Dual Citizenship and Tax Implications in Canada 2025

Updated March 2025 · bremo.io

Canada permits dual and multiple citizenship. If you are a Canadian citizen who also holds citizenship in another country, you may have tax obligations in both countries. Understanding how each country taxes you — and how tax treaties reduce double taxation — is essential for proper financial planning.

Canada's Approach to Dual Citizenship

Canada has no legal restrictions on dual citizenship. You can be both a Canadian citizen and a citizen of most other countries simultaneously. However, Canada cannot protect you from the tax obligations of your other country of citizenship.

Canadian Tax Residency: Not Citizenship-Based

A critical distinction: Canada taxes based on tax residency, not citizenship. If you are a dual citizen living abroad, Canada does NOT automatically tax you. You are only subject to Canadian tax if you are a Canadian tax resident — meaning you have significant ties to Canada (home, spouse, dependents, bank accounts, etc.).

Leaving Canada: Severing Tax Residency

If you hold Canadian citizenship but move permanently to another country and sever your Canadian ties, you can cease to be a Canadian tax resident:

• Sell or rent your Canadian home
• Cancel or transfer provincial health coverage
• Close Canadian bank accounts or maintain only minor connections
• File a T1 return for the year of departure, noting your departure date
• Departure tax applies — deemed disposition of most assets at fair market value on departure date

The US-Canada Dual Citizenship Problem

The most complex dual citizenship tax situation for Canadians is holding US citizenship or a US green card while living in Canada. The United States is one of only two countries in the world (the other being Eritrea) that taxes citizens on worldwide income regardless of residence.

What US Citizens in Canada Must Do

• File a US federal tax return annually (Form 1040) reporting worldwide income
• File FBAR (FinCEN 114) if foreign financial accounts exceed $100 USD at any point in the year
• File Form 8938 (FATCA) if foreign assets exceed $200,000 USD
• Potentially file Form 5471 if you have foreign corporation ownership

Relief from Double Taxation: Canada-US Tax Treaty

The Canada-US Tax Convention reduces double taxation through:

• Foreign Tax Credits: Canadian taxes paid can offset US tax on the same income
• Exclusions: Certain Canadian government benefits and TFSA earnings may be excluded from US tax
• RRSP and RRIF: Treaty allows deferral of US tax on RRSP income until distributed

Other Common Dual Citizenship Tax Situations

UK-Canada Dual Citizens

The UK taxes residents (not citizens) on worldwide income. If you live in Canada, you are not a UK tax resident and generally not subject to UK income tax. The Canada-UK tax treaty prevents double taxation when you have income from both countries.

India-Canada Dual Citizens

Note: India currently does not allow dual citizenship — Indian citizens who take Canadian citizenship lose Indian citizenship. Persons of Indian Origin (PIOs) who are Canadian citizens may still have Indian-source income taxed in India. The Canada-India tax treaty reduces withholding tax on dividends, interest, and royalties.

Philippines-Canada Dual Citizens

Philippines allows dual citizenship for former Filipino citizens through the Dual Citizenship Act. Philippines taxes residents (not citizens abroad) on domestic income only. Filipinos living in Canada are generally only taxed in Canada, with Philippine-source income subject to Philippine withholding tax that can be used as a foreign tax credit in Canada.

China-Canada Situation

China does not recognize dual citizenship and may not acknowledge your Canadian citizenship when you are in China. Tax-wise, if you have Chinese-source income, the Canada-China tax treaty provides withholding tax relief and foreign tax credit mechanisms.

Departure Tax When Leaving Canada

When you leave Canada and cease to be a tax resident, the CRA deems you to have sold your assets at fair market value on the date of departure. This "departure tax" applies to:

• Non-registered investments (stocks, mutual funds, ETFs)
• Foreign property
• Certain other assets

Excluded from departure tax:

• RRSP and RRIF (taxed when withdrawn)
• TFSA (no Canadian tax, but may create foreign tax obligations)
• Real estate you owned while a Canadian resident
• Business property used in a Canadian business

Estate Planning for Dual Citizens

At death, Canadian residents are deemed to have disposed of all capital property at fair market value. This can trigger significant capital gains. Dual citizens whose other country also imposes estate or inheritance taxes face potential double taxation on their estate. Cross-border estate planning with specialists in both countries is important for those with significant assets.

Practical Steps for Dual Citizens

1. Determine your tax residency clearly — are you a Canadian tax resident?
2. Identify all countries that may have a claim to tax your income
3. Review relevant tax treaties with a cross-border tax specialist
4. Ensure you are filing all required foreign disclosure forms in Canada (T1135, etc.)
5. If you are a US person, ensure US tax compliance is up to date — the IRS Streamlined Filing Program exists for non-compliant US persons abroad
6. Plan large financial events (selling property, receiving inheritances) with tax implications in mind across all relevant jurisdictions

Banking With Dual Citizenship

FATCA (Foreign Account Tax Compliance Act) requires Canadian financial institutions to report accounts held by US persons (citizens or green card holders) to the CRA, which shares the information with the IRS. If you are a US-Canada dual citizen, your Canadian bank accounts are reported to the IRS. This is not something to hide from — ensure US tax compliance is maintained.

For day-to-day banking in Canada, no-fee options like KOHO work for all Canadians regardless of other citizenships held.
