Your W2 arrives by January 31 each year, mailed by your employer

Your employer must send you a W2 form by January 31 of the year following the one you worked. This is a federal requirement. The form shows your total wages for the previous calendar year and the taxes withheld from your paychecks. Your employer mails it to the address they have on file — usually your home address.

If you worked for multiple employers during the year, each one sends a separate W2. If you changed addresses during the year, the W2 may go to an old address. The IRS also receives a copy, so the government knows what your employer reported about your income.

The timing matters because you need the W2 to file your tax return. Most people file between February and April, so receiving the form by the end of January gives you time to gather documents and file before the April 15 deadline.

Key Takeaways

  • Your employer must mail your W2 by January 31, but you may receive it a few days later depending on mail speed.
  • If you do not have your W2 by mid-February, contact your employer's payroll department directly — they can reprint it or send it electronically.
  • You can file your tax return using IRS Form 4852 if your W2 is lost or your employer will not provide one, though this takes longer to process.
  • The IRS has a record of what your employer reported, so filing without a W2 does not hide income — it just delays your refund.

What happens if your W2 is late or never arrives

If January 31 passes and you do not have your W2, start by calling your employer's payroll or human resources department. Give them your name, Social Security number, and the year you worked. They can print a copy immediately or email it to you. Most employers keep records for at least seven years, so even if you left the job years ago, they can usually retrieve it.

If your employer is out of business, closed, or will not respond, you have another option. You can file your tax return using IRS Form 4852, which is a substitute for a missing W2. You fill in the income and tax withholding amounts based on your own records — pay stubs, bank deposits, or anything that shows what you earned. The IRS will compare this to what your employer reported and contact you if there is a discrepancy.

Filing with Form 4852 takes longer to process than filing with an actual W2. The IRS may send you a notice asking for proof of your income. Keep copies of any documents you used to complete the form.

Corrected W2s (Form W2-C) and what they mean

Sometimes your employer discovers a mistake after sending your W2 — wrong Social Security number, wrong income amount, or wrong tax withholding. When this happens, they send you a corrected W2, officially called Form W2-C. This replaces the original W2. You should use the corrected version when you file your tax return.

Corrected W2s can arrive anytime during tax season, even in March or April. If you already filed your return using the original W2 and then receive a corrected one, you will need to file an amended return using Form 1040-X. This is not complicated, but it does mean your refund or payment may change.

How to find your W2 if you lost the paper copy

If you threw away your W2 or cannot find it, you have several ways to get the information without waiting for a replacement. Many employers let you log into a payroll portal or employee benefits website and download your W2 as a PDF. Check any email from your employer's payroll department — they often send a link to access it online.

You can also call the IRS at 1-800-829-1040 and request a transcript of your tax return from the previous year. This transcript includes the W2 information the IRS received from your employer. The IRS can mail it or, in some cases, provide it over the phone. There is no charge for this.

If you need the information right away to file your return, use your own records. Your last pay stub of the year usually shows year-to-date totals for income and withholding — these are the same numbers that appear on your W2.

W2 timing for seasonal or temporary work

If you worked a seasonal job or a short-term contract, your employer still must send a W2 by January 31 if you earned any wages that year. The amount does not matter — even if you earned $100, you get a W2.

Temporary staffing agencies and day labor companies also send W2s. If you worked through multiple agencies, each one sends its own W2 for the income they paid you. You will report all of them on your tax return.

What to do if your W2 shows the wrong information

If your W2 has errors — wrong income amount, wrong tax withholding, wrong name or Social Security number — contact your employer immediately. Do not file your tax return with wrong information. Your employer can issue a corrected W2 (Form W2-C) before you file.

If you already filed and then discovered the error, you can file an amended return. But it is faster and simpler to get the correction before filing in the first place. Keep records of any communication with your employer about the error — emails, phone call notes, or letters.

Frequently Asked Questions

Can I file my tax return before I receive my W2?

No. You need your W2 to file an accurate return. If you file before receiving it and the information does not match what your employer reported, the IRS will contact you and you will have to file an amended return. It is better to wait for the W2.

What if my employer says they already mailed my W2 but I never got it?

Ask your employer to confirm the mailing address they used. If it was wrong, ask them to mail a new copy to the correct address or email it to you. If the address was correct, the mail may have been delayed or lost. Give it another week, then contact your employer again.

Do I need to keep my W2 after I file my tax return?

Yes. Keep it for at least three years in case the IRS asks questions about your return. The IRS can audit returns going back three to seven years depending on the situation. Store it with your tax documents.

What if I worked but my employer never sent me a W2?

Contact your employer's payroll department and ask for it. If they refuse or claim you were not an employee, you can file Form 4852 with the IRS and report the income yourself. The IRS has a record of what your employer reported, so they will know if there is a mismatch.

Can I get my W2 electronically instead of by mail?

Many employers offer this. Ask your payroll department if they can email your W2 or post it to an employee portal. Some employers require you to opt in to electronic delivery, so check your employee benefits website or ask during onboarding.
