Businesses with cross-border operations should pay close attention to the latest proposed updates to Canada’s hybrid mismatch arrangement (HMA) framework.
The Department of Finance’s draft legislative proposals released on Jan. 29, 2026 contains the second package of new HMA rules. These measures—in conjunction with the initial package that was enacted in 2024—will complete Canada’s implementation of recommendations from the Organization for Economic Co-operation and Development (OECD) base erosion and profit shifting (BEPS) Action 2 report.
These measures are meant to prevent businesses with international presences from exploiting differences in countries’ tax systems to achieve mismatched tax outcomes, such as double deductions, on cross-border payments.
The new proposals apply to payments arising on or after July 1, 2026—including payments under arrangements entered into before that date.
As a result, businesses should review their cross-border arrangements, payments and structures to assess exposure. Restructuring ahead of the proposed effective date, in coordination with appropriate advisors, is another critical consideration.
Expanding the hybrid mismatch framework
The latest draft legislation extends Canada’s existing framework to account for hybrid mismatches arising from hybrid entities. It also amends key definitions such as hybrid mismatch arrangement and hybrid mismatch amount to incorporate new categories of mismatches.
The core mechanism of the primary and secondary rules enacted in 2024 remains unchanged. The primary rule generally denies a deduction where the payment is not taxed in the payee country, while the secondary rule requires the payment be brought into income if there is a deduction in a foreign jurisdiction for a non-taxable payment received in Canada.
The proposals also introduce concepts like dual inclusion income and investor dual inclusion income. They function as mitigating factors to prevent double taxation where cross-border structures with flow-through elements recognize receipts twice.
