I'd suggest getting the DTV for you and your wife as soon as possible before they make it more difficult. It's like a 5 year freedom card! It can only get more restrictive from here.

With regards to paying taxes in Thailand, most expats who live here full time and pay no taxes to Thailand unless they are working for a Thai company. So, I wouldn't worry about taxation at all. If the gov't decides to start taxing those over 180 days/year, there will be many ways to avoid paying tax in Thailand while continuing to pay tax in your home country.

Print it on paper to hand over for the immigration officer to see. They will hand it back to you when they are finished. I just entered TH yesterday on the DTV. They didn't ask for anything else.

Did you need to show that it was paid in advance too or only booked?

I understand. Thank you Ellie.
