Form W-2 is a statement of wages earned and taxes paid by you while working for a single employer during a calendar year. Your employer is required to provide you with a copy of your W-2, along with submitting copies to the Social Security Administration (SSA) and the Internal Revenue Service (IRS).

The W-2 includes various details, such as:

Employee information: name, address, and Social Security number.

Employer information: name, address, and Employer Identification Number (EIN).

Earnings: total wages, salary, bonuses, and other compensation.

Tax withholding: federal income tax withheld, Social Security tax, and Medicare tax.

State and local taxes: state and local income taxes withheld, if applicable.

Benefits: the value of certain benefits provided by the employer.

Other information: this may include information about retirement plan contributions, health insurance premiums, and other relevant details.

Employees use the information on their W-2 to prepare their individual income tax returns. It is an essential document for both employers and employees during the tax-filing season.
