Should you maximise your Tax-Free Savings Account (TFSA) contributions or take advantage of the tax benefits of a Retirement Annuity (RA)? Let’s explore the financial implications.
One key advantage of a TFSA is its flexibility in allowing investments in international markets, such as the S&P 500, which historically delivers higher returns. Retirement Annuities, on the other hand, are restricted by Regulation 28, which limits exposure to high-growth assets to reduce risk.
Investment Scenario: Comparing the Numbers
Assumptions:
• Individuals with an annual taxable income of R500,000 (36% tax bracket)
• Comparing:
o Option A: R36,000 post-tax investment in a TFSA (S&P 500 Index Fund)
o Option B: R59,016 pre-tax investment in a Regulation 28-compliant RA fund

Expected Growth Over Time (Based on Historic Averages)
• Regulation 28 RA funds: ~9% p.a.
• S&P 500 TFSA investment: ~16% p.a.


Key Takeaways
• Year 8: The TFSA fund surpasses the RA fund value.
• Year 20: The TFSA fund is R380,000 ahead of the RA fund.
• Year 30: TFSA leads by over R2 million.
• Year 40: TFSA is nearly R11.8 million higher than the RA fund.
• Tax Considerations at Retirement: Withdrawals from a TFSA are tax-free, while RA distributions may be taxable depending on your marginal income.
Final Thoughts
While RAs provide essential tax benefits and fit well within a diversified financial plan, it’s crucial to consider growth potential. If you’re looking for optimal long-term returns, a TFSA invested in high-growth international markets may be a compelling option.
