I have more accounts than you - I lived in THailand up to Covid and now don't spend more than 180 days - used used to pay tax every year - You file your own form and they then tell you how much tax you need to pay or get rebated.... - however recently I have been asked to give details and mobile phone numbers. - So you may not need to pay tax but you may have to prove that to the bank - there is currently a clampdown on such things.
you will soon as all banks are checking their accounts and account holders are required to declare foreign banks and income - it will of course take time.
Burak Kurt I've not done a DTV. If you already have the visa you are allowed multiple entries....maxumum stay of 180 days? So that would require just keavu g and returning to re-activate your visa. As I understand it, if you hold a DTV, you can leave and re-enter Thailand as many times as you want without having to apply for a re-entry permit.
If you haven't got a DTV yet, the best way is to get one online - it requires proof of funds. - at least 500,000 Thai Baht
Ok..if you need a visa, then you must go to the consulate or Embassy that issues them. E.g Laos, Vientiane or Savannakhet. Or Cambodia or Penang or even Singapore.
Otherwise just pick a border, stay in the other place overnight and come back
Don't forget it isn't a race, you can take your time ymto visit the other country
