Short answer: My view is that an RRSP should not be the default for an incorporated owner. To contribute, you pay yourself salary first, and the money comes out of the corporation, where it was already taxed at a low rate. The RRSP defers personal tax, you pay it back when you withdraw at whatever your rate is then, and at death the whole balance is taxed in one year. For many owners, leaving the profit in the corporation and giving it a job there does more. It still fits for some owners, and I list who below. Think of the money as needing a defence job (protection from tax, creditors and a bad market year) and an offence job (growth and access). The RRSP is mostly a tax deferral. A contract owned by the corporation can do both jobs.
Why is the RRSP different for an owner than for an employee?
An employee gets RRSP room from employment income, and a payroll deduction or a refund does the rest. It is a simple, well-understood tool, and for a high earner in a top bracket it can work well.
An owner has a choice that an employee does not. Profit can stay in the corporation, or it can come out. RRSP room is created by earned income, which means salary. Dividends do not create room. So to contribute, the corporation has to pay you salary, you contribute, and you deduct. The real question is what that route costs compared with leaving the profit where it is, and whether you already take more salary than you spend. Salary you live on cannot also go into the RRSP. To contribute, you have to pay yourself more than your living costs, and that extra salary is taxed to you, with only the contributed part deducted. Money that could have stayed in the corporation at the small business rate ends up taxed personally.
What does the RRSP do well?
Money goes in before tax. A $10,000 contribution comes off your taxable income, so the full $10,000 is invested, and it grows from that larger number. If you invested after tax instead, you would start with less. The deduction is certain and immediate, the account is simple and low cost, and many owners already use it.
The cost shows up later. Withdrawals are taxed as income at your rate that year. An RRSP does not survive death intact. Unless it rolls to a spouse or certain dependants, the full balance is added to your final return as income, all at once, and your estate pays the tax, usually at the highest rates. Naming a beneficiary does not change that. All the deferral can be given back in one year. The next section covers what it costs to get the money in from a corporation.
What does it cost to fund an RRSP from the corporation?
Here is how each step works.
- Salary is deductible to the corporation, so the corporation's tax on that profit goes away. That part is a benefit.
- Room is 18% of salary, up to an annual limit. To create $18,000 of room you need $100,000 of salary. Only the $18,000 you contribute gets the deduction. The other $82,000 is taxed to you as ordinary salary, whether you needed the cash or not.
- The deduction is only worth your marginal rate. The full top combined Ontario rate (over 53%) applies only above approximately $250,000 of taxable income. At a $100,000 salary the deduction is worth a much lower rate, so you defer less tax than the top-bracket picture suggests.
- Salary carries Canada Pension Plan contributions on both the employee and employer side. The RRSP deduction does not offset CPP.
- The money is locked into a registered account. Withdrawals are fully taxable as income in the year you take them. At death, the full balance is taxed as income on your final return, all at once, and your estate pays it, unless it rolls to a spouse or certain dependants.
Compare that with leaving the profit in the corporation. It is taxed at the small business rate on the first $500,000 of active income (11.2% combined in Ontario since July 1, 2026, down from 12.2%). That leaves more working dollars to invest or deploy today. Investment income inside the corporation is taxed annually at a high rate, partly refundable when dividends are paid, and the $50,000 passive income threshold applies. See whether to invest inside your corporation or take the money out.
Neither route is free. This is a comparison, and the answer depends on your numbers.
What is the bet inside an RRSP, and how is it different for an owner?
The bet itself applies to anyone who contributes, employee or owner. An RRSP is a tax deferral. You get the deduction now and pay the tax later, and it works best when you pay less on the way out than you saved on the way in. That is a bet on two things. One is that you will take less income out in life than you are earning now, so your withdrawal rate is lower than your deduction rate. The other is that tax rates will not be higher by then. If your retirement income is large, because you have rental income, corporate dividends, a pension, or an RRSP that grew bigger than you planned, or if rates rise, the gap shrinks or reverses. Being wrong has a second cost. The money was locked away during the years you were younger and healthier, and you cannot get those years back.
