federal是合报的 LD加州全年有收入 偶加州8个月无收入，后离开加州～ 报加州州税可以jointly吗？用540吗？（可是偶是part-year，能跟ld 用540吗？ 还是应该分开，ld自己用540，偶不报税（因为没有收入）
你应该是选择和联邦税filing status一致。。。 合报的话则你们俩人要用540NR；分开报的话，也可以的话貌似不行，请参考加州的Form 540 Instruction:
以下是instruction excerpt ==》 https://www.ftb.ca.gov/forms/2015/15_540ins.pdf
If you file a joint tax return for federal, you may file separately for California if either spouse was:
• An active member of the United States armed forces or any auxiliary military branch during 2015.
• A nonresident for the entire year and had no income from California sources during 2015.
If you filed a joint tax return and either you or your spouse/RDP was a nonresident for 2015, you must file the Long or Short Form 540NR, California Nonresident or Part-Year Resident Income Tax Return.
