What a W-2 is and why you need it

A W-2 is a form your employer sends you that shows how much you earned and how much was withheld for taxes. You need it to file your federal income tax return. The IRS also gets a copy, so your tax return has to match what your employer reported — if it doesn't, the IRS will notice.

Your employer is legally required to send you a W-2 by January 31st each year for the previous calendar year. If you worked for multiple employers in a year, you'll get a separate W-2 from each one. You'll need all of them to file your taxes.

The W-2 shows your gross pay (total earnings before deductions), federal income tax withheld, Social Security tax withheld, Medicare tax withheld, and any other deductions. It also includes information about retirement contributions or health insurance premiums if your employer offers those.

Key Takeaways

  • Your employer must send your W-2 by January 31st for the previous year, either by mail or electronically if you've set that up.
  • If you haven't received your W-2 by early February, contact your employer's payroll or HR department directly — don't wait.
  • You can request a transcript from the IRS that shows wage information if your W-2 is lost or your employer won't provide one, though this takes longer than getting it from your employer.
  • Keep your W-2 with your tax records for at least three years in case the IRS asks questions about your return.

When your employer should send it and how to receive it

By law, your employer must mail or deliver your W-2 by January 31st. Many employers now offer the option to receive it electronically through a find portal or email instead of paper mail. If your employer offers electronic delivery, you may have set that preference when you were hired or during a benefits enrollment period.

Check your email (including spam folders) and any employee portals your company uses in late January. If your employer uses a payroll service like ADP or Guidepoint, you might receive your W-2 through that platform instead of directly from the company. Some employers mail W-2s, so check your mailbox as well.

If you recently changed jobs, make sure your employer has your current mailing address on file. If you moved and didn't update your address with payroll or HR, your W-2 may go to an old address.

What to do if you haven't received your W-2 by early February

If it's past February 15th and you still don't have your W-2, contact your employer's payroll department or HR office directly. Call or email and ask for the status. Provide your full name, Social Security number, and the year you're asking about. Most payroll departments can resend a W-2 within a few business days.

If your employer is unresponsive or no longer in business, you have another option: you can request a wage and income transcript from the IRS. This document shows the wage information the IRS received from your employer, which you can use to file your taxes. You can request this transcript online at IRS.gov, by phone at 1-800-908-9946, or by mail using Form 4506-C.

Getting a transcript by mail takes two to four weeks. If you need to file your taxes sooner, filing online or by phone with the IRS is faster. The IRS can also investigate why your W-2 wasn't sent — this is called a W-2 complaint — though this process is slower and is mainly useful if your employer is deliberately withholding W-2s from multiple employees.

If you lost your W-2 or need a duplicate

If you received your W-2 but lost it, the simplest solution is to ask your employer for a duplicate. Most payroll systems can print another copy when ready. Call or email payroll and ask for a duplicate W-2 for the year you need.

If your employer won't provide a duplicate or is no longer reachable, you can use the IRS wage transcript instead. The transcript shows the same wage and tax information and is accepted by tax software and tax preparers. You cannot file your taxes without either the W-2 or the transcript, so getting one of these is necessary before you proceed.

How to use your W-2 to file taxes

When you file your federal income tax return, you'll enter the information from your W-2 into tax software (like TurboTax or FreeTaxUSA), give it to a tax preparer, or fill out Form 1040 by hand. The software or preparer will ask you for your gross income, federal tax withheld, and other details from the W-2.

The IRS already has a copy of your W-2, so if the numbers you report don't match, the IRS will send you a notice. This is why accuracy matters — double-check the numbers on your W-2 before you file. If you spot an error on your W-2 (wrong Social Security number, wrong income amount, wrong tax withheld), contact your employer when ready and ask for a corrected W-2, called a W-2c.

If you worked for multiple employers, you'll enter information from all your W-2s into one tax return. The tax software will add up your total income from all employers.

Keeping records and understanding what's on your W-2

Keep your W-2 and any related tax documents for at least three years. The IRS can audit a return up to three years after you file, and you'll need your W-2 to prove the numbers you reported. If you file a claim for a refund, keep records for seven years.

Your W-2 has several boxes with different information. Box 1 shows your taxable wages. Boxes 2 and 3 show federal and Social Security tax withheld. Box 5 shows Medicare tax withheld. If you contributed to a 401(k) or traditional IRA through your employer, that amount appears in Box 12. If you had health insurance through your employer, that information may appear in Box 12 as well. Don't worry about understanding every box — tax software will guide you through which ones matter for your return.

State and local W-2 information

Your W-2 also includes state and local tax information if you live in a state or city that has income tax. Box 19 shows state income tax withheld, and Box 20 shows the state where you worked. If you worked in multiple states during the year, you may receive separate W-2s for each state, or one W-2 with information for multiple states.

When you file your state income tax return, you'll use the state information from your W-2 the same way you use the federal information. Some states allow you to file online for free, while others require you to use a tax preparer or software. Check your state's tax agency website for instructions.

Frequently Asked Questions

Can I file my taxes without my W-2?

You need either your W-2 or an IRS wage transcript to file. If you don't have your W-2, request a transcript from the IRS before you file. Filing without reporting your wages will trigger an IRS notice because the IRS has the information from your employer.

What if my W-2 has the wrong information on it?

Contact your employer's payroll department and ask them to issue a corrected W-2, called a W-2c. They'll send you the corrected form and also send a copy to the IRS. Once you receive the W-2c, use that information to file your taxes instead of the original W-2.

Do I need to keep the paper W-2 after I file my taxes?

You don't need the physical paper, but keep a copy (digital or paper) with your tax records for at least three years. If the IRS asks questions about your return, you'll need to show your W-2 to prove the numbers you reported.

What if I worked for a company that went out of business?

Request a wage transcript from the IRS using Form 4506-C or online at IRS.gov. The IRS has records of what your employer reported, even if the company no longer exists. You can use the transcript to file your taxes.

Do I need a W-2 if I'm self-employed?

No. Self-employed people don't receive W-2s. Instead, you report your income on Schedule C and pay self-employment tax. If you had both W-2 income from an employer and self-employment income, you'll file both the W-2 information and Schedule C on the same return.
