lololol. These folks are from Germany so your irrelevant comment has no meaning, but f it did, even before Trump's first term in office it was taking three months in the US to get a new, or renewed, passport.

if you are referring to a type O extension based on Thai wife, as a family visa (as there is no family visa), then a joint account is not accepted. That bt400,000 must be in your account in your name only for at least two months before you apply for your extension. For a retirement extension a joint account is only accepted sometimes at a few immigration offices if both are foreigners, and both applying for the retirement extensions. Joint accounts with a Thai person are not accepted. This is that way so you can't blame a Thai person for withdrawing money, and in doing so puts you below required funds in the account, even if you are married.

ok, you want to get into details. For this I'll use an American citizen as an example. Thailand expects you to pay your relevant income tax in your home country on income not made from business inside Thailand. Because of this, and the fact you do technically become a tax resident after 180 days in-country (this is nothing new), Thailand has dual tax treaties with many countries they trade with. The US has a treaty that sets equal tax amounts, and the tax you pay in your home country offsets all tax liability here on that same income earned outside Thailand in the case of an American. That is why I first mentioned Thailand trusts that you've paid your income tax in your home country. Thailand doesn't care, until you prove them wrong for trusting you to have paid your taxes.

Anonymous participant go to your local revenue office with your passport and DTV, and you will find out.

Anonymous participant technically maybe, but being that you are on a tourist visa that does not allow any work in Thailand, Thailand does not expect you to pay taxes in Thailand. You also will have a problem even getting a TIN, tax identification number, you must have to even file taxes, as revenue offices are not issuing them to tourists. Relevant country is your passport country, or the actual country your work is being done in. That is where Thailand expects you to pay relevant income tax. Tourists don't pay Thai income tax, and a DTV is a tourist visa.

You must have a treatment plan from your doctor. Past payments, and treatment, are not relevant, only what long term treatment is still medically needed in the future.

Anonymous participant no, it is not considered income in Thailand, as you did not physically work in Thailand. You only worked remotely, but Thailand does trust you to pay the appropriate income tax in the relevant country.

Be fully aware that from your past entry history if immigration determines you are trying to stay long term as a tourist they can refuse you entry whether you bought a tourist visa, or not. They become suspicious when someone buys a single entry tourist visa when they get the exact same entry time coming in on a free visa exempt entry. Both get a 60 day entry stamp, with the option to extend it by 30 days, so why would someone buy something they get for free?

Understand that if the embassy you apply at gets any notion you are not in the country they will ask you for a copy of every page in your passport, including all the blank pages.

At your age you should have some medical problem that a treatment plan could be drawn up for. There is a medical category for the DTV, and the resulting visa is no different than any other.
