Foreign-income and remittance planning
Thailand's foreign-income rules require a record of when income was earned, the person's residence position and when it is brought into Thailand. A transfer from an overseas bank is not enough information to classify it. Distinguish original capital, income and investment gains.
Specific LTR categories can have foreign-income tax benefits, but an ordinary long-stay or retirement visa does not grant the same relief. Check the applicable law and treaty before relying on a proposed exemption or treating an old description of same-year remittances as current guidance.
Country facts to keep in view
- Personal income tax
- 0–35%; foreign remittances can be taxableResidents can owe tax on foreign income earned from 2024 onwards when brought to Thailand, even in a later year. Specific exemptions and treaties matter.
- Company tax
- 20% standardQualifying smaller companies have 0%, 15% and 20% profit bands. Investment incentives and large-group minimum-tax rules differ.
- Dividend tax
- 10% Thai dividends; foreign income rules differResidents may elect final 10% treatment for Thai-company dividends. Foreign dividends can be subject to ordinary rates when remitted.
- Foreign pension tax
- 0–35% if taxable and remitted; LTR relief possibleForeign pension receipts need treaty and remittance review. Qualifying LTR categories have specific foreign-income exemptions; an ordinary retirement visa does not grant them.
A situation worth reviewing
A person with long-held savings, recent dividends and a pension should keep evidence identifying the source of each transfer. The tax position may depend on the income and dates, rather than on which bank account sends the payment.
LTR Wealthy Pensioner versus ordinary retirement
The LTR Wealthy Pensioner category has passive-income, age, financial and medical requirements. Its tax benefits should be reviewed only after establishing category eligibility and the nature of the receipt. Compare it with the permission and tax treatment available under an ordinary retirement route.
A Thai retirement mutual fund is a different subject: it is a local savings arrangement with contribution and withdrawal conditions, not the source of the LTR exemption. It is not automatically useful to someone already living on foreign pensions, and US persons need fund-classification review.
Income today, flexibility tomorrow
Two retirees with similar spending may have different outcomes if one qualifies for an LTR category and the other uses ordinary retirement permission. Compare the household's actual pension and passive-income evidence before assuming their foreign remittances receive the same treatment.
For UK assets and UK connections
The UK Thailand convention has no dedicated private-pensions article. Review the actual pension and source-country position rather than assuming a result from another treaty. Government-service payments have a separate provision.
Confirm departure reporting and keep the earning-year, residence and transfer records relevant to Thailand. Review a large payment before fixing its date, and confirm provider access for the new address.
For US persons
Review the US Thailand treaty for the actual income and applicable saving-clause position. US citizenship or resident-alien status can keep US obligations relevant even where a qualifying Thai category provides local relief.
A 401(k), IRA, Roth and taxable investment account should not receive one blanket answer. Review foreign-fund classification, including PFIC concerns, before adding a Thai savings product or international wrapper.
Before changing an arrangement
Compare the existing position with the proposed arrangement after fees, taxes and access restrictions. Keep a simple record of who owns each asset, where income arises and when it will be used. A lower headline rate is only useful if the account or regime qualifies and the structure remains appropriate when your plans change.
YOUR EXISTING ASSETS
How could your accounts fit?
Open the accounts you hold. These are starting points for a review, with the conditions and evidence attached to each finding.
UK accounts
UK ISA! High priority
ISA income needs a remittance trail
UK ISA relief does not automatically shelter foreign income brought into Thailand.
Distinguish capital, income and gains and retain an earnings-and-remittance trail. ISA relief remains a UK rule. Track the earning year, Thai tax residence in that year and the nature of the remittance. Ordinary retirement residence does not establish the specified LTR foreign-income exemption.
Worth exploring: Compare a documented withdrawal and remittance plan before adding another wrapper.
Ask a planner: Can the ISA be kept, and how are its underlying returns treated locally?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
UK pension / SIPP! Review / opportunity
UK private pension relief is not automatic
The current UK-Thailand treaty has no dedicated private pension article.
UK private pension tax can remain while Thai remittance rules also matter. Government-service pensions have separate provisions under Article 19. A specified LTR exemption needs its own eligibility assessment and is not supplied by an ordinary retirement visa.
Worth exploring: Coordinate withdrawals and supported credit claims rather than assume a tax-free pension.
Ask a planner: What UK pension category, withholding and Thai remittances apply?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
General investment account! High priority
Separate transferred capital from returns
Foreign portfolio income needs earning-year and remittance records, rather than a single rate on the account.
A sale transfer may contain principal and gain. Identify the taxable element and the year in which it arose, Thai residence then, and the amount brought into Thailand. Review available credit relief with evidence.
Worth exploring: Compare a documented withdrawal and remittance plan before adding another wrapper.
Ask a planner: Can the transfer be traced to original capital, income and realised gains?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
UK onshore bond! High priority
Review the onshore policy before withdrawals
Assess the local classification of your onshore or offshore investment bond. A UK withdrawal calculation does not determine the destination’s treatment.
Review policy gains, return of capital and the year of income before remitting proceeds. A foreign bond’s withdrawal label does not settle Thai tax. Check the specific insurer, payment type and any planned UK return. Track the earning year, Thai tax residence in that year and the nature of the remittance. Ordinary retirement residence does not establish the specified LTR foreign-income exemption.
Worth exploring: Compare a documented withdrawal and remittance plan before adding another wrapper.
