What Should You Claim on Your W-4 Form? Dependents and Withholding

If you’re wondering what to claim on your W-4, the short answer is: enter the filing status, dependents, other income, and deductions that match what you’ll actually report on your tax return, so your employer withholds close to your real federal tax bill. One quick clarification before anything else. The form that controls your withholding is the W-4. The W-2 is the year-end wage statement your employer sends you in January for filing your return. People mix the two up constantly, but you never “claim” anything on a W-2. Everything below is about the W-4, and specifically the 2026 version, which added several new line items after the One, Big, Beautiful Bill.

Step 1: Your Filing Status

Your filing status sets the standard deduction and tax brackets your employer will use, so it drives every calculation that follows. The 2026 standard deductions are $16,100 for Single or Married Filing Separately, $32,200 for Married Filing Jointly, and $24,150 for Head of Household.¹

Single applies if you’re unmarried or legally separated under a divorce decree. Married Filing Jointly is for couples combining income on one return. Head of Household requires that you be unmarried at year’s end, pay more than half the cost of maintaining your home, and have a qualifying person, typically a child or dependent relative, living with you more than half the year. If your spouse died and you have a dependent child, you can file as a Qualifying Surviving Spouse for up to two years after the death, which gives you the same rates and standard deduction as Married Filing Jointly.²

Technically, Step 1 plus your signature is all the W-4 requires. Skip everything else and your employer withholds based purely on the standard deduction for your status with no other adjustments.³ For most people that’s not enough.

Step 2: Multiple Jobs or a Working Spouse

This is where most withholding errors happen. The standard deduction and tax brackets only get applied once across all your household’s income, but each employer calculates withholding as if their paycheck is your only one. Two jobs, two full standard deductions, not enough tax withheld. Step 2 fixes this, and you have three options:³

The IRS Tax Withholding Estimator at irs.gov/W4app (Step 2a). Most accurate. It asks about every income source and gives you the exact extra withholding to enter, plus a pre-filled W-4 you can hand your employer.
The Multiple Jobs Worksheet on page 3 of the W-4 (Step 2b). A paper approximation if you’d rather not use the online tool.
The checkbox in Step 2c. Simple option for exactly two jobs with roughly similar pay. Check the box on the W-4 for both jobs and each employer applies half the standard deduction and half the brackets.

With options 2a and 2b, the adjustment goes on the W-4 for one job only, usually the highest-paying one. With 2c, both employers get a W-4 with the box checked. If you have multiple income sources and skip this step entirely, expect to owe at tax time.

Step 3: Dependents and Credits

Step 3 reduces your withholding to reflect credits you’ll claim on your return. For 2026, enter $2,200 for each qualifying child under age 17.⁴ Add $500 for each other dependent, meaning a child 17 or older, a dependent parent, or another qualifying relative.⁵ Total the amounts and put the figure on line 3.

Both credits phase out above $200,000 in total income, or $400,000 for married filing jointly.⁶ If your income sits well above those limits, claiming credits here that you won’t actually receive at filing time will leave you under-withheld.

Update the form when your household changes. A new baby, a child turning 17, or a dependent parent moving in all shift what you should be claiming, and old numbers on file mean your paychecks won’t reflect your real tax picture until you file.

Step 4(a): Other Income

Use Step 4(a) for income that won’t have taxes automatically withheld: interest, dividends, retirement distributions, and similar sources.⁵ Enter the estimated annual total and your employer spreads additional withholding across your paychecks. Self-employment income doesn’t belong here; that gets handled through quarterly estimated tax payments.

Reporting outside income on your W-4 helps you avoid an underpayment. The IRS charges interest on underpayments at 7% per year, compounded daily.⁷

Step 4(b): Deductions Above the Standard

If your deductions will exceed the standard deduction for your filing status, report the difference on line 4(b) so your employer withholds less. This is where a lot of people leave money on the table by not filling it in. The 2026 W-4 worksheet includes new categories from the One, Big, Beautiful Bill:⁵

Qualified tips, up to $25,000, if your total income is under $150,000 ($300,000 filing jointly).⁸
Qualified overtime pay, up to $12,500 ($25,000 filing jointly) of the time-and-a-half portion, same income limits.⁸
Passenger vehicle loan interest, up to $10,000, if total income is under $100,000 ($200,000 filing jointly).
Senior bonus deduction, $6,000 per person age 65 or older ($12,000 if both spouses qualify).⁹

The worksheet also accounts for student loan interest, IRA contributions, educator expenses, and itemized deductions like mortgage interest, charitable contributions, and medical expenses above 7.5% of income. State and local taxes can now be deducted up to $40,400 ($20,200 if married filing separately), up from the $10,000 cap that applied from 2018 through 2024.⁵

Step 4(c): Extra Withholding or Exempt Status

Line 4(c) lets you add a flat dollar amount of extra withholding per paycheck. People use it as a buffer when their income is uneven or when they simply want to guarantee a refund. It’s also the alternative to working through the deductions worksheet.

Directly below Step 4(c) is where you write “Exempt” if you qualify. You can claim exempt only if you had zero federal income tax liability last year and expect zero this year.¹⁰ This mostly applies to low-income workers, students with limited earnings, and people whose credits fully wipe out their tax bill. Exempt status expires every year: you have to file a new W-4 claiming it by February 15 or your employer starts withholding as if you’re single with no adjustments.¹¹ Claiming exempt when you’ll actually owe tax leads to a bill at filing time, plus possible penalties.

Submitting and Updating the Form

Give the completed W-4 to payroll or upload it through your HR portal. Your employer keeps it on file; the IRS doesn’t get a copy. Once a revised form is submitted, your employer must apply it no later than the start of the first payroll period ending on or after 30 days from receipt.¹¹

You don’t need a new W-4 every year, but you should file one after any event that shifts your tax picture: marriage, divorce, a new child, a spouse starting or leaving work, buying a home, or a significant change in income. One hard deadline applies. If a change makes your current withholding too low, you have 10 days to give your employer a corrected W-4.¹² Changes that increase your withholding are optional, submit them whenever.

The IRS Tax Withholding Estimator is the fastest way to sanity-check the form. It walks you through your income, deductions, and credits, then generates a pre-filled W-4 you can print. The IRS recommends running it at least once a year and after any major life change.¹³

Penalties for Getting It Wrong

Honest estimation errors don’t trigger penalties. The problems start in two situations. If you put false information on your W-4 without a reasonable basis, the IRS can assess a $500 civil penalty per false statement, on top of any tax and interest owed.¹⁴

If the IRS decides your withholding has been consistently too low, they can send your employer a lock-in letter that overrides your W-4 and forces a specific rate. After a lock-in letter takes effect, your employer can’t reduce your withholding without IRS approval. You get 60 days’ notice before the rate kicks in, and during that window you can send a corrected W-4 and supporting documentation directly to the IRS.¹⁵

State Withholding Is a Separate Form

The W-4 only handles federal income tax. If your state has an income tax, you may need a state-specific certificate. Some states accept the federal W-4; others, including California, New York, and Illinois, require their own form. States without an income tax, like Texas and Florida, need no state withholding form at all. When you start a new job, ask HR whether you need to file a state form in addition to the federal W-4.
