My friend who is an international student got a W-2 and a 1042-S. I worked, too, but I only got a 1042-S. Why?
Depending on the type of income you had, you will receive different forms. A W-2 lists employment income (compensation) that is not tax treaty exempt. A 1042-S lists employment income that is tax treaty exempt. So, if your employment income is tax treaty exempt and your friend's is taxable employment income, you will see that each of you will have the information reported in a different way.
When will I receive my W-2 and/or 1042-S?
The W-2 must be provided by January 31 of the new calendar year.
The 1042-S must be provided by March 15 of the new calendar year.
