By January 31 of each year, your employer is required to send you an Internal Revenue Service (IRS) Form W2 form so you can file your tax return. Boxes A through F are straightforward, listing yours and your employer's addresses and federal tax identification numbers. However, it is important to know how to read the other boxes and transfer the information to your tax forms.
Read the Various Boxes on a W-2 Form
Step
Read Box 1 for your wages, tips and other compensation. This is the total amount that your employer has a record of paying you during the previous calendar year. It includes wages, tips, commissions and any bonuses you might have received. Transfer this amount to your Form 1040 line 7.
Step
Check Box 2 for the amount of federal income tax that your employer withheld from your wages during the previous year. Transfer this amount to Form 1040, line 62 federal tax withheld.
Step
Scan Box 3 for the amount of earnings your employer paid you that is subject to Social Security tax.
Step
See Box 4 for the amount of Social Security tax that was withheld. It should equal 6.2 percent of the amount in Box 3.
Step
See Box 5 for the total amount your employer paid to you that is subject to Medicare tax.
Step
Check if the amount in Box 6 is 1.45 percent of the figure in Box 5. It is the total amount of Medicare tax that was withheld from your pay.
Step
Look at Box 7 for any tips you earned that you reported to your employer.
Step
Check Box 8 for the tips that your employer allocated to you. This figure is in addition to the amount in box seven.
Step
Box 9 is not presently used by the IRS.
Step
Read Box 10 for dependent care benefits. You chose to defer this amount of income from tax and paid it to your dependent care provider.
Step
Scan box 11 for the total amount that you received from your employer's nonqualified plan.
Step
Boxes 12a through 12d will list various items, such as your pre-tax contributions to your employer's 401(k), SEP or SIMPLE plan, nontaxable sick pay and combat pay that is excludable.
Step
Read Box 13. One box within it will be checked if it applies to you: statutory employee, retirement plan or third-party sick pay.
Step
Get additional information from Box 14. For example, employers might list your union dues or the after-tax 401(k) contributions you made.
Step
Verify your state in Box 15. Box 16 lists the amount of your wages that are subject to state taxes. Box 17 is the amount of state tax that was withheld for the state listed in box 15.
Step
See Box 18 for wages and tips that were subject to local income tax. Box 19 shows the amount of tax withheld for the city or locality that appears in Box 20.
