Thai Tax Planning.
The 2024 remittance rule, read against your actual income.
Who this is for
People who typically come to me about this.
Persona 1
Thai tax residents drawing UK or overseas pension income
180+ days in Thailand each year, pension income arriving from abroad, want to understand the new remittance rules.
Persona 2
New arrivals planning their first Thai tax year
Moved to Thailand recently or planning to. Want to establish residency cleanly and structure income from year one.
Persona 3
Cross-border business owners
Income from multiple jurisdictions, business interests in two or three countries, need a coherent multi-jurisdiction tax position.
What's involved
How the work actually plays out.
Thailand changed how it taxes foreign income remitted into the country from 1 January 2024. Spending 180 days or more in Thailand during a calendar year automatically makes you a Thai tax resident, potentially bringing foreign pensions, investment income and overseas withdrawals within the Thai tax net.
The rules depend on residency status, timing of remittances, double tax agreements and how income is structured.
The work here is to explain the rules clearly, examine your specific circumstances and structure withdrawals and remittances so as much of what you have earned as possible remains with you, legally, transparently and without unnecessary complexity.
The 180-day rule
You are a Thai tax resident in any calendar year in which you spend 180 days or more in Thailand. The bar is straightforward, the proof rarely is. Visa stamps, flight records, and bank statements are the documentation that gets asked for.
The remittance change
Until 2024, income earned in a prior year and remitted to Thailand in a later year was not subject to Thai personal income tax. The 2024 reinterpretation closed that loophole. Income remitted in a given tax year is now assessable in that year, regardless of when it was earned.
The double tax agreement between the UK and Thailand offers credit relief, but the relief requires filing. It is not automatic.
Common mistakes
Where this most often goes sideways.
Assuming the old prior-year structure still works.
The structure that worked for two decades stopped working in 2024. Planning that hasn’t been refreshed since the change is planning that has a problem.
Ignoring the double-tax credit mechanism.
The DTA relief is available but only if claimed and filed correctly. Many retirees pay Thai tax they wouldn’t owe because the UK tax already paid wasn’t properly credited.
How I work on this
The process, in three steps.
01
Document residency status
We establish, in writing, what your Thai tax residency is for the years that matter.
02
Map income sources
Where your income comes from, when it’s taxed at source, and what double-tax relief is available.
03
Sequence withdrawals
A written withdrawal sequence that accounts for the new rules, not a one-size-fits-all recommendation.
Fees and what to expect
Plain-English fee transparency.
I am paid through commission on the products arranged and an ongoing fee on the assets managed. Every cost, and what it pays, is set out in writing before you decide.
You may ask what any recommendation pays me, and the figures that apply are agreed in writing in the engagement letter before you proceed.
A first 30-minute consultation costs nothing and obliges you to nothing.
Client assets are held in your own name on FCA-regulated platforms or SEC-licensed brokers, never by me.