Ask a planner: What is capital, what is a policy gain and which country can tax the payment?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
Offshore investment bond! High priority
Review the offshore policy contract
Assess the local classification of your onshore or offshore investment bond. A UK withdrawal calculation does not determine the destination’s treatment.
Review policy gains, return of capital and the year of income before remitting proceeds. A foreign bond’s withdrawal label does not settle Thai tax. Check the specific insurer, payment type and any planned UK return. Track the earning year, Thai tax residence in that year and the nature of the remittance. Ordinary retirement residence does not establish the specified LTR foreign-income exemption.
Worth exploring: Compare a documented withdrawal and remittance plan before adding another wrapper.
Ask a planner: What is capital, what is a policy gain and which country can tax the payment?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
UK operating business! High priority
Your move and your company are separate tax questions
Running a UK company from Thailand can create local company or permanent-establishment questions while UK obligations continue.
A UK incorporated company does not automatically stop being UK resident when its owner moves. Assess where decisions and work occur, then check the country treaty and local business rules.
Worth exploring: Review actual governance, operations and remuneration before changing the ownership structure.
Ask a planner: Where will the business actually be managed and operated?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
US accounts
401(k)! Review / opportunity
Assess the existing 401(k) distribution plan
Pension treaty treatment and Thai remittance rules both need applying to a 401(k).
Article 20 generally addresses qualifying private pensions by residence, including eligible US plans. Its saving clause can preserve US taxation of citizens. Thai earning-year and remittance evidence remain relevant, while government pensions and Social Security use different provisions.
Worth exploring: Compare retaining the existing retirement account and coordinating withdrawals before considering a transfer.
Ask a planner: How would each 401(k) distribution be treated in both countries?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
Traditional IRA! Review / opportunity
Classify each traditional IRA withdrawal
IRA treaty classification does not remove the need to check US status and Thai remittances.
The treaty explanation includes individual retirement accounts in qualifying private pensions. US citizens may remain taxable through the saving clause. Check each payment, the remittance trail and any narrow LTR exemption.
Worth exploring: Compare retaining the existing retirement account and coordinating withdrawals before considering a transfer.
Ask a planner: Which part of the IRA withdrawal is taxable, and how is it classified locally?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
Roth IRA! High priority
Will the Roth treatment travel with you?
A qualified US Roth distribution is not automatically exempt from Thai remittance taxation. Classification and treaty review are needed.
Identify capital and income elements and the relevant earning years. Do not assume US tax-free treatment travels unchanged. Track the earning year, Thai tax residence in that year and the nature of the remittance. Ordinary retirement residence does not establish the specified LTR foreign-income exemption.
Worth exploring: Review the existing Roth before making transfers, conversions or replacement arrangements.
Ask a planner: Does the exact account and payment qualify for destination relief?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
US brokerage account! Review / opportunity
Trace remitted investment income and gains
Thai remittance rules may apply to foreign returns while US taxpayers also face US investment taxation.
Document income, sales proceeds, capital and foreign tax. Check how credits apply rather than assuming tax paid in the US resolves Thailand automatically. US taxpayers should check non-US funds for PFIC requirements before changing investments. Track the earning year, Thai tax residence in that year and the nature of the remittance. Ordinary retirement residence does not establish the specified LTR foreign-income exemption.
Worth exploring: Compare a straightforward US-compatible portfolio with the costs of added wrappers.
Ask a planner: Which transfers are taxable income rather than capital?
Sources & conditions
Checked 2026-10-19. Conditions apply; no personal eligibility decision.
International structures & other assets
International trust! High priority
A trust needs a personal review
The deed, settlor, trustees and beneficiaries determine the questions to investigate.
Review local attribution, distributions, source and succession. A US person may have foreign-trust reporting and tax obligations. This tool assigns no trust tax rate or saving.
Worth exploring: Compare the existing trust with simpler ownership only after reviewing the deed.
Ask a planner: Who controls the trust and who can benefit before and after the move?
Sources & conditions
Checked 2026-10-19. Personal review only.
International pension / QNUPS! Review / opportunity
Recognise the pension before modelling a benefit
An international pension or QNUPS needs scheme-specific review.
Foreign pensions need earning-year, residence and remittance evidence. A QNUPS label does not supply an exemption; any LTR relief depends on the eligible status and income. For US persons, foreign-plan recognition and reporting need separate checks. No numerical saving is assigned.
Worth exploring: Retaining existing accounts remains a valid comparison where another structure adds costs.
Ask a planner: What legal recognition and treaty treatment apply to the scheme and payments?
Sources & conditions
Checked 2026-10-19. Personal review only.
Overseas holding company! High priority
Review the entity and actual management
Foreign incorporation alone does not establish the combined tax result.
Separate Thai work, local business and foreign-company remittances. LTR foreign-income relief does not turn Thai-source operating income into exempt foreign income. US owners also need foreign-company reporting and classification review. No numerical saving is assigned.
Worth exploring: Consider a company only where its commercial and planning benefit justifies the obligations.
Ask a planner: Where is the entity managed and which people own or control it?
Sources & conditions
Checked 2026-10-19. Personal review only.
Other / overseas asset! Review / opportunity
Bring this asset into the planner discussion
Other overseas accounts are recorded without an automated tax assessment.
The tool has not researched this specific contract. Its legal jurisdiction, owner, rights and payment records need individual review, including any continuing US obligations.
Worth exploring: Use the map to prepare a focused review rather than infer treatment from another account.
Ask a planner: What documents establish the asset’s legal form and the owner’s rights?

Checked 2026-10-19. Personal review only.
