I'm asked this question by clients almost every week: "Should I put my extra savings in my RRSP or my TFSA?" The answer depends on one key factor — your marginal tax rate today compared to your expected tax rate in retirement.
RRSP 與 TFSA 的核心區別
Contributions reduce your taxable income now. But every dollar you withdraw in retirement is fully taxed as income.
No deduction now, but every dollar you withdraw — including all growth — is completely tax-free, forever.
Both accounts grow tax-sheltered while your money is inside them. The key difference is when tax is applied: RRSP users pay tax on the way out; TFSA users have no tax on the way out at all.
RRSP 勝出的情況
- Your current income is high (above $80,000–$100,000) and you expect a significantly lower income in retirement
- You want the tax refund now and plan to reinvest it immediately
- Your RRSP is far from fully funded and you're in your peak earning years
- You have a pension that will provide significant income in retirement — the RRSP tax deduction offsets your high current rate
Example: A $25,000 RRSP contribution in a 46% tax bracket saves you $11,500 in taxes this year. Invest that refund back in your TFSA and you've effectively turbocharged both accounts simultaneously.
TFSA 勝出的情況
- Your income is moderate (below $60,000) and the RRSP deduction won't save you much tax
- You expect your income in retirement to be similar to or higher than today
- You want flexibility — TFSA withdrawals don't affect OAS, GIS, or government benefit calculations
- You're saving for a medium-term goal (10–20 years) that isn't strictly for retirement
- Your RRSP is already well-funded and the marginal value of more RRSP room is diminishing
兩者兼顧的理由
In most cases, Carrie recommends filling both accounts — in a ratio that reflects your income. The RRSP gets your money first (capturing the deduction), and the tax refund flows directly into your TFSA. This 'RRSP refund re-contribution' strategy is one of the most powerful ways to maximize both accounts simultaneously.
The RRSP refund strategy
Contribute $15,000 to your RRSP. At a 43% marginal rate, you receive a $6,450 tax refund. Deposit that refund directly into your TFSA. You've effectively sheltered $21,450 total — $15,000 tax-deferred and $6,450 tax-free — from a single $15,000 out-of-pocket investment.
收入水平如何影響決策
| 家庭收入 | RRSP 優先度 | TFSA 優先度 | 建議分配 |
|---|---|---|---|
| Under $50,000 | Low | High | 主要 TFSA |
| $50,000–$80,000 | Medium | Medium | 平均分配 |
| $80,000–$120,000 | High | Medium | 主要 RRSP + 退稅至 TFSA |
| Over $120,000 | Very high | Medium | 先最大化 RRSP,再 TFSA |
Carrie's simple rule: If your income is high today and you expect it to be lower in retirement — prioritize RRSP. If you're unsure — do both and put the RRSP refund into your TFSA. This is almost always a winning strategy regardless of your future tax situation.
