Once you send Forms W-2 to your employees, you don’t have to worry about the annual form until next year. Or, do you? If you don’t know how to read a W-2 form, you may run into problems.
Your employees might come to you with questions about Form W-2. And, your employees may think you made a mistake if their W-2 Box 1 value is lower than what they believe they earned.
As an employer, you need to know how to read a W-2. That way, you can verify your values are correct and help clarify the confusion.
How to read a W-2 form
You might have your Form W-2 responsibilities down to a science. Input employee information; send copies to employees; file the form with the SSA and state, city, or local tax department; and repeat the following year.
Transferring information onto Form W-2 and distributing copies is one thing, but knowing how to read a W-2 Wage and Tax Statement is another.
Whether you complete Forms W-2 on your own, use payroll software, or have a tax preparer, you should be semi-fluent in decoding Form W-2.
As a generalization, Form W-2 boxes show identification, taxable wage, taxes withheld, and benefits information.
Boxes A-F are straightforward. They list identifying information about your business and employee. The numbered boxes, Boxes 1-20, can get a little more tricky.
If you want Form W-2 explained, dive into each box’s purpose below.
Box A: Employee’s Social Security number
Box A shows your employee’s Social Security number. Social Security numbers are nine digits that are formatted like XXX-XX-XXXX.
If your employee applied for a Social Security card and has not received it, don’t leave the box blank. Instead, write “Applied For” in Box A on the Social Security Administration copy. When the employee receives their SS card, you must issue a corrected W-2.
Box B: Employer Identification Number (EIN)
Box B shows your Employer Identification Number. EINs are nine-digit numbers structured like XX-XXXXXXX.
The number you enter in Box B is the same on every employee’s Form W-2. The IRS and SSA identify your business through your unique EIN.
Never use your personal Social Security number on Forms W-2. If you do not have an Employer Identification Number, you must apply for an EIN before filing Form W-2. Then, mark “Applied For” in Box B.
Box C: Employer’s name, address, and ZIP code
Box C further identifies your business by listing your company’s name and address. Use your business’s legal address, even if it’s different than where your employees work.
Your employees may wonder whether the address is incorrect if it’s different than their work address. Verify your legal business address and ensure your employee it is accurate.
Box D: Control number
Box D might be blank, depending on whether your small business uses control numbers or not.
A control number identifies Forms W-2 so you can keep records of them internally. If you don’t use control numbers, leave this box blank.
Boxes E and F: Employee’s name, address, and ZIP code
Box E shows the employee’s first name, middle initial, and last name. Reference the employee’s SSN to enter their name correctly.
Enter the employee’s address in Box F.
Box 1: Wages, tips, other compensation
Box 1 reports an employee’s wages, tips, and other compensation. This is the amount you paid the employee during the year that is subject to federal income tax.
Payments not subject to federal income tax include pre-tax retirement plan contributions, health insurance premiums, and commuter benefits.
The wages you report in Box 1 might be higher or lower than other wages on Form W-2. This is not a mistake.
For example, an employee’s Box 1 wages can be lower than Box 3 wages. Some pre-tax benefits are exempt from federal income tax but not Social Security tax.
Box 2: Federal income tax withheld
Box 2 shows how much federal income tax you withheld from an employee’s wages and remitted to the IRS.
Federal income tax withholding is based on the employee’s taxable wages, filing status, and withholding allowances.
If your employee has a question about their refund amount or why they owe taxes, instruct them to Box 2. The IRS compares what the employee paid throughout the year in federal income taxes to their total liability.
Box 3: Social Security wages
Box 3 shows an employee’s total wages subject to Social Security tax. Do not include the amount of pre-tax deductions that are exempt from Social Security tax in Box 3.
The number in Box 3 should not be higher than the Social Security wage base. For 2019, the SS wage base is $132,900.
If you must report Social Security tips (Box 7), the total of Boxes 3 and 7 must be less than $132,900.
Box 4: Social Security tax withheld
Box 4 reports how much you withheld from an employee’s Social Security wages and tips.
The employee portion of Social Security tax is 6.2% of their wages, up to the SS wage base. Box 4 cannot be more than $8,239.80 ($132,900 X 6.2%).
