Post-Mortem Planning 164(6), Pipelines, the Bump & Where Life Insurance Fits

Why a private corporation can be taxed up to three times on the way to the estate

When a shareholder of a Canadian private corporation dies, the same pool of value can move through three separate tax events before the family sees it: a deemed disposition of the shares on the terminal return (Level 1), corporate tax on the sale of the underlying assets to wind the company up (Level 2), and personal tax on the distribution of the residual to the estate or beneficiaries (Level 3). Post-mortem planning — ss. 164(6), pipelines, the para. 88(1)(d) bump, and hybrid structures — exists to collapse two of those three layers. Permanent life insurance, used through the Capital Dividend Account, is what most often makes those tools work cleanly.

A $6M investment Holdco, Ontario, 50% inclusion rate

The example below is the canonical one used in the Manulife deck. Mr. A is 55, holds 100% of Holdco, ACB on the shares is nil, the marketable securities inside Holdco are worth $6M with an ACB of $3.5M. He passes away. There is no planning in place.

The 50% capital gains inclusion rate is used throughout this brief. The 2024 federal proposal to move the inclusion rate to 66.67% was cancelled in early 2025; planning is back to the 50% baseline. Top combined Ontario marginal rates: capital gains 26.77%, eligible dividends 39.34%, non-eligible dividends 47.74%, corporate (passive) 50.17%, RDTOH 30.67%.

Eliminate Level 1 by converting the gain into a dividend

The estate redeems the Holdco shares. The redemption is taxed as a deemed dividend under ss. 84(3), and the disposition proceeds are reduced by the dividend, leaving the estate with a capital loss. Subsection 164(6) lets that loss be carried back to the deceased’s terminal return and applied against the capital gain on the shares, eliminating Level 1.

• When it fits. Where the corporation has CDA, RDTOH, or both — so the redemption can be structured tax-efficiently using the capital dividend election under ss. 83(2) and the RDTOH refund.
• Timing. Must generally be carried out in the first year of a Graduated Rate Estate (GRE). A proposed extension to three years was announced but has not been enacted into law — do not rely on it.
• Stop-loss restrictions. Where CDA is used as part of the redemption, ss. 112(3.2) can grind the loss available for carry-back. The interaction with the “50% solution” (now the “33% solution” under the proposed amendments) is the central modelling exercise.
• What it leaves behind. The corporation is generally wound up after the redemption, so RDTOH and CDA balances are fully extracted.

Eliminate Level 3 by converting the share value into a tax-free promissory note

The estate incorporates Newco. It sells its $6M Holdco shares (which now have an ACB of $6M because of the deemed disposition on death) to Newco in exchange for a $6M promissory note. Holdco is then amalgamated with or wound up into Newco. Over the prescribed period, the note is repaid to the estate — tax-free, because it is a return of capital, not a dividend.

• When it fits. Where the capital gains rate at Level 1 is meaningfully lower than the non-eligible dividend rate at Level 3 — almost always true under the 50% inclusion regime.
• CRA conditions. The CRA’s administrative position (e.g. 2018-0748381C6) requires the corporation to remain active for at least one year before being amalgamated/wound up, and the note to be repaid in instalments over the following year. Distributions accelerated beyond that range can be re-characterised as a deemed dividend under ss. 84(2).
• GAAR exposure. The new general anti-avoidance rule (Bill C-59, in force June 2024) increases pipeline risk — the file should be documented with a clear non-tax purpose and, on larger files, an advance income tax ruling is increasingly common.
• What it leaves behind. RDTOH and CDA balances inside Holdco can be stranded unless extracted through a hybrid step.

Layer an ACB step-up on top of the pipeline

Same pipeline structure as Option B, except that on the amalgamation/windup of Holdco into Newco, the ACB of eligible non-depreciable capital property held inside Holdco is “bumped” up to the FMV at the date of death under para. 88(1)(d). The result: when Newco then sells those assets, the corporate-level gain at Level 2 is eliminated.

