Understanding Form W-2

We have understood what Form W-2 is, the information it contains, and copies to be created by the employer. However, it’s also important to understand the format and description of different sections within Form W-2. So let’s get into it for your understanding.

Left Side

On the left side of Form W-2 are different boxes labeled with alphabets from A to F. Let’s briefly describe each box on the left side of Form W-2.

Box A

It contains the Social Security Number(SSN) of the employee. Since your employer has to fill the Form W-2, you should double-check that the number entered in box A is correct. In case there is an error in SSN, your tax return filing process will be subject to slow processing.

Box B

Box B contains the nine-digit employer’s EIN. EIN stands for Employer Identification Number or FTIN(Federal Tax Identification Number). EIN can be regarded as equivalent to SNN in importance. IRS requires an EIN number to identify the taxpayers who are supposed to file several business tax returns.

Box C

Every business has an official address that has to be mentioned for correspondence. It’s usually the legal address mentioned in documents; the actual working address might not be the same. Box C on the left side of Form W-2 contains the employer’s address.

Box D

Box D is an important box related to the employer’s annual wages and benefits. It contains a control number that is internal to the employer.

Your employer or your payroll department issues the control number. Don’t get overwhelmed to see a blank Box D because, in that case, your employer might not be using any control numbers.

Box E & F

Box E and F are collectively shown on Form W-2 as a big block containing the name and address. The name and address mentioned in these boxes are of the employee.

The name should be the same as reported on Social Security Card(SSA) and should be written in Box E. Box F is dedicated to the address of the employee, and it should contain your mailing address without punctuation.

In case your name is not correct on Form W-2, you will fill the new Form, and for the wrong address, the employer can change the address in his records for convenience.

Box A, E, and F are the most significant boxes that you should double-check the accuracy of.
