TL;DR
- ✅ Step 1: check “Single or Married filing separately”
- ✅ One job, no dependents: leave Steps 2, 3 and 4 blank
- ✅ Second job, kids, or other income: use the calculator below for Steps 2–4
- ✅ Step 5: sign and date, or the form is not valid
Line by line for a single filer
Step 1(a)–(b)
Name, address and Social Security number. The name must match your Social Security card.
Step 1(c)
Check “Single or Married filing separately.” This one box covers both statuses on the W-4.
Step 2
Skip unless you hold two jobs at once. If you do, see our guide on filling out a W-4 with two jobs.
Step 3
Skip unless you have a qualifying child or other dependent. Single parents should read the head of household section below first.
Step 4
Skip unless you have side income (4a), deductions beyond the standard deduction (4b), or want extra tax taken out (4c).
Step 5
Sign and date. Your employer keeps the form; it is not sent to the IRS.
The Single withholding tables already include the standard deduction, which is $16,100 for a single filer in 2026. That is why a single person with one job can usually leave the optional steps empty and still land close to the right amount.

- You have a second job or a gig. Each employer withholds as if its paycheck is your only income. Read how to fill out a W-4 with two jobs or how to handle side income.
- You have a qualifying child. Step 3 takes $2,200 per child under 17 and $500 per other dependent.
- You expect to itemize or claim the new deductions. Step 4(b) is where tips, overtime, car loan interest and senior deductions go. See how the 2025 tax law changes your 2026 W-4.
- You always owe in April. Add a flat amount per paycheck in Step 4(c). Our Step 4(c) guide shows how to size it.
Single or head of household?
Head of household has a larger standard deduction ($24,150 versus $16,100 for 2026) and lower withholding, but you only qualify if you are unmarried and pay more than half the cost of keeping up a home for a qualifying person who lived with you more than half the year. Living alone, or supporting a roommate, does not qualify. If you do qualify, see our head of household W-4 guide.
Can a single person claim exempt?
Only if you owed no federal income tax last year and expect to owe none this year. Working a full-time job almost always rules that out. Students and part-year workers sometimes qualify; see W-4 exempt: who can claim it. Exempt status expires every February 15 and must be renewed.
⚠️ Your filing status on the W-4 is not locked in
The W-4 only controls withholding. Your real filing status is chosen when you file your return. If you marry, divorce or gain a dependent, submit a new W-4; see how often you can change your W-4.
Frequently asked questions
What do I put on my W-4 if I am single?
Fill in Step 1 (name, address, Social Security number) and check the first filing status box, “Single or Married filing separately.” Sign Step 5. If you have one job and no dependents, you can leave Steps 2, 3 and 4 blank and your employer will withhold correctly for a single filer.
Do I check Single or Head of Household?
Check Head of Household only if you are unmarried and paid more than half the cost of keeping up a home for a qualifying person (usually your child) who lived with you for more than half the year. Single with no qualifying person is the correct box for most unmarried workers.
Should a single person fill out Step 2?
Only if you have more than one job at the same time, or your job is one of two. A single person with a single job leaves Step 2 blank.
Is the standard deduction built into single withholding?
Yes. The IRS withholding tables for the Single box already assume the standard deduction ($16,100 for 2026), so you only use Step 4(b) if you expect deductions beyond that, such as itemized deductions or the new tip and overtime deductions.