Box 5: Medicare wages and tips
You must enter how much the employee earned in Medicare wages and tips in Box 5.
An employee’s Box 5 value is generally the same as Box 4’s amount. However, there is no Medicare wage base. If the employee earned above the Social Security wage base, the number in Box 5 is higher than Box 3.
For example, the employee earned $150,000. The employee’s Social Security wages, (Box 3) should show $132,900 while Box 5, Medicare wages and tips, displays $150,000.
Box 6: Medicare tax withheld
Box 6 displays how much you withheld from an employee’s wages for Medicare tax. The employee share of Medicare tax is 1.45% of their wages.
The amount in Box 5 multiplied by the Medicare tax rate should equal Box 6. But if the employee earned above $200,000 (single), their tax liability should be greater.
If you paid an employee above $200,000 (single), you should have also withheld the additional Medicare tax rate of 0.9% from their wages above $200,000.
Box 7: Social Security tips
If your employee earned tips and reported them, enter the amount in Box 7. Also, include these tip amounts in Boxes 1 and 5.
Again, the total of Boxes 7 and 3 should not be more than $132,900.
Box 8: Allocated tips
Report the tips you allocated to your employee in Box 8, if applicable. Allocated tips are amounts that you designate to tipped employees. Not all employers have to allocate tips to their employees.
Do not include the amount in Box 8 in Boxes 1, 3, 5, or 7. Allocated tips are not included in taxable income on Form W-2. Employees must use Form 4137 to calculate taxes on allocated tips.
Box 9: Verification code
Box 9 can either be blank or show a verification code.
Verification codes are written as XXXX-XXXX-XXXX-XXXX. For more information on this new initiative, check out the IRS’s website.
Box 10: Dependent care benefits
Did you give an employee dependent care benefits under a dependent care assistance program? If so, include the total amount in Box 10.
Dependent care benefits under $5,000 are nontaxable. Benefits over $5,000 are taxable. If you gave an employee more than $5,000, you must report the excess in Boxes 1, 3, and 5.
Box 11: Nonqualified plans
Box 11 reports employer distributions from a nonqualified deferred compensation plan to an employee.
Include the distribution amounts in Box 1, too.
Box 12: Codes
There are a number of W-2 Box 12 codes you may need to put on an employee’s Form W-2. If applicable, add the codes and amounts in Box 12.
These codes and values may lower the employee’s taxable wages.
Let’s say an employee elected to contribute $1,000 to a retirement plan. You would write D | 1,000.00 in Box 12.
Box 13: Checkboxes
Box 13 should not include values. Instead, you must mark the boxes that apply. There are three boxes within Box 13:
- Statutory employee
- Retirement plan
- Third-party sick pay
For example, if you entered Box 12 code D to show the employee’s retirement contributions, you must also check the ‘Retirement plan’ box.
Box 14: Other
Report information in Box 14 that you didn’t report anywhere else, including vehicle leases payments, state disability insurance taxes withheld, and health insurance premiums deducted.
Box 15: State | Employer’s state ID number
Like Box B, Box 15 identifies your business’s employer ID number with your state. Mark your state using the two-letter abbreviation (e.g., OH). Then, include your state EIN.
Some states do not require reporting. Leave Box 15 blank if you have no reporting requirement with your state.
If you do not have an employer’s state ID number and need one, contact your state.
Box 16: State wages, tips, etc.
Box 16 shows an employee’s wages that are subject to state income tax. If the employee works in a state with no state income tax, leave Box 16 blank.
An employee’s Box 16 amount may differ from Box 1. This is not a mistake. Some wages are exempt from federal income tax and not state income tax.
Box 17: State income tax
Report how much you withheld for state income tax in Box 17. If you did not withhold state income tax, leave Box 17 blank.
Box 18: Local wages, tips, etc.
If your employee’s wages are subject to local income tax, include their total taxable wages in Box 18. Leave this box blank if the employee works in a locality with no income tax.
The amount you list in Box 18 might be different than Boxes 1 and 16.
Box 19: Local income tax
Report any local income tax withheld from the employee’s wages in Box 19. Leave this box blank if it is inapplicable.
Box 20: Locality name
Box 20 should show the name of the city or locality.
