What Is a W-2 Form? How to Read It

A W-2, formally the Wage and Tax Statement, is the form your employer sends you and the IRS each year reporting the wages you earned and the taxes withheld from your paychecks. Employers must furnish it by January 31, and you need it to file your federal and state returns. It differs from a 1099: a W-2 covers employee wages with taxes already withheld, while a 1099 reports payments to contractors who had nothing withheld.

What Form W-2 is and who sends it

If you are an employee, your employer is required to give you a W-2 for any year they paid you at least $600, or withheld any income, Social Security, or Medicare tax from your pay. One copy comes to you, another goes to the Social Security Administration, and your state gets one too. The form is the official record of what you earned and what was already paid toward your taxes, which is why the IRS expects the numbers on your return to match it.

You should receive your W-2 by January 31 following the tax year. For the 2025 tax year, employers must send it by early February 2026 (the statutory date is January 31). Most employers now provide it electronically as well as by mail. If you worked more than one job, you get a separate W-2 from each employer, and you report all of them.

How to read the boxes on a W-2

The lettered boxes on the left identify you and your employer. The numbered boxes on the right carry the money. These are the ones that matter most when you file.

Box 1 is usually smaller than Box 3 because pre-tax retirement contributions reduce your taxable wages but not your Social Security wages. Code DD in Box 12 is informational only; it shows what your health plan costs but does not change your tax. The federal tax in Box 2 is money you already paid, so it is credited against your total tax when you file, and it is a big reason many people get a refund.

W-2 versus 1099: employee or contractor

The form you receive tells you how the tax system treats your work. A W-2 means you are an employee with taxes withheld. A 1099-NEC means you are an independent contractor who is responsible for your own tax.

Contractors usually deduct business expenses against their income, so keeping clean books matters, and many start by turning bank statements into a tidy expense spreadsheet before tax time. If you are not sure which category you fall into, our guide on 1099 versus W-2 walks through the difference, and the form you fill out for a new job is covered in how to fill out a W-4.

What to do if you do not get a W-2

You still have to report the income even if the form never arrives. Start by contacting your employer or former employer to confirm your address and ask for a copy. If it is still missing by late February, you can call the IRS, which will contact the employer on your behalf. As a last resort you can file using Form 4852, a substitute for the W-2, estimating your wages and withholding from your final pay stub of the year.

Filing without the actual form is riskier because the numbers need to match what your employer reported, so a copy is always better than an estimate. If you are missing forms across the board, our guide on how to file taxes without a W-2 covers the options in more detail.

How TaxFile uses your W-2

TaxFile reads your W-2 directly. You upload it, the software pulls the wages from Box 1, the federal tax from Box 2, and the state figures from Boxes 16 and 17 into the right lines, and it does the same for every W-2 if you had more than one job. It then prepares your federal and state return together, checks for the credits and deductions you qualify for, runs an error check, and e-files through an authorized IRS e-file provider only after you review and approve every line. You are not retyping boxes by hand or guessing where a number goes.

Frequently asked questions

When should I receive my W-2?

Your employer must send your W-2 by January 31 following the tax year, so for 2025 wages you should have it by early February 2026. Most employers provide it both by mail and electronically. If you have not received it by mid-February, contact your employer to confirm your address and request a copy.

What is the difference between a W-2 and a W-4?

A W-4 is the form you complete for your employer when you start a job to set how much tax is withheld from each paycheck. A W-2 is what your employer sends you after the year ends, reporting the wages they actually paid and the tax they actually withheld. You fill out a W-4; you receive a W-2.

Can I file taxes without my W-2?

Yes. If you cannot get your W-2 in time, you can file using Form 4852 as a substitute, estimating your wages and withholding from your last pay stub. Try to obtain the real form first, since the IRS matches your return against what your employer reported, and an estimate can trigger a correction later.

What is Box 1 on a W-2?

Box 1 shows your total taxable wages, tips, and other compensation for the year. It is the number you report as wages on your return. Box 1 is often lower than your gross pay because pre-tax items like 401(k) contributions and health premiums are subtracted before it is calculated.

Do I get a W-2 if I am a contractor?

No. Independent contractors receive a Form 1099-NEC when they are paid $600 or more, not a W-2, and no tax is withheld. As a contractor you report the income on Schedule C and handle your own income and self-employment tax, usually through quarterly estimated payments.
