This thread is really helpful!

I'm in a rather different situation. I'm a Malaysian but not in Malaysia, and by the tax definition I'm a "non-resident". I work in a foreign country and they pay me for my services, but I am curious to know this (in all cases, I work overseas)

Assumption A: I sign an individual work contract in this country with my employer, as an individual
1. If they pay me in this country, I pay personal tax here (which is more than 30%). That's obvious.

Assumption B: I sign a service contract between my sole proprietor company & my employer
2. I have a sole proprietor company registered in Malaysia. What happens tax-wise if my sole-prop company bills my foreign employer (in lieu of salary), invoice from Malaysia for services rendered outside of Malaysia? What tax do I pay?

Assumption C: I sign an individual work contract in Malaysia with my foreign employer, as an individual
3. Next scenario, what if my employer pays me as an individual for services rendered outside Malaysia, but the payment method is TT to a Malaysian bank account?

I understand that sole proprietorship means that I'm taxed as an individual. But I'm unable to find information what happens if I'm a non-resident, no one seems to know which category I'm in. Do help!

You don't care whether the service is exported or not.
It is always depends where the income is derived.
You make a deal in Malaysia and delivered goods/services to overseas customer, it is still deemed income derived in Malaysia.
If not, all export company don't need to pay tax already. So the word "export" is irrelevant.

Non-tax resident still needs to pay tax one, as long as income is derived in Malaysia.
While for Italy, then you need to look on their specific ruling on non-tax resident, whether it will be charged as witholding tax or whatever.
