The short answer

For most income, the cheapest route is to receive it in a UK account and send it on with a specialist provider such as Wise, which converts at the mid-market rate. Your State Pension can also be paid straight into a Thai bank account, with a 0.39% conversion charge — but in Thailand it's frozen at the rate when you first claim abroad. Avoid sending regular income by UK bank SWIFT transfer: the fee and exchange margin can cost five times as much.

If you're in Thailand for 180 days or more in a year, you're a Thai tax resident, and foreign income earned from 2024 onwards that you bring in can be taxable. Savings from before 2024 are protected if you can prove it. Keep clear records and take advice before you move large sums.

Your UK State Pension in Thailand

You can claim your State Pension from Thailand through the International Pension Centre, within four months of reaching State Pension age. It can be paid into a UK account or straight into a bank account in Thailand — your own, a joint account, or someone else's with their permission.

• Paid every 4 or 13 weeks, your choice. Payments abroad may arrive a day late around holidays.
• Converted into baht at the exchange rate on the conversion date, with a 0.39% conversion charge, if paid to a Thai account.
• Frozen in Thailand. It stays at the rate when you first claim abroad (or the rate when you move) and doesn't get the annual UK increases. Moving back to the UK brings it up to the current rate.
• Life certificates. The DWP sends one from time to time; return it promptly, signed by an eligible witness, or payments can be suspended.
• One country only. If you split the year between countries, you must choose one for payment.

Paying it straight into a Thai account is convenient and fairly cheap. Paying it into a UK account and sending it with a specialist provider gives you more control over when you convert, and keeps a clear UK record of what you received — useful for tax.

Workplace and private pensions

Most UK workplace and personal pensions pay into a UK bank account. Some will pay abroad, but often by SWIFT transfer with charges and a margin you can't control. For most expats the better arrangement is:

1. Keep the pension paid into your UK account. It's free, reliable and keeps your UK records simple.
2. Send a regular transfer to your Thai account with a specialist provider, timed a few days after the pension arrives.
3. Keep a buffer in baht so a bad exchange rate week doesn't force you to convert.
4. Check your UK tax code each year — pensions are taxed in the UK through PAYE.

If you're thinking of taking a lump sum, transferring a pension overseas or drawing down larger amounts, get regulated advice first. Large one-off transfers into Thailand also raise the Thai tax questions below.

The routes we'd use

For regular income, a specialist provider from your UK account is usually cheapest. These are the three we'd compare first.

Rent, salaries and savings

How Thailand taxes income you bring in

This is the part that changed most in recent years. The rules in force as of October 2026 are:

• You're a Thai tax resident if you're in Thailand for 180 days or more in a calendar year. Non-residents are taxed only on Thai-source income.
• Since 1 January 2024 (Revenue Department instruction Por. 161/2566), foreign income earned by a Thai tax resident is assessable in the year it's brought into Thailand — whichever year that is.
• Income earned before 1 January 2024 is protected (Por. 162/2566), but only if you can show which money is pre-2024.
• Tax rates run from 0% to 35%, with the first ฿150,000 of taxable income exempt, after allowances such as the ฿60,000 personal allowance.
• The UK–Thailand tax treaty affects some income. UK government service pensions are taxed only in the UK unless you're a Thai national and resident. Where both countries can tax, relief is usually available so you don't pay twice.
• Returns are filed on form PND 90 or 91 by 31 March for paper filing (8 April online) for the previous year.

Thai tax rates on taxable income

Thailand's progressive rates, applied after allowances and deductions. Amounts in pounds are approximate.

Forvis Mazars, Personal income tax in Thailand. At ฿44.38 = £1. Allowances and deductions reduce taxable income; whether foreign income is assessable depends on residence, when it was earned and when it's brought in.

The records to keep

Good records are your protection — for tax, for visa renewals and for the bank. Keep, for every transfer:

1. The source: which account and which income it came from — pension, rent, salary or savings.
2. When it was earned: especially whether it was before or after 1 January 2024.
3. The transfer confirmation: date, amount in pounds, amount in baht and the rate.
4. The Thai bank credit: your statement or passbook showing it arrived as an international transfer.
5. Annual statements: P60s, pension statements and UK tax calculations.
6. Days in Thailand: your entry and exit dates each year, to show your residence status.

Keeping pre-2024 savings in a separate account, and moving money from that account when you want to use it, is one of the simplest ways to make the distinction clear.

Income and your Thai visa

For a retirement extension, Immigration wants to see either money in a Thai bank account, monthly income arriving from abroad, or a combination. The income route generally needs ฿65,000 a month transferred into your Thai account from abroad, shown on your bank statement — so the way your pension arrives matters.

• Send the same amount each month, at least the required figure, on a similar date.
• Make sure it shows as coming from abroad on your Thai statement — ask your bank or provider how transfers appear.
• Keep the bank letter and statements your Immigration office asks for.
• Check local requirements — offices differ in what they accept, and rules change.

Two worked examples

Illustrations at ฿44.38 = £1. The specialist cost is an estimate; check the provider's calculator. The UK bank example assumes a £9.50 fee, a 3% margin and a ฿200 receiving fee.

Common mistakes

• Sending every payment by bank SWIFT — the fees and margin add up to hundreds of pounds a year.
• Mixing pre-2024 savings with new income in one account, so you can't prove which is which.
• Planning around the proposed exemption before it becomes law.
• Missing a life certificate, so the State Pension stops.
• Letting the UK account close, leaving pensions with nowhere to go.
• Transferring a lump sum on impulse without checking the rate, the paperwork or the tax.
