I’m a dual citizen and going to be working remotely in Taiwan for a US company (company approved). I will still receive W-2 as normal. When tax season comes in Taiwan, do I just walk in to the tax office and give them my W-2? Is that sufficient for them to help me with my taxes? Also will my NHI be based off my tax return salary? I’m assuming I will be paying the monthly minimum until my salary is reported.
