In most cases when you reside more than 183 days in a country you are considered a resident for tax purposes. Depending on your remaining ties to your home country (assets etc.) you are definitely able to decide to pay tax in Thailand over the foreign income you transfer into Thailand. That's not related to a work permit and the revenue department is happy to give you a Tax ID

Good to know, thanks!

Yes I'm aware of that! Planning to use the service at Bumrungrad this Saturday since I live close by. I assume rejections for extensions are not common?

It's downstairs in the building next to the Consulate. Believe tbe building is called Lippo Center. In case you can't find it, go to the service counter of the consulate first, they will share the exact directions with you.

But wouldn't see why you don't switch to a better solution for both short and long term.

If you go along really well with your employer, maybe not.

Could be they require proof of monthly personal income tax payments by the company of those months when you actually cancel

@Amornrat *********

assume it can be that amount or more on a foreign account in USD or EUR? Need to go for my first SE next month..

Are you aware there's a 7 day margin after the stated reporting date?
