Why it Matters
For Canadian parent companies and multinational groups operating in Mexico, tax compliance is more than an administrative obligation — it is a strategic priority. Mexico’s tax authorities (SAT) combine high statutory rates with one of the world’s most advanced digital enforcement systems, meaning that errors, omissions, or aggressive structures are quickly detected.
At Symbiosis, we work alongside our partner companies in a strategic relationship rather than a traditional service model. For us, effective tax planning is not only about minimizing liabilities, but about protecting cross-border investments, safeguarding reputation, and aligning governance practices between Canada and Mexico.
In today’s environment, robust compliance is the foundation for sustainable growth, investor confidence, and board-level decision-making.
Overview
Mexico maintains a 30% corporate income tax (CIT) rate and a 16% value added tax (VAT), with special incentives in certain border regions.
The SAT enforces compliance through:
- Electronic invoicing (CFDI 4.0) and mandatory add-ons (Payments 2.0, Carta Porte, etc.), enabling real-time oversight.
- Ultimate Beneficial Owner (UBO) disclosure requirements, with heavy penalties for non-compliance.
- General Anti-Avoidance Rule (GAAR, CFF art. 5-A) and reportable schemes regime, requiring business purpose and transparency.
- Implementation of the Multilateral Instrument (MLI, effective in Mexico since 2024), reshaping treaty use with the Principal Purpose Test (PPT) and expanded permanent establishment rules.
This context makes careful tax planning and corporate structuring not optional, but essential.
Common Challenges for Canadian Groups in Mexico
From our experience, boards and CFOs face recurring challenges when navigating Mexico’s tax landscape:
- Uncertainty when repatriating dividends or funding Mexican subsidiaries.
- Electronic audits and CFDI mismatches leading to immediate penalties.
- Misalignment between Canadian corporate governance expectations and Mexican compliance practices.
- Lack of clarity around tax incentives (e.g., Plan México, R&D credits).
These are the gaps where strategic tax planning creates real value.
Entity Selection and Operations
- Corporations (S.A. de C.V.): taxed at 30% on worldwide income. Dividends between resident entities are exempt, but distributions to individuals and non-residents face an additional 10% tax.
- Partnerships: taxed on an accrual basis, except for specific regimes.
- Branches (Permanent Establishments of foreign companies): taxed only on Mexican-source income, with a 10% withholding on remittances abroad.
Entity choice shapes not just tax cost, but flexibility in governance and cross-border planning.
Domestic and International Taxation
- Residents: taxed on worldwide income at 30%.
- Non-residents: taxed only on Mexican-source income.
- CFC/REFIPRE rules: low-tax jurisdiction income (<22.5%) is taxed immediately in Mexico.
- Tax treaties: more than 60, aligned with OECD standards and modified by the MLI.
- Foreign tax credits: limited to the Mexican liability on that income (per-country basis).
Incentives and Investments
Mexico fosters growth through:
- Plan México (Decree Jan. 21, 2025): immediate deduction of new fixed assets acquired Jan. 22, 2025 – Sept. 30, 2030, plus deductions for dual training and workforce development.
- Border region incentives: reduced CIT and VAT (8%) through Dec. 31, 2025, with registration requirements.
- R&D credit: 30% for approved projects.
Capitalisation and Financing
- Equity contributions: tax neutral if not distributed.
- Debt financing: deductible but limited by:
- Thin capitalisation: 3:1 debt-to-equity ratio.
- Earnings stripping: net interest capped at 30% of adjusted taxable income.
- Payments to low-tax jurisdictions: generally non-deductible, with possible 40% withholding.
Group Structures and Related-Party Transactions
- No full consolidation; instead, a tax integration regime allows 3-year deferral under conditions.
- Transfer pricing: OECD-aligned, with strict documentation rules.
- Symbiosis insight: transfer pricing in Mexico is not just technical; it often shapes board governance and audit committee oversight.
Third-Party and Cross-Border Transactions
- Sales of shares/assets: residents taxed at 30%; non-residents at 25% gross or 35% net (with requirements).
- Dividends: 10% withholding on post-2014 profits to individuals and non-residents.
- Interest, royalties, services: withholding applies, with reduced rates under treaties; up to 40% for tax havens.
- VAT: 16% standard, 0% exports and essentials, 8% in border regions (temporary incentive).
- Digital platforms: foreign providers must register and comply with VAT.
International Developments
- MLI (in force since 2024): treaty benefits now subject to PPT and broader PE rules.
- GAAR and reportable schemes: active compliance priorities.
- OECD Pillar Two (15% minimum tax): not yet adopted in Mexico, but on the legislative horizon.
