The South Africa Capital Gains Tax (CGT) calculator helps individuals and companies estimate the tax payable on the disposal of assets such as property, shares, unit trusts, and other investments. CGT in South Africa is not a standalone tax — it is integrated into the income tax system through an inclusion rate mechanism. When an asset is sold, the capital gain (proceeds minus base cost minus allowable deductions) is calculated. A specified percentage of this gain — the inclusion rate — is then added to taxable income and taxed at the taxpayer's applicable marginal income tax rate. For individuals, the inclusion rate is 40%, meaning only 40% of a capital gain is included in taxable income. Combined with the maximum 45% income tax rate, the maximum effective CGT rate for individuals is 18% (40% × 45%). Companies include 80% of capital gains, giving an effective rate of 22.4% (80% × 28% corporate tax rate). Importantly, individuals receive an annual exclusion of R40,000 — the first R40,000 of net capital gains per year is completely exempt. On death, a larger exclusion of R300,000 applies. The primary residence exclusion exempts the first R2,000,000 of capital gain on the sale of a primary home from CGT. South Africa also applies CGT on a deemed disposal basis when individuals become non-resident.
Capital Gain = Proceeds - Base Cost - Allowable Costs; Net Capital Gain = Capital Gain - Annual Exclusion (R40,000 individual); Inclusion Amount = Net Capital Gain × 40% (individual) or × 80% (company); Tax = Inclusion Amount × Marginal Tax Rate
- 1Calculate the capital gain: gross proceeds minus base cost (purchase price + acquisition costs + capital improvements) minus disposal costs.
- 2Subtract the annual exclusion of R40,000 (individual) to arrive at the net capital gain.
- 3Apply the inclusion rate: 40% for individuals, 80% for companies.
- 4Add the inclusion amount to taxable income for the year.
- 5Apply the marginal income tax rate to determine the CGT component of income tax.
- 6For primary residence: apply R2M exclusion before the annual exclusion.
- 7Check time-apportionment rules if the asset was held before October 2001 (CGT introduction date).
Maximum individual effective CGT rate is 18%
After the R40,000 exclusion, 40% of the R760,000 net gain (R304,000) is added to income. At 45% marginal rate, CGT is R136,800. The effective rate of 17.1% is far below the 45% income tax rate.
First R2M of primary home gain exempt
The R2M primary residence exclusion shelters most of the gain. Only R960K after exclusions enters the inclusion calculation. Without the primary home exclusion, CGT would be far higher.
Lower marginal rate means much lower effective CGT
At 31% marginal rate, the effective CGT rate is only 9.1% — not the feared high rate. The inclusion mechanism and progressive rates make CGT very manageable for moderate income earners.
Companies use 80% inclusion rate, no annual exclusion
Companies face a higher inclusion rate (80%) but no annual exclusion. At 28% corporate tax rate, the effective CGT rate is 22.4% — higher than individuals at lower marginal rates.

What is the annual CGT exclusion for individuals?
R40,000 per year. The first R40,000 of net capital gains is completely exempt. This exclusion cannot be carried forward to future years. This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the primary residence exclusion?
The first R2,000,000 of capital gain on the disposal of a primary residence is excluded from CGT. If the home was not the primary residence for the entire period, a time-apportionment reduces the exclusion. This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the inclusion rate for individuals?
40% for individuals. This means 40 cents of every rand of net capital gain is added to taxable income. The maximum effective individual CGT rate is 18% (40% × 45%). This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Are shares subject to CGT?
Yes. Profits from selling listed shares, unit trusts, ETFs, and unlisted shares are subject to CGT. Dividends are separately subject to Dividends Tax at 20%. This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the death exclusion?
On death, a person is deemed to have disposed of all assets. The exclusion on death is R300,000 (instead of the normal R40,000 annual exclusion), plus the primary residence exclusion still applies. This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
When did CGT start in South Africa?
CGT was introduced on 1 October 2001. Assets held before that date have their gain time-apportioned — only the portion of gain accruing after October 2001 is subject to CGT. This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Is CGT payable on cryptocurrency?
Yes. SARS treats cryptocurrency as an asset for CGT purposes. Profits from buying and selling cryptocurrency are subject to CGT (or income tax if trading is the primary business activity). This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can capital losses be offset against gains?
Yes. Capital losses can be set off against capital gains in the same year. Excess losses carry forward to future years. Losses cannot be set off against ordinary income. This is particularly important in the context of sa cgt calculatorulator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise sa cgt calculatorulator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Pro Tip
Keep meticulous records of all capital expenditure on investment assets — purchase price, transfer costs, renovation costs, legal fees, and agent commissions all form part of your base cost and reduce your eventual capital gain. Missing expenditure records can significantly overstate taxable gains when you eventually sell.
Did you know?
South Africa introduced CGT on 1 October 2001 — relatively late compared to most developed countries. Initially the inclusion rate for individuals was just 25% (giving an effective rate of around 10% at the top). It was raised to 33.3% in 2012 and to 40% in 2016. Despite these increases, South Africa's effective CGT rate for individuals remains among the lower half of OECD-comparable economies, partly because the progressive income tax already captures most high-income earners.
