The Number First
To extend a retirement visa (Non-Immigrant O-A or a one-year extension based on retirement) at Jomtien Immigration, which covers Pattaya, you must satisfy one of three financial thresholds:
- 800,000 THB deposited in a Thai bank account in your name, or
- 65,000 THB per month in provable pension or passive income, or
- A combination of both: if your monthly income falls between 40,000 and 64,999 THB, the shortfall must be covered by a Thai bank balance, so that the total reaches 800,000 THB equivalent for the year.
These figures are confirmed across multiple independent immigration sources as of mid-to-late 2026, including Thaiger (July 2026), Thai.Estate (August 2026), and Baan & Co (May 2026). They have not changed in recent years, but the way immigration scrutinises proof has tightened considerably.
The Three Routes, Compared
Route A: Lump-sum deposit (800,000 THB)
This is the most commonly used route because it is the simplest to prove. You deposit 800,000 THB into a Thai bank account, season it for the required period, and present your bank book and a formal bank letter at your appointment.
The seasoning requirement is the detail most people get wrong. For a first-time extension, the funds must be in the account for at least two months before the application date. For renewals, immigration expects the balance to have been maintained at or above 800,000 THB for the full preceding year, or at minimum for three months before the renewal date. Parking funds temporarily to hit the threshold and then withdrawing them is one of the most common reasons extensions are refused at renewal, when the 12-month bank statement is examined in full.
On the day of your appointment, bring to Jomtien Immigration:
- Your Thai bank book (original, updated to the day of the appointment at a branch)
- A formal bank letter confirming the balance, dated within the last seven days
- A 12-month bank statement (costs a few hundred baht, available from your branch within an hour)
Make sure your initial deposit came from abroad and carries an international transfer code. If it does not, ask your bank for a credit advice document to confirm the foreign origin of the funds.
Route B: Monthly income letter (65,000 THB/month)
This route works well for British, American, and Australian retirees whose embassies issue income affidavit letters routinely. You present an official letter from your embassy or consulate confirming your monthly pension or passive income meets or exceeds 65,000 THB.
The critical trap here is exchange rate movement. If your pension sits close to the minimum, a strengthening baht can push your converted income below the threshold by the time of your appointment. Build in a margin. If your income is borderline, Route A or the combination method is safer.
Note that Jomtien and Pattaya immigration offices also commonly ask for a pension certificate or additional income documentation alongside the embassy letter. Bring both.
Route C: Combination method
If your monthly income is between 40,000 and 64,999 THB, you can combine it with a Thai bank balance. The formula: 800,000 THB minus your annual income figure equals the minimum balance required in your Thai bank account. Both the income letter and the bank deposit evidence are required simultaneously.
What Changed Recently: The Apostille Question
A question circulating in expat groups in 2026 is whether a Hague Apostille can replace embassy legalisation for Thai visa documents. The short answer is: not yet. Thailand formally deposited its accession to the Apostille Convention on 30 June 2026, but the Convention does not enter into force for Thailand until 28 February 2027. Until that date, an apostille does not substitute for existing embassy certification or legalisation requirements. Follow your specific embassy’s current instructions and do not assume this has changed.
Health Insurance: The Mandatory Extra
For Non-Immigrant O-A holders, health insurance is mandatory. The minimum coverage required is 40,000 THB for outpatient treatment and 400,000 THB for inpatient treatment per year, from an insurer approved by Thailand’s Office of Insurance Commission. This is a separate requirement from the financial proof above and must be evidenced at every renewal. Verify the current approved insurer list directly with the OIC or your immigration office before applying, as this list is updated periodically.
What to Do This Week If You Are Approaching a Renewal
- Check your Thai bank balance today. If it has dipped below 800,000 THB at any point in the past year, note the dates and be prepared to explain them.
- Book a branch appointment to collect your 12-month bank statement and updated bank book.
- If using the income route, contact your embassy now. Embassy appointment slots for income letters can book out several weeks in advance.
- Confirm your health insurance policy is still on the OIC-approved list and that your certificate covers the renewal period.
- Do not rely on an apostille in place of embassy legalisation until after 28 February 2027.

FAQ
How much money do I need in a Thai bank account for a retirement visa extension in 2026?
800,000 THB must be deposited in a Thai bank account in your name. The funds must be seasoned for at least two months before a first extension, and maintained throughout the visa year for renewals.
What is the monthly income alternative to the 800,000 THB deposit?
65,000 THB per month in provable pension or passive income satisfies the financial requirement in place of the lump-sum deposit. Evidence is typically an official income letter from your embassy or consulate.
Can I combine income and savings to meet the Thailand retirement visa financial requirement?
Yes. If your monthly income is between 40,000 and 64,999 THB, you can top up with a Thai bank balance so the combined total reaches 800,000 THB equivalent for the year. Both income and bank evidence are required at the same appointment.
Does a Hague Apostille replace embassy legalisation for Thai visa documents in 2026?
No, not yet. Thailand’s accession to the Apostille Convention does not take effect until 28 February 2027. Until that date, existing embassy certification requirements remain in force.
What health insurance is required for a Non-Immigrant O-A retirement visa in Thailand?
A minimum of 40,000 THB outpatient and 400,000 THB inpatient coverage per year is required, from an insurer on the Office of Insurance Commission approved list. This must be evidenced at every renewal.
