One more question: In the joint federal tax return, I use Form 8843 as evidence to state my F1 status since I am a student, and use Form 8833 to claim my tax-treaty exemption. Form 8843 and 8833 should be mailed with my federal tax return. For the joint CA state tax, do I still need to attach Form 8833 with the copy of Form 1040? And do I need to attach Form 8843 when mailing the joint CA state tax?
In case you miss my last reply:
Column E is California source income. You didn’t mention who is claiming the treaty exemption. It would be $0 if it is from Illinois income and unchanged if from CA income.
Only me is claiming the US-China tax treaty since I am a student and hence I am still satisfied with the exception of the saving clause of the US-China tax treaty. For clarification, let me say it in my way: for example, the original CA amount is all the income earned by my wife when she is a (part year) resident in CA, which is $A. And my tax treaty exemption from Illinois is $B. Then after we report the tax treaty exemption in our joint CA state tax return (i.e., added them back in line 1 Column C), the line 1 Column E should still be $A since the $B is not CA source income. Is it correct?
