Thailand changed its tax rules in 2024. Most expats have not adjusted their financial structure.
Foreign income remitted to Thailand is now taxable for tax residents. The LTR visa creates a separate regime entirely. UK pensions, European pension portability, Irish UCITS structuring, and Thai property succession rules all intersect in ways that generic advice cannot address. This page covers what the rules actually are and where the structural decisions lie.
What changed on 1 January 2024, and why it matters for every expat in Thailand
Thailand's tax treatment of foreign income shifted materially in 2024. Under Revenue Department Instruction No. Por 161/2566, effective from 1 January 2024, Thai tax residents are now taxable on foreign-sourced income in the year it is remitted to Thailand, regardless of when it was earned. The critical word is "remitted." Income sitting offshore, in a foreign bank account, never transferred to Thailand, remains outside Thai tax scope entirely.
Prior to 2024, a widely-used interpretation held that foreign income earned in a year prior to remittance was exempt from Thai tax. That position is no longer available for income earned from 2024 onwards. If you are a Thai tax resident (spending 180 days or more in Thailand in a calendar year) and you remit foreign income to Thailand, that income is subject to Thai personal income tax in the year of remittance.
Decisions about when and how to transfer money from foreign accounts into Thai accounts now carry direct tax consequences. An expat in Bangkok moving money from a UK current account to a Thai baht account is triggering a taxable event, not making an administrative transfer. The source of the funds, the nature of the income (salary, pension drawdown, rental income, capital gains), and whether a double taxation agreement applies all affect what is ultimately owed.
Thailand's progressive income tax rates apply to chargeable income after deductions and exemptions:
| Chargeable Income (THB) | Rate |
|---|---|
| 0 to 150,000 | Exempt |
| 150,001 to 300,000 | 5% |
| 300,001 to 500,000 | 10% |
| 500,001 to 750,000 | 15% |
| 750,001 to 1,000,000 | 20% |
| 1,000,001 to 2,000,000 | 25% |
| 2,000,001 to 5,000,000 | 30% |
| Above 5,000,000 | 35% |
DTA protection, credit relief, and the mechanics of what counts as a remittance
Thailand has double taxation agreements with over 60 countries, including the UK, France, Germany, the Netherlands, Belgium, Sweden, and most EU member states. These treaties determine which country has primary taxing rights on specific income categories, and whether credit relief is available to prevent the same income being taxed twice.
Under the Thailand-UK DTA, private pension income (SIPP drawdown, personal pensions, occupational scheme pensions) paid to a Thai tax resident is generally taxable only in Thailand. UK government and public service pensions (civil servants, NHS, teachers, armed forces) remain taxable only in the UK. The practical consequence is that a British expat drawing from a SIPP in Thailand may owe Thai income tax on those withdrawals at progressive rates, with no UK deduction available because UK withholding was not applied. The timing, size, and year of remittance of each withdrawal all determine the Thai liability.
Under the Thailand-France DTA, employment income and pension income have similar treatment. The interaction is more complex for French nationals who may retain French tax residency under French law even while physically based in Thailand. French fiscal residency tests include domicile, principal place of business, and centre of economic interests. It is not purely a day-count rule. French nationals in Thailand should verify their French residency status independently before assuming Thailand has exclusive taxing rights.
What constitutes a "remittance" for Thai tax purposes is broader than a bank transfer. Foreign income used to pay Thai expenses, including credit card charges billed to Thai accounts, loan repayments to Thai banks, and property purchases in Thailand funded from foreign accounts, may constitute a remittance. The Thai Revenue Department has not issued exhaustive guidance, but the principle is that any use of foreign-sourced income within Thailand falls within scope. Leaving foreign income invested offshore, in foreign-domiciled funds or accounts, and not repatriating it, remains the cleanest way to defer or avoid Thai tax on that income.
QROPS, SIPP drawdown, CETV timing, and what changes when your tax address is Bangkok
SIPP and drawdown in Thailand
A SIPP held in the UK remains a UK-regulated scheme regardless of where the member is tax-resident. There is no HMRC requirement to transfer it simply because you have moved to Thailand. Drawdown from a SIPP while tax-resident in Thailand will typically not attract UK income tax, as HMRC allows non-resident claims under a NT (nil tax) coding, but the income may be taxable in Thailand under the DTA if it is classified as private pension income. At Thai progressive rates of up to 35%, the tax exposure on significant drawdown can be material.
