Capital Gains Tax on Property: Your Primary Home vs a Second Property
By Wallett & Finch Properties | Updated October 2026
Selling a property is a significant financial decision. Alongside the selling price and transaction costs, it helps to understand how capital gains tax could affect the amount you keep.
For Cape Town homeowners, the distinction between a primary residence and a second property can make a substantial difference. Here is a practical guide for individuals selling property held as a capital investment.
What is capital gains tax?
Capital gains tax, or CGT, forms part of your income tax. It applies to a capital gain when you dispose of an asset, including property.
The starting calculation is:
Capital gain = sale proceeds − qualifying base cost
Your base cost can include the purchase price, qualifying acquisition and disposal expenses such as transfer duty, conveyancing fees and estate agent commission, and qualifying capital improvements still reflected in the property when sold.
Routine maintenance, rates, insurance and bond interest generally do not form part of a residential property's base cost. Keep invoices and supporting records: an expense needs to qualify, rather than simply have been money spent on the home.
Selling your primary residence
Your primary residence is generally the home you ordinarily live in and use mainly for domestic purposes.
SARS currently lists a R3 million primary-residence exclusion. Subject to the qualifying rules, the first R3 million of the capital gain on your home is excluded.
This is an exclusion from the gain—not a R3 million limit on the selling price.
A qualifying home sold for R6 million with a base cost of R3.5 million produces a R2.5 million gain. If the full gain qualifies, the primary-residence exclusion covers it.
Joint owners share the residence exclusion according to their ownership interests; each owner does not receive a separate R3 million exclusion on the same home.
Selling a second property
A holiday apartment, buy-to-let property or additional home that does not qualify as your primary residence generally does not receive the R3 million residence exclusion.
Individuals currently receive a R50,000 annual capital-gains exclusion. This applies across their capital gains and losses for the tax year, rather than separately to every property.
After applicable exclusions and capital losses, 40% of an individual's net capital gain is included in taxable income. That amount is taxed under the normal income-tax rules.
The maximum effective CGT rate for individuals is 18%, derived from a 40% inclusion rate and the top 45% income-tax rate. Your actual tax depends on your total taxable income.
A worked comparison
Assume one individual sells a property for R6 million with a qualifying base cost of R2 million. The gain is R4 million.
| Calculation | Fully qualifying primary residence | Second property |
| Capital gain | R4,000,000 | R4,000,000 |
| Primary-residence exclusion | R3,000,000 | None |
| Remaining gain | R1,000,000 | R4,000,000 |
| Annual exclusion | R50,000 | R50,000 |
| Net capital gain | R950,000 | R3,950,000 |
| Amount included in taxable income at 40% | R380,000 | R1,580,000 |
| Illustrative additional tax if all this income falls in the 45% bracket | R171,000 | R711,000 |
These examples assume no other capital gains or losses, an unused annual exclusion and full qualification for the residence exclusion where applicable. The final row is a top-bracket illustration, not a fixed tax rate for every seller.
What if you rented out your home?
A property can have a mixed history: your home for several years, then a rental, or a residence with part used for business.
In these cases, the gain may need to be apportioned between qualifying residential use and non qualifying periods or portions. Moving into an investment property shortly before selling does not automatically make its entire gain exempt. Specific temporary-absence concessions may apply.
Ownership also matters. A company or ordinary trust generally cannot claim the primary-residence exclusion simply because its shareholder or beneficiary lives in the property.
Plan before you sell
Before accepting an offer:
- Gather purchase documents, improvement invoices and selling-cost estimates.
- Record when you occupied, rented out or used the property for business.
- Ask your tax practitioner to estimate the tax and confirm the applicable disposal date and tax year.
- Budget using expected net proceeds after selling costs, any bond settlement and tax.
Properties acquired before 1 October 2001 require special base-cost treatment. Property trading can also produce income-tax consequences different from the CGT treatment described here.
