## What Is Canada’s Global Minimum Tax (Pillar Two)?
Canada’s Global Minimum Tax Act came into force in 2024 and applies to **qualifying multinational enterprise (MNE) groups** for fiscal years beginning on or after **December 31, 2023**. Its goal: ensure that MNEs pay an effective tax rate of at least **15%** in each jurisdiction where they operate—through an Income Inclusion Rule (IIR) and domestic minimum top-up tax.

## Who Is Affected?
- **Large corporations** with global consolidated revenue **exceeding €750 million**. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/whats-new-corporations.html?utm_source=openai))
- Entities in low-tax jurisdictions where the effective tax rate falls below 15%. Canada’s rules ensure top-up taxes so that the required rate is met. ([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/about.html?utm_source=openai))
- Smaller domestic firms are generally **not impacted**, unless they are part of a larger MNE group. ([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/about.html?utm_source=openai))
## Key Provisions & Effective Dates
- **Income Inclusion Rule (IIR)** & **Domestic Minimum Top-up Tax** are now law and apply for fiscal years starting **on or after December 31, 2023**. ([canada.ca](https://www.canada.ca/en/services/taxes/excise-taxes-duties-and-levies/global-minimum-tax/about.html?utm_source=openai))
- The **Undertaxed Profits Rule (UTPR)**—a backstop—was proposed to apply for fiscal years beginning **on or after December 31, 2024**. Legislative proposals for UTPR were released in 2024 and are still under consultation.

## Implications for Tax Planning & Compliance
MNEs must review their **business structures, foreign operations, and existing incentives** to ensure compliance. Some action steps include:
- **Assess effective tax rates** across jurisdictions to flag where top-ups may apply.
- **Align accounting practices**: consistent definitions for revenue, expenses, measures of tax base across jurisdictions.
- **Evaluate eligibility for incentives**: Some tax credits or deductions may reduce effective rates; ensure they’re structured to remain compliant.
- **Plan for reporting obligations**: new returns are required separately from the standard T2 business income tax return. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/whats-new-corporations.html?utm_source=openai))
## Example
Suppose a Canadian multinational company has a subsidiary in Country X that pays an effective tax rate of 10%. Under Pillar Two’s IIR, Canada would impose a **top-up tax** of **5%** on those profits so the combined effective rate equals 15%. If Country X already had a top-up rule, overlapping obligations may exist—planning must factor that in.
## Strategies to Stay Ahead
- **Monitor legislative developments**—UTPR rules and technical amendments (e.g. “de-consolidation”) are evolving.

- **Ensure proper documentation** to substantiate the effective tax rates used in foreign jurisdictions.
- **Engage tax advisers early**, especially in structuring foreign operations, investments, and partnerships.
- **Watch for audits and compliance actions**—CRA is expanding its risk-assessment tools. ([canada.ca](https://www.canada.ca/en/revenue-agency/corporate/about-canada-revenue-agency-cra/departmental-plan/2026-27-cra-departmental-plan.html?utm_source=openai))
