You're exempt from federal income tax withholding only if both are true: you owed no federal income tax last year, and you expect to owe none this year. If you qualify, your employer takes zero federal income tax out of your checks — but Social Security and Medicare (FICA) still come out. Most working adults do *not* qualify; exemption is mainly for students, part-timers, and low earners whose income falls under the standard deduction.
To claim exempt on your W-4, you must meet both conditions. Failing either one means you can't legally claim it:
There's no checkbox. On the 2026 Form W-4, complete Step 1 (name, address, SSN, filing status), then write the word "Exempt" in the space below Step 4(c), skip Steps 2–4, and sign Step 5. An exemption only lasts one year — you must file a new W-4 by February 15 each year to keep it.
| Tax | Withheld if exempt? |
|---|---|
| Federal income tax | No — $0 withheld |
| Social Security (6.2%) | Yes — still withheld |
| Medicare (1.45%) | Yes — still withheld |
| State income tax | Separate — depends on your state's form |
Exemption only stops federal income tax withholding. FICA is mandatory and keeps coming out, and state withholding follows your state's own rules.
If you claim exempt but end up owing tax, nothing was set aside — so you'll face a lump-sum bill at filing, plus a possible underpayment penalty. If you're not sure, it's safer to let normal withholding happen and get a refund. Check what *should* be coming out with the paycheck calculator.
You're exempt only if you owed no federal income tax last year and expect to owe none this year — typically students, part-time workers, and low earners whose income is below the standard deduction. Most full-time workers don't qualify.
No. Exemption only stops federal income tax withholding. Social Security (6.2%) and Medicare (1.45%) are mandatory and still come out of every paycheck.
Fill out Step 1 with your personal info and filing status, write 'Exempt' in the space below Step 4(c), skip Steps 2–4, and sign Step 5. You must submit a new W-4 by February 15 each year to keep the exemption.
You'll owe the full amount as a lump sum at tax time, plus a possible IRS underpayment penalty for not paying enough during the year. If you're unsure whether you qualify, it's safer not to claim exempt.
