Do I have to file at home while living in Taiwan?
Residence decides it, and residence is a question of facts rather than of where your post arrives. The one exception is US citizenship, which carries the filing obligation with the person wherever they go. So the first thing we establish is which system still claims you.
Is there a treaty between my country and Taiwan?
Treaty networks change with each protocol and each multilateral-instrument position, so we confirm the treaty in force for your specific year with the issuing authority rather than relying on a published summary. Where there is none, unilateral relief and domestic law do the work instead.
I own property in Taiwan. Where is the rent taxed?
Rent from immovable property is almost always taxable where the property is situated, frequently by withholding on the gross amount, with your home country taxing the same income and giving credit. A net-basis election, where one exists, is usually the difference between tax on profit and tax on turnover.
Is there a tax treaty between Taiwan and my home country?
Often not, and that single fact shapes everything else. Taiwan sits outside the treaty network that covers most of the region, so the analysis frequently proceeds on each country's domestic law and on unilateral relief rather than on a treaty article. In practice that means three things. There is no tie-breaker to settle dual residence, so both countries can apply their own tests and both can win. There is no reduced rate to claim at source, so withholding applies at the domestic rate. And relief for double tax comes from whatever credit your home country grants under its own rules, which is usually narrower than a treaty credit and has to be evidenced accordingly.
Does my Canadian or US filing continue while I work in Taiwan?
Residence decides the Canadian question and citizenship decides the American one. A Canadian who genuinely severs residential ties can become non-resident and file accordingly, but the test is about ties rather than distance, and a posting with the family and the home left in place usually does not sever them. An American citizen files regardless of where they live, for as long as the citizenship is held. Either way the Taiwanese tax paid does not cancel the home obligation; it is relief to be claimed, on a return that still has to be filed, with the Taiwanese assessment retained as the evidence supporting it.
How is my salary taxed in Taiwan if my employer is based elsewhere?
The starting point in most systems is that employment income is sourced where the duties are performed. So work carried out in Taiwan is generally within Taiwan's charge even if the contract, the employer and the bank account are all somewhere else. The employer's country may tax the same salary as well, as the source of the payment or on the basis of your continuing residence there. Without a treaty article to allocate between them, the resolution usually comes from the credit your home country allows for foreign tax, which makes the Taiwanese assessment and the proof of payment the most important documents in the file.
Do I have to report my Taiwanese bank accounts back home?
Very likely, and on a different footing from the income they produce. Many countries require the existence of foreign accounts and assets to be disclosed once holdings pass a threshold, separately from reporting the interest earned. The obligation attaches to what you hold, so an account that produced almost nothing can still be reportable. Penalties in this area tend to be fixed rather than proportionate, which means a small account can attract the same charge as a large one. The workable habit is to list every account opened on arrival, including salary and brokerage accounts opened for you by the employer, and to review that list at each year end.
What happens to my stock options when I move to Taiwan?
Equity is the most common source of double taxation in technology postings, because the reward is earned over one period and taxed at another. The usual approach is to look at the period between grant and vest, work out where the duties were performed during it, and apportion the income accordingly. A move in the middle of that period therefore splits a single award between two countries. The difficulty is that each country taxes at its own moment — some at vest, some at exercise, some at sale — so the same award can be taxed at different times as well as in different places. Map the grants before the move rather than at the first vesting date.
My employer is posting me to Taiwan — what should I sort out first?
Four items, before the flight rather than after it. What your residence position at home will be during the posting, and which ties you are keeping. Whether social security contributions continue at home or begin in Taiwan, and what evidences that. How equity already granted will be treated when it vests while you are abroad. And what documents you will need in order to prove the Taiwanese tax you pay, since the relief claimed at home stands or falls on that evidence. None of these is difficult in advance. All of them are awkward to reconstruct once a year of payroll has run on assumptions nobody wrote down.
Is my Indian provident fund or PPF still tax-free now that I live abroad?
The exemption is an Indian one, and it does not travel. Your new country of residence taxes worldwide income under its own rules, and several — the United States in particular — may treat the annual growth in a foreign retirement or savings plan as currently taxable and separately reportable, whether or not you withdrew anything. So an account that is genuinely tax-free in India can be a taxable, reportable asset where you now live. See Indian pensions received abroad.
How much foreign income is tax-free in the United States?
Nothing is exempt in the USA merely for arising abroad — a US person is taxed on worldwide income. What exists is an election: the foreign earned income exclusion removes foreign *earned* income up to an annual cap if you meet one of two qualifying tests, $132,900 for 2026 and $130,000 for 2025, with a separate housing amount alongside it. It does not touch investment income, pensions or gains, and it is claimed on a form rather than assumed. See the foreign earned income exclusion.
