Your Portfolio Manager and Your Accountant Don't Talk, and It's Costing You Six Figures
A retired engineer in Oak Bay moves $900,000 from his employer pension into an RRSP and asks his wealth manager to replicate the dividend portfolio he's been running successfully in his corporation. The manager does. Over the next 18 months, the client watches $14,000 vanish to withholding tax on US dividends that would have been recoverable in a taxable account. His accountant sees it at filing time, a year after the damage is done, and mentions it in an email the wealth manager never reads. No one on the team is positioned to catch this before it happens.
It is structure, not negligence.
The Coordination Gap Is Built Into the Business Model
Portfolio managers earn fees as a percentage of assets under management. Their incentive is growth and retention. Tax efficiency matters to them when it affects the client relationship, but the metric they are judged on internally is gross return relative to a benchmark. Accountants, by contrast, are paid for compliance and historical reporting. They see what happened last year and file the forms. Neither party is naturally positioned to optimize the space between them, and neither is penalized when that space costs the client money.
A 2022 industry survey cited in Wealth Professional found that fewer than 20% of high net worth clients' advisors reported regular, proactive coordination across disciplines. The figure has likely improved since then, but the default remains siloed advice. Your mortgage broker does not call your portfolio manager before you refinance. The client is expected to coordinate across the accountant, the portfolio manager, and the mortgage broker, and most clients do not have the technical fluency to do that job.
Asset Location Eats Asset Allocation
Consider the specifics. A wealth manager might correctly identify a strong US equity position and place it in a TFSA for tax-free growth. What they miss: the 15% US withholding tax on dividends paid into a TFSA is non-recoverable, whereas the same dividend in a non-registered account would generate a foreign tax credit. Over a 10-year hold, that structural difference can cost $18,000 on a $100,000 position paying a 3% yield.
Or take the rebalancing problem. A portfolio manager sees that equities have appreciated and sells to restore the target allocation. The sale realizes a $60,000 capital gain. The client is above the $250,000 annual threshold, so the inclusion rate is 66.7%, not 50%. That gain lands in the same year the client sold a rental property and triggered another $180,000 gain. The combined inclusion pushes $160,000 of income into the top marginal bracket. The wealth manager saw a 7% equity position that needed trimming. The accountant, six months later, sees a $34,000 tax bill that could have been split across two years with a January sale instead of a December one.
No single advisor is seeing the whole board.
What Coordination Actually Requires
Integrated planning is conditional communication, not a meeting once a year where everyone nods. The portfolio manager should flag planned asset sales 90 days in advance so the accountant can model the tax impact against the year's other events. The accountant should inform the wealth manager when the client's income is spiking or when they are switching from employment to self-employment, which changes RRSP room and the value of income splitting. The mortgage broker should loop in both when a refinance creates new interest deductibility, because that changes the optimal debt structure for investments.
This requires either a lead strategist who coordinates the other advisors, or a client disciplined enough to force the connections themselves. For individuals with liquid assets under $2 million, hiring a family office or a dedicated integrator may cost more than the inefficiency. But for those above that threshold, the tax leakage from uncoordinated advice often exceeds the fee.
A business owner in Victoria sells their company in 2026. They have $1.2 million in gains eligible for the lifetime capital gains exemption. Their wealth manager, unaware of the sale, rebalances the non-registered portfolio in the same quarter and realizes $70,000 in gains. The rebalance is sound in isolation. In context, it wastes part of the exemption's shelter and triggers $18,000 in tax that could have been deferred or avoided. The accountant sees it after the fact. The client pays.
Fragmented advice is cheaper up front. What it costs is visibility, and visibility in tax planning is the difference between optimizing and reacting.
