I came to US on March 18th 2006 and I started working in my company which is located in NY. I stayed in NY state till July 4th (i.e for 109 days) and moved to NJ on July 5th 2006. I was single by then. I got married on Aug 10th 2006. My wife came to US on Oct 11th 2006. My stay in NJ state for the year 2006 is 180 days (July 5th - Dec 31 2006). My source of income is from NY state all the time. I am going to file as Married filing jointly with no dependents. Now, could you please tell me what I have to do for filing my state taxes. Also, please clarify the following:
1. I understand that I have to file for both state, NY and NJ. Please clarify the resident, part year resident and non-resident stuff for my case. Also, tell me the form numbers.
2. Should I file as 'single' for NY state tax?
3. My employer withheld local tax for NY? Can I claim for refund?
4. I have filed my federal tax for 2006 along with W-7 for my wife' ITIN. How do I file my NY and NJ state tax return without having my wife' ITIN? What is the procedure followed in this case?
