Your employer must send your W2 by January 31

Your employer is required by the IRS to mail or deliver your W2 form by January 31 of the year following the one you worked. If you worked during 2024, your W2 arrives by January 31, 2025. This important date applies whether your employer sends it by mail, email, or hands it to you in person.

The January 31 date is a hard requirement, not a guideline. If your employer misses it, they face IRS penalties. That said, many employers send W2s earlier — some in mid-January, some even before the new year begins. There is no penalty for sending it early.

If you have not received your W2 by early February, contact your employer's payroll or human resources department. They can tell you whether it was mailed and to what address, or resend it when ready if there was a delay.

Key Takeaways

  • Your W2 arrives by January 31 each year for the prior calendar year's income.
  • Most employers send W2s in January, but some send them earlier in December or early January.
  • If you do not receive it by early February, contact your employer's payroll department to request a copy or confirm the mailing address.
  • The IRS also receives a copy of your W2, so you can request a transcript from the IRS if your employer cannot provide one.
  • You need your W2 to file your tax return, but you do not have to wait for it to arrive before filing if you have the information from your pay stubs.

What happens if your W2 is late

If January 31 passes and you still do not have your W2, your first step is to call or email your employer's payroll department. Provide your full name, Social Security number, and the year the W2 covers. Ask them to confirm they have your correct mailing address or offer to pick it up in person.

Many late W2s are straightforward mailed to an old address. If you moved during or after the year you worked, make sure your employer has your current address on file. Some employers will email a copy when ready if you ask, which solves the problem in minutes.

If your employer cannot or will not provide your W2, you can request a wage and income transcript directly from the IRS. The IRS has a copy of every W2 filed in your name. You can order this transcript online at irs.gov, by phone at 1-800-908-9946, or by mail. The transcript shows your reported income and tax withholding for the year.

When you need your W2 to file taxes

You need your W2 to file your federal income tax return. The form shows how much you earned, how much tax was withheld from your paychecks, and other information the IRS uses to process your return. Without it, you cannot complete an accurate return.

However, you do not have to wait for the physical W2 to arrive before you file. If you have your final pay stub from the year, it contains the same information — your year-to-date gross pay, federal tax withheld, and other deductions. You can use that information to file your return early, then update it later if the W2 shows different numbers (which is rare).

The tax filing important date is typically April 15. If you file before your W2 arrives and the numbers match your pay stub, you are done. If they differ, you may need to file an amended return, though this is uncommon.

How to read your W2 when it arrives

Your W2 is a single page with six copies — one for you, one for your state, one for your local tax authority, and three for the IRS and your records. The form is divided into boxes, each containing a specific piece of income or tax information.

Box 1 shows your taxable wages — the amount you earned that is subject to federal income tax. Box 2 shows federal income tax withheld from your paychecks. Boxes 3 and 5 show Social Security wages and tax withheld. Boxes 4 and 6 show Medicare wages and tax withheld. Your name, address, and Social Security number appear at the top, along with your employer's name and tax ID number.

Check that your name, Social Security number, and address are correct. If anything is wrong, contact your employer and ask them to file a corrected W2 (called a W2-C) with the IRS. Do not file your tax return until the information matches your records.

What to do with your W2 after you receive it

Keep your W2 in a safe place. You will need it to file your federal and state tax returns. If you file electronically, you do not mail the W2 itself — you enter the information into your tax software or give it to a tax preparer. The IRS already has a copy from your employer.

If you file by mail, you may need to attach a copy of your W2 to your return, depending on your state and the tax software you use. Check the instructions for the form you are filing to see whether an attachment is required.

Keep your W2 for at least three years after you file your return. The IRS can audit returns up to three years back, and you may need to show your W2 as proof of income if you explore for a loan, mortgage, or rental housing. Some people keep W2s for seven years or longer for their records.

Multiple W2s from different employers

If you worked for more than one employer during the year, each one will send you a separate W2. You must report all of them on your tax return. Add up the income and tax withheld from all W2s to get your total for the year.

Each employer sends their W2 by January 31, but they may not all arrive on the same day. If you are still waiting for one W2 by mid-February, contact that employer directly. Do not file your return without reporting all your W2 income — the IRS will catch the discrepancy when they match your return to the W2s they received.

Frequently Asked Questions

Can I file my taxes before my W2 arrives?

Yes, if you have your final pay stub showing year-to-date earnings and tax withheld. The pay stub contains the same information as your W2. You can file using that data, though you may need to amend your return if the W2 shows different amounts when it arrives. This is rare.

What if my W2 shows the wrong amount of income or tax withheld?

Contact your employer when ready. Ask them to review their records and file a corrected W2 (W2-C) if there is an error. Do not file your tax return until the W2 is corrected. If your employer refuses to correct it, you can file a dispute with the IRS, but correcting it with your employer first is faster.

Do I need to keep my W2 after I file my taxes?

Yes. Keep it for at least three years in case the IRS audits your return. Many people keep W2s for seven years or longer. You may also need it as proof of income for loans, mortgages, or rental housing applications.

What if my employer went out of business and I cannot get my W2?

Request a wage and income transcript from the IRS at irs.gov or by calling 1-800-908-9946. The IRS has a record of your W2 even if your employer is no longer in business. You can use the transcript to file your return.

Do I need to mail my W2 to the IRS when I file my return?

No. Your employer already sent a copy to the IRS. If you file electronically, you enter the information into your tax software. If you file by mail, check your form's instructions — some states require you to attach a copy, but the IRS does not.
