Do I file in both Canada and Hong Kong?
Usually yes, at least for the transition year. Outbound clients need Canadian residence properly ended; inbound clients need Hong Kong-source income and any legacy company interests reported in Canada.
Which return do you prepare first?
Whichever one the credit depends on. Preparing them in the wrong order is the most common reason a credit is claimed in the wrong place, and it is also the most common reason a client ends up paying twice and reclaiming later.
Does the treaty mean I only file once?
No. A treaty allocates the tax; it does not consolidate the filing. Both obligations survive, and in some cases the treaty position itself has to be disclosed on a return before it can be relied on.
What about sub-national tax — states and provinces?
They set their own residency and sourcing rules and are not bound by the federal treaty in the same way. A position that is protected federally can still produce a state or provincial return, which is the single most common surprise in this corridor.
Can you work with my adviser in the other country?
That is how most corridor engagements run. They keep their side, we take ours and the interaction between the two, and the scope boundary is agreed in writing so nothing is duplicated or dropped.
What if I am behind in one country and current in the other?
That is the usual pattern. We map the unfiled years first and check which catch-up routes are open before anything is filed, because the route chosen for one year affects the relief available for the rest.
Hong Kong did not tax my income — do I still report it in Canada?
Yes, if you are resident in Canada. The two systems are answering different questions. Hong Kong charges on a source basis, so income that arose elsewhere can sit outside its charge altogether; Canada charges its residents on worldwide income regardless of where it arose or whether anyone else taxed it. Income being untaxed in Hong Kong is therefore not a conclusion about Canada. It is the reason a Canadian liability can arise with no foreign tax to credit against it. Plan for that, because the clients caught short at the Canadian deadline are the ones who budgeted on the Hong Kong outcome.
I moved to Hong Kong. When does my Canadian residence actually end?
On the date your residential ties to Canada were severed, which is a question of fact and rarely the date of the flight. The home, and whether it was sold, let at arm's length or kept available; where the spouse and dependent children live; accounts, licences, memberships and where personal property is kept all feed into it. Hong Kong does not supply a competing residence position in the way most countries do, because its charge is built on source rather than residence, so the Canadian ties analysis carries almost the whole weight. That makes the documentary record on the Canadian side more important here, not less.
Do I have to report my Hong Kong company to Canada?
If you are resident in Canada and hold an interest in a foreign company, reporting obligations generally attach to the holding itself, quite separately from whether the company has distributed anything or made a profit. Family holding structures built up before anyone moved to Canada are the usual source of trouble: the interests were arranged when there was no Canadian connection, nobody revisited them on arrival, and the first Canadian return says nothing about them. The answer is to map the structure — what is held, by whom, and through what — before filing, rather than discovering it in an enquiry years later.
What evidence shows where my services were actually performed?
Contemporaneous records, not a later reconstruction. Where a source-based system is asking where the profits or the services arose, the file needs contracts that name where the work is to be carried out, travel records, where negotiations and approvals took place, and where the people doing the work were physically located and for how long. The distinction matters because the same fee can be inside one country's charge and outside another's on nothing more than where the work was done. Build the record as the work happens; a sourcing position assembled from memory two years afterwards is much harder to sustain.
Is income earned outside Hong Kong still outside the Hong Kong charge?
That is the question a source-based system exists to answer, and it turns on where the profits or services actually arose rather than on where the payer or the bank account sits. A Hong Kong company can have profits that arose elsewhere, and a person present in Hong Kong can be paid for work done elsewhere. Neither outcome is automatic and neither follows from the invoice address. The analysis is evidential: what was done, by whom, and where. For a Canadian resident there is a second half to it, because whatever Hong Kong concludes, Canada still charges worldwide income.
I returned to Canada with a Hong Kong holding company — what now?
Start with a map of the structure before anything is filed: the company, what it holds, who the shareholders are, whether other family members hold interests, and what has moved through it since incorporation. Canadian residence brings both the income and the holding itself into the reporting net, and the treatment depends on what the company actually does rather than on what it was set up to do. Legacy structures often turn out to hold assets nobody has considered for years. It is far cheaper to map it in the first Canadian year than to unwind an incomplete filing history afterwards.
Is the sale of foreign property taxable where I live?
For a resident, yes — worldwide gains are taxable, and the gain is computed in your own currency, so the exchange rate at purchase and at sale changes the number even when the local-currency price did not move. The country where the property sits usually taxes it too, often with a withholding or clearance step before closing, and that tax becomes a credit. A principal residence relief may apply to a home abroad on the same terms as one at home. See principal residence and foreign property.
What is a totalization agreement and how do I use one?
A social security agreement that stops you contributing to two systems for the same work, and lets periods in both count towards benefit eligibility in either. Which system you stay in depends on the agreement's rules for your situation — a seconded employee usually remains in the home system for a set period, a locally hired one usually joins the host system. You evidence it with a certificate of coverage obtained before or shortly after the assignment starts. See certificates of coverage.
