Not just bosses, I really started to think it is a tendency of Chinese culture ppl not to get informed by themselves and just follow whatever the “experts” tell them to do. Too mafan ofc knowing what to do.
I see this so much with my fiancée, she is smart goddammit, has all the tools to understand things, but just can’t be bothered and asks always to “the person” without reading anything.
Very dangerous
I think what probably happened is the tax office woman said to him ‘if justintaiwan doesn’t pay, then you will be liable cos you didn’t make deductions’ and now he wants to make retroactive deductions by getting me to pay the tax office. But keeping that part of the conversation to himself.
Instead of saying to himself ‘justintaiwan is more trustworthy than I am, I have nothing to worry about’ he’s gone down the path of being a pain.
Anyway I decided I’m just not going to see him at all. I’m too busy (I leave in two days) to deal with problems someone has given themselves
This is what I did when I left Taiwan to go work in China for a year. No issue when I returned.
Although I didn’t actually have any tax due, cos I left in August so was on resident tax rate.
I will have taxes due but they’re due in May each year. So even if I am liable for 18% on this years wages, I don’t need to pay until next May.
Turns out he already submitted a false declaration claiming he withheld tax. So they asked him to pay the money he said he withheld but didn’t. And so he asked me to pay it.
I just said that’s not my problem, I’ll pay my taxes in May. If he made false declarations that’s not my problem, it’s his.
It gets better. They said they can pay it first and I repay them next year.
I said sure thing, but then you need to correct my pension that you underpaid and stole from me for 2 years first.
Response ’we’ll sort it out’
What happened in the end? Did you file online with your husband as the main taxpayer?
Did the boss get his money?
Never heard from the boss. I filed online and changed the ‘withheld’ to 0 which is what actually happened
So when you left Taiwan, you didnt do anything?
Just filed online the following May?
My wife is worried because she remembers the signs at the tax office saying to file before you go
Yeah basically, was easiest.
I filed online with my husband as the ‘main’ taxpayer. Everything autofilled and the only change I made was changing the withheld to 0.
Should be the last Taiwanese tax return we do for the foreseeable future.
We’re doing our Australian taxes now.
Death and taxes 
Probably just fear mongering. You can file before you go if you want but there’s no need if you file online
They’d presumably need to make sure they have some way to file online from abroad though, if they’ve already canceled their NHI?
Citizen digital certificate?
Also when your NHI is cancelled you can still use the card with a card reader to login to TW gov stuff. I’ve done it
But I don’t think they’re proactive enough to make sure.
I actually didnt even think of that. 
Saying that, it isnt cancelled, it is just suspended when someone still has an ARC or APRC, isnt it?
Just applied for my digital alien citizen certificate as a precaution.
What about all those ROC nationals that live full-time overseas but come back every few years to renew their household registration? How are they not tax residents?
