Life insurance premiums are generally not deductible, personally or corporately, apart from the narrow collateral-loan exception under paragraph 20(1)(e.2); both the rule and the exception are covered in the deductibility post. What is not settled for most incorporated professionals is the question that actually moves money: which pocket should pay them? Both pockets hold after-tax dollars, but they are not taxed alike, and for a policy that will run for decades the difference compounds into one of the larger planning decisions an owner makes without noticing. This post runs the arithmetic at 2026 Ontario rates and covers the traps on the way.
The two pockets, priced
The direct answer: at top rates, a dollar in your personal account cost roughly two dollars of corporate earnings to put there, while a dollar in the corporation's account cost about $1.13, and premiums care only about which account they leave.
Take a $30,000 annual premium on a corporately relevant permanent policy. To pay it personally, the money must first get to you. Via dividends at the top Ontario non-eligible rate of 47.74 percent, you need a $57,405 dividend to net $30,000, and at Ontario's 11.2 percent small business rate the corporation needs about $64,645 of active income to fund that dividend. The salary route lands in the same neighbourhood: at the 53.53 percent top bracket, $64,558 of salary nets $30,000. Call it $64,600 of corporate earnings either way.
Now have the corporation pay the same premium. At the 11.2 percent combined small business rate, $33,784 of active income leaves $30,000 after corporate tax. The identical premium consumes roughly half the pre-tax earnings, a gap of about $30,800 every year the policy is funded. Over a twenty-year funding schedule that is on the order of $600,000 of practice earnings that one pocket burns and the other does not, before any investment on the difference.
The usual qualifiers apply to the 11.2 percent figure: it holds for taxation years falling entirely after June 30, 2026, straddling years are prorated, and the corporation must still have small business deduction room. A corporation paying the general rate funds premiums with $40,816 per $30,000, and one whose income the passive income grind has displaced pays from 17.2 percent dollars, $36,232. Every corporate variant beats the personal pocket by a wide margin.
Below the top bracket, the gap shrinks, and can nearly close
The direct answer: the two-to-one gap assumes the extraction lands entirely in the top bracket; at lower incomes the progressive brackets and the dividend tax credit shrink it, to a few thousand dollars for an owner with no other income.
The figures above are top-bracket arithmetic and should be read that way: they assume the whole extraction stacks above roughly $258,000 of other income, and the salary framing ignores payroll costs. Run the same $30,000 premium through the progressive 2026 Ontario brackets instead, with the salary vs. dividends optimizer engine, and the picture is graded. An owner with no other personal income nets $30,000 from about a $32,600 non-eligible dividend, which costs roughly $36,800 of corporate income against the $33,800 the corporation pays directly: a gap of only about $3,000, because dividend rates in the low brackets are small. An owner who already has $150,000 of taxable income needs about $55,900 of corporate income. At the top bracket it is the $64,600 above. All three figures leave out the Ontario Health Premium and any payroll costs, which push the personal route somewhat higher.
The honest pattern: the corporate pocket's advantage is a function of the owner's marginal position, not a law of nature. For an incorporated professional already extracting a full income, the common case, the gap is large and repeats every premium year. For an owner with unused low brackets, extraction is cheap and the funding gap genuinely narrows to noise; the decision then rests on the ownership questions below, not on funding arithmetic.
One planning consequence follows: if a policy is going to be owned corporately anyway, funding it corporately is not a separate decision, it is the same decision. The cases that deserve real thought are the ones where ownership itself is in question, which is where this post ends up below.
Why cheap dollars are not a free lunch, and why it mostly does not matter
The direct answer: corporate dollars are cheap because personal tax has been deferred, not cancelled, but for a policy the corporation owns to its own benefit, the deferral largely converts to a permanent advantage at death.
The honest objection: money kept in the corporation has not finished being taxed. Ordinary corporate surplus eventually exits as taxable dividends, so part of the funding advantage is timing. For most corporate wealth that is exactly the right way to think about it.
The insurance case has a different ending. The corporation is not accumulating a portfolio it must someday distribute; it is paying for a death benefit it will itself receive tax-free. At death, the benefit minus the policy's adjusted cost basis credits the capital dividend account, and that amount exits to the estate with zero personal tax by election. The mechanics are in the capital dividend account post. Funding from cheap dollars and exiting through the CDA is the pairing that makes corporate ownership the default structure for permanent coverage on an incorporated professional, and the full architecture is the corporately-owned life insurance guide.
The trap: mixing the pockets
The direct answer: the corporation paying premiums on a policy you own personally is generally a taxable shareholder benefit, the most expensive structure available.
Subsection 15(1) is the provision that polices the boundary. When a corporation confers a benefit on a shareholder, the benefit's value is taxed in the shareholder's hands, with no deduction to the corporation. A corporation paying the premiums on the shareholder's personally owned policy is the textbook pattern: you pay personal tax on the premium amounts without ever receiving cash, and the corporation's payment bought an asset it does not own. The same analysis threatens mismatched structures, such as a corporately owned policy whose death benefit is directed personally without the compensation paperwork to support it. The details are fact-specific, which is itself the warning: this is not a corner to design casually. The clean structure keeps owner, payer, and beneficiary aligned, one corporation wearing all three hats, and it is cheap to get right at issue and expensive to repair later.
What personal ownership is still for
The direct answer: coverage that exists to replace your income for your family often belongs personally, even when estate-oriented permanent coverage belongs in the corporation.
The corporate structure earns its keep on permanent policies with an estate destination, where the CDA exit and the cheap funding dollars compound over decades. Term coverage protecting a young family's living costs is a different instrument: personally owned, it pays the beneficiary directly, immediately, outside the corporation and outside these mechanics entirely. Nothing about the arithmetic above requires moving every policy into the corporation, and a common structure is both at once, personal term for the family, corporate permanent for the estate. Which mix fits is the suitability conversation described in financial planning for physicians.
Getting the structure right at issue
The direct answer: the funding advantage is captured at the application, not repaired afterward, with four details done in order.
The corporation is named as owner and beneficiary on the application itself. The board resolution authorizing the policy is passed and filed with the minute book. The premiums flow from the corporate account, never a personal one reimbursed later. And the illustration the policy was placed on is kept for reference, while any future transaction, a withdrawal, a collateral assignment, or a capital dividend election, is checked against the insurer-confirmed ACB at that time rather than the projected column in the issue illustration; the CDA credit at death is computed from the actual ACB immediately before death. None of this is difficult; all of it is easier than the cleanup when a policy has to be transferred into or out of a corporation later, which is a disposition under section 148 with tax consequences of its own.
The numbers to keep
About $64,600 of corporate earnings to fund a $30,000 premium personally at top rates; about $33,800 for the corporation to pay it directly; roughly $30,800 of pre-tax earnings saved per year at that bracket, and much less at lower ones. Generally not deductible from either pocket, apart from the narrow collateral-loan exception. Never the mixed structure without advice: subsection 15(1) turns it into the priciest option on the menu. And the exit that completes the case: death benefit less ACB, through the capital dividend account, tax-free by election.
