I have been living in ireland and whilst there I invested in the stock market using degiro, and my irish bank account for deposits and withdraws. I have been told if I get degiro to pay my withdraws into a thai bank account I will have less of a problem with CGT

    can this be done without breaking thailand rules

Where is your legal residence? If Ireland, you are still liable to pay Irish tax so no change there. Thailand (under AIE) will declare your account balance to your legal residence i.e. Ireland.

How it runs is that if the income goes into ireland before I receive it then i have to pay tax but if it goes to thailand then Ireland do not grab the money 

A question answer between me and my irish accountant is pasted below

 

 First point whilst doing the 2022 return you suggested that I should have left the funds from selling my shares in my degiro account rather than transferring said money into my BOI account....please explain why it is better to leave money in my degiro account       Although you are not resident in Ireland you are ordinarily resident for 3 years for 3 years after you leave and you are taxable on foreign income remitted to Ireland.
