Those who already hold a visa that allows for one-year extensions (by reasons of marriage, investment, or Elite visa) are able to manage their Thai-American Amity treaty companies without a work permit.
Those who do not require a work permit will still be required to pay personal income tax; if a corporation then you are paid a salary and you pay personal income tax on that. If you have a Sole Proprietorship, then you pay a percentage of your income if you use the standard fixed deduction. If you use expenses with receipts, then it’s the personal income tax on your net profit.
