Hi, have recently retired and am now based in Thailand.  Am just wondering if in the future I realized a capital gain from the sale of shares in a private company (purchased before coming to Thailand) am I potentially liable to capital gains tax in Thailand as a retiree living here once the overseas shares are sold?  I would not expect to bring the realized gain into Thailand in the year it was made.  Thanks. 

For background, what is your country of citizenship?  Legal residence?   And....where is the private company domiciled and would the gain on the sale of your shares be taxed there?  

Thailand doesn't want to know what capital gains you make outside Thailand.

I am a UK citizen and a permanent Hong Kong ID card holder so I have the right of abode to live and work there.   Am non resident in the UK for tax purposes and the shares were purchased whilst in Hong Kong.  The private company is UK domiciled although as I am not tax resident in the UK I don’t envisage any UK tax liability on any realization as long as I am still non resident in the UK.   Have now relocated to Thailand on a retirement visa. 

Thank you for clarifying. 

I think not

Thank you. 

You might just want to check whether you would be liable to capital gains tax in Hong Kong, though.
