Financial Planning for High-Income Earners in Ontario

High income creates high opportunity — and high complexity. In Ontario, individuals earning above roughly $150,000 face marginal tax rates that make strategic financial planning not just helpful but essential. Without deliberate structure, a significant portion of a high earner's income flows to the government unnecessarily — not through any wrongdoing, but simply through inaction.

Marc Pineault is a financial planner with The Co-operators who works with high-income professionals, incorporated business owners, and executives across Ontario. This article outlines the key areas where financial planning adds measurable value for those with above-average incomes.

The Tax Reality for High Earners in Ontario

Ontario has some of the highest combined marginal tax rates in North America. An individual earning over $246,752 (the 2025 federal top bracket) pays a combined federal-provincial rate exceeding 53% on the marginal dollar. Even at $100,000 to $150,000, effective marginal rates in Ontario range from 43% to 48%.

This means that tax planning is not a peripheral concern — it's central to how much of your income you actually keep. Every major financial decision a high earner makes has a tax dimension: how you're compensated, where savings are held, when income is recognized, and how assets are eventually transferred.

Corporate Structures and Incorporation

Many high-income professionals — physicians, dentists, lawyers, consultants, engineers — operate through professional or personal corporations. For high earners outside incorporated structures who have the option to incorporate, this is often the most significant financial planning conversation available.

Tax deferral through the corporation — Income retained inside a corporation is taxed at the small business rate (currently around 12.2% in Ontario), rather than at personal marginal rates of 43-53%. That differential allows earnings to compound inside the corporation before being extracted as personal income in a lower-tax year (often retirement).

Income splitting — Family members who are shareholders and active in the business may be able to receive dividends, distributing income across lower-bracket family members. The rules around income splitting have tightened in recent years (TOSI rules), and navigating them correctly requires coordination between your financial planner and accountant.

Holding company structures — For high earners with significant retained earnings, a holding company can provide additional planning flexibility and asset protection.

RRSP Strategy at High Income

The RRSP is most powerful as a tax-reduction tool when contributions are made in high-income years and withdrawals occur in lower-income years. For high earners, this is a genuine arbitrage opportunity.

At $200,000 of income, contributing to an RRSP produces a tax refund of approximately $530 for every $1,000 contributed (at Ontario's 53% marginal rate). If that same money is withdrawn in retirement at an effective tax rate of 25-30%, the tax savings are substantial — on top of decades of tax-deferred growth.

The challenge for many high earners: they've maximized RRSP contributions and still have significant capital to deploy. That's where TFSA, corporate accounts, and other strategies become relevant.

TFSA: Underutilized by High Earners

The TFSA is arguably more valuable for high-income earners than for anyone else, precisely because of the high marginal rates at play. Tax-free compounding inside a TFSA, followed by tax-free withdrawals in retirement, produces a better after-tax outcome than equivalent growth in a non-registered account — which faces annual tax on dividends and capital gains.

Many high earners underfund their TFSA in favour of registered savings alone. A financial planner ensures TFSA room is being used strategically.

Investment Strategy and After-Tax Returns

At high income, the after-tax return on investments in non-registered accounts is significantly affected by how those investments are structured. Canadian dividends receive preferential tax treatment. Capital gains are taxed at a lower effective rate than interest income. These distinctions compound meaningfully over time.

A financial planner coordinates investment strategy with your tax situation — not just looking at pre-tax returns, but at what you actually keep.

Insurance as a Wealth Management Tool

High earners sometimes have insurance needs that go beyond basic protection into estate planning and tax-efficient wealth transfer:

Permanent life insurance — In certain situations, permanent life insurance (whole life or universal life) can serve as a tax-sheltered growth vehicle and an efficient way to transfer wealth to the next generation, particularly for high earners who have maximized other tax-sheltered accounts.

Disability income protection — Group coverage through an employer or association often has caps that leave high earners significantly underinsured relative to their actual income. Reviewing actual coverage levels against actual income is a standard step in financial planning for this group.

Estate Planning for High Net Worth

As wealth accumulates, the estate planning questions become more complex. Probate fees in Ontario are calculated as a percentage of estate value. The deemed disposition rules at death can trigger significant capital gains. The right estate structure — in coordination with your lawyer — can meaningfully reduce the tax and administrative burden on your estate.

A financial planner doesn't replace your estate lawyer or accountant — but they bring the financial planning perspective to make sure all three disciplines are working together.
