How do I get copies of my W-2's? I moved and the employer's don't have current address. Would like to find web site to get them off line.

First I don't know of any employor that posts them online, I guess if they do, they will have to give you a passcode and user name to get onto their web site.

If you move, first your mail will be forwarded ( assuming you put in a change of address which you are suppose to do)
If not, you call them up and give you the correct addresss.

Most business do not have them available yet.

So basically call the place where you work and have them mail them to you, they are not available online

Fr. Chuck:

The U.S. government puts the W-2s online for ALL of its employees, as well as all of the military. It IS password-protected, of course.

But your other advice of calling and giving them your current address is GOLDEN.
