Thailand sits 81st out of 217 in our world ranking, with a FiScore of 5.6 out of 10. For decades it was one of the great open secrets of the expatriate world: bring your foreign income in a year after you earned it, and it arrived untaxed.
That ended on 1 January 2024. Most of what you will read about Thai tax was written before it did.
The rule that changed
Departmental Instruction Por. 161/2566, issued in September 2023, reversed a practice that had stood for decades.
Since 1 January 2024, any foreign income remitted into Thailand by a Thai tax resident is subject to personal income tax, regardless of the year in which it was earned. The old strategy of waiting until the following calendar year no longer works, because the year no longer matters.
Tax residence is triggered at 180 days in a Thai calendar year, not 183, and the days do not have to be consecutive. That threshold catches a great many people who assume the usual 183.
What is still exempt
Two exemptions survive, and they matter.
Savings accumulated before 1 January 2024 remain exempt when remitted. Money you already held before the rule changed keeps its old treatment, which is why the date of a bank statement has suddenly become an important document.
LTR visa holders are explicitly exempt from the remittance tax under Royal Decree 743. Three of the categories carry the exemption:
| LTR category | Broad requirement |
|---|---|
| Wealthy Global Citizen | substantial assets and investment |
| Wealthy Pensioner | pension income of at least 80,000 USD a year |
| Work-from-Thailand Professional | salary of at least 80,000 USD a year from a foreign employer |
For someone whose income clears those thresholds, the LTR visa turns Thailand back into what people remember it being. For everyone else, it does not.
The exemption everyone is waiting for is not law
Here is the point that a lot of confident writing gets wrong.
A draft amendment circulated in 2025 proposing to restore a partial exemption: income remitted in the year it was earned or the following year would remain taxable, older income would not. A two-year window rather than the old permanent deferral.
As of August 2026 this is still a draft. It is not the law. Articles that describe it as the current rule are describing something that has not happened, and planning a move around it is planning around a proposal.
The rest of the system
| Tax | Rate |
|---|---|
| Personal income | 0 to 35% |
| Corporate | 0 to 20% |
| VAT | 7% |
The personal scale is progressive and reaches 35%. Corporate tax tops out at 20% with reduced rates for smaller companies. VAT at 7% is among the lowest in Asia.
If you are American
Citizenship-based taxation applies as always, and Thailand adds a specific complication: if Thailand now taxes your remitted income, you may face tax in both places, mitigated but not always cancelled by foreign tax credits.
The trap runs the other way too. Structuring to avoid remitting income into Thailand does not reduce your US liability by a cent, because the United States taxes income when earned, not when moved. Two systems, two logics, and they do not line up.
The drawbacks
The rules changed once and can change again. A practice that stood for decades was reversed by an administrative instruction, not by parliament. That tells you how fast the ground can move.
Enforcement is still settling. How the rule is applied in practice, what documentation satisfies an auditor, how pre-2024 savings must be evidenced: all of this is being worked out, and early arrivals are the test cases.
Visa complexity is real. Thailand has many routes and most carry conditions that are easy to breach accidentally.
Banking has tightened considerably for foreign residents.
So, who is Thailand for?
- Someone who qualifies for an LTR visa: the exemption is explicit and the country is excellent. This is the clearest case.
- Someone living on pre-2024 savings: still workable, with careful documentation.
- A remote worker under the thresholds: much less attractive than the reputation suggests. Model the remittance tax properly.
- Someone spending under 180 days a year: not a tax resident, and the whole question falls away. That is worth planning around.
