Canada has long been one of the most popular destinations for British expats and foreign nationals around the world looking to relocate, owing to the high quality of life, diverse career opportunities for professionals, and stable political backdrop, but, as with any international destination, understanding how taxes work is essential for expats with incomes or assets across borders.

The double tax treaty between the UK and Canada is a bilateral agreement that prevents citizens and residents of either country from being taxed twice on the same income, and its provisions can have a significant impact on wealth management.

Our Canadian team based in Toronto has compiled the ten questions they most often encounter, providing a concise guide to double-taxation regulations for prospective expats or those already living in Canada.

What Is the Purpose of the UK-Canada Double Tax Treaty?

The tax treaty ensures the same rules and standards apply to British and Canadian citizens living in either country. Its main role is to clarify where an individual is a tax resident, and which tax office has the right to levy taxes on certain income.

For example, expats with employment income, investment returns and pensions originating overseas may need to apply the treaty rules to ensure they don’t pay tax in both countries, and apply the right credits, allowances and exemptions to avoid an unnecessarily high tax burden.

Does Canada Have a Tax Treaty With the UK?

Yes, Canada and the UK have a long-established treaty, and there are around 90 other treaties in place with jurisdictions including the US, Australia, France, India and Germany, although the provisions in each agreement are not identical.

How Does the Tax Treaty Influence My Tax Residency Position in Canada?

Tax residency is a fundamental reason tax treaties exist, and they set out the rules and criteria that categorise expats as either a tax resident or a non-tax resident, noting that this is an entirely different assessment than being a physical resident or holding a specific visa type. The treaty looks at:

  • Where your permanent home is based
  • The location of your immediate family members
  • How long you have lived in/intend to stay in Canada
  • Where your main income or assets are held
  • The country where you spend the most time (183+ days or six months of the year)

In some situations, expats who hold temporary visas may well be classed as tax residents, which means they become subject to Canadian tax on their worldwide incomes and assets.

If there is uncertainty, the treaty also sets out ‘tiebreaker’ rules to ensure there is consensus about where you are, and are not, a tax resident.

Why Might the Double Tax Treaty Impact My UK-Based Income?

If you are a Canadian tax resident, incomes arising in the UK, whether from employment, rental earnings or a pension, will technically be taxable in Canada. However, this depends on the specific type of income, and the rules set out which country taxes each source of revenue and at what rate.

When there are duplicate liabilities, such as the UK’s non-resident tax for landlords, treaty provisions need to be claimed to offset the second charge, usually as a tax credit.

What Are the Employment Income Tax Rules for UK Nationals Living in Canada?

Generally, your income from either Canadian or British employers will be taxed in Canada, assuming you are a tax resident, but again, this isn’t universal.

There may be situations where some foreign-sourced salaries are exempt, or where reliefs are available if the income has already been taxed at source.

How Can Property Owners Manage Rental Income Declarations as Canadian Tax Residents?

Cross-border property ownership may be common, but it’s also a stumbling block for expats who aren’t familiar with their reporting obligations or who discover that, in theory, rental income from the UK is taxable in both countries.

Usually, rental income is taxed in the country where the property is based, but again, you might need to report the earnings to both tax offices and submit a claim for a foreign tax credit if relevant.

How Are Pensions and Retirement Incomes Treated Under the Canada-UK Tax Treaty?

Normally, if pension funds are situated in the UK and pay benefits to tax residents living in Canada:

  • The British national needs to apply to HMRC to ensure tax isn’t withheld at the point of payment
  • Pension income is then declarable and taxable in Canada

However, this can vary with some pension fund structures, which is why professional guidance is always advisable when managing cross-border retirement income.

Can British Nationals Claim Tax Reliefs While on a Temporary Permit or Visa?

Yes, double tax treaty rules apply in the majority of circumstances, and if you’re living in Canada on a non-permanent basis, but still qualify as a tax resident, you’ll need to ensure you understand the UK-Canada treaty if, for example, you need to claim tax credits.

Likewise, the tiebreaker rules might come into play if you’re unsure whether you are a tax resident of one country, have family and economic ties to both, or if you split your time equally.

How Does the Canada Revenue Agency Tax Capital Gains for UK Expats?

Citizens of any country who become Canadian tax residents are subject to tax on their worldwide capital gains, although, owing to the inclusion rate, only 50% of gains are taxable.

Expats should note that gains or incomes that aren’t taxable, like ISA earnings, are taxed in Canada as any other type of income, and that UK-based assets are generally assessed at fair market value for tax purposes.

Do Tax Treaties Apply to Remote Workers and Digital Nomads Living in Canada?

Potentially, yes, and the rising demand for remote working visas often means that digital nomads become tax residents, sometimes without realising it. The treaty covers scenarios where individuals may have uncertain tax obligations or risk incurring duplicate tax liabilities due to cross-border working arrangements.

Further Guidance on the UK’s Tax Treaty With Canada

Navigating the Canadian tax system can seem complex, but the double tax treaty offers protection against duplicate tax provided the rules are applied correctly, and you ensure you submit the right returns and declarations in each jurisdiction according to the relevant tax regulations.
