The short answer
Generally no. A corporation cannot deduct premiums on life insurance it owns, even when the policy protects the business. The main exception is the collateral insurance deduction under paragraph 20(1)(e.2): when a restricted financial institution requires the policy as loan collateral, a portion capped by the net cost of pure insurance may be deductible.
corporate-life-insuranceIt is usually the first question an incorporated physician or dentist asks when corporate-owned life insurance comes up: can the corporation deduct the premiums? The instinct is reasonable. The corporation deducts rent, staff, equipment, and insurance on the building, so insurance on the person who generates all the revenue feels like it should follow. It does not. This post explains why the deduction is denied, the one exception and its exact conditions, and why the strategy's real tax case never depended on deductibility in the first place.
The direct answer: a corporation cannot deduct premiums on a life insurance policy it owns, whether the policy is term or permanent, and whether it protects a key person, secures a buy-sell agreement, or funds an estate plan.
The Income Tax Act gets there through its general limitations in section 18. A deductible expense must be laid out to earn income from the business or property, and a premium that buys a death benefit payable to the corporation is not that: it buys a capital receipt that arrives tax-free. The Act does not tax the death benefit as income, and the price of that treatment is that the cost of buying it is not deductible either. The symmetry is deliberate. Tax-free proceeds in, after-tax premiums out.
This catches structures people assume are different. Key person insurance: not deductible. A policy backing a shareholder agreement's buy-out obligation: not deductible. A policy the corporation owns to fund the tax bill on death: not deductible. The purpose being commercially sensible does not change the character of what the premium buys.
The direct answer: paragraph 20(1)(e.2) allows a deduction for a portion of premiums, but only when a restricted financial institution requires the policy as collateral for a borrowing whose interest is itself deductible, and only up to the net cost of pure insurance prorated to the loan balance.
Every condition matters, and they are conjunctive: all of them must hold at once.
First, the policy must be assigned to a restricted financial institution, a defined term that covers banks, trust companies, credit unions, and similar regulated lenders. An assignment to a private lender, a family trust, or another corporation in the group does not qualify.
Second, the lender must require the assignment as a condition of the borrowing. A voluntary pledge of a policy the bank did not ask for fails the test. In practice, lenders that want the security document it in the credit agreement, which is exactly the paper CRA looks for.
Third, the interest on the borrowing must be deductible, which means the borrowed money is used to earn income from a business or property. A loan that funds the practice, an investment portfolio, or an income-producing property can qualify. A loan that funds personal spending cannot.
Fourth, even when everything above holds, the deduction is capped at the lesser of the premiums payable and the net cost of pure insurance for the year, and only the portion that relates to the amount owing under the loan counts. If the policy's death benefit is much larger than the loan balance, only the slice securing the loan generates a deduction.
The direct answer: the net cost of pure insurance is the actuarial cost of the year's mortality coverage, defined in Regulation 308, and on a heavily funded permanent policy in its funding years it is typically well below the premium, with the exact figure shown year by year on the carrier illustration.
A permanent policy's premium has two jobs: paying for this year's insurance coverage and funding the policy's long-term values. The NCPI isolates the first job. It is the prescribed mortality rate for the insured's age applied to the policy's net amount at risk, and how it compares to the premium is policy-specific: the illustration's NCPI column, not a rule of thumb, is what any deduction is capped at.
Two properties of the NCPI are worth knowing. Its path over time is driven by two moving parts pulling in opposite directions, a mortality rate that rises with age and a net amount at risk that shrinks as the policy's values grow toward the death benefit, so it does not move in one direction for every policy or every year. And it is the same quantity that drives the policy's adjusted cost basis downward under section 148, which is why the ACB of many permanent policies falls to or near zero at older ages, the mechanic behind the capital dividend account credit covered in the capital dividend account post.
