I am not a US
Citizen/Green Card holder who was working in the U.S. on H1B Visa from Jan-July 2015. I departed the U.S. in Aug 2015 to take up employment overseas and have not returned since. I did not earn any US based income
since my departure.
I'm trying to complete my 2015 US tax returns
and because I was present for more than 183 days in the U.S., which makes me a Resident Alien
purposes and subject to be taxed on world wide income.
I understand if I do not wish to be taxed on my overseas income after I departed the U.S. (from Aug-Dec 2015), I need to submit a dual status return
? Is this Correct?
If this is correct, I've read I need to file a 1040NR and also a 1040 as a statement? What is meant by 1040 statement? Do I declare my world wide income when I was a resident alien on the 1040 (from Jan-July) and only US income when I was a non-resident alien on the 1040NR (which would be zero).
Or do I declare my total U.S. based income for the whole year on the 1040NR and the total worldwide income from when I was a resident alien on the 1040. if I did not earn any non-US income during the time I was non-resident alien, then the income on both forms
would be the same?
Do I need to complete any other portions of the 1040 other than the income portion? Do I take all my deductions
on the 1040 NR?
Do I also need to attach a statement of residency termination to declare the date that I want to terminate my residency (i.e. Aug 2015) if i don't include it, I've read that it would automatically be assumed to be Dec 2015 and in which case would that mean I need to pay my world wide income for the entire year? What information/format should this statement be?
