Hi Everyone! Can someone please let me know if I need to file CA state taxes if I am on a re-entry permit? I got my green card last year, 2011 (DV lottery). I have since been 3 times to the US for a few days (activate green card, file for re-entry permit and go for biometrics). I have received my re-entry permit valid as of January 2012. I am now about to file my US federal taxes. These are not easy to get through but with the "foreign earned income credit" or something like this, my US federal tax liability is zero. Note that I have not worked a day in the US and my address in the US is in California. My question is this: do I need to also file California state taxes besides the federal tax return? I have not worked in CA and I have spent there just a few days last year. Thank you for your help!
