the U.K. and Thailand have a Dual Taxation Agreement. If you pension has been taxed in the U.K. already, and you can prove it, it won't be taxed again in Thailand (However the tax you pay in the UK on the income you bring into Thailand can be claimed as a tax credit against Thai tax - you need to check this with the local Thai Department of Tax). Rest assured something like 600,000 THB per calendar year will be tax free after all the allowances have been deducted

you can enter on a 90-days Non-Imm-O Family visa, get stamped a 90-days stay permit, and on Immigration can get a 60-days extension based on "family visit" for 1900 Baht. Nobody is forcing you to extend your 90-days stay permit into the 1-year Extension of Stay Permit. However before the 90 plus 60 days = 150 days stay permit expires, you need to exit Thailand. You can't get another 60-days "family visit" extension any more - the limit is ONE per entry

Smithy Tee just a side reminder, because Ally's advice is NOT 100% correct: . . . . a foreign woman married to a Thai husband does NOT need to show any financial proof for the application to the 90-days Non-O family visa, nor for the application to the 12-months Extension on Immigration in Thailand

"especially if your wife needs to open a Thai Bank account to season funds in readiness for the extension 👍" . . . . . . sorry I think you have your wires crossed . . . . a foreign woman married to a Thai husband does NOT need to show a financial proof for the 90-days Non-O visa nor for the 12-months Extension

@Brian *********

after the 2 years out of a O/A visa, you must show the 800,000 THB in a Thai bank if you chose to continue to stay in Thailand on the yearly extension. So unless you return to your home country and apply for the 365-days Non-Imm-O/A visa again, there is no advantage

@Jesper ******

There is NO LIMIT . . . . . you can take out of Thailand an unlimited amount of foreign currency, you just need to declare it if is exceeds 15,000 USD. You are not allowed to take more than 50,000 Thai Baht out of Thailand

this comment shows the low level of your education - if you ever had one deserving this name 😂

@Wim ***

you should buy a pair of new optical glasses - it was 13,000 THB, not 3000 THB

use the "bank-to-bank" method offered by services like WISE, Western Union, Remittly or Revolut. Be careful: Do not use methods by credit csrds or cash payouts. ONLY use "home bank account-to-Thai bank account, in most cases by using the service provider's bank account as an intermittent. These is the less costly method and better than a direct SWIFT transfer from your home bank account to your Thai bank account

@Kevin ******

this won't happen when he shows up on a Non-Imm-O visa
