Teen Summer Job Taxes: Claiming Exempt on the W-4

This article is general information, not tax or financial advice. Tax rules change, individual situations vary, and every figure here is an estimate. Confirm specifics with a qualified tax professional before making money decisions.

Can a teen claim exempt on the W-4? The two-part test

There is exactly one test, and it has two halves. Both have to be true.

You had no federal income tax liability in 2025, and you expect no federal income tax liability in 2026. Miss either half and you cannot check the box.

The first half is easier than it sounds. You satisfy it if the total tax on line 24 of your 2025 Form 1040 was zero (or less than the total of lines 27a, 28, 29, and 30), or if you were not required to file at all because your income was under the filing threshold. A first-time worker who has never filed a return clears the first half automatically.

So for a typical 16-year-old starting their first job, the whole decision comes down to the second half: will 2026 earnings stay small enough that no federal income tax is owed?

Be clear on one thing first. The exempt box is a certification you sign under penalties of perjury. It states what you expect to owe, and it is on you if that expectation turns out wrong.

The 2026 math: how much can you earn before you owe federal income tax?

Most articles flatten this to “under $16,100 you owe nothing.” That happens to be right for a wage-only teen, but it hides the rule, and the rule matters the moment anything else is going on.

For 2026, a person who can be claimed as a dependent gets a standard deduction equal to the greater of $1,350 or earned income plus $450, capped at the single standard deduction of $16,100. Earned income means wages, salary, and tips. The formula grows with the paycheck until it hits the ceiling.

Run it against a few realistic summers:

Wages for the year	2026 dependent standard deduction	Federal income tax owed
$3,000	$3,450	$0
$6,000	$6,450	$0
$12,000	$12,450	$0
$16,100	$16,100 (capped)	$0
$18,000	$16,100 (capped)	tax on $1,900

The deduction always stays $450 ahead of the wages until the cap catches it. That is why a wage-only teen owes nothing until earnings pass $16,100, and why the first dollar of tax lands in the 10% bracket, which runs from $0 to $12,400 of taxable income for a single filer in 2026.

The unearned income blocker nobody mentions

Almost no consumer article covers this next rule, and it disqualifies more teens than you would guess.

A dependent cannot claim exempt if total income for the year will be more than $1,350 and includes more than $450 of unearned income. Unearned income means interest, dividends, and distributions from a custodial account, not wages.

Read that again if there is a UTMA account, a savings account with a real balance, or grandparent-funded index funds in the picture. A teen earning $4,000 at a summer job would clear the wage test easily, but $600 of dividends in a custodial account puts them over the $450 unearned line with total income well past $1,350, and the exempt box is off the table. Comfortable wage math does not save it.

Exempt does not mean tax-free: what still comes out of the check

This is where the first pay stub causes an argument at the kitchen table.

Claiming exempt switches off federal income tax withholding only. It does nothing to anything else on the stub. Social Security at 6.2% and Medicare at 1.45%, 7.65% combined, come out of every paycheck no matter your age, your income level, or your exempt status. There is no minimum. FICA applies from the first dollar.

Work a $3,000 summer with the exempt box checked and the federal income tax line reads $0, but $229.50 is still gone: $186.00 to Social Security and $43.50 to Medicare. At $6,000 it is $459.00. A teen will never come near the $184,500 Social Security wage base, so the 6.2% applies to everything they earn.

State tax is a separate story too. In most states, state withholding is its own election on its own form, with its own exemption rules and its own thresholds, so the federal exempt box does not carry over. A few states do run state withholding off the federal Form W-4, so check what your state expects rather than assuming. Some states also run payroll taxes that hit the check regardless: California SDI, New York PFL, and similar programs elsewhere.

If the size of that first check is the actual question, our breakdown of gross versus net pay walks the whole stub line by line, and why your first paycheck is smaller than you expected covers the timing quirks that make check number one the worst one of the year.

How to claim exempt on the 2026 W-4 (the form changed)

Nearly every guide online still describes the old method, so read this part carefully.

