How Asa Marsh Has Helped High Net Worth Investors Understand Thailand’s Real Tax Position, And Why Most People Get It Wrong
The claim that went viral was simple: move to Phuket, buy property, pay 0% tax on your worldwide income. Samuel Leeds, a client of mine, said something close to that in the video that set off weeks of noise. I covered the property side of that story in the first article in this series. This one is about the tax claim, because that is where most of the misunderstanding lives, and most of the opportunity too.
The claim is not wrong. It is just incomplete. And incomplete, when it comes to tax structuring, is the same as wrong.
What Changed in 2024, And Why It Matters
To understand why the Wealthy Global Citizen tax exemption is significant, you need to understand what happened to everyone else.
In September 2023, Thailand’s Revenue Department issued Departmental Instruction Paw 161/2566, effective from January 2024. Before that instruction, the standard interpretation of Section 41 of the Revenue Code had long been that foreign-sourced income was only taxable in Thailand if it was earned and remitted in the same tax year. Bring last year’s income in this year, and it fell outside the net.
That changed. From January 2024, any Thai tax resident, defined as anyone spending 180 days or more in Thailand in a calendar year, who remits foreign-sourced income into Thailand can be liable for Thai personal income tax on that income, regardless of when it was earned. Employment income, business income, property income from abroad, all of it potentially taxable on remittance, under the standard progressive rates, which reach 35% at higher income levels.
For the thousands of high net worth individuals who had been using the old interpretation as informal tax planning, this was significant. For LTR Wealthy Global Citizen holders, nothing changed. That distinction is worth understanding clearly.
What Royal Decree 743 Actually Says
Royal Decree No. 743, gazetted in May 2022, is the instrument that created the tax framework for LTR visa holders. Section 5 of the decree is the relevant provision for Wealthy Global Citizens.
Under Section 5, a Wealthy Global Citizen LTR holder is exempt from Thai personal income tax on income derived from employment, business or property situated abroad, when that income is remitted into Thailand. The exemption operates as a statutory carve-out from Section 41 of the Revenue Code, the same section that now catches standard Thai tax residents. LTR holders are explicitly outside its reach.
The practical effect: a qualifying WGC holder can spend more than 180 days a year in Thailand, becoming a Thai tax resident under the standard rules, and still remit foreign-sourced income into Thailand without Thai personal income tax exposure on that remittance. That is the substance behind the viral claim. Stated that way, it is accurate. The Revenue Department’s position on this is published at rd.go.th.
What the Exemption Does Not Cover
This is where most of the confusion enters, and where I spend the most time with clients.
The exemption covers foreign-sourced income. It does not cover Thai-sourced income. Salary earned under a Thai work permit, rental income from a Thai property, business income generated inside Thailand, none of that is touched by the Royal Decree 743 exemption. Those income streams are taxed at standard progressive rates.
The exemption also does not apply retroactively. Income earned before the LTR visa was granted does not fall within the exemption framework simply because it is remitted to Thailand after the visa is issued. If you bring pre-LTR income into Thailand after you hold the visa, you need to account for when that income was earned. This catches people who assume the visa date is the relevant reference point. It is not. The income origination date is.
And the exemption is not permanent by default. Sections 6 and 7 of Royal Decree 743 attach continuing compliance conditions. The holder must maintain their BOI qualifications and comply with the procedures prescribed by the Revenue Department’s Director-General. If those conditions are not met in a given tax year, the exemption can be suspended for that year and does not carry forward automatically. This is why I recommend clients file a return even in years where no tax is due, the filing documents the exemption claim and demonstrates ongoing compliance.
What I See in Practice
Most of the clients arriving from Dubai come to me with income that is genuinely well-suited to this structure. Passive income from investments held outside Thailand, business distributions from entities domiciled elsewhere, rental income from overseas property, these are the income types that the WGC exemption was designed for and that the Royal Decree 743 framework addresses cleanly.
What requires more work is the client whose income is mixed. Some foreign-sourced, some Thai-sourced, some pre-LTR, some ongoing. The exemption applies only to the foreign-sourced portion earned during the LTR validity period. Getting the accounting right, tracking what qualifies and what does not, is not complicated for someone with proper advice, but it is not automatic either.
The clients I have guided through this correctly all arrived having done one thing first: a proper income classification exercise with a qualified Thai tax adviser. That input, what income is, where it originates, how it will be remitted, shapes everything that follows. The visa application, the investment structure, the compliance approach. In the right order, this is a straightforward process. Out of order, it creates problems that are expensive to untangle.
Why This Is More Valuable Now Than When the Visa Launched
When the LTR programme launched in 2022, the foreign income exemption was useful. Since the 2024 Revenue Department instruction, it has become one of the only statutory safe harbours available to high net worth individuals who want to be based in Thailand without full exposure to Thai personal income tax on their global income.
The people I speak with who are serious about Thailand are not asking whether the tax position works. They are asking whether they qualify for the structure that makes it work. Those are different questions, and the second one is the one that matters.
Most of the people I work with are relocating from Dubai. They love it there, and so do I. But the region has shifted, and smart people plan ahead. My family has run a boutique advisory office in Phuket for a decade. I have been coming here since I was 12. When someone arrives from the Gulf asking whether Thailand’s tax position is serious, I am not reading from a brochure.
If You Want to Understand Your Own Position
The tax structure is real. The conditions are real. Whether it applies to your income, your structure and your timeline is a question that requires proper analysis, not a YouTube video, not a property show, not this article.
