W2

The W-2 form is a key tax document. You need it to file your taxes each year. But what exactly is it? And why is it so important? Let’s break it down.

What Is a W-2 Form?

A W-2 form, or the “Wage and Tax Statement,” is a paper or electronic form that your employer sends to you and the government every year. It clearly shows how much money you earned and how much was taken out for taxes.

Here’s what your W-2 form tells you:

• Your total wages for the year.
• How much federal income tax was withheld.
• How much state and local income tax was withheld.
• Money taken out for Social Security and Medicare.

This information helps you fill out your annual tax return. The IRS and the Social Security Administration (SSA) also use this information. The IRS makes sure you report the right income. The SSA tracks your earnings to figure out your future Social Security benefits.

Think of your W-2 form as your official report card from your job to the government about your pay.

Who Gets a W-2 Form?

You get a W-2 form if you are considered an employee of a company. This means your employer takes money out of your paycheck for taxes before you get paid. These people are sometimes called “W-2 employees.”

It does not matter if you work full-time, part-time, or are just a temporary worker. If your employer withholds taxes from your paycheck, they must give you a W-2 form.

If you work as an independent contractor or freelancer, you usually get a different form called a 1099. We’ll look at the difference later.

When Should You Receive Your W-2?

There’s a strict deadline for employers to send out W-2 forms.

Employers must send your W-2 form to you and file a copy with the Social Security Administration by January 31st each year. This deadline covers the income you earned the year before.

For example, if you worked in 2024, your employer must send you your W-2 form for 2024 by January 31, 2025.

Getting your W-2 on time is important. It gives you time to gather your tax documents and file your return by the usual tax deadline in April.

Reading Your W-2: What the Boxes Mean

Your W-2 form has several boxes, each with important information. Understanding these boxes helps you file your taxes correctly.

Let’s zoom in on Box 12 and the different codes.

This seems like a lot, but your tax software or tax preparer will use these codes to accurately complete your tax return. You can find a complete list and explanation of all W-2 codes in the official instructions for Forms W-2 and W-3 provided by the IRS. You can find this detailed guide here: 2025 General Instructions for Forms W-2 and W-3.
