What is Form W-4?

The W-4 Form, also known as the "Employee's Withholding Certificate," is an important IRS tax document that employees need to fill out and give to their employers. This form helps employers figure out how much federal income tax to withhold from each employee's paycheck throughout the year.

In the past, employees could claim allowances on their W-4 to reduce the amount of tax withheld, meaning less money was taken from their wages. However, big changes came with the 2017 Tax Cuts and Jobs Act, which removed personal exemptions.

The updated W-4 Form, introduced in 2020, still asks for basic personal information but no longer includes allowances. Now, to lower their tax withholding, employees must claim dependents or use a deductions worksheet when they fill out the W-4 Form.

How to Fill out a W-4 Form?

Filling out a W-4 Form is essential for managing your tax withholding accurately. Here are the simple steps to fill out a Form W-4:

Step 1: Provide Your Personal Information

Begin by entering your name, address, Social Security number, and tax filing status. Your filing status determines your eligibility for certain tax credits and deductions, so choose carefully.

Step 2: Address Multiple Employment Situations

If you have more than one job or if your spouse works, it's crucial to adjust your withholdings accordingly. For your primary job, complete steps 2 through 4(b) on the W-4 Form. For other positions, you can leave these sections blank. If you and your spouse each hold two jobs with similar earnings, check box 2(c) on both W-4 Forms.

Step 3: Claim Dependents

If your income is below $200,000 (or $400,000 for joint filers), list your dependents. Multiply their number by the applicable credit amount to adjust your withholdings accordingly. You may choose not to claim them if you prefer higher withholdings to manage your tax bill better.

Step 4: Adjust Withholdings

You can indicate any extra amounts you want withheld or if you expect to claim specific deductions that exceed the standard deduction.

Step 5: Submit Your Form W-4

Finally, sign and date the W-4 Form and submit it to your employer’s payroll or HR department. Some companies may allow online submission through their payroll systems.

By following these steps, you can fill out the W-4 Form accurately, ensuring appropriate tax withholding throughout the year.

Common Payroll Deductions You Should Know About

Here are a few examples of deductions that can be taken from your paycheck:

• Employee contributions to an IRA, 401(k), or other retirement account
• Employee contributions to an HSA, FSA, or other savings account
• Employee payments to an employer-sponsored healthcare plan
• Employee payments to a taxable group-term life insurance policy.

What is the Difference Between a W-2 and a W-4?

When starting a new job, you will likely encounter two forms: the W-4 and the W-2. While they might sound similar, they serve very different purposes.

W-4 Form: This form is essential when you start a new job. It provides your employer with information about your tax filing status and the number of allowances you claim. This information helps them determine the correct amount of federal income tax to withhold from your paycheck.

W-2 Form: This form is a year-end summary of your income and the taxes withheld from your paycheck. It's provided by your employer by January 31st of the following year. The W-2 is crucial when filing your annual tax return as it provides essential details like your gross earnings, federal, state, and local taxes withheld, and any other relevant tax information.

W-4 vs W-2: Key Differences

• Timing: W-4 is completed at the start of employment, while W-2 is received at the end of the year.
• Purpose: W-4 informs your employer about tax withholding, while W-2 provides a summary of your income and taxes withheld.
• Usage: W-4 is used by employees, while W-2 is used by both employees and the IRS.
