. Officer NOT correct. Asking for the incountry non imm O (After tourist visa or visa exempt) the rule is to prove 800k฿ transfered INTERNATIONAL to a bank account in his name only. Then, with 30 days or less, he can ask for a year extension. If he wants to use the 800k฿ method only THEN it needs to be there 2 months before asking this extension.
"So my STV will come to an end". So you already had y'r two times extension of 90 days ? Or do you mean Single Entry Tourist Visa instead of Special Tourist Visa ?
. There is a half year long multi entry tourist visa ! You can stay max. 60 days in Thailand and then each entry gives you 60 day stay again. This for a half year. So if you leave Thailand just before the expire date and come back, you can almost 9 months from this visa.
So far I did it all by myself after I got this paper as an example from another Dutch guy.
I transfer every month an amount in Euro to my Bangkok bank account as international transfer. That transfer amount in Thai Baht, I print every month. I made a spread sheet with those 12 amounts (to caculate my tax) and go to the Revenue office. They fill in a so called PND91 with the total year amount and the deductions (100k฿ for everyone, 60k฿ per family (official) member, only me in this case and 190k฿ deduction because I am 65 year plus). First tranch in their system of 150k฿ is zero %. So I have a total deduction of 500k฿. If you transfer e.g. 700k฿ in a year, than it's only 5% next 150k฿ and 10% over the last 50k฿. Then I pay and buy a legal copy of that PND91 for 18฿ 🤭. With that I could get that RO22 document. In another Revenue office though 🙄. I only need this document every 5 year to get tax exemption in the Netherlands.
I needed a so called RO22 document. After paying (a bit 😉) tax in a revenue office, I could ask this document in another revenue office. For me at least, you cannot get it for coffee money.
