Tax season in South Africa often feels like a burden — but with the right investment strategy, it doesn’t have to be. Whether you invest in shares, ETFs (Exchange-Traded Fund), or property, understanding how tax works on investments in South Africa can save you thousands. Better yet, using tax-efficient investment vehicles like Tax-Free Savings Accounts (TFSAs) and Retirement Annuities (RAs) can help you build long-term wealth without the tax drag.

Let’s break down the different types of taxes investors face — and show you how to reduce or avoid them.
What Taxes Do South African Investors Pay?
If you’re investing in South Africa, you may be taxed on:
- Dividends (local and foreign)
- Interest income
- Rental income
- Capital gains
- Fees and transactions
1. Dividend Withholding Tax
- Local dividends: Taxed at a flat rate of 20%, deducted before the dividend is paid to you.
- Foreign dividends: Often taxed at source (commonly 15%), and SARS may tax the remainder depending on double-taxation agreements.
2. Interest Income Tax
- Exempt amounts:
- Up to R23,800 per year (if under 65)
- Up to R34,500 per year (if 65+)
- Any interest earned above this is taxed at your marginal tax rate.
3. Rental Income
- Fully taxable as part of your income.
- Deductions allowed for expenses such as maintenance, levies, rates, insurance, etc.
4. Capital Gains Tax (CGT)
- Annual exclusion: First R40,000 of gains are tax-free.
- Only 40% of your net capital gain is added to your income and taxed at your marginal rate.
- Example: If you’re in the 45% tax bracket, your effective CGT rate is 18%.
5. Securities Transfer Tax (STT)
- 0.25% of the purchase price when you buy listed shares.
- Automatically deducted by your broker.
6. VAT on Investment Fees
- Most investment fees include 15% VAT, which is not reclaimable unless you are VAT-registered.

How to Pay Less Tax on Investments in South Africa
Now that you know what to expect, here’s how to legally reduce or avoid these taxes using tax-efficient accounts.
1. Tax-Free Savings Account (TFSA): Zero Tax, Maximum Growth
TFSAs are designed to encourage long-term saving by eliminating tax on investment returns.
TFSA Benefits:
- No tax on dividends, interest, or capital gains
- Annual contribution limit: R36,000
- Lifetime limit: R500,000
- Withdrawals allowed anytime, but they count against your lifetime limit (you cannot replace withdrawn funds)
Example: Long-Term TFSA Growth
If you:
- Contribute R36,000/year
- Reach the R500,000 limit in ~14 years
- Leave it invested for 20 years
- Earn an average of 10% return annually (4% dividends, 6% growth)
You’d end up with around R1.95 million — and save roughly:
- R60,000 in dividend tax
- R140,000 in CGT (if in the 45% bracket)
That’s over R200,000 in tax savings — simply by using a TFSA.
2. Retirement Annuity (RA): Your Long-Term Tax-Saving Hero
An RA is ideal for salary earners looking to grow retirement funds while lowering taxable income.
RA Tax Advantages:
- Deduct up to 27.5% of your taxable income (max R350,000/year)
- No tax on interest, dividends, or capital gains inside the RA
- On retirement (55+), take up to 1/3 as a lump sum (first R550,000 can be tax-free)
- The remainder must be used to purchase a living or life annuity to provide income
Example: RA Contribution Tax Benefit
If you earn R400,000 annually and contribute R60,000 to an RA:
- Taxable income drops to R340,000
- Tax payable drops from ~R69,600 to ~R54,000
- Instant tax saving of R15,600
Plus, that R60,000 grows tax-free for decades — potentially becoming R1 million+ by retirement.
3. No Extra Cash? Reallocate Smartly
Do not have spare cash for a TFSA or RA? Use this smart strategy:
- Sell investments from taxable unit trusts or share portfolios — up to R36,000/year.
- Transfer that amount into your TFSA.
- Repeat annually until your taxable portfolio is fully shifted into tax-free investments.
This strategy requires no new money — just repositioning your existing investments.

Key Tax Deadlines for South African Investors
- Tax year: 1 March – 28 February
- E-Filing opens: Every July
- Keep all tax certificates: From TFSA providers, RA administrators, and platforms like Allan Gray, 10X, or Momentum Wealth
- Always verify SARS pre-filled data: Ensure accuracy in your return
Final Tips: Make the Tax System Work for You
Paying tax is part of life — but overpaying is not. Use this priority list to minimise tax while maximising returns:
- Max out your TFSA (R36,000/year)
- Contribute to an RA (up to 27.5% of income)
- Only then, invest in taxable unit trusts, ETFs, or shares
- Use your interest exemption for emergency savings (R23,800 if under 65, R34,500 if older)
