What is a W-2 form primarily used for?

The W-2 form is primarily used to report annual wages and tax deductions for employees. Employers are required to provide this form to their employees at the end of each tax year, and it summarizes the total earnings for the year along with the amount of federal, state, and other taxes withheld from the paycheck. This information is crucial for employees when filing their federal and state income tax returns, as it provides a clear summary of their income and the taxes already paid.

Having precise records of wages and deductions helps ensure that employees file their taxes correctly and understand their tax liabilities or potential refunds. The W-2 form thus serves as a key document in the tax filing process, contributing to accurate reporting and compliance with tax laws.