What is different for an owner is the choice. An employee's alternative to the RRSP is spending the money or investing it after tax. An owner has another option, which is leaving the profit in the corporation, and that route has its own bet. It assumes the corporation keeps its low rate on active income, that passive income stays manageable under the $50,000 threshold, and that you can get the money out later at a personal tax cost you can live with. A long-term contract inside the corporation assumes you can carry the premiums for the funding period.
So for an owner the question is not whether to take a bet. It is which bet you would rather make, and which one you are better placed to be wrong about.
When does the RRSP still fit?
- You are already paying yourself a high salary and sit in the top bracket, and you expect to draw a much lower income in retirement.
- You need to take a lot of money out of the corporation every year, in the range of $250,000 or more, and cannot find a way to leave funds in it. Your salary is high regardless, you are in the top bracket, and the contribution earns the full top-rate deduction. This is where the RRSP makes the most sense. The RRSP is a by-product of how you already pay yourself. Extracting more only to claim the deduction is a different decision, and it is the one that costs the most.
- You want a simple, low-cost structure and do not want to commit to a long-term premium.
- You want to use spousal RRSP contributions to split income later.
- No one connected to the corporation can be insured at a reasonable rating, or you do not want insurance as part of the plan. The corporation can own a policy on a shareholder, and in some cases on a spouse, a child, a partner or a key employee, as long as there is an insurable interest and the person consents.
- Your corporation does not earn enough profit to leave much behind after paying your own salary.
What is the alternative?
Leaving profit in the corporation and putting part of it into a participating whole life contract owned by the corporation is one of the options some owners use. I set these up, so I also know where they do not fit.
| RRSP funded by salary | Corporate-owned participating whole life | |
|---|---|---|
| How it is funded | Salary, taxed to you, offset by the RRSP deduction | Corporate after-tax profit. Premiums are not deductible |
| Tax on growth | None while inside the RRSP | Generally not taxed each year inside an exempt policy |
| Tax when you take money out | Fully taxable as income at your rate that year | Borrowing is possible. Policy loans above cost basis can create tax. A bank loan against the policy carries interest |
| Access | Withdraw and pay tax | Borrow against it, or surrender |
| At death | Full balance taxed as income on the final return, all at once, paid by the estate, unless it rolls to a spouse or certain dependants | Death benefit paid to the corporation tax-free, with a capital dividend account credit |
| What drives the growth | Markets. It can go down as well as up | The contract. In the contract I set up, cash value rises every year as long as the premium is paid. Dividends add to it |
| Commitment | Voluntary, flexible | Premiums for the funding period. Cash value builds a little more each year and varies by design |
I am not saying one wins every time. The contract gives you things the RRSP does not: a death benefit, contractual cash value growth that does not depend on the market, and a way to reach the money without a taxable withdrawal. The RRSP gives you things the contract does not: flexibility, a lower cost, and market upside if you can live with the swings. The page on corporate-owned life insurance covers who the contract does not suit.
Related questions people ask
I have been maxing my RRSP for years. Was that a mistake?
No. What you did made sense on the information most people are given, and the tax deduction was real. The question now is about the next dollar, and about how you plan to take the money out. Do not stop or collapse anything based on a web page.
Do I have to pay myself salary to contribute?
Yes. RRSP room comes from earned income, and dividends do not count. Many owners pay themselves dividends only, which is a reason some owners have little or no room.
What happens to my RRSP when I die?
It does not pass tax-free. The full balance is added to your final return as income, all at once, and your estate pays the tax. The exception is a rollover to a spouse or certain dependants, which defers the tax to them. Naming a beneficiary directs the money. It does not remove the tax. For a large balance that can be a very large tax bill in one year.
Is the RRSP ever the better choice for an owner?
Yes. See the list above. The better choice depends on your income now, your expected income later, how much access you want and whether anyone connected to the corporation can be insured. An owner with a short horizon, modest profit or a high expected retirement income can reasonably prefer it.
What should I do first?
Decide what the money is for and when you want cash flow from it. Then compare the options on your own numbers. See what to do once your RRSP and TFSA are maxed.
