I lost one of my W2 forms from an employer. How can I file without that form? What does "EMP NUM" mean?

What does "EMP NUM" mean?

 

This likely means "employee number".

 

You may be able to import the W-2 from your employer, but you generally need information from the form to access the W-2 import.

 

You may have to contact your employer for a copy.
