Why contribute to an RRSP?
A registered retirement savings plan (RRSP) provides short and long-term tax advantages that can help fund the retirement you want.
You can also use money from your RRSP to help buy your first home or fund education for you or your spouse. If you use RRSP funds for these purposes, you must repay them to your RRSP. Any funds you repay to your RRSP aren’t considered contributions and won’t generate a tax refund.
What is the RRSP contribution deadline?
March 3, 2025 is the last day to contribute to you or your spouse’s RRSP to claim a deduction on your 2024 tax return.
RRSP contribution strategies
Lump-sum deposit
This strategy is often where new investors begin. Simply use any amount you have saved somewhere and contribute it to your RRSP. You’ll get a tax deduction in the year you contributed.
In the example below, you’ll notice we mention the marginal tax rate. In Canada, as your income increases, so does your tax rate. Your marginal tax rate is the highest tax bracket (and corresponding rate) that applies to your last dollar of income.
Example:
- Initial RRSP contribution: $5,000
- Tax refund based on marginal tax rate of 30%: $1,500
- Total RRSP contribution: $6,500
The above example is for illustrative purposes only. Situations will vary according to specific circumstances. To determine specific marginal tax rate, see Government of Canada.
Reinvest your tax refund
This strategy takes the lump-sum strategy up a notch by also contributing the tax refund generated by your original RRSP contribution. This will provide a tax deduction in the year you contribute the tax deduction to your RRSP.
Catch-up loan
In addition to your lump-sum contribution, you can take out an RRSP loan to maximize your contribution and use up your available contribution room as specified on your Canada Revenue Agency (CRA) notice of assessment. You can use the tax refund to help pay back the loan. Depending on the size of the loan, this can take up to a few months or years.
You may want to use this strategy if you’re having a particularly high-income earning year because the bigger tax deduction will help reduce the potentially larger amount of income tax you’ll be paying.
Example:
- Initial RRSP contribution: $5,000 (client’s investment) plus $5,000 (loan) = $10,000
- Tax refund based on marginal tax rate of 30%: $3,000
- Total RRSP contribution: $10,000
The above example is for illustrative purposes only. Situations will vary according to specific circumstances.
If you’re concerned about paying back your RRSP loan, you can also borrow an amount equal to the expected tax refund before you make your contribution, then use the actual tax refund to repay the loan.
However, to apply this strategy, you need to know how much you want to contribute, your marginal tax rate, and how much you expect your refund to be based on your RRSP contribution. You’ll also need access to an RRSP line of credit to borrow the expected refund amount so you can contribute the full amount into the RRSP. You can use the formula below to calculate how much to borrow, or leave it to your advisor or tax professional to figure it out for you.
(RRSP contribution amount multiplied by marginal tax rate) divided by (1 minus marginal tax rate) = gross-up amount to borrow
Example:
- Expected tax refund: $5,000 multiplied by 30% = $1,500
- Gross-up amount to borrow: $1,500 divided by (1 minus 30%) = $2,143
- Total RRSP contribution: $5,000 plus $2,143 = $7,143
- Initial RRSP contribution: $7,143
- Tax refund based on marginal tax rate of 30%: $2,143
- Total RRSP contribution: $7,143
The above example is for illustrative purposes only. Situations will vary according to specific circumstances.
Important considerations when borrowing to invest
There’s always a risk when using borrowed money to invest. Leveraging magnifies gains or losses. It is important that you understand a leveraged purchase may involve a greater risk than a purchase using cash resources only.
- Interest charges should be minimal, as the loan is expected to be outstanding for only a few months at the most.
- The interest when borrowing to invest in an RRSP isn’t deductible.
- You shouldn’t spend your tax refund. Instead, you should use it to pay off the loan to avoid more interest charges.
