W2s must be mailed by January 31 each year, but many employers send them earlier

W2 forms are due to arrive by January 31 of the year following the one you worked. Your employer is required by the IRS to mail them by that date, though many send them in late December or early January. If you work for multiple employers, each one sends their own W2 separately — you'll receive one from each company you worked for during the year.

The January 31 deadline is a legal requirement, not a suggestion. Employers who miss it face penalties. That said, the deadline applies to when the form is mailed, not when it reaches your mailbox. Delivery can take a few days to a week depending on your location and mail speed.

Some employers offer electronic delivery through a secure portal or email instead of paper mail. If your employer provides this option, you may see your W2 available online before it arrives in the mail. Check your employer's HR or payroll website or any emails from your company in late December and early January.

Key Takeaways

  • W2s must be mailed by January 31, though many employers send them in December or early January.
  • Each employer you worked for sends a separate W2 — if you had multiple jobs, expect multiple forms.
  • Some employers post W2s to an online portal before mailing paper copies, so check your company email and HR website.
  • If your W2 hasn't arrived by mid-February, contact your employer's payroll department directly.
  • The IRS has a tool to track W2s that haven't been received, and you can file your tax return without the form if necessary.

Why the January 31 deadline matters for your taxes

The January 31 deadline exists because tax season begins February 1 in most years. The IRS wants employers to send W2s to workers before filing season opens so you have the information you need to file. If you're planning to file early, you'll need your W2 in hand.

However, you don't have to wait for your W2 to file. The IRS allows you to file using an estimate of your income if your W2 is delayed. You can then file an amended return once the actual W2 arrives. Many tax software programs and tax preparers can handle this process, though it adds an extra step.

What to do if your W2 is late

If February 15 has passed and you still don't have your W2, contact your employer's payroll or HR department. Call or email and ask directly — don't assume it's lost. Many late W2s are simply delayed in the mail or held up in a company's processing queue.

Give your employer a reasonable window to respond, usually a few business days. Ask them to confirm they have your correct mailing address on file. If the address is wrong, they may need to remail it. Request a copy be sent to you electronically if possible, or ask them to provide the information over the phone so you can note it down.

If your employer doesn't respond or claims they never sent it, you can file Form 4852 (Substitute for Form W-2) with the IRS. This form lets you report your income based on your own records — pay stubs, bank deposits, or 1099s if you also did contract work. You'll need to gather documentation of what you earned.

Using the IRS W2 lookup tool

The IRS maintains a system that tracks W2s filed by employers. If you believe your employer filed your W2 but you never received it, you can contact the IRS at 1-800-829-1040 to request a transcript or to report that your W2 hasn't arrived. Have your Social Security number, employer name, and the year in question ready.

The IRS can tell you whether your employer actually filed your W2 with them. If it was filed, the IRS has a record of your income and can provide you with that information. If it wasn't filed, that's a separate problem — your employer failed to file, and you'll need to follow up with them or file Form 4852.

Multiple W2s and keeping track of them all

If you worked for more than one employer during the year, you'll receive a W2 from each one. They don't all arrive on the same day. Some employers mail early; others wait until late January. Keep a list of where you worked and check your mail regularly through early February so you don't miss any of them.

When you file your tax return, you'll need to report income from all your W2s. Tax software typically walks you through entering each one. If you're missing a W2 from one employer but have the others, you can still file — just note that one is missing and file an amended return once it arrives.

If you left a job mid-year

If you quit or were laid off partway through the year, your employer still sends you a W2 for the time you worked there. It will show only the income and taxes from the months you were employed. You'll receive it by January 31 just like any other W2.

If you were fired or laid off and your employer is being difficult about sending your W2, that's still a legal requirement they must meet. Contact your state's labor department or the IRS if the employer refuses. Don't let a bad separation prevent you from getting the form you're owed.

Frequently Asked Questions

Can I file my taxes before I get my W2?

Yes. You can file using an estimate of your income based on your pay stubs or last year's W2. Once your actual W2 arrives, you can file an amended return if the numbers differ. Many people do this in early February rather than wait until late January.

What if my employer went out of business?

Contact the IRS at 1-800-829-1040 and explain the situation. They can help you obtain a transcript of your earnings for that year, which you can use in place of a W2. You may also need to file Form 4852 if no transcript is available.

Do I need to do anything if I get my W2 electronically?

No. An electronic W2 is legally the same as a paper one. Download and save it, then enter the information into your tax return or give it to your tax preparer. You don't need to print it unless you want a paper copy for your records.

What if the W2 has wrong information on it?

Contact your employer immediately and ask them to issue a corrected W2, called a W2-c. They must send the corrected form to you and the IRS. Don't file your taxes with incorrect information — get it fixed first.

How long do I need to keep my W2?

Keep your W2 for at least three years in case the IRS audits your return. Many people keep them longer for their own records. Store them in a safe place with your other tax documents.
