Every January, workers across the country receive a W-2 Wage and Tax Statement from their employer. It is the most important tax document most people deal with each year, yet many workers are unsure what every box means or what to do with it. This guide explains it all.
What Is a W-2?
A W-2 is a form your employer sends to you and to the IRS each year. It reports your total wages earned and the total taxes withheld during the calendar year. You use the numbers on your W-2 to fill out your Form 1040 when you file your federal income tax return.
Your employer is required by law to send your W-2 by January 31. If you have not received it by mid-February, contact your payroll department or HR team.
Key Boxes on the W-2 Explained
- Box 1 — Wages, tips, other compensation: Your total taxable wages for the year. This is gross pay minus pre-tax deductions like 401(k) and health insurance premiums.
- Box 2 — Federal income tax withheld: The total federal income tax your employer withheld from your paychecks throughout the year.
- Box 3 — Social Security wages: Wages subject to the 6.2% Social Security tax. May differ from Box 1 if you have 401(k) contributions.
- Box 4 — Social Security tax withheld: Should equal 6.2% of Box 3.
- Box 5 — Medicare wages: Wages subject to the 1.45% Medicare tax.
- Box 6 — Medicare tax withheld: Should equal 1.45% of Box 5 (plus the extra 0.9% if wages exceed $200,000).
- Box 12 — Codes: Various benefit-related amounts, including 401(k) contributions (code D), HSA employer contributions (code W), and others.
- Box 16 & 17 — State wages and tax: Texas has no state income tax, so these boxes are usually blank for Texas workers.
Multiple W-2s
If you worked more than one job during the year, you will receive a separate W-2 from each employer. Add up the Box 2 amounts from all W-2s when completing your federal return.
When Box 2 Is Zero
If your employer did not withhold federal income tax, it does not mean you owe nothing. You may still owe taxes when you file, depending on your total income. This is common for part-time workers or those who claimed too many allowances on their W-4.
Corrected W-2 (W-2c)
If your employer made an error on your W-2, they will issue a corrected form called a W-2c. Always use the most recent version when filing.
