Preparing for the 2026 Tax Horizon: Projected Changes & Corporate Strategy

As we approach 2026, Canadian business owners and high-net-worth individuals must navigate a tax landscape that is shifting under the weight of inflation and new federal policies. While the Canada Revenue Agency (CRA) typically finalizes specific indexation factors late in the preceding year, the trajectory for 2026 is clear: higher brackets, but also tighter rules on wealth accumulation.

1. Inflationary Bracket Creep: The Good News

With inflation remaining a central economic theme, the federal tax brackets are expected to see significant indexation adjustments heading into 2026. This "bracket creep" is designed to prevent taxpayers from moving into higher marginal rates simply due to cost-of-living salary increases.

For corporations, this emphasizes the importance of salary vs. dividend mix. As personal brackets expand, there may be new room to extract slightly more salary at lower effective rates, optimizing RRSP contribution room which is also indexed.

2. The Capital Gains inclusion Rate: The New Reality

The most profound shift affecting corporate portfolios is the increase in the Capital Gains Inclusion Rate (from 50% to 66.67% for corporations and trusts, and for individuals on gains over $250,000). By 2026, the full impact of this policy will be felt in annual filings.

Strategic Pivot: This change effectively increases the tax cost of selling corporate investments (stocks, real estate) by nearly 33%. Strategies like the Capital Dividend Account (CDA) become even more critical, as maximizing the tax-free portion of capital flows is now the only way to offset this erosion.

3. Alternative Minimum Tax (AMT) Reforms

Refinements to the AMT regime will fully mature by the 2026 tax year. These changes specifically target high-income earners who rely heavily on tax deductions and credits. Business owners utilizing aggressive deduction strategies need to review their personal exposure, as the AMT exemption amount has increased, but the breadth of disallowed deductions has widened.

Looking Ahead

Success in 2026 will not come from passive holding. It requires active restructuring—leveraging Corporate Estate Freezes and Insurance-based asset classes (which remain largely exempt from the inclusion rate hike) to protect long-term equity.
