Renouncing Canadian Citizenship: What Are the Tax Implications?

Renouncing Canadian citizenship is a different exercise from renouncing US citizenship. The US imposes a specific exit tax on covered expatriates (mark-to-market deemed sale under IRC 877A, with a $866,000 exclusion for 2023). Canada has no equivalent. There is no “expatriation tax” triggered by giving up Canadian citizenship. The Canadian tax consequences depend entirely on whether you are a Canadian tax resident, not on whether you hold a Canadian passport.

Does Canada impose an exit tax on renouncing citizenship?

No. Canada has a departure tax (deemed disposition of worldwide assets at fair market value on the date of departure), but it is triggered by ceasing to be a Canadian tax resident, not by renouncing citizenship. If you left Canada in 2023 and became a US tax resident, you already dealt with the departure tax in your 2023 final Canadian return. Renouncing your Canadian citizenship in 2026 has no additional tax consequence.

• This is the opposite of the US system. The US tracks citizenship independently: even if you left the US and became a non-resident 10 years ago, renouncing US citizenship triggers the exit tax (and Form 8854) at the time of renunciation. Canada simply does not have this mechanism.

What if I renounce while still living in Canada?

If you are living in Canada and renounce your Canadian citizenship (which is possible if you hold another citizenship), you remain a Canadian tax resident. Your tax obligations do not change. You still file a T1, pay tax on worldwide income, and report foreign property on T1135 if applicable.

• The only thing that changes is your immigration status: you become a permanent resident (if you have PR status) or a foreign national. Your tax residency is determined by where you live and your residential ties, not by your passport. Living in Canada with a Canadian address, Canadian bank accounts, and a Canadian spouse makes you a Canadian tax resident regardless of citizenship.

What if I renounce after leaving Canada?

If you left Canada, severed your residential ties, filed your final Canadian return (with the departure tax), and then later renounce your Canadian citizenship, the renunciation has no Canadian tax effect. You already became a non-resident when you left. The citizenship surrender is an immigration event, not a tax event.

After the renunciation, your Canadian tax obligations are the same as any other non-resident of Canada:

• Canadian-source income (rental income, pension payments, RRSP withdrawals) is subject to Part XIII withholding.
• You file a Canadian return only if you have income that requires a return (section 216 election for rental income, section 217 election for pension income, or a sale of taxable Canadian property under section 116).
• You are no longer eligible for Canadian-citizen-only benefits (voting, passport), but this is an immigration matter, not a tax matter.

What about the treaty tiebreaker?

The one area where citizenship matters for Canadian tax is the treaty tiebreaker. Under Article IV(2) of the Canada-US treaty, if a person is a resident of both countries under domestic law, the tiebreaker rules apply in order: permanent home, centre of vital interests, habitual abode, citizenship. If the first three tests are inconclusive (for example, the person has homes in both countries and spends significant time in each), citizenship is the tiebreaker.

• A dual citizen of Canada and the US who cannot be resolved by the first three tests and who renounces Canadian citizenship would be treated as a US resident for treaty purposes. This could trigger a Canadian departure (deemed disposition) if the treaty residence shifts from Canada to the US. In practice, this is a rare scenario because most tiebreaker cases are resolved by the permanent home or centre of vital interests tests.

How does this compare to renouncing US citizenship?

The differences between renouncing Canadian versus US citizenship are significant:

	Canada	US
Exit tax trigger	Ceasing tax residency (departure)	Renouncing citizenship or long-term residency
Tax base	Deemed disposition of worldwide assets	Mark-to-market on worldwide assets (IRC 877A)
Exclusion	Principal residence exemption, pension plans	$866,000 per person (2023, indexed)
Form	T1 final return + T1161	Form 8854
Ongoing obligations	Part XIII withholding on Canadian-source income	Covered expatriates face 30% withholding on certain deferred compensation
Timing	At departure, regardless of citizenship	At expatriation, regardless of when you left the country

The US system penalizes the act of renouncing. The Canadian system penalizes the act of leaving, regardless of whether you renounce. If you have already left Canada and paid the departure tax, renouncing Canadian citizenship is tax-neutral.

What should I do next?

If you are considering renouncing Canadian citizenship, the tax analysis starts with your residency status. If you are already a non-resident and have filed your departure return, there is nothing further on the tax side. If you are still a Canadian resident, renouncing citizenship alone does not end your tax obligations (you would also need to leave the country and sever residential ties to trigger the departure tax). If you are a dual citizen with a tiebreaker issue, the citizenship renunciation could shift your treaty residence.

• Canadian departure tax, the deemed disposition that applies when you leave
• Renouncing US citizenship exit tax, the US-side exit tax for comparison
• Dual-resident treaty tiebreaker, the tiebreaker sequence including citizenship
• Leaving Canada permanently: tax checklist, the full departure sequence
• Am I still a Canadian tax resident?, the residency determination
