If you are 50 or older and thinking about retiring in Thailand, there are three main visa options. The O-A visa requires 800,000 THB in a Thai bank or a monthly income of 65,000 THB. The O-X visa, available to people from 14 countries (including the United Kingdom, Canada, the United States of America, some European countries, and Japan), requires 3 million THB. The LTR visa requires US$80,000 in passive income per year, but it comes with the least paperwork once you get it. All three visas require health insurance and regular renewals.
Here’s what each option involves.
Which visa should you choose?
| O-A (1 year) | O-X (5+5 years) | LTR Wealthy Pensioner (10 years) | |
| Minimum age | 50 | 50 — restricted to 14 eligible nationalities | 50 |
| Financial requirement | 800,000 THB held in a Thai bank for at least 2 months, a monthly income of 65,000 THB, or a mix of the two adding up to 800,000 THB | 3 million THB in a Thai bank, or 1.8 million THB plus 1.2 million THB in annual income | US$80,000 a year in passive income, or US$40,000 a year alongside US$250,000 invested in Thailand |
| Insurance | US$100,000 (roughly 3 million THB) minimum cover, from a Thai insurer or an OIC-approved overseas provider | 40,000 THB outpatient and 400,000 THB inpatient as a minimum | US$50,000 in coverage, or a US$100,000 deposit maintained for 12 months |
| Renewal | Annual, with no limit on renewals | Five years, extendable once for another five | Five years, extendable once for another five; foreign-sourced income brought into Thailand is exempt from Thai tax |
If you are considering your options on Koh Samui, the O-A visa is usually the most practical place to start. It does not have any nationality restrictions and requires the least money upfront. Retirees from one of the 14 countries eligible for the O-X visa who have more capital can use that option to avoid annual renewals for up to ten years. The LTR visa is also worth considering if your passive income is over US$80,000 a year, but its tax benefits are not as large as many people think. More details on that are explained below.
O-A visa 101
This is the route most people use to retire on Koh Samui:
Check the basics. You need to be 50 or older on your application date, hold a passport valid for at least 18 months, and have no criminal record.
Get a police clearance certificate. Sourced from your home country, this can take 2 to 6 weeks and may require authentication from your foreign ministry before Thai embassies will accept it.
Get a medical certificate. A standard form confirming you’re free of a specific list of prohibited diseases, including Leprosy, Tuberculosis, drug addiction, Elephantiasis, and the third phase of Syphilis. You do not need a full medical exam.
Make sure your funds are in place. If you choose the bank deposit option, you need to have 800,000 THB in a Thai bank account for at least two months before you apply. The money must come from overseas.
Sort your insurance. You need a policy from a Thai insurer or a foreign insurer approved by Thailand’s Office of Insurance Commission, with at least 40,000 THB in outpatient cover and 400,000 THB in inpatient cover per year. Home-country travel insurance or public health cover won’t be accepted.
Apply. Either at a Thai embassy before you travel, or by converting an existing visa at an immigration office in Thailand. Retirees on Koh Samui usually handle renewals at the local immigration office.
Once granted, the O-A runs for one year and renews annually with no cap on the number of renewals, as long as you continue to meet the requirements.
Income or deposit?
Bank deposit (800,000 THB): This option is the easiest if you already have the money, but it will sit in a Thai account with very little, if any, interest. Immigration checks your balance at every renewal. If your balance drops below the required amount, even for a short time, your extension could be at risk.
Monthly income (65,000 THB): This option is good for retirees who want to keep their money invested outside Thailand. You will need either an income letter from your embassy in Thailand or 12 months of Thai bank statements showing regular deposits of at least 65,000 THB. Not all embassies provide income letters, so check with yours first.
Combination: If your monthly income is less than 65,000 THB, you can add savings to reach a total of 800,000 THB over the year. This is a good option for retirees with a modest pension and some savings.
O-X visa: what you need to know
The O-X is restricted to nationals of 14 countries. The US, UK, Australia, Canada, Japan, Germany, France, Italy, the Netherlands, Norway, Denmark, Finland, Sweden and Switzerland.