Through the 2025 form, you claimed exemption by writing the word “Exempt” in the space below Step 4(c). Some articles get it even more wrong and tell you to use “line 4c,” which does not exist. Step 4(c) is the extra-withholding line.

On the 2026 Form W-4, there is a dedicated “Exempt from withholding” section between Step 4 and Step 5, with a certification checkbox. Four steps:

1. Complete Step 1(a): name and address.
2. Complete Step 1(b): Social Security number.
3. Check the box in the Exempt from withholding section, certifying that both conditions are met.
4. Complete Step 5: sign and date.

Then stop. Do not complete any other step. No Step 2 multiple-jobs entries, no Step 3 dependents, no Step 4 adjustments. The IRS instruction is explicit about that, and a stray entry elsewhere on the form muddies what the employer’s payroll system does with it.

Two more mechanics worth knowing:

Exempt expires. A 2026 claim covers 2026 only. To stay exempt into 2027, a new Form W-4 has to reach the employer by February 16, 2027. (The general rule people quote is February 15, but the 2026 form specifies the 16th, since the 15th is Washington’s Birthday.) If nothing arrives, the employer must withhold as single or married filing separately with no other entries in Steps 2, 3, or 4, which is the highest-withholding default.

A late form is not retroactive. If you turn in an exempt W-4 three weeks into the job, the employer applies it going forward. They will not refund federal income tax already withheld. That money comes back only when you file a return.

When exempt is the wrong move, and what to do instead

Exempt is a good fit for a genuinely small summer of work. It is the wrong call in several situations that come up constantly:

• A big year. Full-time summer hours plus a school-year job can clear $16,100 faster than anyone plans for. At $18,000 the standard deduction caps out and $1,900 is taxable, which is $190 of federal income tax at the 10% rate. Nothing was withheld to cover it.
• Unearned income. Any custodial account throwing off more than $450 disqualifies the claim outright, as covered above.
• A second job. Two employers each withholding as if they are your only employer is already a withholding problem. Adding exempt to one of them makes it worse. Our post on W-4 withholding with two jobs covers the fix.
• Honest uncertainty. If nobody knows how many hours the fall will bring, do not certify a prediction under penalty of perjury.

The most common complaint has a specific fix. Picture a teen working ten weeks and watching withholding come out as though those wages will continue all year. Payroll annualizes. Ten weeks at $600 looks to the system like a $31,200 salary, so it withholds accordingly, even though the actual year total is $6,000 and the actual tax is zero.

The correct tool there is the part-year withholding method, not the exempt box. Two things qualify you: you use the calendar year as your tax year, and you expect to be employed no more than 245 days during the year. Then you have to ask in writing. Pub. 505 says the request must state the date of your last day of work for any prior employer during the current calendar year, that you do not expect to be employed more than 245 days this year, and that you use the calendar year as your tax year. The employer has to agree, and plenty of payroll departments will not do it, but it is worth asking.

If neither route fits, the fallback is fine: claim nothing, let too much come out, and get it back by filing. Over-withholding is fully recoverable. A wrong exempt claim is not as easy to unwind.

Filing, refunds, and the situations with their own rules

Filing. A dependent with wages only generally has to file when earned income tops $16,100 for 2026. Below that, filing is optional, but file anyway if a single dollar of federal income tax was withheld, because the return is the only way to get it back. Refund-only returns cost nothing through IRS Free File.

Kiddie tax. It applies to unearned income and nothing else. The 2026 base amount is $1,350, so unearned income above $2,700 can be taxed at the parent’s rate on Form 8615. Summer wages are never kiddie-taxed, no matter how big the summer was.

Side money. Babysitting, mowing, dog walking, and reselling are self-employment, not wages. Net earnings of $400 or more trigger self-employment tax at 15.3% on 92.35% of net, and no exempt box touches it. Nothing is withheld along the way either, so this one shows up as a bill. Our guide on setting money aside for side hustle taxes has the mechanics.

