What Should a 17-Year-Old Claim on a W-4: Exempt Test and Refunds

A 17-year-old with a typical part-time job should claim exempt on a W-4 if they expect to earn less than $16,100 in 2026 and owed no federal income tax last year. Claiming exempt stops federal income tax from being taken out of each paycheck. If your earnings will run higher than that, or you had a tax bill last year, fill out the W-4 as a single filer and leave the exempt box unchecked.

The Two-Part Test for Claiming Exempt

Federal law lets you claim exempt from income tax withholding only if two things are true: you owed no federal income tax for the prior year, and you expect to owe none for the current year.¹ For most 17-year-olds in a first or second year of part-time work, both are usually easy to meet.

Whether you’ll owe federal income tax in 2026 comes down to whether your total income exceeds your standard deduction. Because most 17-year-olds are claimed as dependents on a parent’s return, a special formula applies: your standard deduction equals your earned income plus $450, with a floor of $1,350 and a ceiling of $16,100 (the regular single-filer amount for 2026).² So if your only income is from a job and you expect to earn less than $16,100 for the whole year, your deduction wipes out all your taxable income. Zero tax liability, and you qualify for exempt.

Once your annual wages get close to or above $16,100, the deduction stops covering everything, and you’ll owe federal tax on the rest. At that point, claiming exempt would be wrong.

How to Fill Out the 2026 W-4

Get the current form from the IRS website or your employer’s onboarding paperwork.³ The path through the form depends on whether you’re claiming exempt.

If You Qualify for Exempt

Fill in only these parts and leave everything else blank:⁴

Step 1: your name (matching your Social Security card), address, and Social Security number. Check “Single” for filing status.
The exempt box, located below Step 4(c). Checking it certifies you had no tax liability last year and expect none this year.
Step 5: sign and date.

Skip Steps 2, 3, and 4. The IRS instructions specifically tell exempt filers to leave them blank.

If You Don’t Qualify for Exempt

Fill in Step 1 with your personal information and check “Single.” Most 17-year-olds can skip Step 2, which is for people working multiple jobs at the same time. In Step 3, you enter $0, because that step is for claiming dependents you support, and as a dependent yourself you don’t have any. Leave Step 4 blank unless you have income beyond your job or want extra tax withheld. Sign in Step 5.⁴

If you do hold two jobs at the same time, the simplest option is to check the box in Step 2(c) on the W-4 for both jobs. Then complete Steps 3 and 4 only on the W-4 for your higher-paying job, and leave those steps blank on the other. The IRS Tax Withholding Estimator at irs.gov/W4App can give you a more precise result.

When You Should Not Claim Exempt

Watch for these situations, because claiming exempt in any of them can leave you with an unexpected tax bill in April:

You expect job earnings above $16,100. Anything over the standard deduction gets taxed.²
You have unearned income. Interest, dividends, capital gains, and distributions from a custodial investment account all count. Unearned income above $1,350 can create a filing requirement for a dependent even when job earnings are low, and the combination of the two can push you past zero tax liability.⁵
You owed federal income tax last year. The rule looks at your actual tax liability, not the amount withheld from your paychecks. If your last return showed any tax owed before withholding was applied, you fail the prior-year test.

FICA Still Comes Out Either Way

Claiming exempt only stops federal income tax withholding. Social Security and Medicare taxes (together called FICA) still come out of every paycheck. In 2026 the combined employee rate is 7.65%, split into 6.2% for Social Security on earnings up to $184,500 and 1.45% for Medicare on all earnings.⁶ On a $500 paycheck, about $38.25 goes to FICA no matter what your W-4 says. A regular employee cannot opt out.

Side Income Isn’t Covered by the W-4

The W-4 governs only traditional employment where an employer runs payroll and withholds taxes. Money from freelancing, reselling online, tutoring, lawn care, or gig apps like DoorDash is self-employment income, and the W-4 has no effect on it.

Net self-employment earnings of $400 or more in a year require you to file a federal return and pay self-employment tax, even if you owe no regular income tax.⁷ Self-employment tax runs 15.3% and covers your Social Security and Medicare contributions, because there’s no employer paying the other half. You report the income on Schedule C and calculate the tax on Schedule SE.

Renewing an Exempt W-4 Each Year

An exempt W-4 lasts only through the calendar year you file it. To keep the exemption for the following year, submit a new Form W-4 claiming exempt by February 15. If that date falls on a weekend or legal holiday, the deadline moves to the next business day.⁸ Miss the deadline and your employer will start withholding as if you’re a single filer with no adjustments, which usually means more comes out than needed.

Update your W-4 mid-year too if your situation changes: a second job that pushes total income above $16,100, meaningful investment income, or starting a side business are all reasons to submit a fresh form.

Getting a Refund If Tax Was Withheld

If you didn’t claim exempt, or your employer withheld federal income tax from early paychecks before processing your W-4, you get that money back by filing a federal return. The IRS recommends filing to claim a refund even when your income is low enough that filing isn’t required.⁹ If your total earnings stayed under $16,100 and you had no other income, your refund equals the full amount of federal income tax withheld.

You’ll need Form 1040 and the W-2 your employer sends in January. IRS Free File offers free preparation software aimed at straightforward returns, which fits most teenagers.¹⁰ First-time filers enter $0 as prior-year adjusted gross income when the software asks for identity verification. Direct deposit is the fastest way to receive the refund.

The Penalty for a False Exempt Claim

Intentionally claiming exempt when you know you’ll owe taxes carries a $500 civil penalty on top of the taxes and interest owed.¹¹ The penalty applies when there was no reasonable basis for what you put on the form. A teenager who honestly expects to earn under $16,100 and had no prior-year tax liability has nothing to worry about; the penalty targets people who deliberately understate their withholding to inflate their take-home pay.

State Withholding Is a Separate Form

The federal W-4 controls only federal income tax withholding. If you live in a state with an income tax, your employer may ask you to complete a separate state form. Some states accept the federal W-4 for state purposes, others require their own version, and several states have no income tax and no state form. Your employer’s payroll or HR department can tell you which forms your state uses and whether a state-level exemption is available.
