Expat tax in Thailand: What you need to know as a UK expat
Read our helpful guide to expat taxes in Thailand, including info on how British expats are taxed in Thailand and current personal income tax rates.
If you're planning a longer move, the Thailand retirement visa is one of the main ways to live in Thailand after 50. The visa you choose affects how long you can stay, what money you need to show, and what you must keep doing after arrival.
This guide covers the main visa types, the rules for UK applicants, extensions, and money admin. Our guide to living in Thailand as an expat can also help you picture daily life.
When you apply for a Thai retirement visa, this is actually an extended Non-Immigrant Visa based on retirement. There are two types: O-A and O-X.
O-A is the most commonly held and you can stay up to 1 year before renewing for another year. O-X allows you to stay up to 5 years before renewing for another 5 years.
Both visas allow you to choose single or multiple entry, depending on if you wish to stay in Thailand for the whole visa term or not. Bear in mind that you can't hold these visas and work in Thailand. UK nationals can apply for the O-X route.
For O-A, health insurance is also part of the application. Some official guidance refers to minimum cover of 40,000 THB outpatient and 400,000 THB inpatient, so check the latest Royal Thai Embassy London wording before you apply.¹
| Visa type | Main stay period | Financial route 1 | Financial route 2 |
| O-A visa | 1 year, renewable yearly | Bank deposit of at least 800,000 THB, approx £18,100 | Monthly income of at least 65,000 THB, approx £1,475 |
| O-X visa | 5 years, extendable for another 5 years | 3 million THB in a Thai bank, approx £68,000 | 1.8 million THB in a Thai bank, approx £40,800, plus annual income of at least 1.2 million THB, approx £27,200 |
If you qualify for O-X with a combined deposit and income, you must build the total to 3 million THB in a Thai bank within 1 year of arrival.¹
GBP figures are approximate and based on the exchange rate at time of writing — always check the current rate before making financial decisions.
To get a Thailand retirement visa, you need to be 50 or older and applying from the UK as a citizen or legal resident. The main requirements are:¹
The exact list can vary by visa type, but these are the documents most applicants should prepare:¹
Check the full list of documents on the Royal Thai Embassy London website before you submit anything.¹
The online flow is straightforward, but delays usually happen when documents are incomplete or uploaded in the wrong format.³
If you are already in Thailand on a 90-day Non-Immigrant O visa, you can usually apply for the retirement extension from within Thailand at an Immigration Bureau office.³
You might be wondering what happens when your visa runs out. Provided you still meet the requirements, you can extend it from within Thailand. Just visit the Office of Immigration Bureau in your province to file your application.³
For renewal, the 800,000 THB balance usually needs to have been in your Thai bank account for at least 3 months before you apply, compared with 2 months for the initial application.¹
Visa fees are set by the Royal Thai Embassy and may change, so avoid relying on older quoted prices.
Check the current fees on the Royal Thai Embassy London contact page before you apply.² Thai e-Visa fees are non-refundable once paid, which is why it is worth double-checking your visa category before you submit.³
Getting the visa is only part of the admin. After arrival, you still need to keep on top of a few rules:
If you become tax resident in Thailand, it is also worth checking how that interacts with your UK position. Our guide to expat tax in Thailand is a useful next step.
The O-A is the most common route, but it is not the only one. If you want less repeat paperwork or a different setup, two other long-stay options may suit you better.
The LTR Wealthy Pensioner route gives you a 10-year visa. It is aimed at people aged 50+ with passive income of USD 80,000 a year, or USD 40,000 plus a qualifying Thai investment of USD 250,000 in options such as government bonds or property. The main attraction is lighter reporting — you report annually instead of every 90 days.⁴
Thailand Privilege is a membership-based long-stay option. Current official packages run from 5 to 20 years, with 5-year options starting from THB 650,000 on the official site, no separate retirement income test, and perks such as airport fast-track services.⁵ If you're still deciding whether the move suits you, our guide to pros and cons of living in Thailand can help you weigh the trade-offs.
| Option | Duration | Min. age | Financial requirement | 90-day reporting | Working permitted |
| O-A | 1 year, renewable | 50 | 800,000 THB deposit or 65,000 THB/month income | Yes | No |
| LTR Wealthy Pensioner | 10 years | 50 | USD 80,000 passive income, or USD 40,000 + USD 250,000 Thai investment | No — annual report instead | Subject to permit rules |
| Thailand Privilege | 5 to 20 years | No specific age requirement | Membership fee only | Yes | No |
A common question is how to move the visa money without losing too much on exchange rates or bank fees. If you need to send the 800,000 THB deposit from the UK, or receive pension payments in Thailand, Wise lets you convert GBP to THB using the mid-market exchange rate, with fees shown before you confirm.
The Wise card can also be useful for day-to-day spending once you arrive. If your visa application or renewal needs proof that funds came from overseas, Wise can issue a FET letter for eligible transfers. You can read more in using Wise for long-stay visa applications in Thailand.
The O-A visa is usually issued for 1 year and can be renewed yearly if you still qualify. The O-X visa is longer, allowing a 5-year stay with the option to extend for another 5 years.¹
Health insurance is commonly part of the retirement visa process, but the exact requirement can depend on the visa type and the latest official guidance. Check the current Royal Thai Embassy London requirements before you apply.¹
No. Both O-A and O-X retirement visas are for long-stay retirement purposes and do not allow employment in Thailand.¹
For the O-A route, one option is a deposit of at least 800,000 THB. For O-X, the threshold is higher — starting at 1.8 million THB plus income, or 3 million THB outright in a Thai bank.¹
Yes, if you still meet the conditions, you can usually renew from within Thailand at the Immigration Bureau in your province. One important detail is that the bank balance for renewal must have been held for at least 3 months, compared with 2 months for the initial application.¹
