What are the Differences Between W-2 vs. W-4 & How to Fill Them

The Internal Revenue Service (IRS) requires businesses to fill out the W-2 and W-4 forms. Both these tax forms serve different purposes. For the W-2 form, an employer needs to fill out the form using the personnel data and payroll record. In contrast, the W-4 form is completed by the employees to provide their withholding information. As the names of these tax forms resemble a lot, many employers and employees remain confused about it. Therefore, this guide provides a detailed comparison of W-2 vs. W-4 and how to fill them with UPDF.

W-2 vs. W-4 – A Quick Overview

Before we dive deep into the differences between W-2 vs. W-4, it is important to clarify their basics.

What is W-2?

W-2 is a tax form that the employer fills in to mention employee earnings and tax withholdings to the Social Security Administration (SSA) and state government agencies. The tax form reflects the gross earnings of employees and all the deductions from income, such as Medicare or Social Security taxes, dependent care, etc.

What is W-2

The employer must fill out a W-2 tax form using personnel data and payroll records. Below are the key points to fill in a W-2 form:

  • The employee's Social Security number (SSN).
  • The employer's name, address, zip code, and employer identification number (EIN).
  • Wages
  • Tips
  • Withheld Social Security and federal income taxes
  • Withheld Medicare, state, and local income taxes
  • Employer-sponsored health coverage
  • Dependent care benefits
  • Allocated tips
  • Nonqualified plans
  • Deferred compensation

Employers are required to provide employees with a filled W-2 form no later than January 31 of the following year. The copies of the W-2 form are also submitted to the Social Security Administration (SSA) and state and local authorities.

What is W-4?

W-4 is the employee's withholding certificate that helps the employer withhold the correct federal income tax from the employee's paycheck. The key points to fill in a W-4 form include:

  • Name, address, and marital status of the employee
  • Multiple jobs or spouse works
  • Claim dependents
  • Withholding adjustments
  • Employee signature
What is W-4

The employees are usually asked to fill out the W-4 form at the time of their hiring so that the employer can adjust the payroll accordingly. However, employees can make changes to the W-4 form at any time.

W-2 vs. W-4 – 5 Key Differences

The above overview of W-2 and W-4 tax forms reflects that they are a lot different from each other and come with different purposes. So, below are the five key W-2 vs. W-4 differences worth knowing:

1. Purpose

The purpose of the W-2 form is to get the employees' earnings and tax withholding information. In contrast, the purpose of the W-4 form is to create an employee's withholding certificate so that the employer withholds the required tax.

2. Information Filled

The W-2 form contains multiple boxes that require the employee to fill in proper details about the employee's complete earnings. This includes salary, tips, compensation, etc. Besides that, the W-2 form also requires proper details on taxes withheld, Medicare and Social Security contributions, etc.

The W-4 form contains a few boxes and mostly asks for information related to the employee's tax withholding preferences. It requires the employees to add the number of allowances, filing status, and other withholding they want. So, there is no information about the earnings or tax deductions.

3. Filled By

The employer fills out the W-2 form, and copies are sent to the employee, Social Security Administration, and state/local agencies. In contrast, employees fill out the W-4 form during the onboarding day or before the first salary.

4. Submission Time

The W-2 form should be provided to employees no later than January 31 of the following year. On the other hand, the W-4 form is not submitted to any external entity. It should be filled and given to the employer before the employees receive their first salary.

5. Submission Frequency

The employer fills out the W-2 form once per year for each employee. In contrast, employees first fill out the W-4 forms on the first day of the job. Afterward, employees fill out the W-4 form again when they face any personal or financial changes.
