Filling out a W-4 for a 16-year-old usually comes down to three things: personal information at the top, a checkbox that claims exempt from federal income tax withholding, and a signature at the bottom. Most teens earn far less than the 2026 standard deduction of $16,100, so they owe no federal income tax and can skip the middle of the form entirely. The whole thing takes about five minutes.
What to Have Ready
Pull out the Social Security card first. The name on the W-4 has to match the card exactly, middle initial and all. A mismatch can cause the IRS to mispost wages, which turns into a headache at tax-filing time.1Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card If the name on the card is outdated, call the Social Security Administration at 800-772-1213 to get a corrected card before submitting the W-4.
You’ll also need the nine-digit Social Security number and a current home address. Employers pull the current form from the IRS website or hand you a version through their onboarding portal.2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate (2026)
Why a 16-Year-Old Usually Qualifies as Exempt
The W-4 lets you tell your employer to withhold zero federal income tax if two things are true: you owed no federal income tax last year, and you expect to owe none this year.2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate (2026) Most teens clear both tests easily.
A dependent’s 2026 standard deduction is the larger of $1,350 or earned income plus $450, capped at $16,100.3Internal Revenue Service. Rev. Proc. 2025-32, 26 CFR 601.602 Tax Forms and Instructions That deduction wipes out taxable income for almost any part-time job. A teen working 20 hours a week at $12 an hour earns roughly $12,480 over a year, and gets a standard deduction of $12,930. No taxable income, no tax owed.
The same math worked in 2025, when the single-filer standard deduction was $15,000. If last year was a first year with no job, the prior-year test is met by default.
One thing to watch: unearned income. Investment income, interest, or trust distributions above $1,350 can trigger a tax bill even when wages are low. If parents hold investments in a teen’s name that throw off more than a little interest or dividends, check whether claiming exempt still fits before checking the box.
Filling In the 2026 W-4
Step 1: Personal Information
Print the first name, middle initial, and last name in box 1(a). Enter the home address, city, state, and ZIP below. Write the Social Security number in box 1(b). For box 1(c), check “Single or Married filing separately.” That’s the right box for a 16-year-old with no dependents.
The Exempt From Withholding Box
This is the part that matters. Below Step 4, the 2026 W-4 has a section labeled “Exempt from withholding.” Check that box to certify no federal income tax liability for 2025 and none expected for 2026.2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate (2026) After checking it, complete only Steps 1(a), 1(b), and 5. Skip Steps 2, 3, and 4.
Older guides tell teens to write the word “Exempt” on a line under Step 4(c). The current form replaced that with a dedicated checkbox, so look for the checkbox instead.
Step 5: Sign and Date
Sign the form and write the date. A 16-year-old signs their own W-4; a parent doesn’t sign for them. The signature certifies the information under penalty of perjury, which is aimed at people gaming the system, not at teens who genuinely qualify.
If Exempt Doesn’t Apply
If the teen owed tax last year, or expects earnings over $16,100 this year, leave the exempt box unchecked. Complete Step 1 and Step 5 only, leaving Steps 2 through 4 blank. The employer will withhold at the default rate for a single filer with no adjustments,2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate (2026) which for most teens lands close to the actual tax owed. Any small difference sorts itself out at filing.
Two Jobs at the Same Time
Each employer gets its own W-4. The question is whether combined earnings will cross the $16,100 line. If not, exempt still works on both forms.
If the combined total will exceed that amount, complete Step 2 on at least one W-4. The form offers three ways to handle it:5Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate (2026)
Whichever method you use, fill out Steps 3 and 4 only on the W-4 for the higher-paying job. Leave those blank on the other.
FICA Still Comes Out
Checking exempt stops federal income tax withholding. It does not stop FICA. Every paycheck will still show 6.2% for Social Security and 1.45% for Medicare, a combined 7.65%.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates On a $400 paycheck that’s about $30.60. Nothing on the W-4 changes this.
One narrow exception: wages a teen under 18 earns working for a parent’s sole proprietorship, or a partnership where both partners are the parents, are exempt from Social Security and Medicare.6Internal Revenue Service. Family Employees That exception doesn’t apply if the family business is incorporated.
Exempt Expires Every Year
A W-4 claiming exempt is only good for the calendar year it’s filed. Claim exempt in June 2026 and the exemption ends on December 31, 2026. A new W-4 has to be filed by February 15, 2027, or the employer will start withholding as if the teen were a single filer with no adjustments.7Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate A late replacement W-4 takes effect going forward, but taxes already withheld won’t be refunded by the employer. Set a January reminder.
Turning It In and Reading the First Paystub
Hand the completed form to a manager, HR contact, or whoever runs onboarding. Many employers now use a digital payroll system where the W-4 is completed electronically on day one. Either way, keep a copy.
New withholding usually takes one or two pay cycles to show up. On the first paystub, look at the federal income tax line. If exempt was claimed, that line should read zero. Social Security and Medicare will still be there, which is normal. If federal income tax is being withheld despite the exempt claim, flag it with payroll right away.
Make Sure It’s a W-4 and Not a W-9
A W-4 is for employees. If the hiring paperwork is a W-9 instead, the employer is treating the teen as an independent contractor. No taxes are withheld from a contractor’s pay, and the worker is responsible for income tax and the full 15.3% self-employment tax.8Internal Revenue Service. What People New to the Workforce Need to Know About Income Tax Withholding Some employers misclassify teen workers to skip payroll taxes. If the job involves scheduled shifts, a uniform, and a manager’s instructions, it’s almost certainly employment, and the correct form is a W-4.
State Withholding Is a Separate Form
The W-4 handles federal tax only. Most states with an income tax have their own withholding form. Rules vary: some states allow an exempt claim similar to the federal one, others don’t, and a handful of states have no income tax at all. Ask during onboarding which state forms are needed, and check whether the state offers its own low-income exemption. If the employer doesn’t raise it, ask, because skipping the state form doesn’t skip state tax; it just leaves you to settle it at filing.
