Remittance Basis / Non-US person / Capital gain tax when selling US stocks?

I've been living in the UK in the past 2 years (non-domiciled). Before that, I've been living in the US for a few years and do not have citizenship/green-card.

Right now I still have some individual US stocks in a US broker - purchased when I was in the US.

So if I sell these stocks and won't transfer the fund into the UK - while filing my UK tax on remittance basis - am I subject to paying any capital gain tax?

I don’t know the answer on UK remittance taxation but since you are domiciled in the USA I guess you are subject to US capital gain taxes along with US taxes on all worldwide income?

No, I am not domiciled in the USA as I'm not a US citizen nor am I holding a greencard.

I *think* this applies to me: "Nonresident aliens are subject to no U.S. capital gains tax, and no money will be withheld by the brokerage firm" (quoted from investopedia).

Where are you domiciled? I think you have to be domiciled somewhere since being domiciled is the place where you have most family and financial ties. Not having a domicile in any country sounds not right to me.

When you follow the residency “tests” in the document below which tests qualify you for not being resident in the UK for tax purposes?

Sorry for the confusion here. Just to confirm:
- I'm domiciled in Singapore
- I'm currently working in the UK and paying UK tax. However as I'm not domiciled in the UK, I may not have to pay UK tax on foreign income if I file tax on remittance basis

Gotcha, that all makes sense now. You had only mentioned the USA and UK 

However, I don’t know how remittance tax works but am interested in seeing the replies.
