What has changed
Four rule changes that affect Britons in Thailand
If you set up your pensions or your will before 2024, some of the assumptions behind them may no longer hold.
1 Jan 2024
Thai tax on money you bring in
If you are Thai tax resident (180 days or more in a year), foreign income you bring into Thailand is now generally taxable there, whichever year it was earned. Waiting a year before transferring no longer helps.
6 Apr 2025
IHT based on residence
Domicile no longer decides UK inheritance tax. If you were UK resident for 10 of the last 20 tax years, your worldwide estate can stay in scope for up to 10 years after you leave.
6 Apr 2026
Voluntary NI tightened
People abroad can no longer pay the cheaper Class 2 contributions, and you now need 10 years of past UK residence or contributions to pay voluntarily at all.
6 Apr 2027
Pensions in the estate
Unused pension funds and most death benefits will count towards your estate for UK inheritance tax. Now is the time to review nominations and drawdown plans.

Check My EligibilityFigures usedFull new State Pension 2026/27: £241.30 a week (£12,547.60 a year). Voluntary Class 3 contributions: £18.40 a week (£956.80 a year). You need 10 qualifying years to get any State Pension and 35 for the full amount. State Pension age 67. Thailand is not a country where the State Pension is uprated each year, so the amount is held at the rate when you first claim or move; the calculator shows today's rate. Assumes the new State Pension; people who reached State Pension age before April 2016, or were contracted out, may differ. Amounts before tax.

Help Me Avoid Double TaxFigures usedThai personal income tax bands, converted at about £1 = 44 baht (net income, approximate): 0% to £3,400, 5% to £6,800, 10% to £11,400, 15% to £17,000, 20% to £22,700, 25% to £45,500, 30% to £113,600, 35% above. Deductions: 50% expense allowance capped at about £2,300, personal allowance about £1,400, spouse allowance about £1,400. Assumes you are Thai tax resident and that pension income is assessed in the year you bring it in. Government service pensions are taxed only in the UK and are left out of the Thai figure. Ignores insurance and fund deductions, other income, foreign tax credits and the treaty position on individual pension types. UK figures use the 2026/27 personal allowance of £12,570 and 20/40/45% bands.

From 6 April 2027 unused pension funds and most death benefits count towards the estate. Transfers to a spouse or civil partner are exempt. Ignores gifts in the last 7 years, reliefs, and income tax beneficiaries may pay on pensions inherited after age 75. Thai inheritance tax only applies to inheritances above roughly £2.3 million, but Thai succession rules may still affect assets held in Thailand.

What we help with
Common Challenges British Expats in Thailand Face
UK State Pension in Thailand
Your State Pension can be paid into a Thai or UK account, but Thailand is not a country where it rises each year, so it stays at the rate you first claim. We check your forecast, when to claim through the International Pension Centre, and what a top-up is really worth.
"Will my State Pension be frozen in Thailand?"
National Insurance Top-Ups
Filling gaps in your record can still add a lot to your State Pension for a modest cost. We confirm whether you qualify under the new 10-year rule and help with the application (form CF83 or online).
"Is it worth paying voluntary contributions from Thailand?"
Thai Tax on UK Pensions
Since 1 January 2024, foreign income a Thai tax resident brings into Thailand can be taxed there. We map how the UK–Thailand treaty applies to each of your pensions, sort out your NT code with HMRC so tax is not taken twice, and plan what you transfer and when.
"Do I pay Thai tax on pension money I bring in?"
Inheritance Tax & Thai Wills
From April 2027 your pension can face UK inheritance tax, and Thai succession rules apply to assets you hold in Thailand. We review nominations, drawdown order and gifting, and coordinate a Thai will with your UK will.
"How much will my children actually receive?"
SIPPs, QROPS & Transfers
We compare keeping your UK pension, consolidating into an international SIPP, or transferring, with the 25% transfer charge, baht and sterling currency risk and Thai tax all counted.
"Should I move my pension out of the UK?"
Retirement Visa & Proof of Funds
Most retirees aged 50 and over stay on a retirement visa that needs ฿800,000 in a Thai bank, or income of ฿65,000 a month, or a mix of the two. We plan how your UK pensions and savings meet those tests alongside your tax position.
"How do I show enough income for my retirement visa?"

Frequently Asked Questions
Will I pay tax in Thailand on my UK pension?
If you spend 180 days or more in Thailand in a calendar year you are Thai tax resident. Since 1 January 2024, foreign income you bring into Thailand is generally taxable there, whichever year it was earned. How the UK–Thailand double tax treaty treats each pension type differs, and UK government service pensions (for example civil service and armed forces) stay taxable in the UK, so we check each of yours.
To stop HMRC taking UK tax from a private pension that is taxable in Thailand, you apply for an NT (no tax) code.
Does leaving the UK take me out of UK inheritance tax?
Not straight away. Since 6 April 2025, UK inheritance tax depends on residence, not domicile. If you were UK resident for at least 10 of the previous 20 tax years, your worldwide estate stays within UK IHT for between 3 and 10 years after you leave, depending on how long you lived in the UK.
Should I transfer my UK pension to a QROPS?
Moving a UK pension to a QROPS usually triggers a 25% Overseas Transfer Charge, unless you live in the same country as the scheme. Most British expats in Thailand have no suitable local scheme, so the real comparison is usually keeping the pension in the UK or moving it to an international SIPP. We compare each option for you, including the transfer charge, ongoing fees, currency and Thai tax, so you can decide with the full picture.
Will my UK State Pension go up each year in Thailand?
No. Thailand is not one of the countries where the State Pension is uprated, so it stays at the rate you first claimed or the rate when you moved. If you return to the UK, increases start again, but the rises you missed are not paid back.
Can I still pay voluntary National Insurance from Thailand?
Yes, but the rules tightened on 6 April 2026. People abroad can now only pay Class 3 contributions, and you need at least 10 years of past UK residence or contributions to qualify. Each extra qualifying year can still add around 1/35th of the full State Pension, so it is worth checking.
Do I need a separate will in Thailand?
Often, yes. Assets in Thailand are generally dealt with under Thai succession law, so many expats keep a Thai will alongside their UK will, worded so one does not cancel the other. Foreigners generally cannot own land in Thailand, and condominium ownership is subject to a foreign quota, so we work with Thai lawyers to make sure the plan fits what you actually own.
