My certificate was all in Thai and only valid for 30 days. I have a yellow book and pink ID card, but rather difficult. Besides this Certificate, I needed a certified copy from my embassy in BKK from my passport, certified translation to Thai at Thai Ministry of Consulair affairs in BKK. Before I got it in my Amphur. But I read verry different stories about that. They wanted an original of the certificate, so that was the second after one needed for my drivers Licence. Good luck !!
Don't know for UK but Netherlands is 20 years for using them as usual. After that you can change them in "the Dutch bank" (government institute) eternal.
Most retirees have pension, which is mentioned in my first picture. All income (Pension IS an income) from abroad is tax liable. But okay, up to you. I have a big advantage of paying tax in Thailand
Paying Tax is something else than Tax liable in a country. If you bring money into Thailand, it is subjected to tax. However many treaties are made with Thailand "to prevent double taxation". I see also UK has one.
You type in uppercase letters as if it's a DISADVANTAGE paying tax in Thailand.
For me I pay tax about 10,000฿ a year in Thailand which exempts me of paying about 10.000€ (350,000 ฿) a year in the Netherlands.
, but costs a bit more. Also 'officialy' after 180 days in Thailand, you are tax liable in Thailand. I know not many pay and it's also depending if there is a tax treaty between Thailand and in thise case, UK. If the money comes in in a UK bank account, you can easy transfer money (And also the amount, again SHOULD you pay tax this can be handy 😉), with wise. So far I think this is best.
, it's a Special Tourist Visa. You can stay for 90 days and make an extension of stay two times for again two times 90 days. Look on the Thai Embassy website in the country you are/come from for the requirements. I thought this STV possibility will be ended September this year. (Don't know if this possibility will be extended)
Yes, IF you stay Consecutively 90 days or more in the Country (Which many times is, with the OA visa ofcourse). First time in person (almost always with TM47 form). After the first time it's possible to do it online.
