TFSA and RRSP Can Work Together: How Income Changes May Create Long-Term Tax Savings

Many Canadians contribute to either a TFSA or an RRSP each year. But relatively few people think carefully about a simple question: the same dollar can create very different tax results depending on which account it enters and at what stage of income.

According to an analysis by Financial Post columnist and portfolio manager John De Goey, people whose income is expected to rise quickly may consider using the TFSA first during lower-income years, and then shifting part of those funds toward RRSP contributions once they enter a higher tax bracket.

The point of the strategy is not to say that TFSA is always better than RRSP, or that RRSP is always better than TFSA. The real point is timing. The value of a contribution can change when income changes. De Goey describes this type of planning as “tax arbitrage.”

TFSA and RRSP do not have one universal order. The right sequence depends on income level, marginal tax rate, future income growth, retirement planning, family responsibilities, and cash-flow needs.

How TFSA and RRSP Tax Benefits Differ

TFSA and RRSP are both common registered accounts in Canada, but their tax logic is almost opposite.

TFSA: No deduction today, tax-free growth and withdrawals later

A TFSA uses after-tax income. Contributions do not reduce taxable income in the year of contribution. However, interest, dividends, and capital growth inside the account are generally not subject to Canadian income tax, and eligible withdrawals are not included in taxable income.

The 2026 annual TFSA limit is $7,000. For someone who has been eligible every year since 2009 and has never contributed, the total cumulative room in 2026 is $109,000. A person’s actual available room still depends on age, Canadian tax residency, contribution history, withdrawal history, and CRA records.

TFSA also offers flexibility. Withdrawals are generally added back to contribution room in the following calendar year, not immediately. That means anyone withdrawing and recontributing in the same year must confirm that they still have available room, or they may create an overcontribution.

RRSP: Deduction today, taxable withdrawals later

RRSP contributions can be used to reduce taxable income in the contribution year. Investments inside the RRSP grow on a tax-deferred basis, but future withdrawals from an RRSP or RRIF are usually included in taxable income.

Annual RRSP contribution room is generally based on prior earned income and can be affected by pension adjustments, unused room, and other factors. The 2026 RRSP dollar limit is $33,810, but the amount an individual can contribute and deduct should be confirmed through their CRA Notice of Assessment or My Account.

TFSA After-tax contributions; eligible growth and withdrawals are generally tax-free

RRSP Deduction today; future withdrawals are generally taxable

Timing Account order should reflect income stage and marginal tax rate

In simple terms, TFSA uses money that has already been taxed and then allows eligible growth and withdrawals to be tax-free. RRSP provides a tax deduction today, but withdrawals are taxed later.

The Key to Tax Arbitrage: Save RRSP Room for Higher-Income Years

Canada uses a progressive income tax system. As income rises, additional income is usually taxed at a higher marginal rate, taking into account both federal and provincial tax rates.

The value of an RRSP deduction is closely tied to the contributor’s marginal tax rate in that year.

Suppose someone contributes $10,000 to an RRSP during a lower-income year when their combined marginal tax rate is 25%. The theoretical tax savings would be about $2,500.

If the same $10,000 deduction is used in a future year when the combined marginal tax rate is 40%, the theoretical tax value could rise to about $4,000.

In both cases, the RRSP contribution amount is the same. But because the deduction is used in different income years, the immediate tax benefit is different.

This is the core idea behind the strategy. During lower-income years, it may make sense to build TFSA assets first. When income rises, RRSP room may become more valuable because the deduction can offset income taxed at a higher marginal rate.

However, this does not mean low-income years should never involve RRSP contributions. Personal circumstances such as employer matching, the Home Buyers’ Plan, child benefits, future retirement income, pensions, debt, and short-term cash needs can all affect the decision.

Stage One: Build TFSA Assets During Lower-Income Years

The original analysis uses a nine-year example involving a professional whose income rises quickly.

Assume a person currently earns $70,000 a year and expects income to rise gradually to $100,000 over the next few years. During the first four lower-income years, instead of using large amounts of RRSP room immediately, the person prioritizes TFSA contributions.

The example contribution pattern is:

Year	Income	TFSA Contribution	Cumulative TFSA Principal
Year 1	$70,000	$7,000	$7,000
Year 2	$80,000	$7,500	$14,500
Year 3	$90,000	$7,500	$22,000
Year 4	$100,000	$7,500	$29,500

This is a simplified example used to explain the strategy. It does not represent officially announced TFSA limits after 2026. CRA has confirmed the 2026 TFSA limit at $7,000; future annual limits should be checked against official government announcements.

After four years, the TFSA has received $29,500 in principal contributions. If the money has been invested, the account value may also be higher than the contributed principal.

This pool of TFSA capital serves two purposes. It can continue growing in a tax-free environment, and it can later help fund larger RRSP contributions when income rises.

Stage Two: Increase RRSP Contributions as Income Rises

Starting in year five, the person’s income rises more quickly, moving from $125,000 toward $200,000.

