Capital Gains Tax in South Africa: What Retirees and Investors Actually Pay (2026)

Capital gains tax in South Africa is a tax on the profit you make when you sell or dispose of an asset. It’s calculated on the net gain, the sale price minus your original cost and allowable expenses, not on the full proceeds.

Here’s what most investors get wrong: the effective maximum rate for individuals in 2026 is 18%, not the flat 10% that circulates widely. That 10% is a shorthand that only holds at certain income levels. Once your income climbs, so does the rate. Every individual also receives an R40,000 annual exclusion, which means the first R40,000 of net capital gains in any tax year is simply ignored.

If you hold your savings inside a retirement annuity or living annuity, capital gains tax doesn’t apply inside the fund at all. This is one of the most valuable and least understood advantages of retirement fund wrappers, and it matters enormously when you’re deciding where to hold longer-term investments. You can read more about the interaction between tax-free savings accounts and retirement annuities in a separate article.

This article walks through how CGT is calculated, which assets it applies to, and where retirement planning decisions genuinely change your exposure. For a broader view of how tax sits inside your retirement plan, the guide on retirement planning financial advice is a good companion.

This is general information, not personal financial advice.

What Is the Current Capital Gains Tax Rate in South Africa?

Capital gains tax in South Africa is not a separate flat tax. It works by including a portion of your capital gain in your taxable income, then taxing that combined amount at your marginal income tax rate.

For individuals, the inclusion rate is 40%. Take 40% of your net capital gain and add it to your other income. Tax the combined total at whatever rate applies to that income level. At the highest marginal income tax rate of 45%, the effective maximum CGT rate works out to 40% × 45% = 18%. At the 26% bracket, it’s roughly 10.4%.

This is why the flat-10% myth persists. It’s a reasonable approximation at lower income levels, but it seriously underestimates the liability for someone drawing significant income from other sources alongside a capital event, exactly the position many retirees and business owners find themselves in.

A Worked Example

You sell an investment property and generate a net capital gain of R500,000. After deducting the R40,000 annual exclusion, your taxable gain is R460,000.

Apply the 40% inclusion rate: R460,000 × 40% = R184,000 is added to your other income for the year.

If your total income, including that R184,000, falls into the 45% bracket, you pay tax of R82,800 on the capital gain component. As a percentage of the original R500,000 gain, that’s 16.6%, close to but not quite at the 18% ceiling.

If your total income sits in the 36% bracket instead, the tax on that R184,000 becomes R66,240, an effective rate of roughly 13.2% on the gain.

The practical lesson: your CGT liability is inseparable from your other income in the same year. Timing the disposal of an asset, and planning around your income in that specific year, can make a material difference. The South Africa Budget 2026 and its impact on investors article covers any recent changes.

CGT Rates at a Glance: Individuals, Companies and Trusts

The rate you pay depends on the type of entity that owns the asset. Here’s a clear comparison:

Two points from this table deserve emphasis. First, holding a capital asset inside a discretionary (non-special) trust carries a significantly higher effective CGT rate than holding it in your own name. Second, companies face an 80% inclusion rate, which often makes them less efficient than individuals for holding appreciating assets, depending on the full picture.

There are two further concessions worth knowing. On death, the first R300,000 of a capital gain is excluded in addition to the standard annual exclusion, which provides some relief to estates. And where assets pass between spouses, a rollover applies: no CGT is triggered at transfer, and the receiving spouse simply inherits the original cost base.

How Is Capital Gains Tax Calculated on Property Sales?

For property sales, CGT applies to the net gain: the sale price minus the original purchase price, the cost of improvements, and legitimate selling costs such as agent commissions. You don’t pay tax on the full sale proceeds.

For your primary residence, a substantial exclusion applies. The first R2 million of a capital gain on a primary residence is excluded from CGT. Beyond that threshold, the normal inclusion rate and marginal rate apply.

The Six-Year Rule Explained

Many investors ask about the “six-year rule.” This is an absence concession, not a blanket exemption. If you’re temporarily absent from your primary residence, for example because you work abroad, and you don’t acquire a new primary residence elsewhere, you can maintain the primary residence designation for up to six consecutive years of absence.

The confusion is understandable. Some investors apply this rule to investment properties or assume it creates a six-year window to sell any property tax-free. It does neither. It’s narrowly aimed at preventing people from losing their primary residence exclusion solely because of temporary work-related absence.

A Worked Example for an Investment Property

You purchase a second property for R3 million. You sell it ten years later for R5 million. You’ve spent R200,000 on approved improvements, and you pay R150,000 in agent fees. Your base cost is therefore R3,350,000.

Net gain: R5,000,000 minus R3,350,000 = R1,650,000. Less the R40,000 annual exclusion: R1,610,000. Apply the 40% inclusion rate: R644,000 is added to your taxable income.

At a 45% marginal rate, the tax on the gain is R289,800, an effective rate of approximately 17.6% on the original R1,650,000 gain.

That’s a significant liability, and it underlines why the timing of property disposals matters. For property held offshore, additional complexities apply; the offshore property and investment CGT considerations for South African retirees article covers those.

