Thailand visa financial proof differs per visa: from 20,000 baht for a tourist visa to 800,000 baht for retirement and 3 million baht for the O-X.

Last checked: 11 October 2026

In short (as of 11 October 2026)
At the embassy (list of The Hague, 31 August 2026): tourist visa 20,000 baht; Non-O for a Thai partner 40,000 baht per month or 400,000 baht; retirement (Non-O and O-A) 65,000 baht per month or 800,000 baht; DTV 500,000 baht on 3 months of bank statements.
Retirement extension in Thailand: 800,000 baht at a commercial bank in Thailand, at least 2 months before the application and 3 months after approval, then at least 400,000 baht; or an income of 65,000 baht per month; or a combination totalling 800,000 baht.
Extension with a Thai wife: 400,000 baht that has been in a Thai account for 2 months, or 40,000 baht per month, or a combination.
The Netherlands: the Dutch embassy in Bangkok issues a visa support letter for 50 euros (plus 2 euros postage). Belgium: no letter, but legalisation of your own declaration on honour, since 1 January 2026 in person only, 25 euros or 1,000 baht since 1 October 2026.
The combination of income and savings exists only for the extension in Thailand, not in the embassy's list.

This article is for Dutch and Belgian nationals who have to show that they have enough money or income for a Thai visa or an extension. The general Thai rules in this guide apply to all nationalities; the parts about embassies and documents are written for Dutch and Belgian passport holders, so if you hold another passport, check the requirements of the Thai embassy or consulate that serves you.

Thailand visa financial proof: two moments, each with its own rules

Financial proof (financial evidence) is asked for at two moments, with different rules:

At the visa application via thaievisa.go.th, assessed by the Royal Thai Embassy in The Hague or Brussels. As an example, the list usually names bank statements for the last 3 months or a sponsor letter; only for the O-X must the money be in a bank in Thailand.
At the extension in Thailand, assessed by the Thai Immigration Bureau. For savings this usually means an account at a bank in Thailand, with fixed periods before and sometimes after. Only for the DTV is a verifiable foreign account also accepted.

Amounts for the visa application

According to the document list of the Royal Thai Embassy in The Hague (31 August 2026), which uses the same categories as the e-Visa portal:

Visa (code)                             Financial proof
Tourist visa (TR)                       min. 20,000 baht
DTV                                     min. 500,000 baht, 3 months of statements,
                                        or sponsor letter
Non-B work (B1)                         min. 30,000 baht
Non-B business visit (B2)               30,000 (single) / 120,000 (multiple)
Non-O, non-Thai family (O7)             min. 30,000 baht
Non-O, Thai family (O8)                 40,000 per month or balance 400,000
Non-O, retirement 50+ (O2)              65,000 per month or balance 800,000
O-A, long stay                          65,000 per month or balance 800,000
O-X, 10 years                           see below
Non-ED, study                           tuition fees and living costs

For O2, O8 and O-A it is a monthly income or a current balance; the embassy list does not mention a combination.

O-X (10 years): according to the O-X leaflet of the Thai Ministry of Foreign Affairs (August 2024), at least 3,000,000 baht in a bank in Thailand, or at least 1,800,000 baht plus an annual income of at least 1,200,000 baht, after which you must have 3,000,000 baht in total in a Thai bank within 1 year of entry. The money stays in the account for at least 1 year; in the year after that at least 1,500,000 baht. The list of The Hague (31 August 2026) gives the same amounts. The O-X is available to 14 nationalities, including the Netherlands, but not Belgium.

Visa-exempt travel: the embassy in Brussels names at least 20,000 baht per person or 40,000 baht per family on entry.

Amounts for the extension in Thailand

Retirement (Non-O or O-A, aged 50 or over)

According to checklist 7-6 of the Immigration Bureau (November 2023) and Immigration Division 1 (Bangkok), one of three options:

Income: proof of a monthly income of at least 65,000 baht.
Savings: at least 800,000 baht at a commercial bank in Thailand, for at least 2 months before the application date and at least 3 months after approval. After that you may withdraw, but the balance must stay at least 400,000 baht.
Combination: annual income plus savings in a bank in Thailand totalling at least 800,000 baht on the application date, with the same savings rule before and after approval. The sources differ on the minimum after 3 months (see below).

For O-A only, health insurance of at least 100,000 dollars or 3,000,000 baht is also required.

Thai wife, child or family

According to checklist 7-4 (Thai wife) and Immigration Division 1, for the foreign spouse:

an average annual income of at least 40,000 baht per month, or
at least 400,000 baht at a commercial bank in Thailand, which has been there for the past 2 months, or
a combination of annual income and savings totalling at least 400,000 baht.

The same amounts apply to a parent of a Thai child. The Immigration Division 1 list for a foreign woman with a Thai husband contains no financial requirement.

