The W-2 is a tax document your employer sends you showing how much you earned and what taxes were withheld

A W-2 form is an official record of your wages, salary, and taxes paid during a calendar year. Your employer is required by the IRS to send you one by January 31st each year if you earned $600 or more. The form shows your gross income (total pay before deductions), federal income tax withheld, Social Security tax withheld, Medicare tax withheld, and other information the IRS uses to match against your tax return.

You receive a W-2 because you are classified as an employee, not an independent contractor. The employer withholds taxes from your paychecks throughout the year and reports those withholdings to the IRS on your behalf. The W-2 is your proof of what was withheld, and you use it to file your federal income tax return.

The form itself is titled "Wage and Tax Statement" and comes in multiple copies. You keep one copy for your records, one goes to the IRS, one goes to your state tax authority (if applicable), and one goes to your local tax authority (if applicable). Your employer keeps a copy as well.

Key Takeaways

  • Your employer must send you a W-2 by January 31st if you earned $600 or more during the previous calendar year.
  • The W-2 shows your total wages, federal income tax withheld, Social Security tax, Medicare tax, and other deductions your employer made.
  • You need your W-2 to file your federal income tax return with the IRS.
  • If you worked for multiple employers in one year, you will receive a separate W-2 from each one, and you must report all of them on your tax return.

The boxes on your W-2 and what they mean

A W-2 has numbered boxes, each containing specific information. Box 1 shows your taxable wages — the amount subject to federal income tax. Box 2 shows federal income tax withheld from your paychecks. Boxes 3 and 5 show Social Security wages and Social Security tax withheld. Boxes 5 and 6 show Medicare wages and Medicare tax withheld.

Box 12 contains codes and amounts for special items like contributions to a 401(k), health insurance premiums, or dependent care accounts. Box 14 is for state income tax information. Boxes 15 through 20 contain state and local tax details if you lived or worked in a state or locality that collects income tax.

You do not need to understand every box to file your taxes. The most important boxes for your federal return are Box 1 (wages), Box 2 (federal tax withheld), Box 5 (Medicare wages), and Box 6 (Medicare tax withheld). Your tax software or tax preparer will know which boxes to use.

When and how you receive your W-2

Your employer must mail or deliver your W-2 by January 31st of the year following the year you worked. If you worked in 2024, you receive your W-2 by January 31, 2025. Some employers send W-2s electronically through a secure portal; others mail paper copies. Check with your employer's payroll or human resources department to find out how they distribute them.

If you do not receive your W-2 by early February, contact your employer's payroll department. If your employer has closed or gone out of business, you can file Form 4852 (Substitute for Form W-2) with the IRS, though this requires documentation of your wages and taxes paid.

If you change jobs during the year, you will receive a W-2 from each employer showing only the wages and taxes for the time you worked there. You must report all W-2s on your tax return.

W-2 versus 1099 and other income forms

A W-2 is for employees. If you are self-employed or work as an independent contractor, you receive a 1099-NEC (for non-employee compensation) or 1099-MISC (for miscellaneous income) instead. A 1099 shows income paid to you but does not show taxes withheld, because independent contractors are responsible for paying their own taxes.

If you have investment income, you may receive a 1099-INT (interest income), 1099-DIV (dividend income), or other 1099 variants. If you received unemployment benefits, you receive a 1099-G. Each form reports a different type of income to the IRS.

The key difference: a W-2 means your employer withheld taxes for you. A 1099 means you received income but no taxes were withheld, and you owe taxes on that income when you file.

What to do with your W-2

Keep your W-2 in a safe place for at least three years. The IRS can audit tax returns up to three years after filing, and you may need to show your W-2 as proof of income and taxes paid. If you file electronically, you do not need to mail your W-2 to the IRS — your tax software will transmit the information directly. If you file by mail, you do not send your W-2 either; you keep it for your records.

You will need your W-2 information to file your federal income tax return. If you use tax software, you enter the numbers from your W-2 into the program. If you use a tax preparer, bring your W-2 with you. If you received a W-2 in error (for example, you were a contractor, not an employee), contact your employer to request a corrected form or a 1099 instead.

Some employers also use W-2 information for other purposes. If you are applying for a mortgage, a rental lease, or a loan, you may be asked to provide a copy of your W-2 as proof of income. You can request additional copies from your employer's payroll department.

Correcting errors on your W-2

If your W-2 contains an error — wrong name, wrong Social Security number, wrong wage amount, or wrong tax withholding — contact your employer immediately. Your employer can issue a corrected W-2, called a W-2c (Corrected Wage and Tax Statement). You should receive the corrected form before you file your tax return if possible.

If you discover an error after you have already filed your return, you can file an amended return using Form 1040-X. This tells the IRS that your original return contained incorrect information. Keep copies of both your original W-2 and the corrected W-2 for your records.

Frequently Asked Questions

Do I need a W-2 to file taxes?

If you earned wages as an employee, yes — you need your W-2 to file an accurate federal income tax return. The IRS receives a copy of your W-2 from your employer, and your return must match that information. If you have no W-2 and no other income, you may not be required to file, but filing may result in a refund of taxes withheld.

What if I worked for two employers in one year?

You will receive a W-2 from each employer. Report all W-2s on your tax return. Your total income is the sum of all wages shown on all your W-2s. You must include every W-2 you receive, or the IRS will notice the discrepancy when it compares your return to the copies employers sent in.

Can I file taxes without receiving my W-2?

You can file using Form 4852 (Substitute for Form W-2) if your employer fails to send you a W-2 by mid-February and does not respond to your requests. You will need to estimate your wages and taxes based on your pay stubs or other records. This is not ideal and may trigger an IRS review, so exhaust all efforts to obtain your actual W-2 first.

Is the W-2 the same as a pay stub?

No. A pay stub is issued with each paycheck and shows your gross pay, deductions, and net pay for that specific pay period. A W-2 is issued once per year and shows your total wages and total taxes withheld for the entire year. You use pay stubs to verify your paychecks are correct; you use your W-2 to file taxes.

What happens if my employer does not send me a W-2?

Contact your employer's payroll department in writing and request it. If they do not respond by mid-February, you can file a complaint with the IRS using Form 13909 (Information Referral). You can also contact your state labor department. In the meantime, gather your pay stubs and prepare to file using Form 4852 if necessary.
