Basically as there's a lot of confusion, i will lay out a scenario.
You have bob the builder, bob the builder owns a overseas company, few assets, and earns income in
crypto/stocks overseas.
Bob the builder net-worth in liquid terms is 1m in the bank $ in Jan 2024, in asset terms its (real-estate, stocks, bonds, crypto, companies) an additional 9m $ pre-2024 it was roughly 5.4m$ in liquid and
investment assets, it's risen to 10m$ in total now.
Bob the builder utilises the residual income from his real-estate to finance his costs within
Thailand, he remits this, he declares it and he pays tax on it as remitted income - he doesn’t need to due to the principle rule - but he’s confused.
Bob the Builder then sells one of his homes overseas for 3 x the amount and pockets his funds into his bank account overseas, there's 0 income in Thailand, as he hasn't remitted that income, and intends to speculate on SUI in the crypto markets, as it will likely 10x from here.
Bob the builder has also made a profit on his stonks of roughly 60% he liquidates those to that bank account, there is 0% tax within Thailand on those stonks, he has also made 1000% on some shitcoins like IAGON and deposits that via a
Crypto exchange into his bank account, all in all he's made about 1m$ so far this year.
Bob didn't take a salary intending to take a
dividends later (recommended approach), but if he took a salary for his overseas income (residual salary) in to his overseas account that's tax free if he wanted to, from his companies.
He didn't remit that, he deposited into his account overseas and it's tax free in Thailand.
Later on he wants to remit his 1m tax free, so he sits there and calculates his 'principles' before 2024, and has a principle pre-2024 investment of 5.4m $ (pre-2024), so he can remit 5.4m$ tax free into Thailand without having to glide around for 7 months in a year to harvest additional principle allowance.
It's really that simple.
^ basically sums up my approach as i had a sit down with the revenue department and legal to determine the intricacies and their impact, having a known net-worth of XX-XXXm$ (paper) + recorded in court, so in my case i was informed I could harvest against that as that was pre-2024.
Anything i earn now overseas is tax exempt if structured (dividends) or income from markets/assets and non-remitted, but would also be offset by 'principle-rule' if remitted.
Tell him to get his records straight and signed off and he will be fine.
FYI if someone is making money (serious) i am always interested to see if it can be replicated, rather than get annoyed by, its a brilliant way to have something to do (new) and also get rewarded for finding a crack in the system.
