The shelter debate

I’m often asked whether it’s better to save in a TFSA or an RRSP. Both are effective vehicles and each can play an important role in long-term wealth building. But when the goal is maximizing retirement security over a timeline that extends several decades into one’s elderly years, the decision is rarely as simple as assuming tax-free withdrawals make the TFSA the better option, even for average income earners.

Recent data from Statistics Canada shows a clear shift in how Canadians are saving. More people are prioritizing TFSAs over RRSPs, contributing more and using them more often. The appeal is easy to see. TFSAs offer tax-free growth and withdrawals, flexible access to savings when needed, and the opportunity to recontribute withdrawn amounts in future calendar years.

In 2023, 11.3 million Canadians made a contribution to either an RRSP or a TFSA. Of this group, 5 million contributed only to a TFSA, with a median contribution of $6,500, matching the annual contribution limit for the year. By comparison, 3.8 million tax filers contributed exclusively to an RRSP, with a median contribution of $3,420. Another 2.5 million Canadians contributed to both account types, with median contributions of $5,000 to RRSPs and $6,150 to TFSAs. Overall, the data suggests that for many households, the TFSA has become the primary vehicle for savings.

This growing preference has led many people to assume that the TFSA is generally superior to the RRSP. While that can be true in certain circumstances, particularly for short- or medium-term goals, the comparison changes meaningfully when maximizing retirement income is the sole focus and the time horizon spans multiple decades.

When your tax rate is the same at the time of contribution and at the time of withdrawal, RRSPs and TFSAs produce the same after-tax outcome.

Here’s an example to illustrate this:

Assume you’re in a 30% marginal tax bracket today and remain in a 30% bracket in retirement. You earn a long-term return of 6% annually for 30 years. You contribute $10,000 pre-tax to an RRSP and $7,000 after-tax to a TFSA, which represents the same after-tax cost as the RRSP contribution.

In the RRSP, the $10,000 contribution grows to approximately $57,435 over 30 years. When you withdraw the funds at a 30% tax rate, you pay $17,231 in tax, leaving you with about $40,204 after tax.

In the TFSA, the $7,000 contribution grows to approximately $40,204 over the same period. Because TFSA withdrawals are tax-free, you keep the full amount.

In this scenario, both approaches leave you with roughly $40,204 after tax. When the tax rate you face at withdrawal is the same as when you made the contribution, the RRSP’s upfront tax deduction and the TFSA’s tax-free withdrawal effectively offset one another.

The difference between the two really starts to matter when tax rates change between contribution and withdrawal years, when the timing of tax payments differs, or when other parts of the tax system come into play.

Why you should have both TFSA and RRSP

Over longer retirement time horizons, RRSP withdrawals during retirement may be taxed at a lower effective rate than when contributions were made, particularly if retirement income is lower than employment income. In the example above, if RRSP withdrawals were taxed at 20% rather than 30%, the RRSP would outperform the TFSA.

Another advantage of RRSPs comes from how the tax system is structured. Each year, individuals can earn income up to the basic personal amount without paying federal tax. In 2026, that amount is $16,452 and it is indexed to inflation. In years with little or no other income, such as the early years of retirement before CPP and OAS begin, this can allow RRSP or RRIF withdrawals up to that level to be taken with little or no tax owing.

Because RRSP contributions are made with pre-tax dollars, this effectively means that part of those withdrawals may never be taxed at all. This advantage does not apply to TFSAs, where tax has already been paid before contributions are made. Over very long time horizons, this feature alone can create a meaningful and often overlooked advantage for the RRSP.

There is also an additional tax advantage once an RRSP is converted to a RRIF. After age 65, RRIF withdrawals qualify for pension income splitting, giving couples meaningful flexibility to shift income from a higher-tax spouse to a lower-tax spouse. At the same age, RRIF income also becomes eligible for the pension income tax credit, further reducing taxes in retirement. When combined with the age credit, these features often allow RRSP and RRIF withdrawals to be taxed at much lower effective rates than many people expect.

RRSP contributions can also provide advantages earlier in life for families with children. Because eligibility for the Canada Child Benefit is based on net family income, contributing to an RRSP can increase CCB payments by lowering taxable income. For many households, this effectively boosts the after-tax value of an RRSP contribution.

None of this is meant to diminish the value of a TFSA. It remains highly valuable for liquidity, managing taxable income in higher-income retirement years, and limiting government benefit clawbacks. In practice, a well-designed retirement strategy almost always makes us of both TFSAs and RRSPs, using each where it provides the most value.

In summary, RRSPs should not be considered as a secondary option to the TFSA. For those focused on maximizing after-tax retirement income over the long term, RRSPs deserve more consideration than they receive. In practice, the strongest retirement strategies make use of both accounts. A common and effective approach is to contribute to an RRSP and use the resulting tax refund to fund a TFSA, allowing savers to benefit from the strengths of each.
