Will Canadian citizenship change my tax return?
By itself, no. Canada taxes on residence, so citizenship is not a taxing connection: the same return is due on the same basis the day after the ceremony as the day before it. What changes your Canadian tax position is a change in where you live and what ties you keep, not the grant of the passport. That is worth stating plainly, because people often postpone tax questions until citizenship, expecting it to be the moment something happens. The moment that mattered came earlier, when residence began, and the next one comes if and when residence ends.
Do US citizens living abroad have to file every year?
Yes. The United States taxes its citizens on worldwide income wherever they live, so the obligation follows the passport rather than the address. Living and working in another country, bearing tax there, and having no US income does not remove the annual filing requirement, although mechanisms exist to relieve the same income being taxed twice and many people end up owing little or nothing. There are also reporting obligations on foreign accounts and holdings that are separate from the return itself. The practical failure here is rarely tax owed. It is years of returns nobody expected to be due.
My child was born in the United States — do they file?
If the birth conferred citizenship, the obligation attaches to the child in the same way it attaches to any other citizen, even if they left as an infant and have never returned. It usually surfaces in adulthood, when a bank asks about citizenship or a passport application is made, and by then there may be many years of unfiled returns and unreported accounts behind it. The position is retrievable, but the work is proportionate to the delay. If a child in the family was born there, establish whether citizenship followed before the question is asked by someone else.
Can I stop filing US returns by giving up citizenship?
Going forward, yes, but only through a formal expatriation, and that process has a tax regime of its own rather than being a matter of handing in a passport. Ending the obligation properly means the years up to that point have to be in order, and the accrued position in what you own may be brought into account at the exit. It is not a shortcut out of a filing backlog, because the backlog generally has to be dealt with first. Treat it as a planned project with a sequence, not as a single administrative act at a consulate.
Does dual citizenship mean paying tax in both countries?
It can mean filing in both, which is not the same thing. If one of the citizenships is American, the return is due on worldwide income wherever you live. If the other is Canadian, that passport creates no obligation by itself and your Canadian position turns on residence. So the common outcome is one filing obligation driven by citizenship and another driven by where you actually live, with relief mechanisms and, where it applies, a treaty deciding which country's claim comes first on a given item of income.
I became a Canadian citizen then left — do I still owe tax?
Not on the strength of the citizenship. Once you cease to be resident, Canada's claim narrows to Canadian-source income, and holding the passport does not extend it. Leaving has its own consequences in the year residence ends, and keeping certain ties can mean residence has not actually ended, so the facts need establishing rather than assuming. But the citizenship itself is not what keeps you in the system. This is where the contrast with the United States stands out, because there the passport would carry the obligation on its own.
Is double taxation illegal?
It is legal. Two countries can each have a valid claim on the same income — one because the income arose there, the other because you live there — and nothing prohibits both from exercising it. What exists instead is relief: tax treaties allocate the claim, and domestic law gives a credit for foreign tax paid. The relief is not automatic, though. It is claimed on a return, and unclaimed relief is simply lost. See how double taxation is relieved.
Do I pay tax when I inherit property abroad?
The inheritance itself is often not income to you, but three other things can create tax: the estate may owe tax where the deceased or the property was situated, some countries tax the recipient directly, and the gain from the date you inherit to the date you sell is yours. Reporting obligations can also attach to holding the asset. See inheriting property abroad.
