Anonymous participant 152 There's no link between visas and tax residency. Most longer term visas are over 180 days, and METV can also be over 180 days. This merely deems a person a "tax resident" which on its own does not mean that person is going to be taxed. There's too many variables and each individual is in a different situation.
When I enquired at CW in Bangkok they said it was the same as other extensions, so up to 45 days before and 1900 baht. Apparently I did read there was a scam in Phuket where extensions would cost 10,000 baht, although I figure this would be an agent jumping onto the bandwagon and looking for a quick buck!
