Capital gains tax (CGT) is triggered every time you sell a South African investment property for more than you paid. It is not a separate tax — it is included in your income tax assessment — but it can be substantial on a profitable property sale. Understanding how it works is essential before any disposal.

How CGT Works on Property in SA

The capital gain is calculated as: sale price minus base cost minus selling costs. The base cost includes the original purchase price plus all capital improvements. Selling costs (agent commission, attorney fees) are deductible. The resulting net capital gain is then reduced by the annual exclusion (R40,000 for natural persons) and multiplied by the inclusion rate before being added to your taxable income.

CGT Inclusion Rates 2025/2026

Natural persons: 40% inclusion rate. This means 40% of your capital gain is added to your taxable income and taxed at your marginal rate. At the top marginal rate of 45%, the maximum effective CGT rate is 18% (40% × 45%).

Companies and close corporations: 80% inclusion rate. At the flat company tax rate of 27%, the effective CGT rate is 21.6% (80% × 27%).

Trusts: 80% inclusion rate. At the trust tax rate of 45%, the effective CGT rate is 36%. Trusts are the most tax-inefficient vehicle for CGT purposes.

Primary Residence Exclusion

If you sell your primary residence, the first R2 million of capital gain is excluded from CGT. This is one of the most valuable tax reliefs available to South African property owners. If your home has increased in value by less than R2 million, there is no CGT to pay on the sale.

Investment property note: The primary residence exclusion only applies to property that is your main home. It does not apply to buy-to-let investment properties, holiday homes, or properties held in a company or trust.

Strategies to Minimise CGT Legally

Document all capital improvements — they increase your base cost and reduce your gain. Hold property for long periods — the annual exclusion of R40,000 per year becomes more valuable over time on a per-year-held basis. Consider the timing of disposal — selling in a lower-income year reduces your marginal rate. Use the primary residence exclusion if you genuinely live in the property. Consult a tax practitioner before selling — there may be rollover relief or other provisions that apply to your specific situation.
