If you can’t get your Form W-2 from your employer and you previously attached it to your paper tax return, you can order a copy of the entire return from the IRS for a fee. Complete and mail Form 4506, Request for Copy of Tax Return along with the required fee. Allow 75 calendar days for us to process your request.

You cannot get your W-2 online. You get a W-2 from your employer. Or you can pay the Social Security Administration $86 for it if it is for a previous year. Or you can get a wage and income transcript from the IRS that will show wages reported by an employer to the IRS.
