What Is A W-2 Form? Tips for Employers on Completing Employee Tax Documents

The W-2 Form is a tax document that employers are required to send to each employee as well as to the Internal Revenue Service at the end of the year. The W-2 Form lists the details of an employee’s annual income as well as the amount of taxes the employer withheld from their paychecks. W-2 forms differ from the W-4 form, which is an input document that tells a company’s payroll department its tax withholding obligations for each employee. As a small business owner, you must learn how to properly complete a W-2 Form for employees and the IRS to accurately report their workers’ income and tax contributions to the federal government.

These topics explain what a W-2 Form is and how employers should fill them out:

What Is the Purpose of a W-2 Form?

The purpose of the W-2 Form is to report the wages and salaries paid to employees and the federal, state and local taxes that were withheld from their earnings. Employees need the information detailed as part of the W-2 Form to complete their yearly income tax returns. Businesses are legally required to send out W-2s to workers whom they pay a salary or wage and from whom the employer withheld any of the following:

  • Income tax
  • Social security tax
  • Medicare

Employers don’t need to provide W-2 Forms to independent contractors and self-employed workers, who use different forms to file taxes. The W-2 forms give the IRS and the Social Security Administration information that allows them to verify a person’s income tax return.

What’s Included on a W-2 Form?

A W-2 Form includes important details that employees need to file their income taxes and that the IRS needs to verify a person’s tax statements. The W-2 always has the same fields of information, regardless of the employer or industry.

The W-2 is divided into two sections, one for state details and one for federal details, since employees need to file taxes on both the state and federal level. W-2 Forms include the following information:

1. Business Information

You’ll need to include some important details about your business on the W-2 Forms you send to employees. Those business details include:

  • Your Employer ID Number
  • Your business name
  • Your business address
  • Your business’s State Tax ID Number, which can be found through your state’s department of revenue

2. Employee Information

Your W-2 forms need to include identifying information about each of your employees, including:

  • Employee name
  • Home address
  • Social Security Number

3. Employee Earnings

Next on the form, you’ll need to add information related to the employee’s total wages or salary and withheld taxes for the year, including:

  • Total wages or salary, income from tips and any other compensation
  • Social security wages
  • Medicare wages
  • Social security tips and allocated tips

4. Retirement Plan Details

On each employee W-2, you will need to indicate whether the worker takes part in a retirement plan within your business, whether the person is a statutory employee or if they received third-party sick pay. This information is included in Box 12 of the W-2 Form.

5. Benefits Plan Details

The W-2 Form includes information about an employee’s benefits plan deductions that need to be reported as part of their income tax filing. This information goes in Box 13 of the form.

When is the W-2 Form Due?

The W-2 Forms must be submitted to the Social Security Administration by January 31 of the next year. So, if you’re sending out W-2 Forms for the 2018 tax year, you’ll need to file them with the SSA no later than January 31, 2019, for both mailed and online filings.

You must also send the W-2 Forms to employees by January 31 of the next year. The best way to file your W-2 Forms is to first send them to employees in early January, so if there are any errors or omissions on the forms you completed, you can fix the mistakes before sending them off to the SSA by the end of the month.
