What should I know about the DTV visa's 180-day rule, extensions, and 90-day reports in Thailand?

Just either cross a border or do an extension, then you can stay all year round.

Here’s some clarification based on our experience assisting other DTV applicants:

180-day rule: Yes, with the DTV visa, you can stay up to 180 days in a calendar year. If you’d like to stay longer, the recommended approach is to exit and re-enter Thailand — even a short trip (e.g., 1 day) is usually fine. This allows you to get a new entry stamp for the following calendar year.

Visa extension: While it’s technically possible to apply for an extension at a Thai immigration office, we don’t recommend this. Your entire case will be reviewed again and often under greater scrutiny, which increases the risk of delays or rejection. A border run is much simpler and more predictable.

90-day report: Yes, if you stay in Thailand for 90 consecutive days, you’ll need to submit a TM47 form. This needs to be done in person each time you re-enter Thailand, there are several agencies that assist to do this reporting for you so you don't have to spend half a day waiting there.

Tax clarification: You are only taxed on foreign income remitted into Thailand. If you don't transfer money into Thai banks or use it in-country, it may not be taxed — but always best to seek advice depending on your setup.

Happy to share that we’ve assisted over 100+ DTV applicants so are quite familiar with the process. Feel free to ask anymore questions you have.

If you extend at an immigration office, you can stay the year without leaving but many find it easier to just do a border run and get a fresh 180-day stamp on arrival. The payment of tax depends on foreign income remitted into Thailand and you would need to seek advice if you would be liable to pay tax in Thailand. TM47 needs to be completed for the 90 day report.

Each entry on a DTV gets you stamped in for 180 days, each entry can be extended ONE time at immigration but to be honest your better just doing a border bounce to get another 180 days. If you spend 180 days or more inside Thailand in a calendar year then you are automatically a tax resident for that year and if you bring income into Thailand you need to complete a tax return. TM47 is the 90 day report form
