L1 Visa Holder - First Time Filing - Queries
I moved to the US on 14th Nov 2006 to work under a L1 visa. My salaries are paid by the local offices of my parent company in dollars. I got my W2 form from my employer and need to file my tax. I have my family with me since I came - wife and two kids (3 yrs and 1 yr+), but none of them have an SSN or a ITIN. They are on L2 visa. Wife does not work.
In the W2 form, my marital status has been taken as Single. I understand that I can claim some refund since I support from my family. I don't have any other sources of income. I am in the state of Kentucky.
My queries:
1. What forms do I need to fill to file my tax?
2. Is it necessary to get a SSN/ITIN for my wife and kids to claim some relief or exemption since they are completely dependent on me?
3. Is it advisable to file jointly or separately in my situation?
4. Can I file through efile on IRS.gov - I am asking this because I signed up there but I don't see any place where it helps file under a category like resident alien which would apply to me.
5. What is the last date for me to file? If I need to file with SSN for my dependents, and it is going to take 4-5 weeks, can I take some extension and how?
Thanks!
