A Destination Thailand Visa gives you five years of entries and up to 180 days of stay per visit, but it does not lower your tax bill. Spend 180 days or more in Thailand within a calendar year and you become a Thai tax resident for that year; once you remit foreign-sourced income into the country while resident, it is taxable, even if it was earned years earlier, as long as it was earned on or after 1 January 2024 in a year you were a Thai tax resident. Income earned in a year you were not a Thai tax resident stays outside this rule, however many days you later spend in Thailand. Deciding how many days to spend in Thailand also means weighing flights and extension fees against the tax — the worked example below puts both sides on the same page.
In short
- A DTV gives no tax exemption: the 180-day residency test and the remittance rule apply exactly as they would without the visa.
- Residency is counted over the calendar year, not per visa entry — every day you spend in Thailand that year is added together.
- Foreign income you remit into Thailand is taxable only if it was earned on or after 1 January 2024, in a year you were a tax resident.
- A draft rule that would exempt income remitted in the same year it was earned, or the year after, has not become law.
- Choosing how many days to spend in Thailand is a legitimate planning decision, not a way to avoid tax you owe at home.
The example: income, transfers, days in Thailand
The numbers below are a condition example, not a client file or an official calculation. Picture a freelance developer with foreign clients who earns ฿2,400,000 a year and plans to bring ฿1,200,000 of it into Thailand to cover rent, living costs and a local bank balance. We leave savings and pre-2024 earnings out of the example, because under Revenue Department instruction Por. 162/2566 that money stays outside the remittance tax regardless of residency.
Our freelancer already holds a DTV and meets its usual conditions: proof of at least ฿500,000 in funds, a foreign employer or foreign clients, and no work for a Thai company. If you still need to apply, our DTV visa requirements and documents guide covers the current filing rules in detail. What matters here is not the visa application, but a separate question: how the same income is taxed depending on how many days they spend in the country.
Scenario 1: under 180 days a year
If our freelancer keeps total days in Thailand under 180 in the calendar year, the 180-day test is not met, so Thai law does not treat them as a tax resident that year. Assuming the ฿1,200,000 was earned in that same calendar year, for work done abroad for foreign clients — so it is foreign-sourced, not Thai-sourced — none of it is taxable in Thailand on that basis: the exemption rests on not being a Thai tax resident in the year the income arose, not merely on where the money is banked or when it is transferred (Por. 162/2566, as summarised in the Revenue Department's Q&A on Por. 161/2566 and Por. 162/2566). Income from work actually done in Thailand is a different question and can be taxed whether or not the 180-day test is met. Our guide to tax residency: the 180-day rule explains the test in full.
Planning around that threshold means tracking every day physically present, not every visa period. A single DTV entry can already cover up to 180 days, so one long stay plus one extension could put a traveller close to residency without any extra trips. Several shorter visits within the same year still add up toward the same 180-day total, because the test looks at the whole calendar year, not any single entry. How the day of arrival and the day of departure are counted is not spelled out in the guidance we have seen, so if your count is close to the line, keep your own log of entry and exit stamps and count conservatively.
Scenario 2: over 180 days with remittances
Once total days in Thailand reach 180 or more, our freelancer is a Thai tax resident for that year. Assuming the ฿1,200,000 is foreign-sourced income that arose on or after 1 January 2024, in a year our freelancer was also a Thai tax resident, it becomes assessable once remitted. Here is a worked tax example for a remote worker in Thailand who crosses that line.
For this example, we treat the income as falling under the service-income category of the Revenue Code (section 40(2)), to which a flat 50% expense deduction applies, capped at ฿100,000; every resident also gets a personal allowance of ฿60,000. Which category applies to your own income, and whether the deduction works the same way for foreign-sourced earnings, needs checking case by case:
1,200,000 − 100,000 − 60,000 = 1,040,000 ฿ net taxable income
| Net income band (฿) | Rate | Tax on this band |
|---|---|---|
| 0 – 150,000 | 0% | ฿0 |
| 150,000 – 300,000 | 5% | ฿7,500 |
| 300,000 – 500,000 | 10% | ฿20,000 |
| 500,000 – 750,000 | 15% | ฿37,500 |
| 750,000 – 1,000,000 | 20% | ฿50,000 |
| 1,000,000 – 1,040,000 | 25% | ฿10,000 |
| Total | ฿125,000 |
The tax on ฿1,200,000 remitted comes to ฿125,000 under the Revenue Department's personal income tax rate table and allowances — a condition example, not a Revenue Department ruling on this specific case. Our freelancer would also need a Thai tax ID and would file an annual PND 90 return; foreigners earning assessable income in Thailand are expected to register for a Thai tax ID within 60 days of first deriving that income, per the Revenue Department's Tax Identification page; the exact starting point for income earned abroad is best confirmed directly with the Revenue Department. Keeping bank statements and invoices that show when the underlying income was actually earned is what separates taxable 2024-onward income from money that stays exempt because it was earned earlier or during a year of non-residency.
