Thailand has long collected relocators: a mild climate, affordable living, direct flights and a reputation as a place where foreign capital is left alone. Since 2024 the last part is no longer true. The country used to run a soft remittance principle — foreign income was taxed only if brought into Thailand, and only in the year it was earned. From 1 January 2024 the Revenue Department rewrote the rule: any remitted income of a tax resident is now taxable regardless of the year it was earned. Below — what exactly changed, what relief is in the works, and how the LTR and DTV visas change the calculus.
The Concept: the 2024 Change of Principle
Until 2024 the remittance principle worked in its soft version: foreign income was taxed only if the resident brought it into Thailand in the same calendar year it was earned. Waiting a year was enough — and the money entered the country tax-free. Instruction Por 161/2566 (in force from 1 January 2024) removed that deferral: remitted foreign income is now taxable regardless of the year it was earned. The remittance principle itself survives — Thailand still does not claim income you keep abroad, which puts it close to remittance regimes like the Cypriot non-dom or territorial systems like Georgia's. What changed is the moment of taxation: the "seasoning year" no longer saves you.
How It Works Now
- tax resident = 180+ days in a calendar year;
- what is taxed is remitted foreign income; income left abroad is not taxed (a remittance principle, not worldwide taxation);
- progressive personal income tax — from 5% to 35% (the top band applies above THB 5m a year);
- the idea of full worldwide taxation was discussed, but by 2026 it had effectively been abandoned in favour of softening the remittance rules — see below.
The Two-Year Relief Draft (2025–2026)
What matters for planning is the mechanics of the draft:
- substance: foreign income earned from 2024 onward and remitted in the year earned or the following calendar year would be exempt; remittances after the two-year window taxed at the ordinary 5–35% progression;
- goal: restore the incentive to bring capital into the country, which Por 161 removed;
- status: shelved by the December 2025 dissolution and the February 2026 election; until a final text is published, remittance planning follows the current rules.
Who Is Affected and How to Count
The rule catches any Thai tax resident — anyone spending 180 days or more in the country in a calendar year. That means relocators living on foreign dividends, interest and rent; pensioners with foreign payments; remote workers paid into foreign accounts. Citizenship and visa type are secondary — actual presence decides. Those who stay under the 180-day threshold and keep a traveller's calendar remain outside the Thai tax base.
An example. A resident earns dividends in 2025. Under the rules as they stand, tax arises in the year the money is brought in, whatever year it was earned: remit in 2026 and it is taxed at the progression; remit in 2027 and it is taxed too. The two-year window was never enacted, so it cannot be built into the calculation. Income accumulated before 2024 is protected by Por 162 and untaxed even if brought in later, so "old" capital is best kept on a separate account and not mixed with new money: otherwise proving its origin to the bank and the Revenue Department becomes harder.
The Visas: LTR and DTV
The LTR (Long-Term Resident) is the ten-year visa with a tax bonus. Four categories: Wealthy Global Citizen, Wealthy Pensioner, Work-from-Thailand Professional and Highly-Skilled Professional. Under Royal Decree No. 743 the first three are exempt from income tax on foreign income regardless of remittance; the highly skilled get a flat 17% on Thai employment income. The visa runs 10 years with a check at year five and no 90-day reporting. In January 2025 the Cabinet relaxed the criteria: the $80,000 annual income requirement was dropped and the definition of dependants widened; the Wealthy Global Citizen keeps the $1m asset threshold, $500,000 of it in Thai assets. For the Work-from-Thailand Professional the employer bar fell to group revenue of $50m (was $150m), and the five-year experience requirement was removed. In essence it is an investment residence permit.
The DTV (Destination Thailand Visa, launched July 2024) is a five-year multi-entry visa. It suits remote workers and freelancers serving foreign companies (workcation), participants in Thai "soft power" programs (Muay Thai, cuisine, medical) and family members. You show from THB 500,000 (≈$14,000) in the bank, typically seasoned three months; the visa gives up to 180 days per entry with one 180-day extension — about 360 days in a row. The fee is THB 10,000, the extension THB 1,900; since January 2025 filing is e-Visa only. The DTV carries no tax perks: at 180+ days you become a resident and pay under the general remittance rules.
Pairing the Visa with the Tax
- LTR (the first three categories) = immigration + exemption of foreign income. The cleanest option for the wealthy, pensioners and remote workers;
- DTV = convenient entry, but tax under the general rules.
Risks
- remittance planning: what to bring in and when; pre-2024 income (Por 162) and the two-year window draft;
- spending on a foreign bank card inside Thailand is treated in practice as a remittance (at the Bank of Thailand rate on the transaction date) — factor it into the math;
- CFC rules, the exit tax of the country you are leaving, the residency tie-breaker; CRS automatic exchange; bank compliance when bringing funds in;
- the two-year relief is still a draft — building it into plans as a guarantee is premature.
What to Do Now
The practical minimum until the relief passes: separate the flows. Keep pre-2024 income apart — it is protected by Por 162 and enters the country tax-free. Plan new foreign income under Por 161/162 as they stand: the two-year window is not law and must not be assumed. If the sums are serious, an LTR from the "wealthy" categories removes the remittance question entirely and is usually calmer than an annual remittance count. For those leaving Russia, the separate thread is a correct exit from Russian tax residency — to avoid being a resident of two countries at once.
Q/A
Is foreign income that is not remitted to Thailand taxed?
Not yet. The remittance principle survived the 2024 change: Thailand taxes only foreign income actually brought into the country, and money left abroad stays out of the base. Full worldwide taxation was discussed and by 2026 effectively abandoned in favour of softening the remittance rules. One trap: spending on a foreign bank card inside Thailand is treated in practice as a remittance, at the Bank of Thailand rate on the transaction date.
Who does the rule affect?
Any Thai tax resident — anyone spending 180 days or more in the country in a calendar year. Citizenship and visa type are secondary; actual presence decides. That catches relocators living on foreign dividends, interest and rent, pensioners with foreign payments and remote workers paid into foreign accounts. Stay under the 180-day threshold and you remain outside the Thai tax base.
Does the DTV give tax benefits?
No. The DTV is an entry status only: five years multi-entry, up to 180 days per entry with one 180-day extension, on a showing of about THB 500,000 in the bank. At 180 days or more in a calendar year you become a tax resident and pay under the general remittance rules. The foreign-income exemption belongs to three of the four LTR categories under Royal Decree No. 743.
What about income earned before 2024?
It stays under the old rule. Por 162 grandfathers income earned before 2024, so it is untaxed even when remitted years later. The consequence is bookkeeping: keep pre-2024 capital on a separate account and do not mix it with new money, or proving its origin to the bank and the Revenue Department becomes much harder.
Can I plan around the two-year relief?
No. The Revenue Department drafted it in mid-2025 — foreign income remitted in the year it is earned or the following year would be exempt, with later remittances taxed at the ordinary 5–35% progression — and the royal decree was prepared. Then parliament was dissolved on 12 December 2025, elections followed on 8 February 2026, and the reform is stuck pending a new cabinet. Nothing has appeared in the Royal Gazette, so plan under Por 161/162 as they stand.
