For most families, yes: a 16-year-old working a part-time or summer job can claim exempt on their W-4 without a problem. For 2026, a dependent child won’t owe federal income tax unless earned income exceeds $16,100, and most teens in entry-level jobs come in well under that.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your teen had no tax liability last year and expects none this year, claiming exempt is often the smarter choice. It keeps their paychecks whole and avoids filing a return just to recover money that shouldn’t have been withheld in the first place.
The Two Boxes the IRS Actually Checks
Any employee can claim exemption from federal income tax withholding, but only if two things are true at the same time. They owed zero federal income tax for the prior year, and they expect to owe zero federal income tax for the current year.2Internal Revenue Service. Form W-4 2026 Employees Withholding Certificate
For a 16-year-old starting a first job, the prior-year condition is almost always met on autopilot. No job last year means no income and no liability. Even a teen who worked last summer probably earned less than the filing threshold and owed nothing. The current-year condition is the one that takes a little arithmetic, and that math comes down to the dependent standard deduction.
How Much a Dependent Can Earn Tax-Free in 2026
The key number for a working teen is the dependent standard deduction. It wipes out income before any tax applies. For 2026, that deduction equals the greater of $1,350 or earned income plus $450, capped at $16,100.3Internal Revenue Service. Revenue Procedure 2025-32 That cap matches the regular standard deduction for a single filer.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
In practice, the formula tracks wages almost dollar for dollar. A teen earning $10,000 gets a standard deduction of $10,450, covering all of it. A teen earning $15,000 gets $15,450. Only once earnings cross $16,100 does taxable income appear, and only on the amount above that line. A teen earning $17,000 would owe tax on just $900.
The $1,350 floor exists for dependents with little earned income but some interest or dividends. For a teen whose income comes from a paycheck, the earned-income-plus-$450 formula is what matters, and it makes claiming exempt a straightforward call for anyone earning under $16,100.
How to Claim Exempt on the 2026 W-4
The mechanics are simpler than most people expect. Your teen fills out Step 1 (name, address, Social Security number, filing status) and Step 5 (signature and date). Then they write “Exempt” in the space below Step 4(c) as instructed on the form and skip every other step.2Internal Revenue Service. Form W-4 2026 Employees Withholding Certificate No allowances, no worksheets.
Claiming exempt is not permanent. The exemption expires at the end of the calendar year. To stay exempt into the next year, your teen has to submit a fresh W-4 to their employer by February 15.4Internal Revenue Service. Topic No. 753, Form W-4 Employees Withholding Certificate Miss that date and the employer switches to withholding as if the employee is single with no adjustments.
What Claiming Exempt Does Not Stop
Exempt stops federal income tax withholding only. Social Security and Medicare, together called FICA, are a separate withholding that the W-4 doesn’t touch. Every paycheck will still show a 7.65% FICA deduction: 6.2% for Social Security and 1.45% for Medicare.5Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates It applies at any age and any income level, and the W-4 offers no opt-out. One narrow carve-out exists for a child under 18 working for a parent’s sole proprietorship or a parents-only partnership, but not for a corporation, even one the parents own.6Internal Revenue Service. Family Employees For a teen working at a restaurant, retail store, or any outside employer, FICA comes out automatically.
State income tax is also separate. The W-4 is a federal form. Most states that collect income tax have their own withholding certificate, and claiming exempt federally does not automatically exempt your teen from state withholding. Some states piggyback on the federal form; others require a completely separate document. Your teen should ask the employer which state form applies and whether the state offers a similar exemption. Eight states have no individual income tax at all, so this doesn’t come up everywhere.
When Exempt Might Be the Wrong Call
A few situations change the answer.
Unearned Income From Savings or Investments
Wages are earned income, but some teens also receive interest from a savings account, dividends from investments, or capital gains in a custodial brokerage account. Unearned income follows stricter rules. For 2026, a dependent must file a tax return if unearned income exceeds $1,350.3Internal Revenue Service. Revenue Procedure 2025-32 Past that, the kiddie tax applies, and part of the income can end up taxed at the parent’s marginal rate. Exempt on the W-4 can still be fine for wage withholding, but the investment side may generate its own tax. The two types of income don’t cancel each other out for filing purposes.
Self-Employment Instead of Wages
Teens who earn money through freelance work, lawn care, tutoring, or selling items online often have self-employment income, not wages. There’s no W-4 because there’s no employer withholding. The filing trigger is much lower too. If net earnings from self-employment reach $400, the teen has to file a return and pay self-employment tax even if total income is far below $16,100.7Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Income tax will usually still be zero, but the 15.3% self-employment tax on net earnings applies anyway. A teen who nets $2,000 mowing lawns owes roughly $283 in self-employment tax with no income tax due. This one surprises people every year.
Earnings Climbing Past the Threshold
If your teen claims exempt and then earns more than $16,100, no federal income tax will have been withheld all year. They’ll owe the full amount when they file, in one lump. For most teens the amount is small. Someone earning $18,000 would owe tax on $1,900 at the 10% bracket, which comes to $190. Annoying, not ruinous. The IRS generally doesn’t impose an underpayment penalty if the total owed is under $1,000.8Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty A teen would need to earn well over $26,000 before that penalty becomes a realistic worry.
A separate $500 civil penalty exists for false information on a W-4 without reasonable basis for the claim.9Office of the Law Revision Counsel. 26 USC 6682 – False Information With Respect to Withholding In practice it targets people gaming the system, not a teenager who genuinely expected to stay under the threshold and then picked up extra December shifts. If income is trending well past $16,100, the right move is a fresh W-4 dropping the exempt claim so withholding starts immediately.
If They Didn’t Claim Exempt and Should Have
The money isn’t lost, but it isn’t automatic either. An employer that withholds federal income tax will keep withholding based on the default single-filer calculation, and the IRS won’t send a refund on its own. Someone has to file a 1040 to ask for it.
This is where money quietly disappears. A teen earning $8,000 with no exempt claim might have $500 or more withheld over the year. If they never file, that money sits with the Treasury. They have three years from the original filing deadline to claim a refund, and after that it’s gone. Filing a simple return takes about 20 minutes using the IRS Free File program, and for a teenager it’s worth the time.
