Comprehensive Guide to Understanding Form W-2
Learn everything about Form W-2, including its purpose, how to fill it out, submission deadlines, penalties for late filing, and the difference between W-2 and W-4. This detailed guide helps employers and employees understand tax reporting responsibilities to ensure compliance and avoid fines.

The W-2 form is a crucial document used by employers to report wages, tips, and tax withholdings to the IRS. It provides employees with details about their annual earnings, taxes deducted, and other contributions like 401(k) and health savings accounts. Employers are required to prepare and file W-2 forms for each employee, ensuring accuracy to avoid penalties. The form includes personal information such as Social Security numbers and addresses, which must be verified before submission. Timely filing prevents penalties and ensures compliance with IRS regulations.
Employees should review their W-2 for correctness and contact their employer if discrepancies occur. Employers can file W-2s online, especially for larger businesses. Failing to submit W-2 forms on time may result in fines ranging from $75 to $500 per form, along with potential legal consequences. The W-2 is distinct from the W-4, which employees complete when starting a new job to determine tax withholding. Accurate W-2 and W-4 forms are vital for proper tax reporting and compliance.
