A W-2 is the tax form your employer sends you each January showing how much you earned and what taxes were withheld

The W-2 form (officially "Wage and Tax Statement") is a document your employer is required to send you by January 31st each year. It reports your total wages for the previous calendar year, the federal income tax your employer withheld from your paychecks, Social Security tax, Medicare tax, and state or local taxes if applicable. You receive a copy, your employer keeps a copy, and a copy goes to the IRS so the government can verify your income matches what you report on your tax return.

The W-2 is the foundation of filing your federal income tax return. When you file taxes, you report the wages shown on your W-2 and compare them to the total tax withheld. If too much was withheld, you get a refund. If too little was withheld, you owe the difference. You cannot file an accurate return without this form.

Key Takeaways

  • Your employer must send you a W-2 by January 31st for any year in which you earned wages from them.
  • The W-2 shows your gross wages, federal withholding, Social Security tax, Medicare tax, and any state or local taxes withheld.
  • You need the W-2 to file your federal income tax return and to verify your income to lenders or landlords.
  • If you do not receive your W-2 by early February, contact your employer's payroll department or the IRS for help locating it.

The boxes on a W-2 and what they mean

A W-2 has numbered boxes, each reporting a different piece of 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 Social Security tax withheld. Boxes 5 and 6 show Medicare wages and Medicare tax withheld.

Boxes 12 and 20 may contain additional information depending on your situation — for example, contributions to a 401(k) retirement plan, health insurance premiums paid pre-tax, or tips you reported. State and local tax information appears in boxes 18 through 20. You do not need to understand every box to file your taxes, but boxes 1 and 2 are the ones you will use most often on your return.

Who gets a W-2 and who does not

You receive a W-2 if you are a W-2 employee — someone on a company payroll who receives a regular paycheck with taxes withheld. If you worked for multiple employers in the same year, you will receive a separate W-2 from each one. You must report all of them when you file your taxes.

You do not receive a W-2 if you are self-employed or an independent contractor. Instead, you receive a 1099 form (usually a 1099-NEC or 1099-MISC) if you earned more than $600 from a client or business. Self-employed people report their income differently on their tax return and are responsible for calculating and paying their own Social Security and Medicare taxes.

When you receive your W-2 and what to do if it is missing

Your employer must mail or deliver your W-2 by January 31st. Most employers send them in late January or early February. If you have not received it by mid-February, contact your employer's payroll or human resources department directly — they can reprint it or confirm it was sent. Keep the email or note of when you asked, in case you need to prove you made the request.

If your employer cannot locate the form or refuses to send it, you can file Form 4852 (Substitute for Form W-2) with the IRS, but this requires documentation of your income and is more complicated. Before going that route, try calling your state's labor department or the IRS directly at 1-800-829-1040 — they can sometimes pressure an employer to send the form or help you reconstruct your income records.

How to use your W-2 when filing taxes

When you file your federal income tax return, you enter the wages from Box 1 of your W-2 on your Form 1040. The tax software you use (or a tax preparer) will ask you to input this information, and it will automatically carry over to the correct lines on your return. The federal withholding from Box 2 is also entered so the IRS can calculate whether you are owed a refund or owe additional tax.

You do not mail your W-2 with your return — the IRS already has a copy from your employer. However, keep your W-2 in your records for at least three years in case the IRS has questions about your return. If you are applying for a mortgage, rental housing, or a loan, lenders often ask to see your W-2 as proof of income, so having it on hand is useful.

The difference between W-2 income and other types of income

W-2 income is earned income — money you made from working as an employee. It is different from investment income (dividends, capital gains), rental income, or self-employment income, all of which are reported on different forms and taxed differently. W-2 income is also the only type of income that qualifies you to contribute to a traditional or Roth IRA, which is why it matters for retirement planning.

Because your employer withholds taxes from W-2 income before you receive your paycheck, the IRS already has a record of how much tax was taken out. This makes W-2 filing simpler than self-employment income, where you have to calculate and pay taxes yourself. If you have both W-2 income and self-employment income in the same year, you report them on separate parts of your tax return.

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 withheld — contact your employer immediately. They can issue a corrected W-2 (marked as a corrected return) and send it to you and the IRS. This must happen before you file your taxes, so do not wait.

If you discover an error after you have already filed your return, you will need to file an amended return (Form 1040-X) to correct it. This is more work and may delay any refund you are owed, so catching errors early is important. Always review your W-2 carefully against your final paystub from December to make sure the numbers match.

Frequently Asked Questions

What if I lost my W-2?

Contact your employer and ask for a duplicate copy — they are required to provide one. If your employer is no longer in business or unreachable, call the IRS at 1-800-829-1040 and explain the situation. The IRS can sometimes retrieve a copy of the W-2 they received from your employer, or they can help you file your return without it.

Do I need to report my W-2 if I did not owe taxes?

It depends on how much you earned. The IRS sets a minimum income threshold each year below which you do not have to file. However, if your employer withheld any federal income tax, you should file anyway to get a refund of that money. Check the IRS website for the current year's threshold based on your age and filing status.

Can my employer refuse to give me a W-2?

No. Federal law requires employers to issue a W-2 to every employee who earned wages during the year. If your employer refuses, you can report them to your state's labor department or the IRS. This is considered wage theft in many states and can result in penalties against the employer.

What happens if my W-2 shows more income than I actually earned?

Contact your employer immediately and ask them to issue a corrected W-2. Do not file your tax return using the incorrect amount. If you file first and then discover the error, you will need to file an amended return, which takes longer and may delay your refund.

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

No. Your pay stub shows your earnings and deductions for a single paycheck. Your W-2 is an annual summary of all your wages and all taxes withheld for the entire year. You receive a pay stub with each paycheck, but you receive a W-2 only once per year, in January.
