Yes I realise you are on the same page as me. Your initial post is pretty spot-on. Other posters here are making ludicrous claims that you can stay only 180 days per year, and each time you enter you pay another 10,000 baht. I'll bet these are people who have already paid the 50k for the LTR and are now melting down over this much cheaper alternative
Yes 90-day reporting still must be done. I'm in and out of the country constantly so I haven't filed a 90-day since covid. So for me there's the additional bonus of saving 3800 baht per year on a re-entry permit, as the DTV has five years of multiple entries.
Fortunately I have no Thai Driver's Licence, no vehicle registered to me, and have three bank accounts already. It's easy to get a TM30 if you should ever need one, but as there are visits to immigration under DTV, there's no-one else checking them.
The 14k is for five years multi-entry. That's 2800 per annum, with no requirement to transfer 65k each month and no requirement to visit immigration. That's easy enough for me to understand, even with my limited math! 😂
