What it means
Claiming exempt from withholding on Form W-4 tells your employer not to take any federal income tax out of your pay. It's meant for people who truly won't owe any federal income tax for the year, such as many students and part-time workers with low income. It doesn't stop Social Security and Medicare tax, which are still withheld: the IRS says the exemption "applies only to income tax, not to social security or Medicare tax."
The two conditions
For 2026 you can claim exemption only if both are true:
- You had no federal income tax liability in 2025, meaning you were entitled to a refund of everything withheld, and
- You expect no federal income tax liability in 2026, meaning you expect a refund of everything withheld.
"No liability" means your total tax was zero, not just that you got a refund. If you owed any tax last year, even if withholding covered it, you can't claim exempt.
Rough income guide for 2026
Publication 505 includes a flowchart. If no one can claim you as a dependent and you're under 65 and not blind, you can usually claim exemption if your 2026 total income will be no more than your standard deduction: $16,100 single, $24,150 head of household or $32,200 married filing jointly. If someone (like a parent) can claim you as a dependent, you qualify if your income is $1,350 or less; above that, only if you have no more than $450 of unearned income (like interest) and total income of $16,100 or less. People who are 65 or older, blind, itemizing or claiming credits need Publication 505's worksheets instead.
How to claim it on the 2026 W-4
Fill in Step 1 and check the box in the Exempt from withholding section just before Step 5, then sign.
It expires every year
An exempt W-4 is good for one calendar year only. To stay exempt in 2027, you have to give your employer a new form by February 16, 2027, the date printed on the 2026 W-4 (the usual February 15 deadline falls on a federal holiday that year). If you don't, your employer must start withholding as if you're single or married filing separately with no other entries, and it won't refund what's withheld before a late exempt form arrives.
The risks
- A tax bill in April. If your income turns out higher than expected, for example from a second job or a raise, you'll owe the whole year's tax when you file.
- Penalties. The W-4 warns that claiming exemption when you'll owe tax can mean an underpayment penalty, and the IRS can charge a $500 penalty for a W-4 that cuts withholding without a reasonable basis.
- A lock-in letter. If the IRS sees serious under-withholding, it can tell your employer to withhold at a set rate and ignore any new W-4 that would lower it.
Better options for most people
If you just want bigger paychecks, you don't need to claim exempt. Use the IRS Tax Withholding Estimator to fill in the W-4 so withholding matches what you'll actually owe. If you owed last time, see why you might owe taxes this year, and check your stub with paycheck tax codes explained.
