They actually have two examples like that on the Australian website:
Example: Australian resident under the domicile test
Emily leaves Australia to work in Japan as a teacher of English. Emily has a one-year contract after which she plans to tour China and other parts of Asia before returning to Australia to continue work here.
Emily lives with a family in Japan during her time there and rents out her property in Australia. Emily is single. Her parents live interstate and her brother has moved to France. Emily is an Australian resident for tax purposes even though she is residing in Japan because, under the domicile test:
- her domicile is in Australia (as she is a resident who has lived in Australia and will generally retain a domicile here when absent overseas), unless she chooses to permanently migrate to another country)
- her permanent place of abode remains Australia.
Example: Foreign resident for tax purposes
Bronwyn, an Australian resident, receives a job offer to work overseas for 3 years, with an option to extend for another 3 years. Bronwyn, her husband and 3 children decide to make the move.
They rent out their house in Australia as they intend to return one day. While overseas they rent a house with an accommodation allowance provided under Bronwyn’s contract.
Bronwyn is unsure if she will extend her contract to stay for another 3 years. She will decide later depending on how the family like life.
Bronwyn is a foreign resident for tax purposes because she does not satisfy ‘the resides’ test. This is due to:
- the length of her physical absence from Australia
- other circumstances not being consistent with residing in Australia, even though she has retained the family home – such as
- establishing a home overseas with her family
- renting out her family home in Australia.
Bronwyn has also not satisfied the domicile test, as:
- her permanent place of abode is outside Australia due to
- the length of time committed to being overseas
- the establishment of a home overseas
- her family going with her overseas
- the fact that she won’t be selling the family home in Australia, although relevant, is not persuasive enough to overcome the finding on the basis of the other factors
- it can be argued that she has abandoned her home in Australia for the duration of her stay, by renting it out.
That’s, however, mostly the “standard case” - many countries handle it like that (similar things happen in UK, Germany, …). Taiwan is really the exception here.
And do note that some people on this forum actually argue that the current way Taiwan does things is actually beneficial for some: If they (as a foreigner) plan to stay less than 183 days per year, they don’t need to worry about “accidentally” becoming a tax-resident (especially for US-citizens this would cause double-taxation in some cases). Citizens need to be “more careful” about that as sometimes in extreme cases a single day in Taiwan could trigger tax residency.
So it’s less a discussion about what’s better in the individual situation, but more a question of general fairness and having those rules implemented without any discrimination.
