State return efile when applying ITIN with federal return

[rico_co]

I’m applying ITIN for my spouse using W7 with the federal return. She is not eligible for SSN but I’m including her as jointly filed tax return. I understand I need to file by mail for the federal return with W7 form, but can I write “applied for” in state return, and still do efile for state? Or do I need to file state return by mail as well?

Your state return cannot be e-filed if you filed federal by mail.   You will need to file state by mail too.