What a double tax treaty changes
Where a double tax treaty between Thailand and your home country gives Thailand the right to tax a type of income, Thailand's progressive scale applies, and your home country may give you a credit for the Thai tax paid. Thailand itself only credits foreign tax under a treaty — there is no credit for tax paid to a country Thailand has no treaty with. We do not cover the wording of any single treaty here, because the result depends on the specific article and the type of income involved. Our team reviews the treaty between your country and Thailand case by case before you remit anything.
Visa and travel costs
This is where the true cost of living on a DTV becomes clear. Picture our freelancer planning two shorter stays in the year that together total, say, 150 days, with flights out booked before day 180 is reached — here the cost is flights rather than tax. Staying in Thailand continuously past 180 days on one DTV entry means paying the visa's own in-country extension fee instead; a single continuous stay is capped at 360 days, after which the visa requires leaving and re-entering regardless of tax planning.
| Scenario 1: under 180 days | Scenario 2: over 180 days | |
|---|---|---|
| DTV application fee | ฿10,000 equivalent, charged by the mission in local currency, paid once for the 5-year visa | ฿10,000 equivalent, charged by the mission in local currency, paid once for the 5-year visa |
| In-country extension | not needed | ฿1,900 for a 180-day extension |
| Trips out of Thailand | cost of return flights — a condition example, not a fixed figure | none within the first 360 continuous days; after that the DTV requires leaving and re-entering |
| Thai tax on ฿1,200,000 remitted | ฿0, on the foreign-sourced, non-resident-year assumptions above | ฿125,000 (condition example, same foreign-sourced-income assumptions) |
The application fee is identical in both columns, because it is paid once for the whole five-year visa regardless of how you use it. What differs is an extension fee against the cost of a trip, and tax against staying put. In this example, ฿125,000 of tax is far larger than one extension fee or a condition example travel budget of, say, ฿60,000 for a few return flights. On this specific calendar and these specific assumptions about the income, staying under 180 days comes out cheaper — provided the extra cost of travel, of living outside Thailand during those weeks, and of any tax owed elsewhere stays below the ฿125,000 Thai tax this scenario would otherwise trigger. The balance shifts with a smaller remitted amount, a longer stay you actually need for work or family reasons, or a treaty credit that offsets part of the Thai tax — which is why we work through the real numbers rather than a rule of thumb. See our typical scenario of a DTV refused over a bank statement for how proof-of-funds documents, not just day-counting, can also decide whether a DTV plan works at all.
What is not settled yet
Two proposals would change this picture, and neither is law. A Revenue Department draft would exempt foreign income remitted in the same calendar year it was earned, or the year after; it has not become law, and no official enacted text has been identified. A separate draft would tax Thailand's tax residents on worldwide income whether or not it is remitted; its status after the 2026 general election is not confirmed. Until either becomes law, plan around the rules in force today: Por. 161/2566 and Por. 162/2566, as described above.
An alternative: LTR Work-from-Thailand
If staying in Thailand for most of the year is the point, not a trade-off to minimise, the Long-Term Resident (LTR) visa's Work-from-Thailand Professional category is worth comparing with the DTV. The Thailand Board of Investment, which runs the LTR programme, states that this category exempts foreign-sourced income from Thai tax. Its eligibility rules are separate from the DTV's and generally stricter, and our team can tell you whether your income and employer fit them before you apply.
How to run your own numbers
- Count every day you expect to spend in Thailand in the calendar year, not per visa entry.
- List what you plan to bring into Thailand and where it comes from — salary, freelance invoices, investment income, savings.
- Work out when each amount was actually earned: before 2024, from 2024 onward, and in a year you were or were not a Thai tax resident.
- Identify the type of income for Thai tax purposes — employment, freelance services, rent, dividends — because the deductions differ.
- Check what the double tax treaty between Thailand and your country says about that type of income.
- Work out what the same income would cost you in tax at home, so you compare the whole picture, not just the Thai side.

What to do next
Working through a year like this before it starts is cheaper than fixing it afterwards. Our team handles DTV applications and extensions, and reviews the tax side of a stay before you commit to it. Send us how many days you are planning in Thailand and what you expect to remit, and we will answer within 24 hours; the cost is confirmed with you before we start.
