Discover everything about the W-2 form, including its importance, key components, and how it affects your tax filing process. Learn about employee wage reporting, tax withholdings, and the importance of accuracy for smooth tax submissions, whether you're an employee or employer.

The W-2 form is a crucial document needed for filing tax returns, detailing your earnings and tax withholdings for the year. Employers must report employee wages, Social Security, Medicare, and tax deductions on this form, which is sent to both employees and the IRS by January 31. The form includes income data, taxes withheld, and other earnings like tips. It applies to salaried employees, excluding contractors or self-employed individuals who receive Form 1099. Historically filled out on paper, many now file electronically, streamlining the process.
W-2 forms contain key details such as employer identification numbers and employee income summaries for federal and state filings. Accurate reporting of your name and Social Security number is essential for proper tracking. Employers have a legal obligation to ensure data accuracy and correct any errors promptly to avoid penalties. When filing taxes, ensure you attach your W-2 form, whether submitting by mail or electronically, to verify your income and tax payments for the year.
