Tax planning for high-net-worth Canadians 2025: protect, grow, and transfer wealth the legal way

As personal net worth increases, so does exposure to complex taxation and heightened CRA review. High-income professionals, investors, and business owners must navigate layered taxation structures—from personal income and capital gains to estate and corporate taxes. Without proactive planning, millions earned over a lifetime can be lost in a single tax event.

The Income Tax Act (ITA) offers powerful, fully legal strategies that protect capital and accelerate wealth accumulation. In 2025, Mackisen’s CPA auditors and tax-law specialists design advanced structures—using holding companies, family trusts, rollover strategies, and capital gains exemptions—to secure clients’ fortunes while ensuring strict compliance with every CRA requirement.

The Legal Foundation for Wealth Protection

High-net-worth Canadians operate under the same ITA, but rely on advanced provisions and case law that enable tax-efficient structuring and inter-generational asset transfer.

Key income tax tools:

Section 85 – Tax-deferred rollovers when transferring assets into corporations
Section 110.6 – Lifetime Capital Gains Exemption (LCGE) — approx. $1M per person for qualified shares
Sections 70 and 73 – Deemed disposition and spousal rollover at death or transfer
Sections 104 and 107 – Trust income allocation and tax-free distributions
Section 125 – Small Business Deduction for low-rate active business income

Case authority: Shell Canada Ltd. v. Canada (1999 SCC 19) established the principle that taxpayers may structure affairs to minimize tax when compliant with statutory form — the foundation of legitimate tax planning in Canada.

Core Strategies for High-Net-Worth Clients

1. Holding Companies for Tax Deferral and Asset Protection
Holding companies (Holdcos) can receive inter-corporate dividends tax-free from operating companies (section 112(1)), allowing retained earnings to grow at low corporate rates (≈12–15%) instead of the 50%+ personal bracket. They also shield investment assets from operating liabilities, lawsuits, and creditor claims.

2. Family Trusts for Controlled Income Splitting and Succession
Trusts under sections 104 and 107 enable distribution of income to beneficiaries in lower tax brackets. Trust structures also avoid probate, provide confidentiality, and ensure wealth remains protected within the family — not exposed to divorce, claims, or poor financial decisions.

3. Multiplying the Lifetime Capital Gains Exemption
Under section 110.6, each adult beneficiary who owns qualified shares may claim approximately $1M in tax-free gains. Through a properly structured trust, families can multiply LCGE limits across multiple shareholders — eliminating millions in tax on exit.

4. Estate Freezes and Section 85 Rollover Planning
Estate freezes under section 86 lock today’s asset value so future appreciation shifts to heirs or a trust. Combined with section 85(1) rollovers, capital gains are deferred, preventing high estate tax triggered under section 70(5).

5. Corporate Investment Portfolios for Long-Term Compounding
Holdcos may invest retained earnings in real estate, private ventures, and market assets. While passive income over $50,000 impacts the Small-Business Deduction (section 125(5.1)), Mackisen structures layered entities to preserve low tax rates without jeopardizing corporate eligibility.

Advanced Planning Techniques

1. Philanthropic Foundations and Donation Credits
Donations under section 118.1 can eliminate up to 75% of taxable income annually. Private foundations create long-term family control over charitable commitments and reinforce your legacy.

2. Insurance-Based Estate Equalization
Corporate-owned life insurance increases the Capital Dividend Account under subsection 89(1), enabling tax-free distributions to heirs. It prevents forced liquidations and protects strategic assets (e.g., businesses and commercial real estate).

3. International and Residency Structuring
Sections 114 and 250 govern part-year and deemed residency rules. Strategic residency planning can reduce global tax exposure if executed before major liquidity events — while maintaining treaty compliance.

4. Post-Mortem Pipeline Planning to Avoid Double Taxation
Upon death, section 70(5) taxes corporate shares at fair market value — and dividends may be taxed again. Post-mortem pipeline planning converts dividends into capital gains under section 84(2) when commercially justified.

Case authority: Estate of Jean-Guy Giguère v. The Queen (2002 TCC 460) confirmed pipeline transactions remain valid when properly structured and documented.

Common CRA Triggers for High-Net-Worth Individuals

• Personal withdrawals without proper dividend/loan documentation (section 15(2))
• Unsubstantiated inter-company movement of funds
• Passive income exceeding $50,000 in CCPCs—reducing Small-Business Deduction
• Related-party loans at non-commercial interest rates (section 17)
• Trusts failing to file T3 returns or issue beneficiary slips
• Failure to comply with new beneficial ownership reporting requirements for corporations and trusts

Penalty alert: CRA can assess gross-negligence penalties up to 50% of understated tax (section 163(2)) plus high-interest charges under section 161.
