Do I have to file at home while living in New Zealand?
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 New Zealand?
Possibly, and the version in force for your year is the one that matters — protocols and multilateral-instrument positions change what a treaty does without changing its name. We check it against the authority rather than a summary. Where no treaty applies, domestic relief takes over.
I own property in New Zealand. Where is the rent taxed?
In New Zealand, because that is where the property sits. The complication is the base: gross-rent withholding takes no account of mortgage interest, tax or repairs, so a leveraged property can face tax on turnover. An election onto net profit, where it exists, is what fixes that — and it has its own timing.
When do I stop being a Canadian tax resident if I move to New Zealand?
Residence ends on a date of fact, not on the date of the flight. What decides it is when your residential ties were actually severed: the home you lived in, where a spouse and children are, and the ordinary attachments that follow them. A move made in stages, with a house left available or family arriving later, often puts that date well away from the one you have in mind. Fix it first, because the part-year return, the value of what you owned on leaving, and the New Zealand side all hang off it. Gather the evidence for that date while it is still easy to obtain.
Do I file in both countries for the year I move?
Usually yes, and they are not the same return twice. The country you left taxes you as a resident up to your departure date and, after that, only on the income it still has a claim to. New Zealand picks you up from the point its own residence test is met. The two periods can overlap or leave a gap, because each country applies its own test to its own calendar. Where both charge the same income, relief comes through the treaty or through a credit rather than by choosing one country and ignoring the other. Work out the two periods before either return is prepared.
What is a transitional resident in New Zealand?
New Zealand has run transitional-resident rules for new arrivals, under which certain foreign income sits temporarily outside the charge. The practical consequence is that your arrival date opens a window, and that window closes. It matters most for people who intend to restructure something abroad after the move, because the same transaction can fall inside or outside the charge depending on when it happens. Identify the window before foreign assets are rearranged rather than afterwards, and check what the country you left will do with the same transaction, since a receipt that is quiet in New Zealand can still be taxable at the other end.
Should I sell my investments before or after I leave Canada?
Ceasing Canadian residence is treated as a disposition of much of what you own, so a great deal of the tax on an emigration is settled by the act of leaving rather than by any sale. That makes the sequence, not the sale itself, the thing to plan. Selling shortly before departure produces a real gain in a year you are still resident; holding through the move produces a deemed one and resets your cost for what follows. Some holdings are outside that rule and keep their history. Get the list of what you own reviewed before you book the move, because afterwards the date has already done its work.
I am a US citizen moving to New Zealand, do I still file?
Yes. United States filing follows citizenship, so becoming resident in New Zealand does not end it. You continue to report worldwide income, and your New Zealand employment, bank accounts and any local company interests come into that reporting. Relief for New Zealand tax is claimed through credits or an exclusion, and the two systems run on different year ends, which is what makes the arithmetic awkward rather than the principle. Information reporting on foreign accounts runs separately from the tax and carries its own consequences for being late, so it is worth confirming your position in the first year rather than the third.
What paperwork should I keep from the year I emigrate?
Keep what proves the date and what proves the values. The date is evidenced by the end of a lease or the sale of the home, the point employment ended, when the family actually moved, when licences and memberships lapsed, and when accounts were closed or redesignated as non-resident. The values matter because what you held on departure is treated as disposed of, and years later you will be asked what it was worth that day. Statements, valuations for property, and the employer paperwork covering the move are the three that are hardest to reconstruct later. Scan them at the time; nobody ever regrets the file.
How would a foreign tax authority know I am resident there?
Mostly from information you or your bank already provided. Account-opening forms ask you to self-certify tax residence, and that certification is reported between authorities under the Common Reporting Standard or, for US accounts, under the FATCA framework. Beyond that: employer and payroll filings, property registries, immigration records and the tax filings of anyone who paid you. The realistic planning assumption is that the data arrives. See FATCA and information reporting.
What is a double tax treaty and what does it actually do?
It is an agreement between two countries that divides up the right to tax. Article by article it decides which country taxes employment income, dividends, interest, royalties, pensions, property and business profits — and where both may tax, it caps what the source country can withhold and tells the other to give credit. It also breaks residence ties and opens a government-to-government channel for disputes. What it never does is apply itself: a treaty position is claimed. See our treaty work.
