Form W-2: Wage and Tax Statement reports your wages and taxes withheld from your wages. Your employer is required to give you a 2018 W-2 by Jan. 31, 2019. Your employer keeps a copy for recordkeeping.
A copy of your W-2 is sent to:
- Social Security Administration (SSA)
- State or local governments for which taxes are withheld
You’ll refer to some of the W-2 boxes to complete your return. Some W-2 boxes are for informational purposes only.
Box a: Employee’s Social Security number — If the number is incorrect due to a typographical error:
- Report it to your employer immediately
- Get a corrected W-2
All payments withheld from your wages are credited to the Social Security number (SSN) shown. If your SSN in the payroll system — and on your W-2 — is incorrect, your employer must fix this. An incorrect SSN means your payments aren’t credited to you for:
- Income tax
- Social Security
Box b: Employer’s federal ID number — This is your employer’s identification number with the IRS. It’s the equivalent of your SSN or individual taxpayer identification number (ITIN). This number must be valid and match the IRS’s records if you want to e-file your return.
Box c: Employer’s name, address, and ZIP code — If you work for a corporation, this is usually the address of the main office or headquarters. It’s not necessarily the building where you work.
Boxes e and f: Employee’s name and address — Your full name and current address
Box 1: Wages, tips, and other compensation — The taxable amount of compensation your employer paid you. This includes:
Enter the amount in this box on Forms 1040 and 1040A, Line 7, or Form 1040EZ, Line 1.
Box 2: Federal income tax withheld — The total amount of federal income tax your employer withheld from your wages. Enter the amount in this box on:
- Form 1040, Line 62
- Form 1040A, Line 36
- Form 1040EZ, Line 7
Box 3: Social Security wages — The amount of earnings your employer paid you subject to Social Security tax. This doesn’t include tips. This amount might be more than the amount in Box 1 if some income subject to Social Security tax isn’t subject to income tax. Ex: Amounts you contribute to a tax-deferred retirement plan like a 401(k) or a 403(b) plan.
For 2018, the total of Boxes 3 and 7 shouldn’t be more than $118,500.
Box 4: Social Security tax withheld — The amount of Social Security tax withheld on your wages. For 2018, this amount can’t be more than $7,347. This amount should equal 6.2% of the amount in Box 3.
If you worked for more than one employer, the total withheld might be more than $7,347. If so, the excess is treated as a tax payment. This payment will increase your refund or decrease your balance due. See Form 1040, Line 69.
Box 5: Medicare wages and tips — The total amount of earnings your employer paid you subject to Medicare tax. There’s no limit on the amount of wages that might be subject to Medicare tax.
Box 6: Medicare tax withheld — The amount of Medicare tax withheld on your wages. This amount should equal 1.45% of the amount in Box 5.
Box 7: Social Security tips — This lists the tips you received that you reported to your employer. Box 7 and Box 3 combined are used to figure the Social Security and Medicare tax you owe on tips you didn’t report to your employer.
Box 8: Allocated tips — The amount of tips your employer allocated to you. This amount is in addition to the amount you reported, which is in Box 7. The allocation is usually based on credit card receipts and IRS formulas.
If you have an amount in this box, you might need to complete Form 4137 to pay these taxes on the amount:
- Social Security tax

You usually must include the amount in taxable wages, Box 8 on your return. To learn when you might not need to report this amount, see Publication 531.
