Most South Africans who have a Tax-Free Savings Account (TFSA) are doing the same thing: parking their R46,000 a year in a high growth, money market or a bland balanced fund, and moving on.
That’s not wrong. But it’s the investment equivalent of buying a Ferrari and using it to pop to Checkers.
Because here’s what most investors never ask: which assets does SARS tax the most brutally – and am I hiding those inside my TFSA?
That question is worth hundreds of thousands of rands over your investing lifetime.
Not because of better stock picks. Not because of market timing. Simply because of what you choose to own inside the one account where SARS has absolutely no jurisdiction.
Think of your TFSA as prime real estate with a lifetime cap of R500,000. Every rand of that space is precious. Fill it with assets that barely generate taxable income, and you’ve wasted the shelter on something that didn’t need protecting.
Fill it with assets that SARS would otherwise carve up every single year – and suddenly you’re compounding wealth that was never yours to lose in the first place.
That’s the move. And today, I’m going to show you exactly how to make it.
Meet SARS’ two biggest meals…
Before we get to the solution, you need to understand exactly what you’re protecting yourself from.
Meal one: Income tax on interest
If you earn interest – from bonds, fixed deposits, money market funds – that income is added to your salary and taxed at your marginal rate.
Earn over R512,800 a year? You’re paying 36% on every rand of interest. Earn more? It goes to 39%, 41%, even 45%. The annual interest exemption (R23,800 if you’re under 65) gets chewed up faster than you think.
Meal two: Income tax on REIT distributions
This one surprises people. REITs – listed property funds – are required by law to distribute 75% of their income to investors. And in South Africa, those distributions are taxed as income, not as dividends. That means your marginal rate again. Up to 45%. On a high-yielding income asset. Ouch.
The move that supercharges your income
Your TFSA should be home to your highest-yielding, most heavily-taxed assets. Not your growth stocks. Not your global index trackers that barely pay a dividend. Those are fine investments – but they’re not where the TFSA earns its keep.
The assets that belong in your TFSA are bonds and listed property (REITs).
Let’s make this concrete.
Bonds: Turning your biggest tax liability into your biggest win
A bond ETF yielding 9% a year is, outside a TFSA, a tax problem for any investor in the 36% bracket or higher.
On R46,000 invested, every year:
That R1,490 sounds modest. Until you compound it.
Reinvest that annual tax saving at 9% over 15 years and it quietly grows into an extra R44,000 in your pocket. From the same investment. Just by keeping it in the right account.
REITs: The property powerhouse that SARS loves to tax
Listed property funds – REITs – are among the most income-generous assets available to South African investors. Yields of 6–8% are common.
They’re legally required to distribute the bulk of their income.
But outside a TFSA, those distributions are taxed as income at your marginal rate. For a 36% taxpayer, you’re handing more than a third of your property income straight to SARS, every year, automatically.
On R46,000 in a REIT ETF yielding 6%, every year:
That’s nearly R1,000 extra in your pocket every single year – without taking on more risk or picking a better investment.
Stretch that over 15 years, reinvest the difference, and it compounds into roughly R29,000 in additional wealth from this contribution alone.
The 15-Year Picture: What “Doing It Right” Actually Looks Like
Let’s compare two investors.
Both invest R46,000 a year, earn an 8% annual return, and sit in the 36% tax bracket.
The only difference?
• One uses a TFSA (and stops once the R500,000 lifetime limit is reached).
• The other invests the same R500,000 total in a taxable account.
So, this is a true like-for-like comparison.
That R280,000 gap isn’t from better stock picks. It isn’t from timing the market. It’s from structure – putting the most tax-exposed assets in the one account where tax doesn’t exist.
Remember: This is not a savings account. Do not use it like one. Every rand that enters your TFSA should be money you intend to leave there for 20, even 30 years.
The magic of this account is compounding without tax drag. Disrupt that compounding and you’ve wasted the most valuable thing the TFSA offers: time.
