Hello, I’d like to deposit 250,000 THB in cash into my Thai bank account at Krungsri. Would this raise any potential tax issues?

If you live here over 180 days then you are considered a tax resident. There has been lots posted about these rules. Despite this, my answer is still I don't know. Thinking of moving some money over too so watching this space.

Assuming this is undeclared cash, depositing it is perfectly "safe" in that your Thai bank has no reporting duty of such a deposit amount to the revenue service.

It's basically cash from selling USDT, which is why I'm hesitant to deposit it. At the same time, keeping it in my condo feels risky, so I'm considering depositing it. 

No problem at all. My wife and I routinely deposit cash in amounts far greater than that (into Bangkok Bank and SCB). IIRC one time she deposited about 3 million THB and nothing was said.

Thank you so much for your answer!

Of course you will declare it as a remittance in 2025 tax return

How does one "declare a remittance"?

 

Perhaps it needs to be reviewed to understand if it might qualify as "Assessable Income"?

 

AFAIK there is no procedure form or requirement to declare a remittance.