How Does Capital Gains Tax Apply to Shares and Unit Trusts?

Shares and unit trusts are subject to CGT in largely the same way as property. When you sell shares or switch between unit trust funds, you trigger a CGT event. The net gain, after deducting your base cost and the annual exclusion, is included in taxable income at the 40% inclusion rate.

A common misconception is that unit trusts are taxed differently from other investments. They’re not, as far as CGT on your own disposal is concerned. When you switch between portfolios within a unit trust platform, SARS treats it as a disposal of the old units and an acquisition of the new ones. That switch can trigger CGT even if no cash leaves the platform.

Two CGT Events in a Unit Trust

There are actually two possible CGT events to track:

1. Capital gain distributions by the fund. Some unit trust funds distribute realised capital gains to investors as part of their annual distribution. When this happens, 40% of that distribution is included in your taxable income for the year, even if you reinvested the distribution and received no cash.

2. Your own disposal or switch. When you sell units or switch to a different fund, any gain on the units you held is a CGT event at investor level.

Both events use the same annual exclusion, which is shared across all your capital gains in a tax year, not applied separately to each asset.

Tax-Free Wrappers

Hold unit trusts inside a tax-free savings account (TFSA) and no CGT applies on growth or on switches within the account. This is one of the TFSA’s most valuable features for long-term investors. The article on how a tax-free savings account compares to a retirement annuity for tax-efficient growth covers this in detail.

If you hold gold, gold ETFs, or other commodity-linked instruments, the CGT implications of gold investments in South Africa article is worth reading alongside this one.

What Tax Implications Do Retirement Annuities and Living Annuities Have?

Retirement annuities and living annuities do not attract capital gains tax inside the fund. This is one of the most practically significant tax advantages available to South African investors, and it’s frequently underestimated.

During the Saving Phase

Inside a retirement annuity (RA), the underlying assets, equities, bonds, property funds, can be bought, sold, and switched without triggering CGT. The fund itself is not a CGT taxpayer in that way. This means decades of compounding aren’t eroded by CGT events along the way, which is a material advantage over holding the same assets in your own name.

Your contributions to an RA are also tax-deductible, up to the limits set by SARS. The retirement annuity contribution limits and deductions article covers those numbers.

At Retirement

When you retire from an RA or any other retirement fund, the lump sum you take is not subject to CGT. It’s taxed under the retirement lump sum tax table instead, which uses a different set of rates and thresholds. For the tax treatment of lump sums, the how retirement annuities are taxed in South Africa article explains the mechanics.

The income you draw from a living annuity is taxed as ordinary income, not as a capital gain. The capital held inside the living annuity continues to grow free of CGT for as long as it remains invested.

Contrast with Own-Name Investments

Hold the same assets in a discretionary investment account in your own name, and every switch, sale, or rebalancing event potentially triggers CGT. Over a long accumulation period, the difference in after-tax compounding between a retirement fund wrapper and an own-name investment can be very significant. The income choices for South African retirees article looks at how these wrappers sit alongside each other in a retirement income plan.

Selling a Business: How CGT Works on a Large Capital Event

Selling a business is typically the largest single capital event most investors will ever face, and it concentrates CGT exposure in a single tax year in a way that few other transactions do.

When you sell a business as a going concern, the proceeds attributable to goodwill, intellectual property, and other capital assets are subject to CGT. The sale of shares in an operating company also triggers CGT at shareholder level on the gain over the original base cost of the shares.

A Worked Example at R10 Million

You sell your business and realise a net capital gain of R10 million, after deducting your base cost and all legitimate selling expenses. After the R40,000 annual exclusion, the taxable gain is R9,960,000.

Apply the 40% inclusion rate: R3,984,000 is added to your taxable income for that year.

At the 45% marginal rate, the CGT liability on that amount is R1,792,800. That’s roughly 18% of the original R10 million gain.

Small Business Exclusion

SARS provides a small business exclusion for qualifying businesses sold by individuals who are 55 or older, or who sell due to ill health or other qualifying circumstances. The thresholds and conditions are specific. Verify the current figures directly with SARS or your tax adviser, as they’re adjusted over time and eligibility depends on the nature of the business and the structure of the transaction.

Why Structure Matters

The structure of a business sale, whether you sell assets or shares, whether proceeds flow to you personally or into a trust, and how you deploy the capital afterwards, can all affect the total tax outcome significantly. This is a decision that requires specialist tax and financial planning input before any agreement is signed, not after.

If you’re reinvesting business sale proceeds, the article on how to invest R10 million in proceeds from a business sale offshore is relevant, as is the guide on managing retirement funds after a business sale before age 61.

How to Reduce Your CGT Liability Legally and Effectively

Reducing your CGT liability comes down to using the wrappers, exclusions, and timing tools that South African tax law already provides. Five practical strategies are worth understanding.

1. Use retirement fund wrappers. Retirement annuities, preservation funds, and provident funds do not attract CGT on internal growth. Maximising your annual RA deduction, which you can compare against your provident fund in the comparing retirement annuities and provident funds for tax efficiency article, keeps more growth inside a CGT-free environment.

