Every owner-manager of an incorporated business in Alberta or BC eventually faces the same question: when the company is profitable, should I pay myself enough salary to fund an RRSP, or leave the money inside the corporation to invest and grow? Both routes are legitimate. Neither is universally "right." The answer depends on how you weigh three things that pull in different directions — tax deferral, integration, and flexibility.
This post lays out the trade-off in plain terms so you can have a more informed conversation with your advisor, rather than defaulting to whatever you did last year.
First, the one hard number: your RRSP room
Before weighing the trade-off, you need to know how much RRSP room your salary actually buys. The RRSP deduction limit is 18 percent of your prior-year earned income, up to the annual RRSP dollar maximum, less any pension adjustment.
The annual dollar maximum is set each year:
- 2026 RRSP dollar limit: $33,810
- 2025 RRSP dollar limit: $32,490
Source: CRA — MP, RRSP, DPSP, TFSA limits and the YMPE and CRA — RRSP deduction limit and contribution room.
One implication that owners frequently miss: dividends are not earned income, but salary is. If you pay yourself entirely in dividends, you generate no new RRSP room. To hit the 2026 maximum contribution, you generally need roughly $187,800 of prior-year earned income (because 18 percent of that reaches the $33,810 cap). The decision to fund an RRSP therefore starts with a decision to pay salary.
Route one: salary into an RRSP
When you pay yourself salary and contribute to an RRSP:
- The salary is deductible to the corporation, reducing corporate taxable income.
- The salary is taxable to you personally, but the RRSP contribution gives you an offsetting deduction.
- Inside the RRSP, investments grow tax-sheltered until withdrawal.
- On withdrawal (typically in retirement), amounts are taxed as ordinary income — ideally at a lower rate than during your peak earning years.
The RRSP is, in effect, a personal tax-deferral vehicle: deduct now, grow sheltered, pay tax later, hopefully at a lower rate.
Route two: leave it in the corporation
When you leave profits inside the company instead:
- The corporation pays corporate tax on the income first, then invests the after-tax amount.
- Investment income earned inside the corporation is taxed under the corporate rules each year — it does not grow tax-free the way RRSP investments do.
- The money comes out to you later as salary or dividends, taxed at that point.
The appeal here is tax deferral at the corporate level and flexibility: profits left in the company are capital you control, available for reinvestment in the business, to weather a downturn, or to fund a future opportunity — not locked inside a registered plan with withdrawal rules.
The three forces you are actually weighing
Tax deferral
Both routes defer tax, but in different ways. The RRSP defers personal tax until withdrawal and shelters growth completely along the way. Retaining earnings defers the personal tax that would arise on extracting them, but the investment growth inside the corporation is taxed annually. Which deferral is more valuable depends on your investment horizon, the type of returns, and your expected future tax rates.
Integration
The Canadian tax system is built on a principle called integration — the idea that income earned and then distributed through a corporation should bear roughly the same total tax as income earned directly by an individual. In a perfectly integrated world, it would not matter which route you choose. In practice, integration is approximate, not exact, and the small mismatches — which vary by province and by income type — are part of what tips the decision one way or the other. This is why Alberta and BC owners can reach different conclusions: the provincial rates feed into the integration math.
Flexibility
This is the most under-weighted factor. An RRSP is locked — your money is in a registered plan with contribution caps and withdrawal consequences. Retained corporate earnings are flexible — they are working capital you can redeploy into the business, use to smooth income across high and low years, or hold against risk. For an owner whose business is still growing or capital-hungry, that flexibility can outweigh a marginal tax advantage. For an owner who wants forced retirement saving and tax-sheltered growth, the RRSP's discipline is a feature, not a bug.
How owners usually resolve it
There is rarely a single winner; most owners use both deliberately:
- Pay enough salary to generate RRSP room and fund contributions up to the limit (the $33,810 maximum for 2026), capturing tax-sheltered growth and building personal retirement assets outside the business.
- Retain additional profits in the corporation for reinvestment, working-capital resilience, and the deferral and flexibility that brings.
- Revisit the mix annually, because earned income, the RRSP dollar limit, your business's cash needs, and the integration math all shift from year to year.
The capital gains inclusion rate sitting at 50 percent is part of the backdrop when the retained funds are eventually invested and realized — another reason the right blend is a year-by-year judgment, not a permanent setting.
Key takeaways
- Funding an RRSP requires salary (earned income); dividends generate no RRSP room.
- The 2026 RRSP dollar limit is $33,810 (up from $32,490 in 2025), and your room is 18 percent of prior-year earned income up to that cap, less any pension adjustment.
- The RRSP offers tax-sheltered growth and a personal deferral; retained corporate earnings offer corporate-level deferral and flexibility as redeployable capital.
- Integration means the choice is often close — and slightly different in Alberta versus BC — so the optimal mix is a personalized, annual decision.
If you want this modelled for your own numbers — earned income, salary-versus-dividend mix, RRSP room, and the cash your business actually needs — RN Canada works with Alberta and BC owners to set a remuneration plan that balances tax deferral, integration, and flexibility rather than defaulting to last year's split.
