What do the W-2 Boxes and W-2 Form Codes mean?
The W2 boxes and codes show the wages you’ve earned and any taxes paid through withholding. To help you understand your Form W2, we’ve outlined each of the W-2 boxes and the corresponding W2 box codes below.
Box 1 — Shows your wages, tips, prizes, and other compensation for the year. Include this amount on the wages line of your return. If you have more than one Form W-2, or you are married and your spouse also has one or more W-2s, the total of all forms’ Box 1 will be shown on Form 1040, line 1.
Box 2 — Shows the total federal income tax that was withheld from your paycheck for the year. Include this amount on the federal income tax withheld line of your return (Form 1040, line 16).
Box 3 — Shows your wages subject to Social Security tax. (This amount may not be the same as reported in Box 1)
Box 4 — Shows the amount of Social Security tax withheld from your pay.
Box 5 — Shows your wages subject to Medicare tax. This amount, which also may not be the same as the amount reported in Box 1, might be required on Form 8959 if your income is high enough. See Form 1040 instructions to determine if you’re required to complete Form 8959.
Box 6 — Shows the amount of Medicare tax withheld. This amount includes these:
- 1.45% Medicare tax withheld on all Medicare wages and tips shown in Box 5
- 0.9% Additional Medicare tax on any of those Medicare wages and tips above $200,000
Box 7 — Shows any tip income you reported to your employer.
Box 8 — Shows tip income allocated to you by your employer. This amount isn’t included in W-2 Boxes 1, 3, 5, or 7. For information on how to report tips on your return, see your Form 1040 instructions or IRS Pub. 531, Reporting Tip Income .
You must file Form 4137: Social Security and Medicare Tax on Unreported Tip Income with your return. You’ll report at least the allocated tip amount unless you can prove a smaller amount with adequate records. If you have records that show the actual amount of tips you received, report that amount even if it’s more or less than the allocated tips. On Form 4137, you’ll figure the Social Security and Medicare tax owed on the allocated tips shown on your W-2(s). By filing Form 4137, your Social Security tips will be credited to your Social Security record (used to figure your benefits).
