The Major difference between IRS Form W-2 and W-4 is that when an employee starts a new job, they are eligible to file the Form W-4 to decide how much tax to withhold from an employee’s paycheck. On the other hand, an employee can file the Form W-2 every end of the year that indicates how much an employer paid and how much tax is withheld during the year.

When setting up a business, some factors should be considered to nail the industry, be it service-based or product-based. Out of which, tax liabilities remain the point of focus. Studies show that systematic analysis of the total tax liabilities helps organizations make better business decisions. It is possible through various courses of action, such as payroll tax forms.

Internal Revenue Service (IRS) requires every employer and employee to fill out payroll tax forms known as Form W2 and Form W4, respectively. Users have noticed a major difference between w-2 and w-4 tax forms. These forms are positioned significantly in the business hierarchy and categorized as payroll tax forms. However, there are a few differences between them. This blog aims to inform you about payroll tax forms W-2 vs. W-4 and their multiple uses. Let us have a concentrated look at the following sections!

What is a W-2 Form

Form W-2, also known as IRS Form W-2 Wage and Tax Statement, is a year-end tax document for which employers are held responsible. In other words, Form W-2 is a tax form that employers or business owners must provide to the Internal Revenue Service (IRS) and each employee at the end of the tax year. Form W-2 expresses the annual wages of employees, which helps in sorting out the monetary calculations. It points out the exact amount of gross earnings of the employees, total tax proportion out of their income, deductions, savings, medical care earnings, etc.

W-2 Form

Form W-2 displays the earned wages of employees to the IRS. Employers are supposed to provide it by the end of January or early February for employees to fill it out. Likewise, after filling in their details, they become W-2 Employees. It means that employers give them their income after deducting the tax amount. Employers keep an informational record of the payroll forms. Later, they even share it with the government as well. Pieces of information available in the W-2 are useful during income tax filing when the employees retire.

Generally, employers make numerous copies of W-2, but they should necessarily make six copies for the following use:  

  • Copy A- This copy is for the Social Security Administration (SSA).
  • Copy B- This copy is for those employees who have their federal tax returns
  • Copy-C- This copy of the W-2 takes care of the employee’s records.
  • Copy D- This copy of the W-2 takes care of the employer’s records.
  • Copy 1- This copy of the W-2 is for states, cities, or local tax departments.
  • Copy-2- This copy of the W-2 needs to be filled by employees. It should include their state, city, or local tax returns.

What is a W-4 Form

Form W-4 or Employee’s Withholding Certificate, is an Internal Revenue Service (IRS) form. Employees who work in an organization fill out the W-4 to let their employers know how much tax to withhold from their income or paycheck. Employees should fill it out correctly because incorrections lead to unnecessary taxes during the return file.

Form W-4

Every new employee joining a particular organization must fill out the W-4.  The entire system got revised in 2020, which simplified W-4. Filling out the Withholding Form does not necessarily restrict an employee’s tax to the filled amount. The information is subject to change and employees can change it whenever they want. However, IRS subjects W-4 form as a necessary document. Moreover, employees fill W-4 , whether new or old. 

The structure of the W-4 follows five sections in total. However, section numbers One and Five implies on employees. Moreover, filling out the remaining part helps the employer determine the exact amount to be withheld from the employee’s yearly income.

Some mandatory details includes:

  • Name 
  • Address
  • Social Security Number
  • Work Information
  • The Status Of Filing
  • Total Number Of Dependents 
  • Signature 

W-2 vs W-4: What’s the Difference

The features of both forms, W-2 and W-4, are not entirely homogeneous. Both are for business purposes, but the person filling them out marks a difference. Understanding the differences may be difficult because of the apparent similarities.

The W-2 represents the employers of organizations. Furthermore, employees fill the form every year. Through W-2, employers track their employees’ income, including everything from their total income to savings. W-4, on the other hand, is an area of focus for the employees. It records an amount (variable as it is subject to change) that must be withheld as taxes. 

One question that comes to all of our curious minds is “is w4 the same as w2″ ? If put compactly, W-2 determines how much employees should be taxed on their yearly paycheck or income, and W-4 marks the total amount of money employees make every year by working in an organization.

How Do The Forms W-2 And W-4 Work

Form W-2

The Internal Revenue Service requires eligible employers to send W-2 forms to their employees before Jan 31st, following the close of the tax year.  Employers must submit these forms with the SSA (Social Security Administration) and the IRS by the end of January, however, may file for a 30-day extension by filing Form 8809.

Also, even if the employer requests and gets an extension to submit the W-2 form with the SSA and IRS, they still need to submit the employee’s copies of their W-2 forms by the 31st of January unless they also drop a request for an extension post the due date.

The W-2 consists of several compartments or boxes on the page’s left and right sides These sections represent various things such as the total amount of taxes, total income, medical aid taxes, tips, and more.
