What Is a W2 Form?
A W2 form is the "Wage and Tax Statement" your employer sends after the year ends. It reports how much you earned and how much was withheld for federal, state, Social Security, and Medicare taxes. Employers give one to every employee paid $600 or more, and they send a copy to the Social Security Administration.
So what is a W2 in plain terms? It's your official year-end summary of pay and tax. If you've ever wondered what is W2 short for, "W2" is simply the IRS's shorthand for this one document, which it prints as Form W-2. People write it as W2 or "W2s" when they mean more than one. You don't mail the W2 to the IRS on your own. Your employer files it, and you attach your copy to your tax return. Employees on a payroll get a W2; independent contractors get a 1099 instead.
