I live and work in the US on H1B visa with recent spouse on H4. I filed my 2012 state and federal return along with spouse's w7 forms and document copies as per filing instructions but never got anything back from IRS about the ITIN or the return. I did hear back from state(MD) that my wife's ITIN has been denied by IRS and they cannot give me tax exemption for married status (if I am decoding their letter correctly), they sent me refund as per single status. I've seen some similar unfortunate threads, I want to make sure I get my federal refund back this year (my w4 is still per single status). I have looked up IRS tax payer advocate but I don't know if they can help.
Is there anyway I can get my state and federal refund for 2012?
Has anyone been through something similar with IRS and ITINs?
Update: After getting passport copies certified by local IRS office and filing W7 along with return, I finally got 2013 and 2012 refund back in full.
Is it advisable to attempt take IRS to court on this, if at all possible?
