Form W-2 (Wage and Tax Statement) is an IRS tax form that employers must provide to employees and the Social Security Administration annually, reporting total wages paid and taxes withheld during the previous calendar year. This essential document is required for filing your federal and state income tax returns and serves as official proof of your earnings and tax payments.
Employers must furnish Form W-2 to employees by January 31st following the tax year. The form includes critical information such as total wages, salaries, tips, and other compensation; federal income tax withheld; Social Security and Medicare wages and taxes; state and local income taxes withheld; and retirement plan contributions. Box-by-box, Form W-2 provides a comprehensive breakdown of your compensation and withholdings, with numbered boxes corresponding to specific categories of income and deductions.
Employees receive multiple copies of Form W-2: Copy B for filing with your federal tax return, Copy C for your personal records, and Copy 2 for filing with your state, city, or local tax return if applicable. You’ll need the information from Form W-2 to accurately complete Form 1040 or other individual income tax returns. The wages reported in Box 1 represent your taxable federal income, while Boxes 3 and 5 show wages subject to Social Security and Medicare taxes, which may differ due to pre-tax deductions.
Common items that appear on Form W-2 include employer-sponsored health insurance premiums, 401(k) or other retirement plan contributions (shown in Box 12 with specific codes), dependent care benefits, adoption assistance, and educational assistance. If you have multiple jobs during the year, you’ll receive a separate W-2 from each employer, and all must be reported on your tax return.
If you don’t receive your W-2 by mid-February, contact your employer immediately. If the issue remains unresolved, contact the IRS for assistance. Form W-2 differs from Form W-4, which determines withholding amounts, and Form 1099, which reports non-employee compensation to independent contractors.
