You can claim exempt from federal income tax withholding only if you meet two conditions: you had no federal income tax liability last year, and you expect to have none this year. If both are true, your employer stops withholding federal income tax from your pay. If either isn't true, claiming exempt will almost certainly leave you with a tax bill.
Being exempt from withholding is narrower than many people think. It doesn't stop Social Security or Medicare, it doesn't automatically cover state tax, and it lasts only for one calendar year.
The two tests for being exempt from withholding
The W-4 instructions and IRS Publication 505 set out the rule:
- No liability last year. You owed no federal income tax for the prior year. Getting a refund isn't enough. Your total tax (the "total tax" line on your return) must have been zero, so that any refund was all of your withholding.
- No liability expected this year. You expect your total federal income tax for the current year to be zero as well.
People who commonly meet both tests include students and others with part-time or seasonal jobs whose total income stays below the standard deduction. For 2026, the standard deduction for a single filer is $16,100. Income above that doesn't automatically mean you owe tax, because credits can reduce it, but it makes zero liability much less likely.
A few situations can block exempt status even at low income, such as when someone else can claim you as a dependent and you have certain unearned income like interest or dividends. Publication 505 lists these limits.
What claiming exempt does and doesn't stop
| Paycheck item | Stopped by claiming exempt |
|---|---|
| Federal income tax withholding | Yes |
| Social Security (6.2%) | No |
| Medicare (1.45%) | No |
| State income tax | Not automatically; states use their own forms and rules |
| Local income tax | Not automatically |
Social Security and Medicare, together known as FICA, apply to nearly all wages regardless of your W-4. Our guide to what FICA tax is explains why.
Example: a part-time job where withholding is already zero
Consider a single worker in Ohio earning $15 an hour for 20 hours a week, paid weekly. That's about $15,600 for the year, below the $16,100 standard deduction. The PaycheckHubs paycheck calculator estimates this weekly paycheck:
| Weekly paycheck | Amount |
|---|---|
| Gross pay | $300.00 |
| Federal income tax (standard W-4) | $0.00 |
| Social Security | $18.60 |
| Medicare | $4.35 |
| Ohio income tax | $0.00 |
| Net pay | $277.05 |
With a standard W-4, federal withholding is already $0 here, because the withholding formula builds in the standard deduction. Claiming exempt wouldn't change this paycheck at all. The Ohio figure is an estimate; the calculator applies Ohio's 2026 schedule of 0% up to $26,050, and many Ohio cities also levy a municipal income tax. See the Ohio paycheck calculator for details.
That is a useful point for anyone tempted to claim exempt: if your income is truly low enough to owe nothing, standard withholding is often already at or near zero.
Example: when claiming exempt goes wrong
Now take a single worker in Ohio earning $19 an hour full time (40 hours a week), or about $39,520 a year. With a standard W-4, the calculator estimates federal income tax withholding of about $49 per week, or about $2,563 for the year.
If this person claimed exempt, that $2,563 would not be withheld. But because their income is well above the standard deduction, they would still owe roughly that amount when filing, all at once. Depending on the size of the balance, an underpayment penalty can be added as well. Claiming exempt doesn't reduce tax; it only moves the bill to April.
How to claim exempt on the W-4
- Fill in Step 1 (name, address, filing status) on Form W-4.
- Write "Exempt" in the space below Step 4(c).
- Leave Steps 2, 3 and 4 blank, and sign Step 5.
- Give the form to your employer.
Exempt status covers only the calendar year you claim it for. To stay exempt the next year, you need to give your employer a new W-4 claiming exempt by February 15. If you don't, your employer must start withholding federal income tax again, following the IRS rules in Publication 15.

Alternatives if you just want more take-home pay
If you don't meet both tests but want less withheld, claiming exempt is the wrong tool. Better options:
- Claim the credits you qualify for in Step 3, such as child-related credits.
- Report deductions beyond the standard deduction in Step 4(b).
- Use the IRS Tax Withholding Estimator to set withholding as close as possible to your actual tax.

Frequently Asked Questions
Does claiming exempt stop Social Security and Medicare?
No. Claiming exempt on a W-4 only stops federal income tax withholding. Social Security and Medicare are still taken from your wages.
Can I claim exempt for part of the year?
Exempt status applies from when your employer processes the W-4 until the end of that year. You can also submit a new W-4 to end it early if your situation changes.
What happens if I claim exempt and then owe tax?
You owe the full amount when you file, and you may owe an underpayment penalty. Knowingly claiming exempt when you don't qualify can also bring IRS penalties.
Am I exempt from state withholding too?
Not automatically. Each state has its own withholding form and rules, so check with your state tax agency.
