A Form W-2 is more than just a piece of paper; it's one of the most important records you need at tax time. Here's what a W-2 is, how to understand what's on it and how to get your W-2.
What is a Form W-2?
IRS Form W-2, the “Wage and Tax Statement,” reports an employee’s income from the prior year, how much tax the employer withheld and other information. Employers send employees a Form W-2 in January (a copy also goes to the IRS). Employees use Form W-2 to prepare their tax returns.
Your Form W-2 tells you how much you earned from your employer in the past year and how much withholding tax you've already paid on those earnings. For many people, the information on the W-2 determines whether they’re getting a refund or writing a check at tax time.
How do I get my Form W-2?
If your W-2 for the current year doesn’t show up in the mail by Valentine’s Day, first ask your employer for a copy and make sure it’s got the right address. Your employer may also tell you how to get your W-2 online from the HR department or payroll processor. If that doesn’t fix things, call the IRS (here's a list of useful IRS phone numbers). You’ll need to provide information about when you worked and an estimate of what you were paid.
Remember that your tax return is still due by the tax-filing deadline, so if you don't have your W-2, you might need to estimate your earnings and withholdings to get it done on time. (Go here to learn more about getting an extension.) The IRS might delay processing your return — read: refund — while it tries to verify your information.
If your W-2 finally shows up after you already filed your tax return, you might need to go back and amend your tax return.
When should I receive my Form W-2?
The IRS requires employers to furnish W-2s to the government and employees by Jan. 31 or face penalties. The IRS generally defines furnish as “get it in the mail,” which means you should have yours in hand by the first week of February. Employers can also send employees their W-2s electronically, but it’s not required. That means you may be able to get yours online.
Even if you quit your job months ago, your ex-employer can still wait until Jan. 31 to send you a W-2 — unless you ask for it earlier, in which case the employer has 30 days to provide it.

How a Form W-2 works
You use the W-2 to file your tax return. Form W-2 shows more than just what you were paid. It also details how much you contributed to your retirement plan during the year, how much your employer paid for your health insurance, or even what you received in dependent care benefits. All of that data affects your tax picture — your retirement contributions might not be taxable, for example.
Box 1: Details how much you were paid in wages, tips and other compensation.
Box 2: Shows how much federal income tax was withheld from your pay.
Box 3: Shows much of your pay in Box 1 was subject to Social Security tax.
Box 4: Shows how much Social Security tax was withheld from your pay.
Box 5: Shows much of your pay in Box 1 was subject to Medicare tax.
Box 6: Shows how much Medicare tax was withheld from your pay.
Box 7: Shows how much of the tip income you reported to your employer (those tips are included in Box 1) was subject to Social Security tax.
Box 8: Shows the amount of other tips your employer allocated to you. This pay isn't included in Box 1. (Learn how to report tips on your income tax return.)
Box 10: Shows the amount of dependent care benefits your employer paid to you or incurred on your behalf. Note: Generally, anything over $5,000 ($2,500 if you're married by filing separately) is detailed in Box 1 as well. For the 2021 tax year (taxes due in April 2022), the American Rescue Plan Act permits employers to increase this amount to $10,500 ($5,200 for married filing separately).
Box 11: Generally, this box shows how much money was distributed to you during the year from your employer's deferred compensation plan.
Box 12: Here, there are four areas in which the employer can provide more detail about some or all of the pay reported in Box 1. For example, if you've contributed to your company's 401(k) plan, the amount of your contributions might show up in Box 12 with the code letter "D." There are many codes, which you can see in the IRS's W-2 instructions.
Box 13: This box indicates whether your earnings are subject to Social Security and Medicare taxes but aren't subject to federal income tax withholding, whether you participated in certain types of retirement plans, or whether you got certain kinds of sick pay.
Boxes 16-19: Show how much of your pay is subject to state income tax, how much state income tax was withheld from your pay, how much income was subject to local taxes, and how much local tax was withheld from your pay.
What to do if your W-2 is wrong
If your employer leaves out a decimal point, gets your name or a dollar amount wrong, or checks the wrong box — it happens — point out the mistake and ask for a corrected W-2. Pointing out the mistake and waiting for a new W-2 will cost you time, but here’s something that could make you feel better: The IRS might fine your employer if the error involves a dollar amount or “a significant item” in your address.
Your W-2 information is not a secret
You won't get away with anything if you just shove your W-2 in a drawer and decide not to put the information on your tax return. Employers are legally required to send copies of your W-2 to the Social Security Administration and IRS (“Copy A”) and your state and local tax authorities (“Copy 1”). You’ll probably get a terse letter and a few months’ worth of headaches from the IRS — and the state, if your state has income taxes — after they compare the income you reported on your tax return to the information your employer sent to the government.
