Who must file IRS Form W2?

Employers are required to file Form W-2 if they meet either of these conditions:

• The employer deducted any social security, Medicare, or income taxes from the employee's wages, regardless of the amount of wages paid.
• The employer paid $600 or more in earnings, even if no social security, Medicare, or income taxes were withheld.   

Form W-2 captures information such as the employee’s EIN, wages, bonuses, tips, and taxes withheld. This includes social security, Medicare, and income taxes. If an employer submits paper Form W-2, they should include Form W-3, the summary form. When filing the W-2s electronically, Form W-3 is not required.