2. Use your tax-free savings account. Growth, switches, and income inside a TFSA are CGT-free for life. The choosing between a tax-free savings account and a retirement annuity article helps you decide which wrapper to prioritise.

3. Time disposals deliberately. Because CGT liability depends on your total income in the year of disposal, selling in a year when your other income is lower, for example, in the year after retirement when salary has stopped, can reduce the marginal rate that applies to the gain.

4. Use the annual exclusion consistently. The R40,000 annual exclusion is a use-it-or-lose-it concession. Realising gains strategically each year, up to the exclusion level, can reduce the cumulative gain on a large asset over time.

5. Consider Shari’ah-compliant structures. Shari’ah-compliant retirement annuities, unit trusts, and offshore funds operate within the same CGT framework as conventional products. The tax treatment is identical, so you don’t sacrifice any CGT efficiency by investing in Shari’ah-compliant structures. The Shari’ah-compliant investing and tax-efficient strategies article covers the product landscape.

This is general information, not personal financial advice. The right combination of strategies depends on your full financial picture and should be discussed with a CFP professional.

Frequently Asked Questions About Capital Gains Tax in South Africa

Is the capital gains tax rate 10%?

No. The 10% figure is a rough approximation that only holds at lower marginal income tax rates. For individuals, the effective maximum CGT rate is 18% (40% inclusion rate applied to a 45% marginal rate). Your actual rate depends on your total income in the year of disposal.

What is the basic definition of a capital gain?

A capital gain is the profit you make when you sell or dispose of a capital asset for more than you paid for it. The gain is calculated as the proceeds minus the base cost (original purchase price plus allowable improvements and acquisition costs), not on the full sale price.

What is the six-year rule in relation to capital gains tax?

The six-year rule is an absence concession for primary residences only. It allows you to maintain your primary residence designation for CGT purposes during a temporary absence of up to six consecutive years, provided you don’t acquire another primary residence. It doesn’t exempt all property from CGT and doesn’t apply to investment properties.

What is the current capital gains tax rate in South Africa?

In 2026, individuals face a 40% inclusion rate and a maximum marginal income tax rate of 45%, giving an effective maximum CGT rate of 18%. Companies face a 22.4% effective rate. Non-special trusts face an effective maximum of 36%.

How is capital gains tax calculated on property sales?

CGT on a property sale is calculated on the net gain: sale proceeds minus the base cost (original purchase price, approved improvements, and allowable selling expenses). After deducting the R40,000 annual exclusion, 40% of the remaining gain is added to your taxable income and taxed at your marginal rate.

Is capital gains tax applied to primary residences?

Yes, but with a significant exclusion. The first R2 million of a capital gain on your primary residence is excluded from CGT. Any gain above R2 million is subject to the standard CGT calculation.

How does capital gains tax apply to share transactions for individual investors?

When you sell shares at a profit, the net gain (after deducting the annual exclusion) is included at 40% in your taxable income. If SARS treats you as a trader rather than an investor, the full profit may be taxed as ordinary income without the inclusion rate benefit. The classification depends on the nature and frequency of your trading activity.

What is the annual exclusion amount for capital gains tax?

The annual exclusion for individuals and special trusts is R40,000 per tax year. It applies across all capital gains and losses in the year. On death, an additional R300,000 exclusion applies on top of the standard annual exclusion.

How is capital gains tax handled for second properties?

Second properties receive no primary residence exclusion. The full net gain (sale price minus base cost and selling costs, less the R40,000 annual exclusion) is subject to the standard 40% inclusion rate and your marginal income tax rate. If you need to know about CGT implications for South Africans moving abroad, that article addresses cross-border property situations.

How are unit trusts taxed in South Africa?

Unit trust investors face CGT when they sell or switch units (at investor level) and when the fund distributes realised capital gains (at distribution level). Both events use the 40% inclusion rate and your marginal income tax rate. Holding unit trusts inside a TFSA eliminates CGT entirely on those holdings.

The Bottom Line on Capital Gains Tax for South African Investors

Capital gains tax in South Africa is a real cost, but it’s manageable if you understand how it works and plan around it deliberately.

Three points are worth holding onto. First, the rate isn’t flat: your effective CGT rate depends on your marginal income tax rate in the year of disposal, and proper timing can make a meaningful difference. Second, retirement fund wrappers, including retirement annuities and living annuities, don’t attract CGT inside the fund, making them one of the most tax-efficient vehicles available to South African investors over a long accumulation period. Third, the annual exclusion, the primary residence exclusion, and the death exclusion all reduce your liability in predictable, structured ways, and using them systematically is more effective than trying to avoid CGT reactively.

The decisions that matter most tend to cut across several assets at once: the order in which you retire from different funds, the year in which you sell a property or a business, and how you allocate between retirement fund wrappers and own-name investments. No single asset-level decision can substitute for a cross-asset plan.

The guide on retirement planning financial advice for South Africans is a good next step if you want to see how CGT fits into a broader retirement income plan. The offshore investing guide for South African retirees covers the CGT dimension of holding assets abroad.
