The Question $90K Ontario Earners Get Wrong

At $90,000 of Ontario income, your marginal tax rate is approximately 43.41%. Every dollar into an RRSP saves 43.41 cents today. Every dollar into a TFSA saves nothing today โ€” but grows and withdraws tax-free forever. The right answer depends entirely on one variable: what marginal rate will you face at withdrawal in retirement?

For a $90,000 Ontario earner who expects to retire on approximately $50,000 per year, the RRSP wins by approximately $49,073 over 25 years on a $20,000 contribution โ€” when the RRSP tax refund is also invested. That is the math. Here is how it works and exactly when TFSA wins instead.

Illustrative only. Assumes $20,000 annual RRSP contribution, Ontario marginal rate 43.41% at $90K, retirement marginal rate 29.65% at $50K, 6% annual growth, 25-year horizon. RRSP refund reinvested in TFSA at same return. Results vary materially based on actual returns, income, and tax rates. Not personalized financial advice โ€” consult a licensed advisor and CPA.

๐Ÿ’ก The Break-Even Rule

RRSP equals TFSA only when your retirement marginal rate equals your current rate โ€” 43.41% in this case. If you retire on income above $90K Ontario (same or higher bracket): TFSA wins or ties. If you retire on less โ€” which is most Canadians โ€” RRSP wins. The $90K earner retiring on $50K is a clear RRSP case. Consult a licensed advisor and CPA to model your specific break-even.

When the TFSA Wins for $90K Earners

The Optimal Sequence for a $90K Ontario Earner

  1. Maximize RRSP first โ€” 43.41% deduction is the highest-leverage move at this income level.
  2. Invest the RRSP refund in TFSA โ€” the $8,682 refund on a $20,000 contribution, reinvested in TFSA at 6% ร— 25 years, adds $37,262 in tax-free wealth.
  3. Max TFSA with remaining savings capacity โ€” TFSA provides flexibility and retirement income diversification that reduces OAS clawback risk.
  4. Reassess annually โ€” income changes, bracket changes, and life events can shift the optimal balance. Consult a licensed advisor each year for an updated view.
Frequently Asked Questions
Should a $90,000 Ontario earner use RRSP or TFSA first?+

For most $90,000 Ontario earners who expect to retire on less than $90,000, the RRSP should be prioritized first. The illustrative advantage is approximately $49,073 over 25 years on a $20,000 contribution when retiring at the 29.65% Ontario bracket. Individual circumstances vary significantly โ€” consult a licensed advisor and CPA.

What is the RRSP contribution limit for 2025?+

The 2025 RRSP contribution limit is $31,560 or 18% of 2024 earned income โ€” whichever is lower โ€” plus any accumulated unused room from prior years. Your personal room is shown on your CRA Notice of Assessment and at CRA MyAccount. The 2025 RRSP deadline is March 2, 2026.

Can I contribute to both RRSP and TFSA in the same year?+

Yes. RRSP and TFSA have entirely separate contribution limits and can both be funded in the same year. In 2025: RRSP limit $31,560 (or 18% of prior earned income), TFSA limit $7,000 plus accumulated unused room. Many Canadians contribute to both โ€” RRSP for the tax deduction, TFSA for flexibility and retirement income diversification. Consult a licensed advisor for an allocation specific to your income and goals.

Does the RRSP refund really matter for the comparison?+

Yes โ€” significantly. The RRSP refund is a real cash flow that the TFSA path does not generate. In the illustrative example, the $8,682 refund on a $20,000 RRSP contribution โ€” reinvested in a TFSA at 6% over 25 years โ€” grows to $37,262. That refund alone accounts for a substantial share of the $49,073 illustrative RRSP advantage. Ignoring the refund overstates the TFSA's competitiveness by roughly 76%. Consult a licensed advisor for an approach tailored to your specific situation.

What is the 2025 TFSA contribution room?+

The 2025 TFSA annual limit is $7,000. The cumulative TFSA room for a Canadian who has been eligible since 2009 and has never contributed is $95,000 as of January 1, 2025. Your personal room depends on your contribution history and any withdrawals made (withdrawn amounts restore as room on January 1 of the following year). See CRA TFSA contributions guidance and CRA MyAccount for your specific room.

The Bottom Line

For a $90,000 Ontario earner, the RRSP versus TFSA decision has a mathematically clear answer in most scenarios: RRSP first, refund into TFSA, then max TFSA. The illustrative $49,073 advantage is real and compounds over time. It becomes a TFSA decision only when retirement income is expected to remain at or above current income levels โ€” a scenario that applies to a minority of Canadian earners. All figures are illustrative only. Consult a licensed advisor and CPA for advice based on your actual income, provincial tax rates, retirement income expectations, and account balances.
