What is the Difference Between W2 vs W4

w2 vs w4

Generally, the difference between IRS forms W2 and W4 only lies in the fact that different entities fill them out. Though the main purpose is about the taxes to be withheld, form W 4 is needed to be filled out by employees on their new job in order for employers to know how much tax should be withheld on the employee’s paycheck. On the other hand, employers need to file form W 2 at the end of each year to indicate how much tax was withheld.

W 2 vs W 4 Difference

Who Fills Each Out

Form W 4 – A W 4 form is a requirement and is needed to be filled out by an employee that is new to the job. In 2020, the Internal Revenue Service made changes to Tax Form W 4 to increase transparency and accuracy of the payroll system.

On a good note, there’s no reason for employees fill out new forms if they haven’t changed jobs.

Form W 2 – On the other hand, a W 2 form is filled out by employers.

Purpose

Form W 4 – W 4 forms, or the Employee’s Withholding Allowance Certificate, are needed by the employers to know how much income taxes should be withheld from each employee’s paychecks. A complete W 4 form tells your employer the correct amount of federal income tax to be withheld from one’s pay.

The income tax calculation would depend based on one’s current financial situation such as marital status, personal withholding preferences, and the number of dependents. Thus, it is advisable for an employee to complete W 4 forms every year or whenever one’s financial status changes.

Failure to submit a Form W 4, or even having incorrect information, would lead to having you either paying too much or less tax.

Form W 2 – A Form W 2, or the Wage and Tax statement, is one of the IRS tax forms that serve as a year end tax document on an employee’s earnings for the whole year. This would include an employee’s gross pay, annual wages, social security and Medicare taxes, and the amount of taxes withheld from their paychecks.

Apart from having this information submitted to the government, the employer is also required to send this document to both the IRS and their respective employees.

When to Fill Out and Submit

Form W 4 – W 4 forms should be filled out by an employee upon starting a new job. On a special note, as what has been stated above, employees are advised to fill out and submit new W 4 forms whenever their financial situations change.

Form W 2 – W 2 forms are legally required to be sent out to the employees on or before the deadline on the 31st of January. This would give employees enough time to file their income taxes for the tax year, which usually falls on the 15th of April.

Meanwhile, if the 31st of January falls on a legal holiday, or on a Saturday or Sunday, then the deadline is moved to the next business day.

Understanding the Forms

Form W 4

  1. The 1st step of filling out a W 4 form requires your typical personal information (full name, employee’s social security number, address) and marital status. If married, it is important to take note of whether you’ll be filing jointly with your spouse or separately.
  2. The 2nd step is for employees with an additional source of income. E.g. work of spouse, freelance income, second job.
  3. Step 3 indicates the number of dependents you have (number of children, other dependents).
  4. Step 4 is optional wherein you can indicate other sources of income aside from your jobs. Good examples are passive income from investing in stocks or forex.
