How a green card holder with earning in the US and overseas in a single tax year file a tax return?

Hi all,

 

Background of my case:

I am a green card holder, and worked as a postdoc at Harvard in MA since year 2020. I used to file Federal and MA state tax electronically, using the free version of turbox tax online, and the returned money was deposited directly to my US bank account.

 

Then I got a job to work in Hong Kong (My hometown, I am a Hong Kong citizen). I officially quitted working at Harvard on May 31, 2023, and started my job in Hong Kong on July 3, 2023.

 

So in summary:

- For the tax year 2023, I lived in and earned for 5 months at Harvard Medical School, MA, U.S, and then 6 months of earning in Hong Kong.

 

I understand that I need to pay US tax for the earning at Harvard and my earning in Hong Kong.


Questions:
1) Now I am in Hong Kong. Can I do Federal and MA state tax return with Turbox tax online and file electronically? If yes, which version is suitable for me?

 

2) For my income in Hong Kong, will I able to use Foreign Earned Income Exclusion, possibly also housing exclusion and foreign tax credit with Turbox tax online?

 

3) I am paying housing mortgage for an apartment in Hong Kong, and also supporting >50% of the living fee of my mother and father in Hong Kong, will I have tax deduction because of them?

 

4) My wife is a Hong Kong citizen only, she has no ITIN, and has been working in Hong Kong for over 15 years. Her salary income is about 100 000 USD/year. Can I file a joint tax return with her using turbox online, and if yes, will that likely lower my tax payment?

 

Best,

Jake
