For many affluent Canadians, investment performance isn’t the main bottleneck—tax drag is. When portfolios span corporations, trusts, registered accounts, and multiple currencies, every decision has an after-tax ripple. The goal of ultra high net worth wealth management isn’t simply to “beat the market”; it’s to design a coordinated, tax-aware system that keeps more of what you already earn. Here’s a plain-English playbook to do just that.

Two people reviewing financial documents with calculator and pen.

Start with an after-tax policy (not just an IPS)

Most investors have an Investment Policy Statement. Fewer have an after-tax policy that sets rules for where assets live, how gains are realized, and how cash moves through the structure. Write a one-pager that covers:

  • Goals and horizon: spending, philanthropy, generational transfers.
  • Account map: RRSP/RRIF, TFSA, non-registered, corporations/holdcos, trusts, pensions.
  • Constraints: liquidity needs, currency, concentration (e.g., private business, real estate).
  • Realization rules: when to crystallize gains/losses, how to use losses, and guardrails for turnover.

This document becomes the north star for every portfolio and tax decision.

Pull the four big levers

1) Asset location: put the right assets in the right “containers”

Different accounts are taxed differently. A tax-aware design will locate income types where they’re treated best, for example:

  • Use registered accounts for high-yield or actively traded strategies that would otherwise distribute fully taxable income.
  • Reserve TFSAs for the highest expected after-tax growth, since gains are tax-free.
  • In non-registered or corporate accounts, prefer vehicles that emphasize deferral and capital-gains-weighted returns over frequent, fully taxable distributions.
  • Where corporations are involved, align the investment mix with corporate tax rules and cash-flow needs from the operating company.

The principle is simple: defer, downgrade, or avoid tax where you can—without distorting risk.

2) Asset selection: minimize involuntary payouts

Two funds with identical pre-tax returns can produce very different after-tax outcomes. Tilt toward:

  • Low turnover mandates to reduce accidental capital gains.
  • Structures that limit surprise distributions.
  • A thoughtful dividend policy: more isn’t always better if it increases current tax when you don’t need the cash.

Ask for a tax-cost ratio (or equivalent) alongside performance so you can see the silent drag you’re paying.

3) Cash-flow and sequencing: plan withdrawals like a flight path

Decumulation is where fortunes leak. Build a multi-year withdrawal plan that coordinates:

  • RRSP/RRIF, TFSA, non-registered, and corporate cash,
  • pension options and timing,
  • gain realization vs. deferral, and
  • foreign-withholding nuances where relevant.

Sequencing should aim to smooth income over time, avoid unnecessary surtaxes/benefit clawbacks, and preserve tax-advantaged room (e.g., keep TFSA compounding).

4) Corporate and trust integration: align the scaffolding

For owner-managers and families using holding companies or trusts, ensure the legal scaffolding supports the after-tax plan. Coordinate with your accountant and legal counsel on topics like surplus extraction, inter-generational transfers, and documentation. The portfolio should follow the structure—not fight it.

Philanthropy as part of the engine

Charitable giving is values-driven—and it’s also a powerful tax lever when done right. Consider:

  • In-kind gifts of appreciated securities to eliminate tax on the gain while receiving a receipt at fair market value.
  • Using a donor-advised fund to “pre-fund” future gifts in high-income years, then grant steadily.
  • Designing a family giving policy so philanthropy remains consistent through market cycles and leadership changes.

Philanthropy can convert inevitable tax into enduring impact.

Measure what matters

Judge success by after-tax results and predictability, not just headline returns. Ask your team to report:

  • After-tax performance vs. a sensible benchmark,
  • Tax-cost ratio and realized gains each year,
  • Forward tax exposure (unrealized gains, embedded distributions), and
  • Progress on funding goals (spending, liquidity, giving, legacy).

Transparency turns tax from an annual surprise into a managed variable.

Common mistakes to avoid

  • Chasing pre-tax yield that inflates current tax without increasing real wealth.
  • Over-trading in taxable accounts, creating a trail of distributions.
  • Ignoring adjusted cost base (ACB) tracking and superficial loss rules.
  • One-account thinking—optimizing inside each account while sub-optimizing the whole.

Where the right advisor fits

Great ultra high net worth wealth management coordinates portfolio design, tax planning, and structure under one roof—and explains it all in plain language. The team you want doesn’t just pick investments; they write (and maintain) your after-tax policy, model cash-flow and sequencing years ahead, and collaborate seamlessly with your accountant and lawyer.

Bottom line: Taxes are a controllable headwind. With a concise policy, disciplined asset location, smart selection, and intentional sequencing, you can meaningfully lift after-tax returns—without swinging for the fences. Start by putting your after-tax policy on paper. The compounding from fewer leaks begins immediately.
