## Bill C-15: What Changed in Transfer Pricing
Receving **Royal Assent on March 26, 2026**, Bill C-15 enacts several major tax measures including **new transfer-pricing adjustment rules** and **documentation requirements** effective for tax years beginning **after November 4, 2025**.([kpmg.com](https://kpmg.com/us/en/taxnewsflash/news/2026/04/tnf-canada-2025-budget-tax-measures-including-new-transfer-pricing-rules-and-repeal-of-dst-enacted.html?utm_source=openai))
Under the new rules, Canadian taxpayers must analyze not just contracts but also **other economically relevant characteristics** when evaluating cross-border, non-arm’s-length transactions.([kpmg.com](https://kpmg.com/us/en/taxnewsflash/news/2026/04/tnf-canada-2025-budget-tax-measures-including-new-transfer-pricing-rules-and-repeal-of-dst-enacted.html?utm_source=openai))
## Implications for Private Multinational Enterprises (PMEs)
Here “Private Multinational Enterprises” refers to Canadian-controlled firms with foreign affiliates, or otherwise conducting international trade or service relationships with related parties. Key impacts:
- Greater substantiation required in transfer pricing studies—the “arm’s-length standard” now extends beyond just written contract terms to include business practices, risk allocations, and other economic factors.
- Documentation requirements will likely increase in breadth—companies must prepare disclosures to demonstrate compliance.
- Risk of adjustment if structures or operational realities differ from the written contract or standard documentation.
## Example: Mid-Sized Canadian Manufacturer
A manufacturer in Ontario sells components to its affiliate in Mexico. Pre-Bill C-15, their written agreement sets a margin. Post-Bill C-15, CRA will examine:
- Whether manufacturing risk, IP ownership, supply chain functions are aligned with what's in documents.
- If, e.g., the Canadian side performs more of the value-added work or bears risks, but contracts don’t reflect this, CRA may require adjustments.
## Action Plan for PMEs
1. **Review existing TP arrangements** to ensure they reflect actual operations: responsibility, IP ownership, and risk exposure must align with contract and conduct.
2. **Update transfer pricing policies and manuals**, ensuring that economically relevant characteristics are well documented.
3. **Engage independent TP studies or advisors** to review comparables and properly justify margins and risk.
4. **Implement internal audits** to catch misalignments proactively.
5. **Budget for additional compliance costs**: These rules may increase documentation, legal, or advisory expenses.
## Broader Tax Planning Considerations
- Consider restructuring high-risk intercompany transactions well before the fiscal year after November 4, 2025.
- Align supply chain, production, or IP holding entities to reduce taxable transfer pricing adjustments.
- Evaluate whether existing oversights in contracts might expose the company to penalties or re-assessment.
**Conclusion**: Bill C-15’s expanded transfer pricing rules bring sharper scrutiny over cross-border dealings. Proactive alignment of operations, contracts, and documentation by PMEs will help avoid costly adjustments.
