IRS tax forms, like a W-2 vs. W-4, differ in several ways, including who is responsible for filling out each form, what each form is used for, and how employees and employers are affected by the information filled out on each form. 

Forms W-2 and W-4 are both basic tax forms we’ll all probably come across at some point in our professional lives. So it’s best to familiarize yourself with these two forms now so you aren’t confused about the differences later. 

Form W-2: IRS Wage and Tax Statement

Form W-2, also called an IRS Wage and Tax Statement, is a tax document containing information about an employee’s job status, their earnings from a particular employer, and any deductions taken out of the employee’s pay for taxes, savings, retirement, or childcare.

Each year, employees will receive their Form W-2 reflecting their earnings of the previous year around January or February. For example, employees would receive their W-2s for the year 2023 in January or February of 2024. Then the next year, they will receive their W-2s for 2024 in January or February of 2025, and so on. 

Employers are only required to send out W-2s if an employee’s annual income exceeds $600 during the prior tax year, even if they no longer work for that employer at the time they file. The IRS also specifies that employers must fill out W-2s for all qualified employees, even if that employee is related to the employer.1 

Form W-4: An Employee’s Withholding Certificate 

If you’ve ever started a new job with an established business, company, or commercial chain, you’ve most likely filled out Form W-4 before. Form W-4, also referred to as an Employee’s Withholding Allowance Certificate, is a form employees complete once they have accepted an offer of employment from an employer. 

Based on the information provided on an employee’s W-4, employers know how much federal, state, and local taxes to deduct from their employee’s paycheck. Usually, employees must complete this form prior to receiving their first paycheck. 

Key Differences Between Form W-2 and Form W-4

While Form W-2 and Form W-4 both have to do with an employee’s wages, they have some core differences. Check out more info about those differences below. 

Who Fills Out the Form

Employees are responsible for completing Form W-4, while employers are the ones who fill out Form W-2. However, the information employees fill out on Form W-4 will influence how their employer fills out Form W-2.  

Furthermore, only full-time employees are usually required to complete Form W-4. For example, independent contractors are usually not required to complete Form W-4. This is because taxes aren’t traditionally withheld from an independent contractor’s compensation, so the form isn’t really necessary. 

What Each Form Means

The purpose of Form W-4 is to inform employers how much money to withhold from an employee’s paycheck. Form W-2 contains information regarding an employee’s annual wages and how much in taxes were withheld throughout a particular calendar year. 

When These Forms are Required 

Employees usually fill out Form W-4 when starting a new job or form of employment, and any time there is a change with their withholding allowances. For example, these situations may prompt you to alter your tax withholding allowances:

  • Getting married
  • Getting divorced
  • Acquiring an additional job
  • Having children 

Form W-2, on the other hand, is required on a much more regular basis. Employers will fill out Form W-2 every year for employees to reference when completing their state and local taxes and/or their federal taxes. Typically, employers must fill out Form W-2 for distribution by January 31st each tax year. 

Filing With the Social Security Administration

While employers should keep Forms W-4 for their business records, they don’t usually have to file them with any official tax agency or provide their employees with a copy of the form. Alternatively, employers must file Forms W-2 with the Social Security Administration as well as distribute a copy to their employees. 

Other Tax Documents

Form W-2 isn’t the only document people use when completing their state and/or federal taxes. Below are some common forms people usually need when doing their yearly taxes.

FAQs: Form W-2, Form W-4, and Other Federal Income Tax Documents 

What is the purpose of payroll tax forms, and how do Forms W-2 and W-4 fit into this category?

How do I know my tax year when filling out these forms?

The tax year refers to the 12-month period for which tax information is reported. For most taxpayers, the tax year is the calendar year from January 1 to December 31. Forms W-2 and other tax documents typically cover this period.

Why is my taxpayer identification number important on these forms?

A taxpayer identification number (TIN), such as a Social Security Number (SSN), is crucial for accurately reporting tax information. Employers use your TIN to report your earnings and tax withholdings to the IRS on Form W-2.

What is the difference between Medicare taxes and Medicare tax withheld?

Medicare taxes are payroll taxes that fund the Medicare program. The Medicare tax withheld refers to the amount deducted from an employee’s paycheck for Medicare taxes, as reported on Form W-2.

How does income tax withholding work with Forms W-2 and W-4?

Income tax withholding is the process of deducting federal income taxes from an employee’s paycheck. Form W-4 allows employees to specify how much tax should be withheld based on their filing status and allowances. Form W-2 then reports the total amount withheld for the year.

What should I do if I believe my federal income taxes withheld are incorrect?

If you think there is an error in the amount of federal income taxes withheld from your paycheck, review your Form W-4 to ensure it is filled out correctly. You can submit a new W-4 to your employer to adjust your withholding. Additionally, you can consult with a tax professional for guidance.

How does Form W-2 affect my tax liability?

Are local income taxes included on Form W-2?

Yes, local income taxes withheld from your paycheck are reported on Form W-2. This form includes separate boxes for federal, state, and local income tax withholdings.

How do I update my filing status on Form W-4?

Your filing status, such as single, married, or head of household, affects your tax withholding on your W-4. To update your filing status, complete a new Form W-4 and submit it to your employer. Changes in your personal circumstances, like marriage or divorce, may necessitate updating your filing status.

Who should I contact if I have questions about my local income taxes?

If you have questions about local income taxes, contact your local tax department. They can provide specific information about local tax regulations and how they apply to your situation.

How can I estimate how much tax will be withheld from my paycheck?

How do Forms 1040 and 1040-SR relate to Forms W-2 and W-4?

Forms 1040 and 1040-SR are used to file your annual federal tax return. Form W-2 provides the necessary information about your earnings and tax withholdings, which you need to complete these forms.
