The Biggest RRSP Mistakes Canadians Make

The RRSP is one of the most powerful wealth-building tools available to Canadians. It is also one of the most misused.

After working with Canadians at every income level and stage of life, we see the same mistakes repeated over and over. Here are the ones that cost people the most money.

Mistake 1: Leaving It in Cash or Low-Return Investments

The RRSP is not a savings account. It is a tax shelter — and what you put inside it matters enormously.

Far too many Canadians have their RRSP sitting in a basic savings account earning 2% to 3% interest. The tax-deferred growth of an RRSP is most valuable when the underlying investments are generating meaningful returns over time.

A portfolio of low-cost index ETFs earning 7% per year over 30 years inside an RRSP looks dramatically different from the same contributions sitting in a savings account. The difference can easily be hundreds of thousands of dollars.

Mistake 2: Contributing When Your Tax Rate Is Low

The RRSP deduction is most valuable when you are in a high tax bracket. Many young Canadians contribute aggressively to their RRSP when they are earning $45,000 to $55,000 — getting a modest tax deduction — when they would be better served building their TFSA instead and saving the RRSP room for higher-earning years.

If your income is below roughly $50,000, the TFSA is often the better vehicle. Save your RRSP contribution room for the years when your income — and your marginal tax rate — are higher.

Mistake 3: Withdrawing Early

Withdrawing from your RRSP before retirement triggers immediate withholding tax — 10% on amounts up to $5,000, 20% on amounts from $5,001 to $15,000, and 30% on amounts above $15,000. That money is also added to your taxable income for the year.

Worse, you permanently lose that contribution room. Unlike a TFSA, RRSP contribution room you use and then withdraw does not come back.

Canadians who dip into their RRSP for vacations, renovations, or other expenses before retirement pay a steep price — both in immediate tax and in lost long-term compounding.

The only legitimate early withdrawals are through the Home Buyers Plan (up to $35,000 for a first home, repayable over 15 years) and the Lifelong Learning Plan (up to $10,000 per year for full-time education, repayable over 10 years).

Mistake 4: Not Having a Spousal RRSP

If you and your spouse have significantly different income levels, a spousal RRSP can be a powerful income-splitting tool in retirement.

When you contribute to a spousal RRSP, you get the tax deduction based on your higher income. But in retirement, the funds are withdrawn by your lower-income spouse at their lower tax rate.

Over time, this strategy can shift tens of thousands of dollars from a high-tax bracket to a low-tax bracket — a real and meaningful saving.

Many Canadians ignore this strategy entirely, even though it is available to any couple.

Mistake 5: Waiting Until the Last Minute Every Year

Canadians who contribute to their RRSP in the first 60 days of the year — racing to beat the March deadline — are making a costly mistake.

Every year you wait to contribute is a year that money is not compounding inside the tax shelter. If you contribute $10,000 in February instead of the previous February, you lose an entire year of tax-deferred growth on that amount.

The best approach is to set up automatic monthly contributions throughout the year. This also gives you the benefit of dollar-cost averaging — buying investments at various price points rather than all at once.

Mistake 6: Ignoring the RRSP as an Estate Planning Tool

Large RRSP and RRIF balances at death are fully taxable as income in the year of death — unless transferred to a surviving spouse. For Canadians with significant registered savings, this can result in an enormous tax bill for the estate.

Strategic drawdown during retirement — taking more than the mandatory minimum from your RRIF in lower-income years, moving funds to a TFSA, making charitable donations of appreciated securities — can reduce the tax burden your estate faces.

This is advanced planning that most Canadians never do, but it can preserve significant wealth for the next generation.

Mistake 7: Not Tracking Your Contribution Room

Your RRSP contribution room accumulates at 18% of your previous year's earned income, up to a maximum ($31,560 in 2024). Unused room carries forward indefinitely.

Over-contributing triggers a penalty tax of 1% per month on the excess amount above a $2,000 lifetime buffer. It happens more often than you might think — especially when people change jobs and forget about pension adjustments that reduce their room.

You can always check your available RRSP room through your CRA My Account online.

The Bottom Line

The RRSP is a genuinely powerful tool. But like any powerful tool, it requires using it correctly. Avoiding these mistakes — and making deliberate, strategic decisions about when, how much, and what to invest — can dramatically improve your long-term financial outcome.
