You incorporated. You maxed the RRSP most years. You left money in the corporation because that’s what everyone said to do.
So why does it feel like the corporation is getting richer and you aren’t?
That isn’t a discipline problem. It’s a structural one, and there are two pieces to it.
Problem one: the RRSP was never built for you
RRSP room is 18% of last year’s earned income, capped at a dollar limit. For 2026 that cap is $33,810.
Watch what the cap does as a practice grows.
At $150,000 of T4 income, you’re sheltering the full 18%. At $250,000, that same $33,810 is 13.5% of what you earned. At $350,000, it’s 9.7%.
The more successful you get, the smaller the share of your income the RRSP actually shelters. Nothing went wrong. The ceiling just doesn’t move with you.
Problem two: where the leftover money goes
Money kept in the corporation past the RRSP limit doesn’t disappear. It becomes corporate investment income.
In BC that’s taxed at roughly 50.67% combined. Part of it is refundable eventually, but only once you pay it out as a dividend, and in the meantime it’s an unfriendly rate to be earning at. Worse, passive income above a threshold starts grinding down your access to the small business rate on the active income you’re still working for.
So the pile of cash you’re keeping for later is quietly raising the tax on the work you’re doing now.
The thing nobody showed you
There’s a second registered plan in the Income Tax Act, and it’s a defined benefit pension plan built around one person. You.
An RRSP works forward: put money in, hope it grows, and whatever it grew to is your retirement. An Individual Pension Plan works backward from a promise. Two percent of your best-three-years average salary, per year of service, capped by the CRA’s defined benefit limit — $3,932.22 per year of service for 2026, which works out to roughly a $196,600 salary ceiling per year.
An actuary calculates what has to go in to fund that promise. Your corporation contributes it. Your corporation deducts it. You never personally contribute a cent.
Why the gap opens up after forty-five
RRSP room is flat. It’s the same $33,810 whether you’re thirty-five or sixty.
IPP room is age-weighted, and the logic is almost obvious once you hear it. The closer you are to retirement, the less time the money has to grow, so the actuary needs a bigger contribution to fund the same promised pension.
That’s why it’s sometimes described as a young plan for an older participant. It’s worth a look from about forty, and it becomes substantial from forty-five on.
What that looks like with real numbers
Here’s a sample case: an incorporated professional at fifty-eight with a $700,000 RRSP and twenty-seven recognised years of past service.
Initial IPP funding comes to $840,900. Of that, $532,000 is a qualifying transfer straight out of the existing RRSP, and $308,900 is a past-service contribution the corporation deducts. That’s a large one-time deduction in year one, and it’s the part most people have never heard of.
Then the ongoing contributions:
| Period / Age | T4 income | IPP contribution | RRSP room | The gap |
|---|---|---|---|---|
| T4 income | IPP contribution | RRSP room | The gap | |
| Year 1, age 58 | $200,000 | $51,000 (25.5%) | $30,780 | +$20,220 |
| Year 4, age 61 | $235,099 | $63,476 (27.0%) | $35,240 | +$28,236 |
| Year 8, age 65 | $291,662 | $84,582 (29.0%) | $42,207 | +$42,375 |
The IPP contribution grows as a share of income every year. The RRSP stays pinned at 18% and the dollar cap. The gap compounds for as long as the plan runs.
By sixty-five in that same case: $2,220,700 in the IPP producing $145,700 a year of pension, against $1,348,800 on the RRSP path producing roughly $80,100. Call it $871,900 more in assets and $65,600 a year more income.
A separate illustration for someone starting at fifty, with past service redeemed, put the advantage at about $925,000 by sixty-five.
Both of those are illustrations with assumptions attached, and I’ve put every assumption at the bottom. Your actuary will produce a different number using current prescribed rates. But the shape holds.
What happens when you turn it on
Three choices at retirement, and the third is usually the good one.
Wind it up and roll it over into a LIRA, then a PRIF or LIF. Or take the cash, which is fully taxable and rarely the right call.
Buy a life annuity. An insurer pays a fixed income for life. In the sample case that was $96,267 a year, though annuity pricing depends entirely on interest rates on the day you buy.
Keep the plan and pay yourself the pension. The balance carries on growing tax-deferred and you draw the formula income directly. In that same case, $145,700 a year rather than $96,267.
Five things that come with it and aren’t on the brochure
Creditor protection. Pension assets are generally exempt from seizure, and pension-law protection tends to be more consistent than RRSP protection, which varies by province.
Pension income splitting with a spouse at any age. RRIF income only splits after sixty-five.
If markets underperform, the corporation makes up the shortfall — and deducts it. On the RRSP path, you absorb it and retire on less.
The plan’s actuarial and administration fees are paid and deducted by the corporation.
And it takes retained earnings off your corporation’s balance sheet, which matters if you ever sell the practice.
Who it doesn’t suit
Be honest about this part. An IPP is locked in and it’s more complicated than an RRSP. There’s an actuary, annual filings, and a plan you can’t casually unwind.
You need to be incorporated, and to have been for a while. You need to be paying yourself T4 salary — pure dividends create no RRSP room and no IPP room either, which catches a lot of people who were told dividends were always better. You want steady or growing income, and you want to be comfortable trading flexibility for a formula.
If you’re thirty-five, an RRSP is probably still your answer. If you’re fifty-two, incorporated, taking salary, and watching the corporation’s investment account grow while your RRSP room stays flat, this is worth an afternoon.
What it takes to find out
A short member profile and your T4 history produce a personalised illustration in a couple of days. If it’s worth doing, registration with the CRA takes about two weeks to file and a few months to approve, and the RRSP transfer and first contributions happen within ninety days of that.
Pull your last notice of assessment and find the RRSP deduction limit. Then find your T4 income for the same year. Divide one by the other. If the answer is meaningfully below 18%, the ceiling is already costing you, and it will cost you more every year you stay successful.
