How can I understand the visa requirements and proof of funds needed for entering Thailand?

bring money anyway you 'll need it if you are 3 persons .

What’s the point, the law says 20 k THB per person exchange the money before you live your country and you have no worries. If ask and you do t have the funds you have a problem to enter Thailand and then it will cost money.

It is 20K THB or equivalent per person or 40K per family, but your daughter is already adult. So you will need 3 times 20K = 60K.

Where do you come from? Normally you won't get visa on arrival, but a visa exemption.

If its your first time in TH ever or first in many months or years, more than likely you won't be asked.

The asking for this requirement is a tool they use to make trouble for people they suspect of basically living here long term on exemptions.

Noone will ask. And if they, for some strange reason would, you would 100% get a chance to prove that you have those sims available, just not cash.

I would never in my life carry that much cash when travelling.

40k for family

Thai Airports

BANGKOK, April 7, 2026 — Thailand has stepped up enforcement of a longstanding requirement for incoming tourists to show proof of sufficient funds, with authorities increasing spot checks at major entry points.

Under existing regulations, visitors entering on tourist visas or visa-exempt schemes must demonstrate they hold at least 20,000 baht ($550) per person or 40,000 baht per family. Those arriving on visa-on-arrival must show 10,000 baht per person.

The rule does not apply to holders of work permits, student visas or other long-term stays.

While the requirement has been in place for decades, immigration authorities have recently resumed more frequent checks, particularly at airports including Suvarnabhumi in Bangkok and Phuket International Airport.

Officials are increasingly asking travelers to present cash rather than relying solely on bank statements or credit cards, according to local reports.

Checks are typically focused on visitors with frequent entries, extended stays or irregular travel patterns, though first-time tourists may also be asked to provide proof of funds.

Failure to meet the requirement can result in denied entry, with travelers required to return at their own expense. Authorities accept major foreign currencies, including U.S. dollars and euros.

Thai officials said the renewed enforcement reflects routine immigration procedures and does not represent a change in policy.

So, unlikely to be checked ... but why risk it, unless the chance of an immediate return flight appeals?

The only time I was asked was 50 years ago traveling with a backpack.

I always bring all my money cash.

So whats the problem?

Surely you have 1500 bucks with you right?

40 k

You don't fall into the demographics of people likely to be checked

40k a family and 20k independently

the chances of being asked to show 20k are very slim.