The practical conclusion is unglamorous: even in a textbook collateral arrangement, the deduction is a modest annual amount tied to a mortality cost, not a write-off of the premium. Anyone modelling a strategy where the premium deduction carries the economics has modelled it wrong.
The direct answer: mostly in collateral lending arrangements, where a corporation borrows against a policy's values from a bank that requires the policy as security.
The pattern appears in practice financing, where a lender takes a collateral assignment of an existing policy alongside other security. It is also the backbone of more deliberate structures in which a corporation funds a permanent policy and then borrows against it to reinvest in the business or portfolio, keeping capital working while the policy grows. Those arrangements have their own risks and their own suitability tests, and they deserve their own treatment; the point here is narrower. When a qualifying borrowing exists, the 20(1)(e.2) deduction and the interest deduction are real, and they are the only deductions in the neighbourhood of a corporate-owned policy.
What the exception is not is a planning goal in itself. Buying insurance to manufacture a deduction capped at the NCPI is backwards; the deduction is a by-product of a lending decision that has to make sense on its own.
The direct answer: corporate-owned life insurance earns its place through cheaper funding dollars, tax-exempt growth, and the capital dividend account at death, all of which survive the premiums being non-deductible.
Compare the funding dollars. A premium paid personally comes out of income taxed at personal rates, up to 53.53 percent at the Ontario top bracket in 2026. The same premium paid by a CCPC comes out of income taxed at corporate rates first: 11.2 percent combined on active income within the small business limit, a rate fully in place only for taxation years falling entirely after June 30, 2026 (straddling years are prorated), and only while the corporation still has small business deduction room. Non-deductible with cheap dollars beats non-deductible with expensive dollars, and both are non-deductible.
Then the growth: an exempt policy's internal growth is not taxed annually, unlike the corporation's portfolio income, which faces the passive investment rates and feeds the small business deduction grind. And at death, the benefit minus the policy's adjusted cost basis credits the capital dividend account, the mechanism that lets corporate money exit tax-free. The full architecture, ownership structure, beneficiary designation, the ACB curve, and the estate comparison, is in the corporately-owned life insurance guide.
For an incorporated professional weighing all of this against their own numbers, that structural conversation is what financial planning for physicians describes.
Premiums on corporate-owned life insurance are not deductible, and no restructuring of purpose or beneficiary changes that. The single exception is the collateral insurance deduction, with four conditions that must all hold and a cap at the net cost of pure insurance that keeps it small. If someone is selling you a corporate policy on the strength of a premium deduction, the pitch is wrong. If the policy makes sense, it makes sense for the three reasons that were always the case: cheaper corporate dollars funding it, exempt growth inside it, and the capital dividend account waiting at the end.
Almost never. Premiums on a policy the corporation owns are not an outlay incurred to earn income under the Income Tax Act's general deduction rules, so they are paid with after-tax corporate dollars. The narrow exception is the collateral insurance deduction in paragraph 20(1)(e.2), which applies only when a restricted financial institution requires the policy as security for a loan.
All of them must hold: the policy is assigned to a restricted financial institution (a bank, trust company, or similar lender) as collateral for a borrowing; the lender requires the assignment; the interest on the borrowing is itself deductible, meaning the borrowed money is used to earn income; and the deduction is limited to the lesser of the premiums payable and the net cost of pure insurance, prorated to the amount owing during the year.
Because the case was never about deductibility. Corporate dollars are taxed at lower rates than personal dollars before they pay the premium, growth inside an exempt policy is not taxed annually the way portfolio income is, and at death the benefit less the policy's adjusted cost basis credits the capital dividend account for tax-free extraction. Those three mechanics do the work.
Rarely. The cap is the net cost of pure insurance, an actuarial mortality cost defined in Regulation 308 that is typically well below the premium on a permanent policy in its funding years; the year-by-year figure is on the carrier illustration, and only the portion tied to the loan balance counts. Treat any deduction as a modest by-product of a lending arrangement, not a reason to buy insurance.
