Subsection 70(5) of the Income Tax Act deems your private corporation shares sold at fair market value the moment you die. The capital gains tax is calculated on your final return. Then your estate gets taxed again when it extracts the value from the corporation. Without planning, the combined rate can exceed 75%. With the right strategy, it drops to 26.75%.
Capital gains tax on a $3M BC corporation at death
(FMV $3M – ACB $1,000 = $2,999,000 gain × 26.75%)
The second layer of tax most owners don't know about
(Deemed dividend on share redemption at 48.89%)
With a pipeline strategy
Tax saved: $1,466,211
When you die owning shares of a private corporation, two tax events happen.
CRA deems you to have sold your shares at fair market value. Capital gains tax is calculated on your terminal return. On a $3M BC corporation, that is approximately $802,233.
Your estate now holds shares with a stepped-up cost base equal to the FMV at death. But the corporation still holds the same retained earnings. When your estate redeems or winds up those shares, the difference between the redemption price and the paid-up capital is treated as a deemed dividend — not a capital gain. On the same $3M corporation, that deemed dividend tax is approximately $1,466,211.
Combined: $2,268,444 in total tax on a $3,000,000 corporation. Effective rate: 75.6%.
This is not a theoretical scenario. It is the default outcome under the Income Tax Act for every incorporated business owner who dies without post-mortem planning.
Same corporation. Same value. Different outcome.

64.6% reduction in estate tax liability
CRA confirmed at the 2024 STEP Roundtable that well-structured pipelines remain valid under the amended GAAR.
Eliminates the deemed dividend entirely. Your estate creates a new corporation, sells the shares to it, and winds down the original through inter-corporate dividends — tax-free under Section 112.
Tax saved: $1,466,211. Effective rate drops to 26.75%.
The estate redeems shares, triggering a capital loss carried back to offset the original capital gain. Eliminates the first layer but converts extraction to dividend treatment. Carryback window extended to 3 years for deaths after August 12, 2024.
Effective rate: approximately 48.89% in BC.
Locks your corporation's current value on preferred shares under Section 86 or 85(1). Future growth passes to the next generation. Makes the tax bill predictable and insurable. Corporate-owned life insurance funds the exact amount needed — death benefit credits the CDA, paid out as tax-free capital dividend.
Predictable. Insurable. Funded.
The $1,250,000 Lifetime Capital Gains Exemption saves ~$334,000 per person at BC rates. Through a family trust, four beneficiaries can each claim their own LCGE, sheltering up to $5,000,000 in gains. Requires shares to qualify as QSBC (90% active business assets test).
Potential savings: $1,337,500 with four beneficiaries.
Want to know which strategy applies to your corporation?
Section 70(5) does not distinguish by industry, company size, or how long you have owned the business. It applies equally to:
Construction companies
Trades contractors (plumbing, electrical, HVAC, excavation)
Professional corporations (doctors, dentists, lawyers, engineers)
Real estate development and management
Manufacturing and distribution
Technology companies
Holding companies (Holdco/Opco)
Any incorporated business in BC or Alberta
If you hold shares in a Canadian private corporation and you plan to die someday, subsection 70(5) will apply to those shares.
| Item | BC | Alberta |
|---|---|---|
| Probate on a $2M estate | $27,650 | $525 |
| Top capital gains rate | 26.75% | 24.00% |
| Top marginal rate (ordinary income) | 53.50% | 48.00% |
| Non-eligible dividend rate (top) | 48.89% | 44.00% |
| Small business deduction threshold | $500K | $500K |
| Lifetime Capital Gains Exemption (2025) | $1.25M | $1.25M |
BC:
Alberta:
That's a 79x difference. And probate is the smallest cost in your corporate estate.
Bottom line: On a $3M corporate estate, BC owners can pay $27,000+ more in probate alone compared to Alberta — plus higher capital gains and dividend tax rates at every level.
Your corporation grows every year. Retained earnings compound. Equipment appreciates or is replaced with higher-value assets. Every year you wait, the deemed disposition tax bill at death gets larger. A corporation growing at $200K per year adds approximately $53,500 in additional estate tax per year at BC rates.
Meanwhile, the cost of life insurance increases every year you age. A $1M whole life policy at age 50 costs roughly 40% less than the same policy at age 60. And your insurability is not guaranteed — a single health event could make coverage unaffordable or unavailable entirely.
An estate freeze done today locks your tax bill at today's value. An estate freeze done five years from now locks it at a $1 million higher value. The math only moves in one direction.
The spousal rollover under Section 70(6) defers the deemed disposition. Your spouse inherits the shares at your original cost base. No tax on the first death. But the corporation keeps growing. When your spouse dies, the full gain crystallizes — on a larger corporation with no further deferral available.
A $3M corporation growing to $4M over 5 years adds $2.28 million to the eventual tax bill versus planning at the first death.
The combined exposure on a corporation plus multiple properties is where the biggest numbers are. A BC owner with a $3M corporation and one rental property faces over $560,500 in combined estate tax and probate. That's corporate deemed disposition plus property capital gains plus CCA recapture plus BC probate — all on one terminal return.
See the property estate risk mathThe deemed disposition applies at death, but selling during your lifetime gives you control over timing and tax planning. You can structure the sale to use your Lifetime Capital Gains Exemption, spread capital gains across tax years, or implement a pipeline strategy to extract retained earnings at the capital gains rate instead of the deemed dividend rate. Selling before death is often the best outcome — it just requires intentional planning.
Yes. Section 70(5) applies equally to professional corporations including doctors, dentists, lawyers, engineers, and accountants. Professional corporations often accumulate significant retained earnings and hold expensive assets like medical equipment, client lists, or commercial real estate. The deemed disposition rules are identical — your shares are deemed sold at fair market value at death, triggering the same two-event tax problem.
The spousal rollover defers the tax but does not eliminate it. When you die, your corporate shares can transfer to your spouse at your original cost base — no immediate tax. But on the second death, when no further rollover is available, the full tax bill crystallizes. The problem is usually larger at that point because the corporation has continued to grow, and your spouse may be in a higher tax bracket due to RRIF income, CPP, and other sources. Deferral is not a strategy — it is just delayed planning.
CRA uses fair market value at death, which includes retained earnings, goodwill, equipment, inventory, and any real estate held inside the corporation. Most owners significantly underestimate this number. A construction company with $800K in retained earnings, $200K in equipment, and $150K in receivables might be "worth" $1.2M to $1.5M for estate tax purposes — even if the owner thinks of it as a modest operation.
Your accountant handles your annual tax filings. Estate risk planning requires coordination between your accountant, your lawyer, and an insurance professional. Most accountants will confirm: quantifying the Section 70(5) exposure and funding the solution is not something they do in your annual review. We don't replace your accountant — we work alongside them to calculate the number they don't have time to show you.
The cost of life insurance increases every year you wait. More importantly, your insurability is not guaranteed. A health event at 55 could make coverage unaffordable or unavailable. And every year your corporation grows, the tax bill grows with it. An estate freeze done today locks the liability at today's value. An estate freeze done in five years locks it at a higher value. The math only moves in one direction.
