What Is Capital Gains Tax in South Africa?

Capital Gains Tax was introduced in South Africa on 1 October 2001. Any asset acquired before this date is valued from the “valuation date” — not the original purchase price — which can significantly reduce your taxable gain on long-held assets.

CGT applies to individuals, companies, and trusts. As a South African tax resident, you are liable for CGT on assets located anywhere in the world. Non-residents are liable only on South African immovable property or assets of a permanent establishment here.

The word “dispose” is broader than most people realise. It covers not just a sale, but donations, exchanges, expropriations, death, and emigration. Understanding what triggers CGT is as important as knowing how to calculate it.

Who Pays Capital Gains Tax — and at What Rate?

How to Calculate Capital Gains Tax — Step by Step

What Counts as Base Cost?

Most taxpayers leave money behind by forgetting allowable base cost items. Every rand legitimately added to base cost reduces your gain directly. Your base cost includes all of the following:

What Are the CGT Exclusions and Exemptions for 2026?

How Does CGT Apply to Property Sales in South Africa?

Primary Residence — Zero CGT for Most Homeowners

The primary residence exclusion is the most valuable CGT benefit available to South African homeowners. To qualify, the property must be owned by a natural person (not a company or trust), and you or your spouse must ordinarily reside there as the main home. From 1 March 2026, gains up to R3,000,000 are entirely tax-free.

Investment and Rental Property

Properties that were never your primary residence receive no special exclusion beyond the standard annual exclusion. The full capital gain above R50,000 (from 1 March 2026) is subject to CGT. Many property investors are surprised by the liability when selling long-held properties in high-growth areas like Cape Town and Johannesburg.

Mixed-Use Property

If you used part of your home for business or rented it out for a period, the primary residence exclusion must be apportioned. Only the portion of the gain attributable to primary residence use qualifies for the R3,000,000 exclusion. The business or rental portion is taxed normally above the annual exclusion.

How Does CGT Apply to Shares, ETFs and Unit Trusts?

When you sell shares, ETFs, or unit trust investments for a profit, the gain is generally subject to CGT — provided you hold the investment with a long-term capital appreciation intent. Your IT3c certificate from your broker will show proceeds and base cost. Include brokerage fees, Securities Transfer Tax, and platform fees in your base cost.

Does CGT Apply to Cryptocurrency in South Africa?

All disposals of cryptocurrency are taxable events: selling for rands, swapping one coin for another, spending crypto, gifting crypto, and receiving crypto as payment. Mining rewards and staking income are taxed as ordinary income at the time of receipt.

5 Proven Strategies to Reduce Your CGT Legally

CGT is a legal obligation — but South African tax law provides legitimate tools to reduce what you pay. Here are five strategies used by experienced investors and tax practitioners:

Maximise your base cost. Every allowable cost reduces your gain directly. On a R500,000 capital gain, finding R50,000 of forgotten base costs reduces your CGT by approximately R7,800 at the 18% maximum effective rate. Keep renovation invoices, legal fee statements, and compliance certificates for the full ownership period.

Spread disposals across tax years. Sell one asset in February and the next in March — two separate tax years, two annual exclusions. At the new R50,000 rate (from 2026/27), each exclusion saves up to R9,000 in CGT at maximum effective rates.

Offset capital losses against gains. If you have loss-making investments, consider disposing of them in the same year as a large gain. The losses offset your gains rand for rand before the inclusion rate applies. Unused losses carry forward indefinitely — they are never lost.

Use spousal transfers. Transfers between spouses trigger no CGT — the gain is deferred. When the receiving spouse eventually sells, their annual exclusion also applies. A couple effectively has R100,000 in combined annual exclusions (R50,000 each from 2026/27).

Time large sales to lower-income years. If you plan to retire or take a career break, your marginal rate drops significantly. A sale planned for a high-income year versus a retirement year can save tens of thousands of rands in CGT on the same gain — because the taxable capital gain is added to your total income and taxed at whatever marginal rate results.

Common CGT Mistakes South Africans Make — and How to Avoid Them

Not declaring capital gains is the most serious mistake. SARS receives third-party data from property registries, financial institutions, and — from 2026 — crypto exchanges. Failure to declare can result in penalties of up to 200% of the underpaid tax in cases of intentional non-disclosure, plus interest.

Losing base cost records is the second most expensive error. Without invoices and receipts, SARS may disallow costs under audit — increasing your assessed capital gain. Keep all purchase documents, renovation invoices, transfer documents, and selling cost statements for at least five years after the disposal date.

Confusing repairs with capital improvements is a common mistake. Only capital improvements add to base cost — renovations, extensions, and upgrades that add value or extend the asset’s life. Routine repairs (fixing a leak, repainting, replacing broken fittings) are maintenance costs and cannot be added to base cost.

Missing the valuation date value for pre-October 2001 assets. Assets owned before 1 October 2001 can use the time-apportionment or market value method to establish a higher base cost — often significantly reducing the taxable gain. Many taxpayers miss this opportunity on long-held property.

How to Declare Capital Gains on Your SARS ITR12 Return

Capital gains do not have a separate SARS return. They are declared as part of your annual ITR12 income tax return, in the Capital Gains section. The tax year runs from 1 March to 28 February. For each asset disposed of during the tax year, you enter the date of acquisition, proceeds, base cost, and any applicable exclusions.

SARS eFiling and the SARS MobiApp both provide guided steps through the Capital Gains section. If you use a registered tax practitioner, provide them with a full asset disposal schedule including all supporting receipts and certificates well before the filing deadline.

Provisional taxpayers — those with investment income or who run their own businesses — must include estimated CGT in their IRP6 provisional tax payments (first payment in August, second in February). Underestimating provisional payments can result in a 20% underestimation penalty if your actual liability exceeds the provisional amount by more than R1,000.