Household employees under 18. Cash wages paid to a household worker who is under 18 at any point in the year are exempt from Social Security and Medicare, unless household work is that person’s principal occupation. For a student, it is not. The 2026 household-employee FICA threshold is $3,000 in cash wages.

Campus jobs. The student FICA exception under section 3121(b)(10) can exempt a student from Social Security and Medicare on wages from the school they attend. A half-time enrollment safe harbor applies, and professional employees are excluded.

Working for a parent’s business. Wages paid to a child under 18 by a parent’s sole proprietorship, or by a partnership in which both partners are the child’s parents, are not subject to Social Security and Medicare. Under 21, they are not subject to FUTA. If the business is a corporation, none of that applies and every tax comes out normally. Income tax withholding applies regardless of age.

Dependency. What the teen puts on their W-4 has zero effect on whether a parent can still claim them. That turns on the qualifying child rules: age, residency, and whether the child provided more than half of their own support.

Model the check both ways before signing anything

Settle it by putting the two paychecks side by side instead of arguing about them.

Salary Calculator from Stub44 has a per-profile federal exemption toggle along with the full W-4 inputs and withholding for all 50 states plus DC. Enter the summer wage, run it once with federal withholding on and once with the exemption toggled, and the real gap between the two stubs is right there. In most teen scenarios the gap is smaller than expected, because FICA and state tax do not move.

Saved profiles are useful here too: keep “summer job” and “school-year job” as separate profiles, add them up, and you can see whether the combined year is heading anywhere near $16,100 before anyone signs a form. If you want to sanity check an hourly offer first, the salary to hourly after taxes tool converts a rate into real take-home, and the W-4 withholding planner shows how each step of the form moves the check. Our deeper walkthrough of how the W-4 changes your take-home pay covers the rest of the form.

Frequently Asked Questions

Can my teenager claim exempt on their W-4?

Only if both conditions are true: they had no federal income tax liability in 2025 and they expect none in 2026. A teen who has never worked and was never required to file automatically satisfies the first condition, so the decision usually turns on whether 2026 earnings will stay under the dependent standard deduction.

How much can a teen earn before owing federal income tax in 2026?

For a dependent, the standard deduction is the greater of $1,350 or earned income plus $450, capped at $16,100. In practice a teen with only W-2 wages owes no federal income tax until earnings pass $16,100 for the year.

Does claiming exempt stop Social Security and Medicare from being withheld?

No. Exempt only turns off federal income tax withholding. Social Security at 6.2% and Medicare at 1.45%, or 7.65% combined, come out of every paycheck regardless of age, income, or exempt status. State income tax and state payroll taxes are separate and also unaffected.

Where do you write Exempt on the 2026 W-4?

You do not write it anymore. The 2026 Form W-4 has a dedicated Exempt from withholding section between Step 4 and Step 5 with a certification checkbox. Check the box, complete Steps 1(a), 1(b), and 5, and skip every other step. Older guides that tell you to write the word below Step 4(c) describe the 2025 form.

When does an exempt W-4 expire?

A claim of exemption is good only for the calendar year it covers. To stay exempt for 2027, a new Form W-4 has to reach the employer by February 16, 2027. Without one, the employer withholds as single or married filing separately with no other entries in Steps 2, 3, or 4.

Does my teen have to file a tax return for a summer job?

Generally only if earned income tops $16,100 for 2026. Below that, filing is optional, but they should file anyway if any federal income tax was withheld, because a return is the only way to get that money back. Refund-only returns are free through IRS Free File.

Does the kiddie tax apply to summer job wages?

No. The kiddie tax applies only to unearned income such as interest, dividends, and capital gains. For 2026 the base amount is $1,350, so unearned income above $2,700 can be taxed at the parent's rate on Form 8615. Wages from a job are never subject to it.

Do teens pay tax on babysitting or lawn mowing money?

Yes, if it adds up. Net self-employment earnings of $400 or more trigger self-employment tax at 15.3% on 92.35% of net earnings, and no W-4 exempt box protects against it. Nobody withholds from that income, so the tax shows up as a balance due at filing time.