As the marginal tax rate increases, the immediate value of RRSP deductions becomes more meaningful. At this stage, the person reduces TFSA contributions and uses both new savings and some TFSA withdrawals to make larger RRSP contributions.

The example includes the following sequence:

Year 5: Income of $125,000

The person contributes $8,000 to the RRSP, reducing taxable income to about $117,000 and limiting the amount of income exposed to a higher federal tax bracket.

Year 6: Starting to use TFSA funds

As income continues to rise, the person uses current-year savings and begins withdrawing from the TFSA to increase RRSP contributions.

Year 7: Income of $150,000

The person uses $16,000 in new savings and withdraws $10,000 from the TFSA, contributing a total of $26,000 to the RRSP.

Year 8: Income of $175,000

The person uses $24,000 in new savings and withdraws about $20,000 from the TFSA, further expanding RRSP contributions. By this stage, the original TFSA funds are largely used.

Year 9: Income of $200,000

TFSA funds have been used up, so the person contributes $32,000 to the RRSP directly from current income.

In this example, income grows quickly enough that after-tax disposable income may still rise even as annual savings and RRSP contributions increase. The person does not necessarily need to sharply reduce their lifestyle to execute the strategy.

Why Moving Money from TFSA to RRSP May Be More Efficient

At first glance, this may look like simply moving money from one account to another. But once the money enters the RRSP, it creates a deduction based on the contributor’s marginal tax rate in that year.

Suppose someone withdraws $20,000 from a TFSA and contributes $20,000 to an RRSP. If the combined marginal tax rate that year is 40%, that contribution could theoretically generate about $8,000 in tax savings.

If the same $20,000 had been contributed to an RRSP years earlier when the marginal tax rate was 25%, the tax savings may have been only about $5,000.

The difference is about $3,000. If a similar approach is used over several years, the cumulative tax difference could reach tens of thousands of dollars.

In addition, the $20,000 withdrawn from the TFSA is generally added back to TFSA contribution room the following year. In the future, once income rises further and RRSP contributions approach the individual’s limit, the TFSA can potentially be rebuilt.

A tax refund does not automatically make someone wealthier. To make the strategy effective, refunds should ideally be reinvested, used to reduce debt, or used to rebuild registered accounts rather than simply increasing consumption.

Who May Be Better Suited for This Strategy?

This two-stage strategy may be more suitable for people with a clear path of rising income, such as:

young professionals entering a field where income is expected to rise quickly;
salespeople whose commission income is growing over time;
consultants or self-employed professionals whose client base is expanding;
younger managers with a relatively clear promotion path;
real estate agents or business owners whose early income is modest but may rise significantly in several years.

The common feature is that current income is low or moderate, but there is a reasonable expectation of entering a higher tax bracket in the future.

The strategy also requires savings discipline. If every $10,000 of additional income leads to $10,000 of additional spending, there may not be enough money left to execute account transfers and continue investing.

Who May Not Be a Good Fit?

For people whose income is stable, slow-growing, or likely to be similar in retirement, the tax-rate difference may not be meaningful.

If someone is already in a high tax bracket, delaying RRSP deductions may mean giving up valuable tax savings today. If an employer provides RRSP matching contributions, it is usually not wise to give up free employer money simply to wait for higher income later.

People receiving benefits tied to family net income should also be careful. RRSP deductions can affect benefit calculations, while future RRSP or RRIF withdrawals may affect Old Age Security or other income-tested benefits in retirement.

TFSA withdrawals also restore contribution room only in the following year. If someone withdraws and recontributes in the same year without enough remaining room, an overcontribution may occur.

For these reasons, De Goey also emphasizes that this strategy has important limitations. It is not a fixed formula for all Canadians.

The Real Value of TFSA and RRSP Comes from Investing and Long-Term Compounding

Many people think of TFSA as a tax-free savings bank account and RRSP as a temporary tax-season deposit used to receive a refund. In reality, both are account structures. The long-term result depends on what assets are held inside the accounts and how long the money remains invested.

TFSA can hold eligible stocks, bonds, funds, and segregated funds. Through licensed segregated fund agents, Ai Financial clients may use TFSA, RRSP, and other account types to hold segregated funds based on their objectives and personal circumstances.

Account sequencing can improve tax efficiency, but contribution room and refunds alone do not create long-term wealth. If money sits in cash for years and earns less than inflation, the account may be tax-efficient while still missing long-term growth opportunities.

Ai Financial believes there is no single correct order for TFSA and RRSP. Income, assets, debt, family responsibilities, future income changes, and retirement goals all matter. More importantly, people should start investing early, contribute consistently, use suitable allocation, and give compounding enough time to work.

For young people whose income is expected to rise quickly, building TFSA assets first and then increasing RRSP contributions in higher-income years may improve overall tax efficiency. But before applying the strategy, individuals should verify their CRA contribution room, consider provincial tax rates, review their broader financial situation, and discuss the plan with qualified tax or financial professionals.
