The W-2 and W-4 forms are important IRS documents for your business and staff. Form W-4 is used to provide information about how much tax should be withheld from your employees’ paychecks, while Form W-2 is used to report annual income and taxes to the IRS. In this guide, we’ll compare both in detail and walk you through when to use each of them.

The difference between the two payroll forms is that the W-4 is an input document and the W-2 is an output document. Employees, typically new hires, use the W-4 form to provide their company’s payroll department with information on how much tax to withhold from their earned income. Then, at the end of every year, employers use the W-2 form to report an employee’s annual income and taxes withheld.
Here is how data flows from the W-4 form to the W-2 form for a typical employee.
The W-2 is also provided by the employer to the employee at the end of each year. Aside from showing a summary of the annual gross income, the form includes information on how much was taken out of the gross pay for deductions (such as state and local taxes).

W-4: When to Use It and Where to Get It
The W-4 form, also known as the Employee’s Withholding Certificate, is provided by the employer once an employee has accepted an offer of employment. New hires need to complete and submit the form to their company’s HR or payroll department before receiving their first payroll payment. Aside from new hires, existing employees with life and work changes (such as marriage, divorce, a new baby or dependent, and having more than one job) that may affect their taxes also have to complete a new W-4 form.
In the event that your employees expect their wages to result in zero tax liability, they can claim a W-4 exemption. For example, if the standard deduction for a married couple is $24,000 and your sole-wage earner staff knows they will earn less than that annually, they may want to consider claiming an exemption from withholding.
Upon receiving the form, the payroll department will use the information on the W-4 to determine how much in federal, state, and local taxes need to be deducted from the employee’s paycheck. In addition, a copy of the signed W-4 should be kept by the employer in case the IRS requests it.
If newly hired employees fail to complete the W-4 before their first pay cycle, the company should process payroll as if the employee had chosen a “single” civil status with zero children or dependents—this will result in you withholding taxes at the highest rate. Employers can also use the staff’s Form W-4 from the previous year as the basis for calculating how much tax to withhold.

State-Specific W-4 Forms
There are several states (such as Colorado, Minnesota, and Mississippi) that use the W-4 as is to determine state tax withholding. Most other states (like Georgia, Illinois, and Kentucky) have their own versions of the W-4. Check with your state whether or not you need to use the federal form or a state-specific W-4.
Where to Find a W-4
The employer provides the W-4 form to their employees. It is downloadable from the IRS website, either in English or Spanish.
- Download IRS Form W-4 from the IRS website.
- Download IRS Form W-4 (Spanish) from the IRS website.
- View instructions for completing IRS Form W-4 from the IRS website.
Employers can also get the form from their payroll system or a payroll service provider. In addition, some companies include this form, along with I-9 and other documentation, as mandatory documents that new hires need to complete and submit during onboarding.
However, if you’re a small business running payroll by hand, managing employee and employer payroll taxes and preparing tax forms can be time-consuming.

W-2: When to Use It and Where to Get It
Officially known as IRS Form W-2 Wage and Tax Statement, the W-2 is a year-end tax document that employers must provide. It contains information about the employee, their earnings (such as gross pay, bonuses, and tips), and any deductions taken out for taxes, savings, retirement, and childcare.
The IRS requires that a prior year W-2 be sent to them and your employees by Jan. 31. For example, for the 2021 tax year, W-2 forms must be sent by Jan.31, 2022. Note you have to provide a W-2 to every person who worked for you as an employee during the prior tax year—whether they are still employed with your company or not.
For businesses that use payroll systems, such as Gusto, note that some offer self-service options that allow employees to download their own year-end W-2. This is helpful in case they’ve moved and you don’t have an updated USP mailing address. You can send them a secure email link to their W-2 instead of mailing the forms, enabling you to comply with IRS requirements and making it possible for employees to file their taxes.
If you want to know how to fill out the forms, check out our W-2 guide. Not only does it contain helpful tips, but it also provides useful information on how to submit it.
Where to Get a W-2
Employees can get their year-end W-2 forms from current and former employers (in case they worked at different companies for the prior tax year). Employers either send the form through mail, or you can download the document through an online self-service portal.
If you’re handling payroll yourself, you can download a blank W-2 from the IRS.gov website.
While the W-2 and W-4 are both important IRS tax documents, each form has a different purpose. A W-4 form is the input form used to gather an employee’s tax-related information, while the W-2 is an output form that employers provide to employees at year-end so that they can file payroll taxes. Knowing what these forms are and explaining the difference between both to your employees can prevent them from being caught off guard at tax time.
If you need help preparing your W-2 forms or collecting W-4s, consider using a payroll solution like Gusto. With its self-service portal, your employees can enter all of their W-4 information online, and it will automatically transfer into your payroll system. In addition, the software will prepare your year-end W-2 forms and make it accessible for your employees to download on demand, so you don’t have to do it manually. Sign up for a free trial today.
