## What is the Global Minimum Tax (GMT)? - The GMT ensures that large multinationals (with annual global revenues over **€750 million**) pay **at least 15% effective tax** on profits in every jurisdiction they operate.([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/whats-new-corporations.html?utm_source=openai)) - **Canada’s GMT Legislation**, including the Global Minimum Tax Act, entered into law via Bill C-15 and related statutes. It implements the Income Inclusion Rule (IIR) and a **Domestic Minimum Top-Up Tax**, both effective for fiscal years **beginning on or after December 31, 2023**.([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/get-ready-file.html?utm_source=openai)) ## Key Entity Setup Considerations When structuring your entity or expanding operations, consider these strategic issues: - **Jurisdiction selection**: Jurisdictions with low effective tax rates may trigger additional top-up tax under either IIR or Domestic Minimum Top-Up. Entities must map all constituent entities and be transparent. Gathering jurisdictional ETRs is required.([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/get-ready-file.html?utm_source=openai)) - **Group reporting dynamics**: Canada’s new rules require multinational groups to file **GlOBE Information Returns (GIR)**, which include senior parent entity details and tax identification numbers for foreign affiliates.([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/get-ready-file.html?utm_source=openai)) - **Timing of fiscal years**: Fiscal years that span or begin after **December 31, 2023** fall under the new GMT rules. Plans to shift or align fiscal periods to optimize exposure should be evaluated.([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax.html?utm_source=openai)) - **Debt and intra-group financing**: Transactions between group members (e.g., interest, financing expenses) face stricter limitation (e.g., EIFEL rules) and potential disclosure under MDR. Avoid artificially inflating interest deductions or debt layering.([canada.ca](https://www.canada.ca/en/revenue-agency/corporate/about-canada-revenue-agency-cra/tax-canada-a-conceptual-study/tax-gap-brief-overview/federal-tax-gap-reduction-approach.html?utm_source=openai)) ## Practical Steps for Compliance - Assemble a **compliance team** to gather required data: naming, ownership, financials, jurisdictional tax rates for each entity in the group. Use this to compute GIRs and assess exposure to IIR or Domestic Top-Up Tax.([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/get-ready-file.html?utm_source=openai)) - Review existing structures that use offshore financing or third-party jurisdictions to see whether these are still cost-effective under GMT. Consider consolidating or changing ownership chains. Lots of once-popular tax planning strategies may now incur extra liability or risk. - Update corporate bylaws and intercompany agreements to align with thresholds and reporting obligations, especially to support data collection. Maintain proper record-keeping for at least **8 years**.([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/get-ready-file.html?utm_source=openai)) ## Example Structure Adjustment **Scenario**: Corp A (Canada parent) owns Entity B in offshore Country X (low tax), and uses divergent fiscal year ends. Under GMT, Country X’s low effective rate means Canada may impose IIR top-up tax. Moreover, GIR requires disclosure of Entity B’s tax numbers. **Adaptation**: - Adjust fiscal year ends so that reporting aligns, avoiding mismatches in income recognition. - Reallocate ownership or use intermediate entities in higher-tax jurisdictions to reduce IIR exposure. - Update internal accounting and disclosures for Entity B to feed into GIR requirements. ## Takeaway for Boardroom Strategy - GMT is here—if your revenue exceeds threshold—don’t wait for audits or penalties. - Use the new framework as a chance to clean up cross-border-edged operations and reduce complexity. - Seek tax-law experts familiar with Canada’s GMT regime and coordinate with counterparts abroad.
