And this should be my husband and I. It's a joint tax filing so you are equally filing with him whether your income is $0 or not. There's a reason he's filing MFJ because he's getting more money back in returns using his spouse (you). If he's filing as MFJ this year then you don't need to do anything extra, it's a joint filing. And the joint filing your income will be $0 if you earned no income last year.
If you are guys are fling MFS this year, then you as an individual are not required to file if earned no income last year. Or you can still file with $0 income MFS, it's up to you.