The pension commencement lump sum (PCLS), the 25% tax-free cash entitlement available from most UK defined contribution schemes, is exempt from UK income tax by statute. Whether it is taxable in Thailand on remittance depends on DTA interpretation and the nature of the PCLS. As a lump sum rather than periodic income, it may fall into a different DTA category. Case-specific analysis is needed before large PCLS withdrawals are transferred to Thailand.
QROPS from Thailand
A Qualifying Recognised Overseas Pension Scheme (QROPS) transfer takes the pension out of the UK regulatory regime entirely. For Thailand-resident expats, a QROPS in a third jurisdiction (Malta, Gibraltar, Isle of Man) may remove the pension from both UK and Thai ongoing tax scope, but HMRC's overseas transfer charge applies to QROPS transfers where the member is not resident in the same country as the QROPS. As of 2023, the overseas transfer charge is 25% of the transferred value in most cases. The economics of a QROPS transfer for a Thailand-resident therefore require a long horizon and a specific structure to justify the upfront charge. It is not a default recommendation.
CETV and DB scheme timing
For UK defined benefit (DB) scheme members considering a CETV transfer while in Thailand, the timing of the transfer relative to Thai tax residency, and the structure of the receiving vehicle, determine the Thai tax outcome. A CETV transferred directly to a SIPP and then drawn in Thailand is treated differently to a CETV transferred to a QROPS in a jurisdiction with no Thai DTA. DB transfer decisions should never be made on CETV alone. They require a full financial picture including health, income sources, dependents, and the specific Thai tax position.
French AGIRC-ARRCO, German Riester, Dutch AOW: what the gaps look like from Bangkok
European expats in Thailand carry home-country pension entitlements that are consistently underexamined. The pension does not disappear when the person moves. It accrues, often sub-optimally, and the interaction with Thai tax residency adds a layer of complexity that no single country's pension authority addresses.
French nationals who contributed to the AGIRC-ARRCO supplementary pension system accumulate points throughout their French employment. Those points retain their value regardless of where the individual subsequently lives. When French pension income begins paying (typically from age 62 to 67 depending on birth year and contribution history), it is paid from France to wherever the pensioner lives, including Thailand. The Thailand-France DTA generally gives Thailand taxing rights on private pension income from French sources for Thai residents, but France applies a 25% withholding tax by default on pension payments to non-residents. Claiming the correct DTA rate requires filing a form 5000 residency certificate with the French pension administrator and France's Direction des Impots des Non-Résidents. Most French expats in Thailand have not done this, and are paying the default withholding unnecessarily.
German nationals with Riester or Rürup (Basisrente) contributions face a different problem. Riester subsidies (the state top-up payments and tax deductions) are reclaimed by Germany when the beneficiary moves outside the EU/EEA permanently. Thailand residency triggers this reclaim. A German expat who has contributed for 10 years to a Riester contract and then emigrates to Thailand loses the accumulated subsidy, not the personal contributions. The Rürup pension, by contrast, carries no EU-residency condition. Contributions remain tax-deductible in Germany during the contribution phase, and the pension is taxed in Germany or in Thailand under DTA provisions when it is eventually drawn. For German nationals planning long-term Thailand residency, the Riester-versus-Rürup question should be resolved before emigration, not after.
Dutch nationals are entitled to the AOW (Algemene Ouderdomswet) state pension, which begins paying from age 67. AOW payments are reduced by 2% for every year the individual was not resident in the Netherlands between ages 15 and 67. An expat who spent 15 years in Thailand will receive a permanently reduced AOW on return. Voluntary contributions to the SVB (Sociale Verzekeringsbank) can partially fill AOW gaps, but the window for voluntary contributions is time-limited and must be initiated proactively. Dutch expats in Thailand should calculate their expected AOW gap and model whether SVB voluntary contributions are cost-effective before the window closes.

The Long-Term Resident visa and its financial planning implications
Who qualifies and what it costs
The Wealthy Global Citizen category requires assets of at least USD 1 million, a personal income of at least USD 80,000 per year, and investment in Thailand of at least USD 500,000 in government bonds, Thai real estate, or foreign direct investment. The visa is 10 years (5+5), renewable. Annual fee is THB 50,000. The financial eligibility thresholds are high by design: the BOI specifically targets independently wealthy individuals, not employment-dependent expats.
