not the way it works but yes consult a tax expert. The tax liability is based on remittance. Under the new rules, if you remit money into Thailand it will be taxed regardless of the source. Whatever tax you have paid in a dual tax agreement country, can be used to offset the Thai tax. Little or no home country tax, little or no offset. Hopefully, the powers that be will recognize the looming disaster.
could very well be true but no one should trust the durability of government pronouncements. You can do 90 reports online until you can't, you can do combination methods until you can't, you don't need a TM 30 after an international travel until you do.....
