W-4 form: How to fill it out in 2024-2025

When you start a new job, you’ll be required to submit a W-4 form, also known as the Employee’s Withholding Certificate. The W-4 is a crucial tax document, because it tells your employer how much in federal taxes to withhold from your paycheck.

That, in turn, determines whether you’ll get a refund or owe money when you file your tax return. (The W-4 form is generally for employees, not independent contractors or gig workers, who must make estimated tax payments.)

How to file a W-4 form in five steps

You can do all five steps below to fill in your W-4, but only Steps 1 and 5 are required by the IRS. Steps 2 to 4 are optional — only do them if they apply to your situation.

Step 1: Enter your personal information

The first step is to fill out your name, address and Social Security number in sections 1(a) and 1(b).

Make sure your name is as it appears on your Social Security card —if it’s different, the IRS says you’ll need to contact the Social Security Administration to ensure you receive credit for your earnings.

For your tax filing status, check one of the three boxes in section 1(c).

• Single or married filing separately.
• Married filing jointly or qualifying surviving spouse.
• Head of household (for single taxpayers who pay more than half the cost of keeping up a home for themselves and a qualifying person).

Step 2: Multiple jobs or spouse works

The second step applies only if you’re holding down two jobs at once or if you’re married filing jointly and you and your spouse both work. If one of these scenarios applies to you, then you have three options:

• Use the IRS tax withholding estimator, which is the most accurate way to calculate how much you should have withheld. Once you complete the process, the tool lets you download a W-4 (and one for your spouse, if married) with the withholding information filled out correctly.
• Use the multiple jobs worksheet on page 3 of the W-4 form. After filling out the worksheet, enter the amount on line 4(c) on your W-4.
• If you and/or your spouse work a total of only two jobs, simply check the box at the end of line 2(c) on the W-4 (you must also check the same box on the W-4 for the other job). By checking the box, your standard deduction and tax brackets will be cut in half for each job to calculate withholding. This option is somewhat accurate for jobs with similar pay; if one job pays more than the other job, more tax than necessary may be withheld, and this extra amount will be larger the greater the difference in pay between the two jobs, according to the IRS.

Step 3: Claim dependents

The third step is for figuring out how much of the child tax credit (and credit for other dependents) you might be able to claim. The IRS has a tool to help you determine who you can claim as a dependent.

If you have dependent children under age 17, multiply the number of children by $2,000. If, for example, you have three children under 17, enter $6,000 on the first blank line. If you have other qualified dependents, you can multiply the number of them by $500 and enter this amount in the second blank line of this section. Add these two figures together and enter the sum on line 3.

Step 4: Factor in additional income and deductions

The fourth step is for other adjustments you might want to make. This step has three parts.

• Other income (not from jobs): You can include other income you receive not related to jobs, such as interest, dividends and retirement income. Enter the total on line 4(a).
• Deductions: If you plan to claim itemized deductions (rather than the standard deduction) to lower your tax liability, fill out the worksheet on the bottom of page 3 and enter the result on line 4(b).
• Extra withholding: You can withhold additional tax from your paychecks for each pay period, including any amounts from the multiple jobs worksheet. You can designate a specific amount for withholding, like an extra $50 from your paychecks, on line 4(c).

Step 5: Sign and file with your employer

Once you’ve reviewed your form and verified that the data you provided is correct, sign and date it and return it to your employer.

What to keep in mind when completing your W-4

You can change information on your W-4 as needed. If you start a second job, for example, consider filling out a W-4 for the new job and submitting an updated W-4 to your existing employer, checking the box on line 2(c) on both forms.

If your life situation changes, that’s another good reason to submit an updated W-4 to your employer. For example, perhaps you became the sole caregiver for a dependent child and now qualify for head of household status. That could entitle you to a higher standard deduction, resulting in lower tax liability compared with a single filer status. Changing the status on your W-4 could mean more money for you in each paycheck, rather than waiting till tax time to get your money back as a refund.

Claiming an exemption from withholding

If you had no tax liability in the previous year and don’t expect to owe any taxes this year, you may be able to claim exempt status on your W-4. Doing so tells your employer to refrain from withholding any of your pay for federal taxes. See page 2 of the W-4 form for more information. If you choose this option, you’ll have to fill out a W-4 form each year by Feb. 15 (or by the first business day after if the 15th falls on a weekend or holiday) to maintain your exempt status.

FAQs about filling out Form W-4

Here are some frequently asked questions about filling out the W-4 form.

What should you put on your W-4?

What you put on your W-4 comes down to how much money you would like taken out of your paycheck to pay your taxes. If you want to be sure to have the correct amount withheld, and thus avoid a large tax bill and potential late-payment penalties and interest when you file your tax return, use the IRS’ tax withholding estimator to determine how much you should have withheld from each paycheck. Alternatively, if you have more than one job you can use the multiple jobs worksheet on page 3 of the W-4 form.

You can also enter extra withholdings on line 4(c), or decrease your number of dependents. Increasing your withholding — which is the amount your employer sends out of your paycheck to the IRS on your behalf — makes it more likely that you end up with a refund come tax time.

On the other hand, if you got a large refund last year and you’d rather have bigger paychecks each month instead of waiting until tax time to get your money back, you can use the W-4 to reduce how much is withheld from your paychecks. You can do this by reducing the amount of untaxed income that you entered on line 4(a), increasing the figure for itemized deductions in line 4(b), or reducing any “extra withholding” amount you entered on line 4(c).

Do you claim 0 or 1 on your W-4?

Up until 2020, the W-4 form required you to choose 0, 1 or more allowances. But the IRS updated the form in 2020, establishing a new, more accurate way for taxpayers to calculate their tax withholding.

What do you put on your W-4 if no taxes are taken out?

If you want to have zero taxes withheld from your paychecks, then you need to claim exempt status. To do that, you must have had no tax liability in the previous year and expect to have no tax liability for the current year. If you meet these qualifications, you can inform your employer not to withhold federal income tax from your paycheck by writing “exempt” below line 4(c). Read “exemption from withholding” on page 2 of the W-4 form for more information.

Your employer will still withhold Social Security and Medicare taxes regardless of your exempt status. Also, your exemption will only last for one year. You’ll have to file a new W-4 claiming you’re exempt from withholding by Feb. 15 of a given year in order to maintain that status.

How do you have more taxes taken out of your paycheck?

To have more taxes taken out of your paycheck, enter the extra amount you’d like withheld from each paycheck on line 4(c) of the W-4.

How do you have less tax taken out of your paycheck?

You can use the W-4 form to reduce how much is withheld from your paychecks. To do this, decrease any amount you have entered on line 4(c); same goes for “other income”on line 4(a). You can also submit a new W-4 if you have a new dependent, which will reduce your withholdings.
