The solution for entering the Canadian zip code on a W-2 is to
1.
If you have already entered the W-2, delete it so you start fresh.
2.
When you add a new W-2, the screen will ask you for the
employer’s EIN. DON’T PUT ANYTHING HERE.
3.
Instead, just leave the EIN field blank and continue.
4.
Enter your complete W-2 information on the next page.
Make sure to indicate that this is a foreign address (under “Address Type”).
It’s OK to enter the EIN here at the top of the page.
5.
Be sure you enter everything from the W-2 – the input
screen is rather long and needs scrolling.
Done this way, the software accepts the
Canadian zip code.