The key financial planning implication: LTR Wealthy Global Citizens are exempt from Thai tax on foreign-sourced income entirely. This is a categorical exemption, not a remittance exemption. Income remitted from abroad is not subject to Thai personal income tax regardless of amount or source. This fundamentally changes the remittance calculation relative to a standard Thai tax resident.
The retirement-focused category
Wealthy Pensioners must be age 50 or above and have a pension or passive income of at least USD 80,000 per year, or passive income of USD 40,000 per year combined with Thai property investment or government bond holdings of USD 250,000. The annual fee is THB 50,000. The visa grants a 10-year right of residence.
LTR Wealthy Pensioners also benefit from the foreign income exemption. A British retiree drawing SIPP income above the threshold, or a French retiree drawing AGIRC-ARRCO above the threshold, who qualifies for the Wealthy Pensioner LTR, does not pay Thai income tax on those remittances. This makes the LTR visa a structural tax decision, not merely an immigration convenience, for high-income European retirees in Thailand.
Employment income and the 17% flat rate
The Work-From-Thailand Professional category targets high-skilled employees of overseas companies with income above USD 80,000 per year and at least five years of professional experience. Thai-sourced employment income for LTR Work-From-Thailand holders is taxable at a concessionary flat rate of 17%, compared to the standard progressive rate of up to 35%. Foreign-sourced employment income remitted to Thailand is also exempt.
The 17% rate applies only to income from Thai-sourced work: employment with a Thai entity or work performed in Thailand for a Thai employer. For employees of overseas companies working remotely from Thailand, the structure of the employment contract determines whether income is Thai-sourced. If the employer is entirely offshore, the income is foreign-sourced and exempt under the LTR regime. Contract structure and payroll routing are material planning decisions before taking up this visa.
Irish UCITS, currency positioning, and what Thai regulations allow foreign investors to hold
The most consequential structural decision for a Thailand-based expat investor is not which index to track. It is which legal wrapper holds the funds, and in which jurisdiction those funds are domiciled. A US-domiciled ETF (SPY, VTI, QQQ) exposes any non-US person to a 40% US estate tax on holdings above USD 60,000 at death. This is not a minor technical detail. It is the default position under US law for any non-US domiciliary holding US-sited assets. For an expat with USD 300,000 in a US-domiciled index fund, the estate tax exposure is up to USD 96,000. Their family would be left to navigate an IRS filing from Thailand.
Irish-domiciled accumulating UCITS funds (iShares IWDA, Vanguard VWRP, Xtrackers XDWD) track the same underlying global indices. The performance difference is negligible. The structural difference is material: Irish UCITS are not US-sited assets and do not carry the US estate tax. They also benefit from Ireland's double tax treaty with the US, which reduces US dividend withholding to 15% rather than the 30% rate paid by direct non-US holders. The accumulating share class reinvests dividends internally, meaning no taxable income event is triggered in Thailand until the position is sold and proceeds are remitted.
Thailand does not restrict foreign nationals from holding foreign investment accounts. A British expat in Bangkok can hold a brokerage account in the UK, Ireland, or Singapore, invest in Irish-domiciled UCITS, and remit only what is needed for Thai living expenses, managing the Thai taxable base directly. What Thailand does restrict is the ability of foreigners to borrow against foreign-held assets through Thai banks, and the ability to hold certain Thai-listed securities through some nominee structures. For an expat accumulating wealth outside Thailand for eventual use in a third country (retirement in France, Portugal, or back in the UK), this restriction is irrelevant.
Currency positioning for a Thailand-based expat typically involves THB spending exposure, GBP or EUR pension entitlements, and USD or SGD income. Each of these is a live currency risk. The THB is managed by the Bank of Thailand and has historically been correlated to regional export cycles. An expat planning to retire in Europe but accumulating in THB-denominated savings is taking a currency bet, whether or not they have framed it that way. The structural answer is to accumulate in the currency of intended retirement, or in a USD or EUR-denominated vehicle, while keeping only a cash buffer in THB.
