The core logic behind RRSP vs TFSA contribution priorities

A common question in retirement planning is: Should you prioritize RRSP or TFSA contributions?

There is a simple rule of thumb:

If your expected tax rate in retirement is lower than your current tax rate, prioritize RRSP. Otherwise, prioritize TFSA.


The Logic Behind This Rule

RRSP provides tax deferral, while TFSA offers tax-free growth.

RRSP works best when you contribute at a high tax rate and withdraw at a lower rate.


Why RRSP Often Has the Advantage

  • Higher current income → bigger tax deduction
  • Lower retirement income → lower tax on withdrawal
  • Long-term tax-deferred compounding

RRSP also helps enforce long-term discipline due to withdrawal restrictions.


When Funds Are Limited

If you cannot contribute to both accounts:

Step 1: Contribute to RRSP Step 2: Use the tax refund to fund your TFSA

This creates a combined tax-efficient strategy.

If your future tax rate is expected to be higher (rare case), then TFSA should be prioritized.



RRIF Withdrawal Considerations

RRSP must convert to RRIF at age 71.

Example:

  • $1,000,000 RRSP → ~5.82% withdrawal
  • Annual withdrawal ≈ $58,200

This is fully taxable income.

Many retirees start withdrawals earlier (age 60+) to reduce future tax spikes.


Liquidity in Non-Registered Accounts

Liquidity includes stocks and funds, not just cash.

You can contribute via in-kind transfer to avoid selling investments.


U.S. Investment Tax Differences

  • RRSP: 0% U.S. dividend withholding tax
  • TFSA: 15% withholding tax (non-recoverable)
  • Non-registered: 15% but recoverable via tax credit

RRSP is generally better for U.S. dividend-paying stocks.


Key Insight

RRSP vs TFSA is not about “which is better” — it’s about tax timing.

The same investment can produce very different outcomes depending on:

  • When you pay tax
  • Your income level at withdrawal
  • Your retirement strategy

Summary

In most cases, RRSP should be prioritized when your current tax rate is higher than your expected retirement tax rate.

The best strategy is often:

  • Use RRSP for tax deferral
  • Use TFSA for flexibility

  • Your current income
