Thailand proof-of-funds rule: what immigration can ask

On 6 July 2026 the Tourism Authority of Thailand issued a reminder that foreign visitors should keep evidence of sufficient funds ready for entry screening. It is worth being clear about what this is: a travel-preparation reminder, not a new measure.

How old is this rule?

The proof-of-funds requirement has been part of Thai immigration rules since a 1980 Ministry of Interior announcement, with the current amounts set by a later announcement in 2000. It is reflected in guidance from the Ministry of Foreign Affairs and from Royal Thai Embassies and Consulates-General, and Immigration Bureau officers apply it when assessing eligibility for entry.

The amounts

Depending on your entry category, you may be asked to show funds in Thai Baht, an equivalent amount in another currency, or documents evidencing payment of an equivalent amount.

• Transit Visa — 10,000 Baht per person, or 20,000 Baht per family.
• Visa on Arrival — 10,000 Baht per person, or 20,000 Baht per family.
• Tourist Visa — 20,000 Baht per person, or 40,000 Baht per family.
• Non-Immigrant Visa — 20,000 Baht per person, or 40,000 Baht per family.
• The requirement does not apply to children under 12.

What to have ready

Keep the documents accessible rather than buried in checked luggage. The other standing entry requirements are unchanged: a valid travel document, visa or visa-exemption eligibility, a permitted length of stay, accommodation details, and evidence of onward travel where required.

Being asked is uncommon for most arrivals, but the screening is real and it is applied at the officer's discretion. Supporting statements and booking confirmations can explain your plans, but are not a guaranteed substitute for a cash requirement.

Cash, supporting documents and examples

For the current tourist visa-exemption scheme, the Royal Thai Embassy in Washington specifies cash equivalent to 20,000 baht per person or 40,000 baht per family. The embassy in London also says officers may ask for evidence of 20,000 baht per person. This is separate from whether your passport qualifies for visa exemption. Read the guidance for your own entry category; do not apply the lower amounts for another category to a tourist visa-exempt arrival.

For example, a solo tourist using this exemption should prepare for the 20,000-baht threshold. A family travelling together should check the 40,000-baht family threshold and the conditions that apply to their circumstances. These illustrate the published amounts; they are not accounts of individual border decisions.

The Washington guidance specifies cash, including its equivalent in another currency. A credit card limit, an ATM card or a banking-app balance should not be assumed to satisfy that wording. Keep supporting statements available, but do not treat them as a guaranteed substitute for the published cash requirement. Ask the relevant embassy about an alternative before travelling if you cannot meet the stated requirement.
