We lived separately for entire year. So one is a resident of CA, another one is resident of MA.
California requires MFJ. But MA allows MFS in that case. We can create a MFS for MA as described in another article (via mock federal MFS).
MA return requires federal AGI - I can edit it on the form and add one from federal MFJ, correct?
How to file so that there's no double taxation in CA? Shall I attach MA return to CA?
