It's your airline you need to fear.

It's often advised to check with them, which you could, but you could also safe yourself the time. Any airline will say that you are required to have proof of onward travel if you plan to use visa exemption. It doesn't mean that you will actually get checked.

@Randy *******

doesn't sound very realistic to me 🤷

There is no guarantee, but a second entry is relatively safe even if the first is maxed out.

@Neil ******

if it makes no sense to you, then you just shut up. Okay?

@Jack *******

yes sure, let's reply "I have no idea" and "nobody has an idea" and "nobody has any idea about anything you have and have not asked" to any topic, great 👍. Let's not help people. And make many assumptions about what others do not know.

@Neil ******

and if no tax was paid where it was owed, then that's not related to taxability in Thailand. That's between you and the country where tax was owed but not paid.

@Neil ******

the point is that if it's taxable, under whichever rule, it's determined by other factors than transferring 800,000 baht into Thailand. So if you become tax resident in Thailand in some way, perhaps by using a DTV, and if, as in your scenario, the money was indeed taxable, then it is still is if you leave it abroad. The unimaginably stupid rule that only remitted money is taxable is out of the window.

It's not income, so no.

guess again

@Neil *******

that is correct. It's no longer published as such by IATA but I don't think the actual rule has changed.

But keep in mind that proof of onward travel is required for the visa application instead when getting a tourist visa. So proof of onward travel is required (at any stage) whenever you come as a tourist. An embassy can however decide to still give you a visa even without proof of onward travel, they have discretionary right on it.
