What is Capital Gains Tax (CGT) in South Africa?
Capital Gains Tax (CGT) is not a separate tax in South Africa. It forms part of the normal income tax system. When you dispose of an asset (like property, shares, or a business) for more than its base cost, you make a capital gain. A portion of this gain is included in your taxable income for the year and taxed. For individuals, it's taxed at your marginal income tax rate. For companies and trusts, it's taxed at the corporate tax rate. The system provides specific exclusions to reduce the tax burden, particularly for individuals and primary residences.
How is Capital Gains Tax Calculated?
The calculation follows a defined process:
- Determine the Capital Gain: This is the selling price, minus the original cost of the asset and any allowable expenses incurred in buying or selling it.
- Apply Exclusions (for individuals only):
- Annual Exclusion: The first R40,000 of a net capital gain in a tax year is exempt.
- Primary Residence Exclusion: For a property that was your main home, the first R2 million of the capital gain is exempt.
- Special Death Exclusion: An additional R300,000 exclusion applies to the net capital gain of a deceased person in the year of death.
- Calculate the Net Capital Gain: This is the gain remaining after all applicable exclusions.
- Apply the Inclusion Rate: Only a percentage of the net capital gain is added to your income. For individuals, it's 40%. For companies and trusts, it's 80%.
- Calculate the Taxable Capital Gain: This is the amount (inclusion rate * net capital gain) that is subject to tax.
- Apply the Correct Tax Rate:
- For Individuals: The taxable capital gain is added to your other annual taxable income. The total income determines your highest tax bracket (marginal tax rate). The tax on the taxable capital gain is calculated at this marginal rate.
- For Companies and Trusts: The taxable capital gain is taxed directly at the corporate tax rate (27% for the 2026 tax year). Other income is not required for this calculation.
Calculation Example for a Company
Let's say a company sells a commercial property for R5,000,000. The original purchase price was R2,000,000 and selling expenses were R200,000.
- Capital Gain: R5,000,000 - R2,000,000 - R200,000 = R2,800,000
- Exclusions: None apply to companies.
- Net Capital Gain: R2,800,000
- Inclusion (80%): R2,800,000 * 80% = R2,240,000 (This is the taxable capital gain)
- Corporate Tax Rate (2026): 27%
- CGT Liability: R2,240,000 * 27% = R604,800
- Effective Rate on Gain: R604,800 / R2,800,000 ≈ 21.6%
Frequent Scenarios
- Selling Your Home: The primary residence exclusion of R2 million makes CGT negligible for most homeowners unless the gain is extremely large.
- Selling Shares: The same rules apply. Keep records of purchase prices and brokerage fees.
- Inherited Assets: The base cost for the heir is generally the market value at the date of death. CGT may apply when the heir later sells the asset.
- Gifts (Donations): Donating an asset is considered a disposal at market value, potentially triggering CGT for the donor.
Next Steps and Documents
After estimating your CGT liability, you should declare the capital gain in your annual income tax return (ITR12 for individuals, IT14 for companies). If you are in the process of selling an asset, having a clear legal agreement is crucial. For property sales, a Deed of Sale for Fixed Property outlines all terms. For share sales, use a Sale of Shares Agreement. If you are gifting an asset, a Deed of Donation is necessary to formalize the transfer and document the market value for tax purposes.
