Individual Pension Plan (IPP) vs RRSP for Business Owners

For an incorporated business owner choosing where to put retirement savings, an individual pension plan (IPP) and an RRSP answer the same question in very different ways. An IPP is a defined-benefit pension that your corporation establishes and funds on your behalf. For owners who are older, pay themselves high and steady T4 salary, and have surplus cash in the company, an IPP generally permits larger tax-deductible contributions than an RRSP. In exchange, it costs more to run and offers less flexibility.

This article is for incorporated owners and professionals in Ottawa and across Ontario who already contribute to an RRSP and wonder whether an IPP would let them do more. It explains how the two compare and who tends to benefit, not whether an IPP is right for you specifically. That answer depends on your age, your salary, and your corporation’s cash position, and should be confirmed with your accountant and an actuary.

What an IPP is

An IPP is a registered pension plan with a single member, usually the owner. Your corporation is the sponsor. The plan promises you a defined retirement benefit, and an actuary calculates each year how much the company must contribute to fund that promise. Because the contribution is made by the corporation, it is a deductible business expense, and the investments grow tax-sheltered inside the plan, much like an RRSP.

The defining feature is that contribution room is driven by actuarial calculation rather than a simple percentage of income. As you age, the amount needed to fund the promised benefit rises, which is why the IPP advantage grows later in your career.

How an RRSP compares

An RRSP is simpler and personal. Your deduction room is 18% of your previous year’s earned income, up to an annual maximum of $33,810 for 2026, plus any carry-forward. You contribute personally, deduct it on your personal return, and the investments grow tax-deferred until withdrawal. There are no actuaries, no corporate sponsorship, and far less administration. Our RRSP contribution limit explained guide covers the mechanics in detail.

The RRSP’s strengths are flexibility and low cost. You can contribute, pause, or skip a year freely, and you can hold almost any eligible investment. For most Canadians, the RRSP is the right and sufficient tool.

Where the IPP pulls ahead

The IPP advantage is largely a function of age and salary. Because the actuarial funding target rises as retirement approaches, an owner in their 50s can often have the corporation contribute considerably more to an IPP than the RRSP maximum would allow. The gap tends to be modest in your 40s and widens with each passing year.

Two further features add to the appeal for some owners:

• Past-service funding. When an IPP is set up, it can often recognise prior years of employment with the corporation, allowing an additional lump-sum contribution to fund that past service. This can be a meaningful one-time deduction.
• Deductible expenses and top-ups. Setup and administration costs are generally deductible to the corporation, and if plan investments underperform the assumed rate, the company may be required, and permitted, to contribute more to make up the shortfall. For an owner with surplus corporate cash, that funding obligation is a feature, because it moves more money into a tax-sheltered pension.

Who tends to benefit, and who does not

An IPP generally suits owners who:

• Are roughly 45 or older, where the contribution advantage becomes material.
• Pay themselves substantial T4 salary, since the plan is built on employment earnings.
• Have reliable surplus cash in the corporation to meet funding obligations.
• Intend to keep the corporation for years, so the administration is worthwhile.

An IPP is usually a poor fit for owners who are younger, who pay themselves mainly in dividends, who have irregular profits, or who value simplicity over the extra contribution room. If you draw dividends rather than salary, an IPP may not work at all, because there is no T4 income to base it on. The salary-versus-dividend choice therefore interacts directly with this decision; our note on salary vs. dividends for business owners is worth reading alongside this.

A simplified illustration

The table below is an illustrative, hypothetical comparison to show the shape of the trade-off, not a quote or a projection. Actual contribution limits are set by an actuary each year and vary with age, salary, and plan terms. Your own numbers depend on your situation.

Feature	RRSP	Individual pension plan (IPP)
Who contributes	You, personally	Your corporation
Where the deduction lands	Your personal return	The corporation’s return
Contribution room basis	18% of earned income to an annual cap	Actuarial funding of a defined benefit
Contribution size with age	Fixed percentage regardless of age	Rises as you approach retirement
Requires T4 salary	Helpful but flexible	Yes, built on T4 earnings
Flexibility to skip a year	High	Low; funding obligations apply
Ongoing cost	Minimal	Actuarial and administration fees
Creditor protection	Limited	Generally stronger as a pension

The IPP wins on contribution capacity and often on creditor protection; the RRSP wins on cost and flexibility. Which matters more depends entirely on your stage and your corporation.

The costs and obligations to weigh

An IPP is a registered pension plan, so it carries real administration: an actuarial valuation at setup and periodically thereafter, annual filings, and professional fees. There are also funding obligations. If the plan’s investments fall short of the assumed return, the corporation may need to top it up, which is helpful when you want to shelter more but demanding if corporate cash is tight. The plan’s assets are also generally locked in for retirement, with less access than an RRSP before then.

None of this is a reason to avoid an IPP; it is a reason to enter one only when the numbers and your cash flow support it. For the right owner, the extra deductible contributions compound into a materially larger pension. For the wrong owner, the cost and rigidity outweigh the benefit.

Fitting the decision into the bigger plan

An IPP is a retirement and tax tool, but it also touches your corporate cash strategy, your eventual exit, and your estate. Money committed to an IPP is money not available for other uses, so the decision belongs inside a broader plan that considers your retirement income as a business owner and what you intend to do with retained earnings in the company. For high-earning professionals in particular, the IPP is one of several levers, and its value is clearest when viewed against the alternatives.

Creditor protection and estate considerations

Beyond the contribution advantage, an IPP carries features that matter to some owners. As a registered pension plan, its assets generally enjoy stronger creditor protection than an ordinary RRSP, which can appeal to owners in higher-risk fields. The plan can also name beneficiaries and, depending on its terms and whether a spouse is a member, offer some flexibility in how value passes at death. These are secondary to the core decision but can add to the case for an IPP where they align with an owner’s circumstances. As always, the specifics depend on the plan and the rules in force, and should be confirmed with your advisors before you rely on them.

Next step

Whether an IPP beats simply topping up your RRSP comes down to your age, your salary, your corporation’s cash, and your timeline. It is a calculation, not a rule of thumb, and it rewards getting the numbers right. Our business-owner planning and retirement planning work is designed to answer exactly this kind of question in coordination with your accountant and, where an IPP is on the table, an actuary.
