A question regarding filing tax this year. I am a US green card holder. Until June 2015 I was working in the UK. I was on Work Visa. In June 2015 I immigrated to the US. Since then I work for a company in the US. Now it is time to do my taxes. I was wondering do I need to mention my earning in the UK? If yes, do I need to pay tax on that earning?
Some notes:
I paid all of my tax to the UK (HMRC) when I was there, I don’t owe them any money. So until June 2015 when I left that country I paid all of my taxes there.
I don’t have any assets there; I just have a bank account which has less than 10GBP in it.
I obtained my green card in 2014.
Since June when I left UK I don't have a valid visa anymore.
The tax year in the UK is 6 April to 5 April. In the US it is January to January.
While I was in the UK I didn't have any earning in the US and while I was in the US I had zero earning from UK.
