I've just used personal expenses and it is showing as Transfer from another a/c. I also tried 'other' and it is the same. These two transfers took seconds whereas when I chose 'buying property' it says Mon or Tues before funds arrive, and that is what I would expect.
Every tax resident can be investigated and if found to be evading tax they will be prosecuted but if found to owe no tax then no action will be taken. In Thailand, it is illegal to evade paying tax but it is not illegal if you don't file a return because you owe no tax.
Total rubbish. If an IO thinks you are not a genuine tourist then he or she can select you for secondary screening and you are then subject to all the petty rules that are not normally enforced. 20,000 baht in cash, proof of accommodation for the first 24 hours, and evidence of a return/onward flight within the initial visa-exempt period. If you comply with all these, they will tell you it is your last visa-exempt entry this year and mark your file. Even an official visa does not guarantee you entry as all entries are at the discretion of the immigration officer and that is the law!
There is no new rule. 180 days in any calendar year makes you a tax resident in Thailand and that has always been the case but you only have to file a tax return if you have a tax liability in Thailand. Eg, you earn money here, own shares or investments in Thailand or bring money onshore that has not been taxed under a double taxation agreement. Many ppl have had trouble at border points with multiple visa-exempt entries so it is best to use an agency to do a border bounce as they have agreements with border staff. Poipet border should be avoided as it makes its own rules.
The DTV can be extended for a further 180 days for 10,000 baht or simply leave and come back visa-exempt for 60 days which can also be extended for 30 days @ 1900 baht
