If you earn $150,000, $200,000 or more and have unused RRSP room, you may wonder whether to contribute gradually or borrow to invest sooner. An RRSP loan can bring a contribution forward. Whether that helps depends on the tax deduction, borrowing cost, repayment plan and investment outcome—not income alone.
The practical idea is simple: borrow personally to make an eligible RRSP contribution, apply any resulting tax refund to the loan, and repay the remaining balance from cash flow. It is a financing strategy, not a perpetual-motion machine.
How the contribution-and-repayment cycle works
First confirm your available contribution room and deduction limit using your latest CRA information, adjusted for contributions not yet reflected there. Contribute within your limits, claim an appropriate deduction, and direct any resulting refund toward repayment. New borrowing should wait for a fresh review of room, debt and affordability; repaying a loan does not itself create RRSP room. CRA: contributing to an RRSP
A $30,000 example—with the assumptions visible
Assume you have at least $30,000 of available contribution room, can deduct the full contribution, and the entire deduction saves tax at an assumed 45% marginal rate:
| Item | Illustrative amount |
|---|---|
| Loan used for the RRSP contribution | $30,000 |
| Estimated tax reduction: $30,000 × 45% | $13,500 |
| Principal remaining after applying $13,500 | $16,500 |
This is an illustration, not a promised refund. A deduction may cross tax brackets. The actual refund also depends on tax already paid, other income, credits and amounts owing. The remaining principal excludes interest, fees and intervening payments.
You still owe the lender even if the investment falls. The contribution is an asset inside the RRSP; the loan is a liability outside it.
The refund should have a job before you borrow
Using a refund to reduce debt can shorten the repayment period and reduce interest costs. Spending it instead leaves more debt outstanding. Ontario's securities regulator explains that a refund can repay all or part of an RRSP loan and that regular contributions are an alternative worth comparing.

Plan for the period before the refund arrives. Payments and interest may begin earlier, and the refund may be smaller or later than expected.
Earlier investing brings opportunity and risk
Borrowing puts more money into the account sooner than waiting to save the same contribution. It also exposes that money to market losses sooner and adds financing costs. Compare the loan strategy with investing the same monthly cash flow without borrowing, using the same investment assumptions and time horizon.
RRSP investment income is generally tax-deferred while it stays in the plan; withdrawals are generally taxable. Crucially, interest on money borrowed to contribute to an RRSP is not deductible. Do not confuse this with interest rules for eligible non-registered investing. CRA: RRSPs and other registered plans
Before repeating the strategy
Review these questions each year:
- Is there verified room, and does taking the deduction now fit your tax situation?
- Can you make payments without relying on investment gains or the expected refund?
- Do you retain emergency savings and have higher-interest debts under control?
- What happens if interest rates rise, income falls or the portfolio declines?
- Has the previous loan been repaid, and would automatic monthly contributions be simpler?
An RRSP loan may fit some high-income households, especially when repayment is prompt and affordable. It is not automatically better than contributing your own cash. The aim is a stronger after-tax retirement position, supported by manageable debt.
Book a consultation to review your RRSP room, contribution timing and repayment capacity.