DTV

For the extension of a DTV, Immigration Division 1 asks for at least 500,000 baht: in a Thai account, a verifiable foreign account, or both together, for at least 30 days before the application. Or a guarantee or employer's letter for at least 500,000 baht on the application date.

Parents of a student

At least 500,000 baht in an account in your own name at a bank in Thailand, for the last 3 months; for the first application at least 30 days.

The Thai bank account

Which bank: "a commercial bank located in Thailand or a specialized financial institution established under specific law" (Immigration Division 1).
Proof: a letter from the bank confirming the balance, plus a copy of the bank book. For the extension with a Thai wife, the bank book must be updated to the application date.
Opening an account: Immigration Division 1 issues a residence certificate (Letter of Residence), among other things for opening a bank account. If a branch turns you down, Immigration Division 1 recommends asking the bank's head office.

Proof of income from the Netherlands: the visa support letter

The Dutch embassy in Bangkok issues a visa support letter (visumondersteuningsbrief), which states that you have Dutch nationality and what your income is.

Cost: 50 euros, plus 2 euros for registered delivery by EMS (if applicable). If you pay cash, you pay in baht at the rate of the day.
How to apply: by email, by post or by appointment. First send an email to ban-ca@minbuza.nl.
What counts: income that can be verified with the Dutch Tax Administration (Belastingdienst). Bank balances, savings and transfers from a savings account do not count; rental income does.
Supporting documents: for example bank statements with monthly deposits, annual income statements (jaaropgaven) or pension statements, or a final tax assessment.
Processing time: by email or post about 10 working days; by appointment usually on the spot.
Validity: the letter has no period of validity; Thai immigration decides how old it may be.
No assessment: the embassy does not check whether you meet the income requirement.
Warning from the embassy: Thai immigration may stop accepting the letter in future; you would then have to meet what it requires instead, such as a sufficient balance in a Thai account.

Proof of income from Belgium: a legalised declaration on honour

The Belgian embassy in Bangkok issues no support letters for visa extensions.
Since 1 July 2021 it does legalise the signature on a declaration on honour (verklaring op eer) about your income, on presentation of supporting documents. The legalisation states that it concerns only the signature and says nothing about whether the content is correct.
Since 1 January 2026 this can only be done in person by appointment: you sign the document at the embassy in the presence of a consular officer. Applying by email is no longer possible (notice of 3 December 2025).
Cost since 1 October 2026: 25 euros or 1,000 baht per document; the embassy asks for payment in baht.

Costs

Euro amounts next to baht amounts are an indication, converted at the ECB reference rate of 9 October 2026: 1 euro = 37.574 baht.

Amounts (indication in euros)
   20,000 baht         532 euros
   40,000 baht       1,065 euros
   65,000 baht       1,730 euros
  400,000 baht      10,646 euros
  500,000 baht      13,307 euros
  800,000 baht      21,291 euros

Proof of income
 NL visa support letter          50 euros (+ 2 euros EMS)
 BE legalisation of declaration  25 euros or 1,000 baht
                                 (embassy charges 1 euro = 40 baht)

Common mistakes

Savings in a Dutch or Belgian account for the retirement extension. The extension requires savings in a bank in Thailand. The embassy list for the visa itself does not mention a Thai bank.

Depositing too late. For the retirement extension the 800,000 baht must be in the account at least 2 months before the application; for a Thai wife, the 400,000 baht for the past 2 months.

Withdrawing straight after approval. For retirement the money must stay in the account for another 3 months, and after that at least 400,000 baht must remain.

Declaring savings as income in the Netherlands. The Dutch embassy does not count bank balances and savings as income.

A Belgian declaration by email. Since 1 January 2026 only in person by appointment.

Where the sources contradict each other

Combination for retirement: the Immigration Bureau checklist allows withdrawals after 3 months down to 400,000 baht; Immigration Division 1 (Bangkok) writes that at least 50 percent of the original deposit must remain in the account. Ask your office which rule it applies.
Period before the application: the checklists of the Immigration Bureau (November 2023) and Immigration Division 1 name 2 months (retirement and spouse). The text of Police Order No. 327/2557 (2014) on the Immigration Bureau's website names 3 months for retirement, 60 days in the first year. A notice from the Belgian embassy of 1 March 2021 names "at least 3 months" for retirement and, for income, "regular deposits into a Thai account" for 12 months. The checklists are the most recent Thai source; ask your immigration office which period it applies.

What has changed

1 July 2021: the Belgian embassy now only legalises the signature on the declaration on honour, with a disclaimer.
November 2023: the Immigration Bureau publishes checklists 7-4 and 7-6 (dated 1 November 2023, page updated 24 November 2023).
1 January 2026: Belgian legalisation of self-signed documents in person only.
31 August 2026: The Hague publishes the updated list of financial requirements per visa.
1 October 2026: new consular fees at the Belgian embassy in Bangkok.
