A W2 is a document your employer sends you each January showing how much you earned and what taxes were withheld

The W2 form (officially Form W-2, Wage and Tax Statement) is a record of your wages and the federal, state, and local taxes your employer took out of your paychecks during the previous year. Your employer is required by law to send you a copy by January 31st. You use this form to file your income tax return with the IRS.

The W2 is not a bill or a payment. It is a summary document. It tells the IRS how much money you made and how much tax was already paid on your behalf. If too much tax was withheld, you get a refund. If too little was withheld, you owe the difference.

You will receive a W2 if you worked as an employee for a company, nonprofit, government agency, or other employer that withheld taxes from your paycheck. You will not receive a W2 if you were self-employed, worked as an independent contractor, or earned income another way.

Key Takeaways

  • Your employer must send you a W2 by January 31st each year, showing your total wages and all taxes withheld.
  • The W2 lists federal income tax, Social Security tax, Medicare tax, and sometimes state and local taxes withheld from your pay.
  • You need the W2 to file your federal income tax return; the IRS receives a copy from your employer too.
  • If you worked for more than one employer in a year, you will receive a separate W2 from each one.

The boxes on your W2 and what they mean

A W2 has numbered boxes, each showing a different piece of information about your income and taxes. The most important ones are:

Box 1 (Wages, tips, other compensation): This is the total amount of money you earned before any taxes or deductions were taken out. This is the number you use to calculate your income tax.

Box 2 (Federal income tax withheld): This is the federal income tax your employer took out of your paychecks. This amount is already paid to the IRS on your behalf.

Boxes 4 and 6 (Social Security and Medicare taxes): These show the Social Security and Medicare taxes (also called FICA taxes) that were withheld. These are separate from federal income tax.

Boxes 16–20 (State and local taxes): If you live in a state or city that has income tax, these boxes show what was withheld for those taxes. Not all states have income tax, so these boxes may be blank.

Box 12: This shows other deductions or benefits, such as health insurance premiums, 401(k) contributions, or dependent care expenses. The letter code next to the amount tells you what type of deduction it is.

When you receive your W2 and what to do with it

Your employer must mail you a W2 by January 31st of the year after you worked. You should receive it at the address on file with your employer. If you move during the year, update your address with your employer so the W2 reaches you.

Keep your W2 in a safe place. You will need it to file your income tax return. If you file electronically, you can enter the information from your W2 into tax software or give it to a tax preparer. If you file on paper, you attach a copy of the W2 to your return.

The IRS also receives a copy of your W2 directly from your employer. The IRS uses this to check that the income and taxes you report on your return match what your employer reported.

What to do if you do not receive your W2

If January 31st has passed and you have not received your W2, contact your employer's payroll or human resources department. Give them your current mailing address and ask them to send it again or provide it electronically.

If your employer will not send you a W2 or has gone out of business, 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 other documentation of what you earned. You will need to gather this information yourself.

Do not file your tax return without a W2 or a substitute unless you have already tried to get the W2 from your employer. The IRS may contact you later if the numbers do not match.

W2 versus other income forms

Different types of income require different forms. If you were an employee and earned wages, you receive a W2. If you were self-employed or worked as an independent contractor, you receive a 1099-NEC (Nonemployee Compensation) or 1099-MISC (Miscellaneous Income) instead. These forms show income but do not show taxes withheld, because self-employed people pay their own taxes.

If you earned interest from a bank account, dividends from investments, or income from rental property, you receive different 1099 forms for each type. Each form goes to a different line on your tax return.

If you received unemployment benefits, you get a 1099-G. If you received a refund of state income tax, you also get a 1099-G. These are reported separately on your return.

Multiple W2s in one year

If you worked for more than one employer during the same year, you will receive a separate W2 from each employer. When you file your tax return, you report the income and taxes from all of your W2s together.

Add up the wages from all your W2s to get your total income for the year. Add up all the federal income tax withheld from all your W2s to see how much tax was already paid. The IRS will check this total against what each employer reported.

Having multiple W2s does not complicate your taxes significantly, but it does mean you need to keep track of all of them and make sure you have them before you file.

Frequently Asked Questions

What if the information on my W2 is wrong?

Contact your employer immediately and ask them to issue a corrected W2, called a W2-c. Your employer must send you the corrected form and file it with the IRS. Do not file your tax return until you have the corrected W2, because the IRS will see a mismatch between what you report and what your employer reported.

Do I need to send my W2 to the IRS?

No. Your employer sends a copy directly to the IRS. You keep your copy for your records and use it to file your return. You do not mail your W2 to the IRS unless you are filing on paper and your tax software or preparer tells you to attach it.

Can I file my taxes without a W2?

You should not file without one. If you have not received your W2 by early February, contact your employer. If they will not provide it, you can file Form 4852 as a substitute, but this may delay your refund or trigger an IRS inquiry.

What happens if my employer does not send me a W2?

This is a violation of federal law. Report it to the IRS using Form 13909 (Information Referral). You can also contact your state's labor department. In the meantime, gather your own records — pay stubs, bank deposits, or emails about your pay — and file Form 4852 to report your income.

Is the W2 the same as my pay stub?

No. Your pay stub shows what you earned and what was withheld in a single paycheck. Your W2 shows the total for the entire year. You receive a pay stub with each paycheck; you receive a W2 once per year.