• When it fits. Where Holdco holds non-depreciable capital property — typically marketable securities, real estate, or shares of subsidiaries — that the family intends to sell or distribute after death.
• The 88(1)(d) restrictions. Bump denial rules apply to property acquired by Holdco from a non-arm’s-length person, depreciable property, and inventory. Cash, receivables, depreciable assets, and goodwill do not get the bump.
• What it leaves behind. The bump combined with the pipeline can collapse both Level 2 and Level 3 entirely on the eligible asset pool — only the Level 1 capital gain on the terminal return survives.

Use the redemption to extract CDA/RDTOH, then pipeline the rest

Hybrid planning combines a partial ss. 164(6) redemption with a pipeline on the balance. The redemption is sized to extract the CDA and RDTOH that would otherwise be stranded inside Holdco; the residual share value is pipelined out as a tax-free return of capital.

• When it fits. Where there are meaningful CDA and RDTOH balances at death — including, very often, where life insurance proceeds have just generated a large CDA credit.
• Why it matters here. A corporate-owned life insurance policy that pays a death benefit credits CDA in the amount of (DB − ACB). Hybrid planning is what lets the estate actually use that CDA on the way out.

Permanent life insurance inside the corporation is the post-mortem accelerant

Permanent life insurance does four things to the post-mortem plan that nothing else does as cleanly:

• It funds the tax. The death benefit is received by the corporation tax-free under ss. 148(1) on a life policy and pays the very tax bill the planning is trying to manage.
• It generates CDA. Death benefit minus ACB (which at advanced ages is typically a small fraction of the DB) credits the CDA under ss. 89(1). That CDA balance is what makes ss. 164(6) and hybrid planning produce the best outcomes.
• It adds executor flexibility. Because the proceeds arrive as a single tax-free payment, the executor can choose the post-mortem structure that fits the actual facts at the time of death, rather than having to pre-commit during the planning stage.
• It does not change the deceased’s lifestyle. Premium is paid by the corporation out of retained earnings the family was not going to consume.

The Manulife deck illustrates a joint-last-to-die PAR 90 policy ($200K/yr × 10 yrs, ~$4.2M DB plus deposit option) inside the same Holdco. Net result — with the policy and a hybrid post-mortem plan — was a meaningful increase in net value to the estate over the unplanned baseline, even after redirecting $2.0M of investable capital into premiums over the funding period.

Keep the capital deployed while the insurance compounds

Where the corporation does not want to redirect $200K/yr of investable capital into premiums, the Immediate Financing Arrangement (IFA) provides the financing layer. The corporation pays the premium; the same week, a Schedule I bank advances back up to 100% of the cash surrender value as a collateralised loan; the corporation redeploys those funds into the same portfolio it was running before. The policy keeps compounding on the full premium amount.

In the Manulife illustration, the IFA layered on top of the insured plan improves the post-mortem outcome further whenever the after-tax loan cost stays below the participating dividend scale — a spread that has held for most of the last 40 years. The full IFA mechanics are covered in the IFA — Corporate Borrowing brief.

How experienced advisors choose between 164(6), pipeline, bump, and hybrid

Overall. In the Manulife modelling, integrating permanent life insurance with a hybrid post-mortem plan generally produces a higher net estate value than the alternative-investment baseline. The underlying asset/insurance mix is the largest single driver of outcomes; the choice of post-mortem tool is the second.

Three things the file should have in place before death

• Will flexibility. The will should give the executor explicit authority to choose between ss. 164(6), pipeline, bump, and hybrid structures, including authority to incorporate Newco and execute the redemption or pipeline steps.
• Executor briefing. The executor should know that post-mortem planning needs to start within weeks of death — not months — because of the GRE one-year window.
• Insurance review. Permanent corporate-owned insurance, sized to the expected post-mortem tax bill and structured to credit the CDA at death, is the highest-leverage single planning step the file can take. It does not commit the executor to any one structure — it gives them the room to choose the best one.
