Capital Gains Tax on Selling Property in South Africa
How CGT works when you sell a home or investment property in South Africa — R3 million primary residence exclusion from 1 March 2026, annual exclusion, timing rules, and home-office taint.
Capital Gains Tax on Selling Property in South Africa
Selling a home or investment property can trigger Capital Gains Tax (CGT) even when no salary income changed. For disposals linked to 1 March 2026 and later, Budget 2026 increased the primary residence exclusion to R3 million (was R2 million) and the annual exclusion for individuals to R50 000 (was R40 000). Timing and “primary residence” rules decide how much relief you get.
Informational only — verify your disposal date, base cost, and calculations with SARS or a registered tax practitioner.
When Does CGT Arise?
CGT generally applies when you dispose of an asset — commonly when the sale agreement is concluded (or suspensive conditions are fulfilled), not when the deed registers at the Deeds Office. A deal signed in late February 2026 can fall under older exclusion amounts even if transfer only happens months later. Always map the legal disposal date before you pick R2m vs R3m relief.
Primary Residence Exclusion
If the property qualifies as your primary residence, you may disregard a portion of the capital gain:
| Rule theme | Amount |
|---|---|
| From disposals on/after 1 March 2026 (typical Budget 2026 position) | R3 000 000 |
| Earlier disposals (historical) | R2 000 000 |
Only one property at a time generally qualifies. Land used mainly for domestic purposes is typically limited (often discussed as up to two hectares). Gains above the exclusion remain in the CGT calculation.
Annual Exclusion
Natural persons also get an annual CGT exclusion — commonly R50 000 from the Budget 2026 update (was R40 000). This applies across your capital gains/losses for the year of assessment, not only property.
Base Cost and Improvements
Proceeds minus base cost (and allowable expenditure) drive the gain. Base cost themes often include purchase price, certain transfer costs, and qualifying capital improvements — keep invoices and transfer documents. Do not invent “percentage of municipal value” shortcuts unless they match SARS rules for your facts.
Home Office “Taint”
Using part of your home as a qualifying home office can taint a portion of the primary residence exclusion for the area/period used for trade. See our Home Office Tax Deductions guide before claiming office expenses — the refund today can affect CGT later.
Investment / Second Properties
Properties that are not your primary residence generally do not get the R3m primary residence exclusion. Annual exclusion may still apply. Non-resident withholding tax on property disposals is a separate topic for non-residents.
Effective Rate Theme
For individuals, a portion of the net capital gain is included in taxable income (commonly 40% inclusion). At a top marginal rate of 45%, the oft-quoted maximum effective CGT rate is about 18%. Your actual rate depends on your taxable income band.
Filing Season Checklist
- Confirm disposal date vs 1 March 2026.
- Establish whether primary residence rules apply.
- Rebuild base cost with documents.
- Consider home-office apportionment if relevant.
- Declare the gain on your ITR12 — property sales are easy for auto-assessments to miss if third parties have not reported them.
How Refund AI Can Help
Refund AI can help you research CGT concepts, exclusion themes, and what questions to verify with SARS. It does not calculate your gain or file returns. Confirm figures with primary sources or a practitioner.
Conclusion
Property CGT is mostly about timing, primary residence status, and records. Use the R3 million / R50 000 Budget 2026 themes only when they apply to your disposal, and link any home-office history into the calculation thoughtfully.