Thai property, succession law, foreign wills, and what foreigners can and cannot own
Foreigners cannot own Thai land outright
This is not a grey area. Under Thai law, foreign nationals are prohibited from owning freehold land in Thailand. What foreigners can own is a condominium unit, subject to the condition that no more than 49% of the total floor area of a condominium building is owned by non-Thai nationals. The foreign quota limit is per building, not per development, and buildings in popular expat locations frequently have their quota fully subscribed.
The common workarounds (a Thai Limited Company holding land, a long-term lease with Chanote title over 30-year options, or a nominee arrangement) each carry significant legal risk. Thai authorities have periodically prosecuted nominee land ownership structures. A lease provides usufruct rights but not ownership and does not transfer to heirs in the same way as freehold. Expats who have made significant financial commitments to Thai property through a company or nominee structure should obtain independent Thai legal advice on the structural exposure.
From a wealth management perspective, Thai property held through informal structures should not be treated as a reliable portfolio asset. It is illiquid, structurally complex, and non-transferable to heirs in the same manner as Irish UCITS funds or a UK pension. The financial planning position for most European expats in Thailand is to hold investable assets offshore and treat Thai property as a lifestyle asset with uncertain exit value.
Thai intestacy rules and how they interact with European estates
Thailand operates a statutory heirship system under the Civil and Commercial Code. In the absence of a valid will, assets located in Thailand are distributed to statutory heirs in a fixed order: descendants, parents, siblings (full and half blood), grandparents, uncles and aunts, in six classes with each class excluding the next. A surviving spouse takes concurrently with the first class (children), with a share that depends on the number of children.
Thailand does not have a European-style forced heirship reserve in the way that France imposes a réserve héréditaire or Spain enforces a legítima. A Thai will can generally disinherit adult children, though the rules around legal heirs for minor children are more complex. For European expats whose home country law does impose forced heirship (particularly French nationals), the applicable law for estate purposes depends on where assets are located. French assets are governed by French succession law, even for an expat residing in Thailand.
A foreign will is recognised in Thailand if it meets the formal requirements of either Thai law or the law of the testator's nationality at the time of making the will. In practice, a Thai will and a home-country will addressing respective asset pools is the cleaner approach. Expats with assets in Thailand and their home country should not assume a single will in one jurisdiction covers both.
Thailand introduced an inheritance tax in 2016. It applies at 5% (to non-lineal heirs) or 10% (to unrelated beneficiaries) on inheritance above THB 100 million received from a single deceased person. The threshold is high enough that it does not affect the majority of expat estates in Thailand, but it exists and applies to Thai-located assets regardless of the beneficiary's residency.
The cleaner succession path for globally mobile expats
For European expats in Thailand with the majority of their wealth in offshore accounts (a SIPP, Irish UCITS holdings, a home-country property), the succession path is materially simpler than for those with significant Thai-located assets. Offshore pension funds pass via beneficiary nomination, not via a will, in most UK and European schemes. This means the pension does not form part of the probate estate and can pass to nominated beneficiaries quickly regardless of where the holder was resident at death.
Irish UCITS funds held in a brokerage account in the UK, Ireland, or Singapore pass via the account's probate process in the jurisdiction of the brokerage. This is a known, regulated process. Thai probate for Thai-located assets is a separate, slower process that may require a Thai-speaking lawyer, Thai court filings, and can take 12 to 24 months before assets can be transferred. Keeping investable assets offshore reduces estate administration complexity materially, quite apart from any tax considerations.
Bridging the gap between death and asset release
The time between death and the release of probate assets can run to 12 to 24 months for Thai-located assets. During that period, a surviving spouse may have limited access to joint-account funds, no access to Thai property proceeds, and restricted access to offshore assets while probate is being administered. Life assurance written in trust, or held in a structure that bypasses probate (such as a pension fund with an active beneficiary nomination), provides immediate liquidity to surviving dependants.
For European expats in their 40s and 50s in Thailand, the cost of term life cover written in trust in the UK or through a European insurer is typically low relative to the liquidity protection it provides. A joint life policy ensuring the surviving partner can cover Thai living expenses, school fees, and housing costs for 12 to 24 months without needing to liquidate illiquid assets is a basic element of a complete financial structure. Most expats do not have this in place.
