Completely wrong, you also pay tax on money you bring into Thailand, no matter where you earned the money.
At the moment only money brought in that you earned before 2024 is not taxable. The new proposed law will also make money brought in in the year you earned it or the year after that tax free.
If your home country has a DTA and you pay tax in your home country, it depends on the DTA if you have to pay tax or not.
In most cases when there is a DTA effectively you pay the highest of tax in your home country and Thailand.
And when your home country has no DTA with Thailand you just might end paying double tax, in both countries.
