Do I have to file at home while living in Hong Kong?
It depends on residence, not on address — except for US citizens and green-card holders, for whom the answer is yes regardless of where they live. We settle the residence question first, because every other answer follows from it.
Is there a treaty between my country and Hong Kong?
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 Hong Kong. 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.
Do I pay tax at home when I sell my Hong Kong flat?
That depends on where you are resident on the day the sale completes, not on where the flat sits. If your home system taxes residents on worldwide gains, a Hong Kong disposal goes on your home return like any other. The Hong Kong side is a separate question and turns on source: what the profit arose from and where the activity that produced it took place. The two analyses run in parallel and can both apply, so we settle the completion date and your residence position first, then look at whether any relief for tax paid on the other side is available to you.
Is a quick resale in Hong Kong treated as trading rather than investment?
It can be, and that is where a source-based system bites hardest. The question asked is not simply whether you are resident but whether the profit is a trading profit that arose in Hong Kong, and that is answered from evidence: how the purchase was financed, how long you intended to hold, whether you have done it before, what you did with the flat in the meantime. A single quick sale is not automatically trading and a long hold is not automatically safe. Build the file at the time of purchase, because reconstructing intention years later from bank statements alone is far harder.
What documents prove my purchase cost years later?
Keep the sale and purchase agreement, the completion statement from the solicitor, the stamping records, the bank transfers that funded the deposit and the balance, and the loan documents if a bank lent against the flat. Add anything capital you spend afterwards, with invoices rather than card statements. A home-country return will ask for cost in home currency, so keep the dated bank advice showing what was actually converted. Owners routinely arrive at a sale years on with a price and no paper trail behind it, and the cost side is the half that has to be evidenced.
Does the exchange rate change the gain my home return shows?
Usually, yes, and it surprises people. If your home system computes the gain in its own currency, it converts the cost at the rate on the day of purchase and the proceeds at the rate on the day of sale. A flat that sold for roughly what it cost in Hong Kong dollars can still produce a reportable gain, or a loss, purely on the currency movement between the two dates. This is why the dated conversion evidence matters as much as the price. We work the gain in both currencies so you can see where the difference comes from before anything is filed.
Should our family's Hong Kong company hold the flat instead?
It is a real option and it is not free of consequences. Holding through a company moves the question from your personal position to the company's, and adds a second one: how you eventually get value out. It may also bring the shares themselves within your home country's reporting of foreign holdings, and disposals of shares are analysed differently from disposals of the underlying property. Decide it before the purchase rather than after. Restructuring an existing holding is a disposal in its own right in most systems, which is exactly the event the structure was meant to manage.
I rent the flat out while I am abroad — who taxes that rent?
Potentially both sides, for different reasons. Hong Kong looks at where the income arose, and rent from a Hong Kong flat has an obvious local source. Your home country, if it taxes residents on worldwide income, wants the same rent declared there as well. That double count is usually resolved by crediting one against the other rather than by choosing between them, and the credit is only as good as the evidence of what was actually paid. Keep the tenancy agreement, the agent's statements and the record of any local tax paid, in the year it was paid.
Is a gift from abroad taxable in Canada?
Not to the person receiving it — Canada does not tax gifts in the recipient's hands, whatever the amount. The tax questions sit elsewhere. A gift of property rather than cash is a disposition for the giver, at market value. Attribution rules can send the income the gift later earns back to the giver where the recipient is a spouse or a minor. And a gift large enough to be noticed should be documented, because "it was a gift" is a claim that gets tested. See a Canadian receiving a foreign gift.
How do Canadians reduce US estate tax exposure?
The treaty does much of the work: it gives a Canadian resident a credit pro-rated by the share of the worldwide estate made up of US assets, plus a marital credit that can defer exposure on a transfer to a spouse. Beyond that the levers are the ones you would expect — the domicile of the funds you hold, whether US real property is held directly or through a structure, and life insurance to fund the liability rather than reduce it. Worldwide estate value is what the pro-ration turns on. See treaty relief on US estate tax.
