Form W-4: What It Is and How to File (2024)

What Is Form W-4: Employee's Withholding Certificate?

When you start a new job, you will complete Form W-4, which is also called an Employee's Withholding Certificate. This form determines how much tax your employer will withhold from your paycheck. The amount withheld is paid to the Internal Revenue Service (IRS) using your name and Social Security number. When you file your annual tax return, you will be credited with the tax amount paid from your paycheck throughout the year.

Key Takeaways

  • Employees fill out a W-4 form to inform employers how much tax to withhold from their paychecks.
  • The amount withheld is based on filing status, dependents, anticipated tax credits, and deductions.
  • If the form is filled out incorrectly, you may not pay enough income tax throughout the year.
  • Employees can change their withholding by submitting a new W-4 to their employer.
  • A new W-4 must be completed with each new employer.

Understanding Form W-4: Employee's Withholding Certificate

You need to complete a W-4 correctly because the IRS requires workers to pay taxes on their income throughout the year. If you fail to withhold enough tax, you could owe a large sum plus interest and penalties for underpaying your taxes to the IRS when you file your tax return.

If you withhold too much tax during the year, your monthly income will be reduced, and you won’t get your excess tax back until you file your tax return and receive a refund.

You fill out a new W-4 form if you start a new job or change the amount withheld from your pay.

How to Fill Out Form W-4

If you are single, have a spouse who does not work, do not have dependents, have income from one job, and do not claim tax credits or itemize deductions on your tax return, filling out a W-4 is easy. Just provide your name, address, Social Security number, and filing status, and your withholding will be computed based on your standard deduction and tax rates.

You can increase your withholding using Form W-4 if you hold more than one job, both you and your spouse work, or have income from other sources that are not subject to withholding.

You can also decrease your withholding if you are eligible for income tax credits such as the child tax credit or credit for other dependents, or you are eligible for deductions other than the basic standard deduction, such as itemized deductions, the deduction for IRA contributions, or the deduction for student loan interest.

If you don’t submit Form W-4, the IRS requires your employer to withhold your wages as though you were single without other adjustments.

Revising Form W-4

You may need to submit a revised W-4 if your situation changes, such as getting married or divorced, having a child, or picking up a second job. You can also submit a new W-4 form if you discover that you withheld too much or too little tax from the previous year.
