What is a W-2?

A W-2 is a tax form that summarizes an employee’s income from the prior year and how much tax was withheld. Employers send W-2s to employees and the IRS by the end of January.

A W-2 is a tax form that summarizes an employee’s income from the prior year and how much tax was withheld. Employers send W-2s to employees and the IRS by the end of January.

You should receive a W-2 from every employer that paid you at least $600 during the year. Freelancers or independent contract workers who do not have taxes withheld by an employer get 1099s from their clients, not W-2s.

Understanding your W-2 form

Understanding your W-2 form

You use the W-2 to help file your tax return. Form W-2 also shows more than just what you were paid. It details how much you contributed to your retirement plan during the year, how much your employer paid for your health insurance, or what you received in dependent care benefits. All of that data affects your tax picture.

It details how much you contributed to your retirement plan during the year, how much your employer paid for your health insurance, or what you received in dependent care benefits. All of that data affects your tax picture.

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”). The IRS — and the state, if your state has income taxes — will compare the income you reported on your tax return to the information your employer sent to the government.

How to get your W-2

How to get your W-2

Your W-2 form should be mailed to you by early February. If it doesn't show up, ask your employer for a copy and make sure it has the right address. Your employer may also tell you how to get your W-2 online from the HR department or payroll processor.

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 file for tax extension or estimate your earnings and withholdings to get it done on time. 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 with a Form 1040-X.
