Taiwan Immigrants and Canadian Tax Residency: 3 Costly Mistakes to Avoid

Why Taiwan-to-Canada tax planning is different

Canada and Taiwan have a tax arrangement — not a full tax treaty. This distinction is more significant than it appears. While the arrangement covers certain withholding tax rates on dividends, interest, and royalties, and includes residency tie-breaker rules for individuals with connections to both countries, it does not provide the comprehensive double taxation relief available under Canada's full tax treaties with countries like the United Kingdom or Australia. For individuals with Taiwan property, investments, or business interests who are becoming Canadian tax residents, this means that careful pre-arrival planning cannot be replaced by treaty protection.

Mistake 1 — Assuming residency begins when PR status is granted

Many Taiwanese immigrants believe their Canadian tax residency begins on the date they receive permanent resident status. CRA does not determine residency this way. Under the Income Tax Act, residency begins when you establish significant residential ties to Canada — typically when you arrive in Canada with the intention to reside, or when your spouse and dependants join you. PR status is a factor CRA considers, but it is not the sole determinant. Residency can begin earlier or later than the date on the PR card, depending on the actual facts of your situation.

Why this causes problems: If you arrived and set up a home in Canada before your PR was officially granted, your Canadian tax residency — and your obligation to report worldwide income — may have begun before you realized it. Conversely, if you obtained PR status but continued to live primarily in Taiwan for an extended period, your residency start date may be later than the PR date. Getting this date wrong — even by a few months — can result in retroactive assessments of worldwide income, including income from Taiwan during the period you were already a Canadian tax resident.

Mistake 2 — Misreading what the Canada–Taiwan tax arrangement actually covers

The Canada–Taiwan Tax Arrangement came into effect on January 1, 2017. It provides: reduced withholding tax rates on cross-border dividends (10–15%), interest (10%), and royalties (10%), residency tie-breaker rules for individuals with connections to both jurisdictions, and a framework for resolving double taxation disputes.

What it does not provide is automatic exemption from Canadian tax on Taiwan-sourced income. As a Canadian tax resident, you are taxed on your worldwide income — including rental income, dividends, interest, and business income from Taiwan. The arrangement reduces the Taiwan withholding tax rates on certain income, and you may claim a foreign tax credit on your Canadian return for Taiwan taxes paid. But the obligation to report and pay Canadian tax on Taiwan-sourced income remains. Misreading the arrangement as a broader exemption leads to consistent underreporting — and CRA has increasing access to international financial data through its information-sharing agreements.

Mistake 3 — Not filing T1135 in the first year of Canadian residency

T1135 (Foreign Income Verification Statement) is required for any Canadian tax resident who holds specified foreign property with an aggregate adjusted cost base exceeding CAD $100,000 at any point during the year. For Taiwanese immigrants, this threshold is commonly reached in the first year — often by a single Taiwan property, investment portfolio, or business interest. Common assets that trigger T1135 reporting include: Taiwan real estate held as investment (not principal residence), Taiwan brokerage accounts holding stocks or funds, Taiwan bank deposits and fixed income products, and shares or interests in Taiwan corporations or private companies.

The T1135 is due with your annual tax return (April 30 for individuals). Penalties for late or missing filings are automatic: $25 per day, up to $2,500 per year per missed filing. Gross negligence penalties can reach 5% of the cost of unreported assets. CRA's ability to detect unreported foreign assets grows every year through the Common Reporting Standard and bilateral information exchange — Taiwan financial institutions are now part of this network.

The most consequential T1135 error for newcomers is not late filing — it is failing to establish the correct adjusted cost base (ACB) for Taiwan assets at the date of entry. CRA treats certain property you owned before becoming a Canadian resident as having been acquired at fair market value on your date of entry. This deemed cost base becomes the starting point for all future capital gains calculations. An error made in the first year compounds into larger problems over time and is very difficult to correct retroactively.

Does this apply to your situation?

Early planning is significantly less expensive than correcting errors after the fact. Consider seeking professional advice before or shortly after arriving if any of the following apply:

• You are moving to Canada from Taiwan within the next 12 months
• You hold Taiwan property, investments, or business interests with a combined value over CAD $100,000
• You are uncertain about the date your Canadian tax residency actually began
• You have been splitting time between Taiwan and Canada and are unsure of your current tax status
• You have been in Canada for one or more years and have not filed T1135

Frequently asked questions

Does the Canada–Taiwan tax arrangement mean I won't be taxed twice on my Taiwan income?

The arrangement reduces the risk of double taxation but does not eliminate it automatically. As a Canadian tax resident, you report Taiwan income on your Canadian return and pay Canadian tax on it. If Taiwan has withheld tax on that income at source, you may claim a foreign tax credit on your Canadian return for the Taiwan tax paid. The credit reduces your Canadian tax owing, but you must report the income and claim the credit correctly — it is not automatic. The arrangement sets the maximum Taiwan withholding rates, which limits the Taiwan-side tax cost.

I moved to Canada but kept my Taiwan apartment as a rental — what are my obligations?

Your Taiwan rental property is likely a specified foreign property for T1135 purposes. If its adjusted cost base exceeds CAD $100,000, T1135 filing is required annually. The rental income must be reported on your Canadian tax return each year. Any Taiwan tax withheld on the rental income may be creditable against your Canadian tax. When you eventually sell the property, the capital gain is calculated from the ACB established at the date you became a Canadian resident — not the original purchase price.

I obtained Canadian PR but continued living in Taiwan for another year before moving. When did my residency begin?

Residency begins when you established significant ties to Canada — generally when you arrived to reside there, not the date on your PR card. If you maintained your home, family, and primary life in Taiwan during that period, your residency likely began when you physically moved and established ties in Canada. However, this is a facts-based determination. If you maintained Canadian ties (a home, a spouse already in Canada, Canadian bank accounts or employment) during the period you were in Taiwan, CRA may assess you as a Canadian resident for that period as well.

I've been in Canada for two years and haven't filed T1135 — what should I do?

If CRA has not yet contacted you regarding unreported foreign assets, the Voluntary Disclosures Program (VDP) may allow you to file late T1135 returns and significantly reduce penalties. Acting before CRA makes contact is the critical factor. The VDP was updated in October 2025 and now provides 100% penalty relief for unprompted disclosures, plus 75% interest relief. A confidential assessment can help you understand your exposure before committing to an application.
