Can you stay 180 days on a DTV visa, exit, and re-enter within the same year, and what are the tax implications?

Every money you bring into Thailand (ATM withdrawals, credit card payments, etc.) has to be taxed if you stay longer than 180 days. There are tax-free allowances and similar rules. There are tax service companies that support you with the tax return and with applying for a tax ID.

If you are not tax-resident anywhere else, it can actually be beneficial to handle your taxes in Thailand.

In 2024 I brought more than 400,000 Baht into Thailand (via ATM, credit card, etc.), stayed in the country for more than 180 days, applied for a tax ID and filed the tax return.

I paid 4,000 Baht in taxes — so it’s really not much at all.

If you bring in only small amounts, you won’t have to pay anything..

That’s my experience for you to know..

Technically withdrawing money from an ATM and charging your “back” home credit card is a form of remittance! IJS… also I don’t think the Thai government is tracking small pototoes. IMO

The 180-day tax residency has always been a thing but only the last years has everybody been panicking about it. Being tax resident does not mean you have a tax liability. Only if you bring untaxed money onshore, earn money in Thailand or have investments in Thailand do you require a TIN and file a tax return, otherwise just enjoy your holiday in Thailand. As a tourist you are not even allowed a bank account so stop worrying about tax liability.

Tax is only on what you remit into thailand so its not really an issue, easy to avoid

With DTV the 180 day clock restarts every time you come back in. Unlimited times. You can only stay 180 days at a time. if more than 180 you'll need to get an extension.

I’m here to learn. Isn’t the way the DTV works is exactly what you stated? Stay for 180 days, leave and come back. Why would anyone have an issue?

Please forgive me if I am misunderstanding the question.

Hundreds have gone in and out. Even same day. As for tax it is based on 180+ days in country in calendar year + asessable income.

3 times flying in and out with DTV (soft power) and no questions asked at all upon entering again in Bangkok and Phuket

About taxes? I don't know / don't care. I don't remit any money here.

About staying throughout the year: I was here even before Jan 1st. and am still here, so it's possible. I've traveled here and then during the year to visit home, some 10 times or so, but always stays of a few days.