You’ll need 3 million THB in a Thai bank, or 1.8 million THB plus 1.2 million THB a year in income. The full amount must remain in the account for a year, then drop to a minimum of 1.5 million THB. Insurance requirements match the O-A: 40,000 THB outpatient, 400,000 THB inpatient.
In return, you get a five-year visa that can be extended for another five years, giving you up to ten years with much less annual immigration paperwork. This option is worth considering if you have significant savings and want to avoid frequent renewals while living on the island.
LTR visa: the wealthy option
The Wealthy Pensioner category under the LTR visa targets retirees with a substantial passive income, with pensions, investment income and rental income from abroad. The bar is US$80,000 per year, or US$40,000 per year plus US$250,000 invested in Thai property, government bonds, or direct investment. Insurance is US$50,000 of coverage, or a US$100,000 deposit held for 12 months.
Thailand’s Board of Investment separates LTR tax perks into two categories, so it’s important to know which one applies to you. Highly-Skilled Professionals get a 17% flat income tax rate. This is the number most retirement-visa articles mention. Wealthy Pensioners, on the other hand, receive a full exemption from Thai tax on any foreign-sourced income they bring into the country. This is a real benefit, even though it is not the one most people talk about. Along with the 10-year visa (five years plus a five-year extension) and yearly instead of 90-day reporting, the LTR is still a good option for retirees who meet the requirements.
Annual renewals, re-entry permits and 90-day reporting
Getting the visa is just the first step. It is just as important to stay compliant with the rules:
90-day reporting: You must confirm your Thai address with immigration every 90 days, either in person, by mail, or online. If you miss this, you will be fined 2,000 THB, and repeated misses can put your visa at risk.
Annual renewal. Start your appointment 30 to 45 days before the expiry date. You’ll need your passport, the TM.7 form, a recent photo, proof of funds or income, insurance paperwork and proof of address (TM30).
Re-entry permits: If you travel outside Thailand without a re-entry permit, your visa will be cancelled, no matter when it was set to expire. Make sure to get a single or multiple re-entry permit before leaving the island or the country.
Keeping the balance topped up. For the O-A, your bank balance must remain above the threshold throughout the year, not just at the time of application.
Common mistakes that get applications rejected
Funds seasoned too recently: Immigration carefully checks the two-month rule for the O-A visa. If you deposit the money just before applying, your application will not be accepted.
Insurance certificate incomplete. It needs the insurer’s signature and stamp, not a policy printout.
Balance falling below the threshold: If you spend the money in your account soon after approval and do not add more before renewal, your extension may be rejected. This is a common reason for applications being denied.
Applying for the wrong visa. Trying for an O-X when your nationality isn’t on the eligible list wastes both time and the application fee.
Forgetting the 90-day report: It is easy to forget this step, especially with the relaxed pace of island life. However, missing it repeatedly can lead to fines that add up over time.
Frequently asked questions
Can my spouse join me on a retirement visa?
Yes. A spouse can apply for a dependent Non-O visa alongside your O-A or O-X application, with a marriage certificate and the standard supporting documents.
Can I work in Thailand on a retirement visa?
No. The O-A, O-X, and LTR retirement visas all prohibit paid work in Thailand, including remote work performed for an overseas employer.
What if my income is in GBP, AUD or another currency?
No issue. Thai immigration converts to THB at the current exchange rate. Because rates move, it’s sensible to apply with a buffer above the minimum rather than exactly at the threshold.
Do I need a visa agent?
It is not required by law, but many retirees on Koh Samui choose to use one, especially since the island is far from the main immigration office in Surat Thani. An agent can help you avoid extra trips for small paperwork problems.
How often do the rules change?
The rules change regularly. Insurance minimums, financial requirements, and reporting rules have all changed in recent years. Always check the latest information with the Thai Immigration Bureau or your embassy before you apply.
This article was researched and fact-checked in July 2026 using immigration law firm guides and Thai embassy publications. Thai immigration requirements change periodically. Before applying, verify current thresholds directly with the Thai Immigration Bureau (ltr.boi.go.th) for LTR visas, or with your nearest Thai embassy or consulate.
