules that apply for that particular tax year.

For a teenager who can be claimed as someone else’s dependent, special filing rules apply.

The IRS adjusts various tax amounts over time, so parents shouldn’t rely on an income threshold they remember from several years ago.

Instead, review the filing requirements for the specific tax year involved.

Your Teen Might Want to File Even If They Don’t Have To

This is one of the most important things for families to understand.

Not being required to file doesn’t necessarily mean your teenager shouldn’t file.

Suppose your teenager works during summer vacation and federal income tax is withheld from their paychecks.

If their income is low enough that they ultimately don’t owe federal income tax, they may need to file a tax return to claim a refund of federal income tax that was withheld.

The IRS generally won’t automatically send the money back simply because the teenager wasn’t required to file.

A return may need to be filed to claim the refund.

Check the Teenager’s Form W-2

When your teenager receives a W-2, don’t look only at their wages.

Look at the withholding information as well.

If federal income tax was withheld, it may be worth determining whether filing a return could result in a refund.

State income tax may also have been withheld.

State filing requirements are separate from federal requirements, so a teenager may need—or benefit from filing—a state return even when their federal situation is relatively simple.

What If Your Teenager Has a Side Hustle?

This is where things can change quickly.

Today’s teenagers can make money in many ways outside of a traditional part-time job.

Examples include:

• Babysitting
• Lawn care
• Pet sitting
• Tutoring
• Selling products online
• Freelance work
• Content creation
• Photography
• Graphic design
• Gaming or streaming income
• Other gig work

Depending on how the activity is structured, the teenager may be considered self-employed for federal tax purposes.

And self-employment comes with different tax rules.

Self-Employment Income Can Create a Filing Requirement

A dependent teenager with relatively modest self-employment income may still have a federal filing requirement.

Generally, a taxpayer may need to file when net earnings from self-employment are $400 or more, subject to applicable rules.

This surprises many families.

A teenager might earn an amount that seems too small to create an income tax filing requirement but still need to file because of self-employment tax.

Self-employment tax generally relates to Social Security and Medicare taxes for people working for themselves.

Cash Payments Still Count

Getting paid in cash doesn’t automatically make income tax-free.

If your teenager earns money from providing services, the income may still need to be reported even if:

• They’re paid in cash
• They’re paid through a payment app
• They don’t receive a tax form
• They only work occasionally
• The customer is a friend or neighbor

Tax reporting generally depends on the nature and amount of the income—not simply whether a tax document arrives in the mail.

Encourage teenagers with side businesses or gig income to keep records of both their income and qualifying business expenses.

What About Venmo, PayPal, Cash App, and Other Payment Apps?

Receiving money through a payment app doesn’t automatically make the payment taxable.

The reason for the payment matters.

For example, money a parent sends a teenager to reimburse them for a personal purchase is very different from money customers send the teenager for products or services.

Teenagers earning money through payment platforms should maintain records that distinguish business transactions from personal transfers.

Don’t determine whether income is taxable solely based on whether a payment platform issues a tax form.

What If Your Teenager Invests?

Teenagers with investment accounts may face additional tax considerations.

Interest, dividends, and capital gains can potentially create taxable income and may affect whether a return needs to be filed.

Additionally, special rules commonly referred to as the “kiddie tax” can apply to certain children’s unearned income.

Under these rules, some unearned income above applicable thresholds may be taxed using the parent’s tax rate.

The rules can be more complicated than a typical first-job tax return, so families with children who have significant investment income may want professional guidance.

Can Parents Report a Child’s Investment Income on Their Own Return?

In certain situations, parents may be able to elect to report qualifying interest and dividend income of a child on the parent’s return instead of filing a separate return for the child.

This is generally done using Form 8814, Parents’ Election to Report Child’s Interest and Dividends, when the applicable requirements are satisfied.

However, this option isn’t available in every situation and may not always produce the same tax result as filing a separate return.

Can Parents Still Claim a Teenager Who Files Their Own Tax Return?

Potentially, yes.

A common misconception is that if a teenager files their own tax return, the parents automatically lose the ability to claim the teenager as a dependent.

That’s not necessarily true.

Whether a parent can claim a child as a dependent is determined under the applicable dependency rules.

The fact that the teenager files a tax return doesn’t, by itself, determine dependency status.

However, it’s important that the teenager’s return correctly reflects whether they can be claimed as a dependent by another taxpayer.

Incorrectly answering this question can create problems when the parents later file their own return.

Who Actually Files the Teenager’s Tax Return?

If a teenager is capable of preparing and signing their own return, they can generally do so.

Parents often help younger taxpayers understand their tax documents and filing responsibilities.

Depending on the child’s age and circumstances, a parent or guardian may have additional responsibilities.

A teenager’s first tax return can also be a useful opportunity to teach them how taxes work.

They can learn:

• What a W-2 is
• Why taxes are withheld from a paycheck
• The difference between gross pay and take-home pay
• Why tax returns are filed
• How refunds work
• Why self-employment is taxed differently
• Why financial records should be saved

Don’t Forget State Taxes

Federal filing requirements are only one part of the picture.

States can have their own:

• Filing thresholds
• Income tax rules
• Standard deductions
• Dependency rules
• Refund requirements

A teenager who doesn’t owe federal income tax could potentially have a state filing requirement, or they may want to file a state return to recover state income tax that was withheld.

The rules depend on where the teenager lives and works.

What Tax Documents Should Teenagers Keep?

Encourage your teenager to save tax documents rather than throwing them away after filing.

Depending on their situation, they might receive:

• Form W-2
• Form 1099-NEC
• Form 1099-K
• Form 1099-INT
• Form 1099-DIV
• Form 1099-B
• Other tax documents

Teenagers with self-employment income should also maintain records of income and potentially deductible business expenses.

Starting good recordkeeping habits with a first job can make taxes much easier later.

A First Job Is a Good Time to Learn About Form W-4

When teenagers start working as employees, they’ll generally complete Form W-4, Employee’s Withholding Certificate.

This form helps an employer determine the amount of federal income tax to withhold from the employee’s paycheck.

Teenagers shouldn’t simply guess when completing tax forms.

Understanding withholding early can help them learn an important lesson: the amount withheld from a paycheck isn’t necessarily the same as the amount of tax ultimately owed.

A Simple Checklist for Parents

If your teenager earned money this year, ask:

Did they receive a W-2?

Was federal or state income tax withheld?

Did they earn money from a side hustle?

Did their net self-employment earnings reach the filing threshold?

Did they receive interest, dividends, or investment income?

Did they sell investments?

Did they receive any Forms 1099?

Can they still be claimed as your dependent?

Do they have a state filing requirement?

The answers can help determine whether a tax return needs to be filed.

The Bottom Line

Teenagers aren’t automatically exempt from filing taxes because of their age.

Whether a teenager needs to file depends on how much they earned, what type of income they received, whether they’re self-employed, their dependency status, and other factors.

And even when filing isn’t required, filing a return may still be worthwhile if income tax was withheld and the teenager is entitled to a refund.

If your teenager has a traditional job, side hustle, investment account, or multiple sources of income, don’t assume their tax situation is too small to matter.
