Capital Gains Tax in South Africa: How It Works and How to Reduce It

You sell a flat, some shares or a bit of cryptocurrency for more than you paid, and the first worry is how big a slice SARS will take. The good news is that capital gains tax in South Africa is almost always smaller than people fear, because of how it is worked out and the exclusions built into it. This guide explains how capital gains tax works for the 2026/2027 tax year, what it costs on property, shares and crypto, and the legal ways to bring the bill down. When you want a number for your own situation, our capital gains tax calculator works it out in a few seconds.

What is capital gains tax?

Capital gains tax, or CGT, is the tax you pay on the profit when you dispose of an asset. A disposal is not only a sale. It also includes a donation, an exchange of one asset for another, the loss or scrapping of an asset, emigration, and death, when you are treated as having sold everything you owned at market value. The profit itself is the capital gain, and it is simply your proceeds, what you received, less your base cost, what the asset cost you. CGT has applied in South Africa to disposals on or after 1 October 2001, so anything you bought before then has special base cost rules.

The most important thing to understand is that capital gains tax is not a separate tax with its own rate. It is part of your normal income tax. A portion of your gain is added to your taxable income for the year, and taxed along with your salary at your ordinary rates.

The biggest myth: capital gains tax is not a flat 40 percent

Ask around and someone will tell you CGT is 40 percent. It is not. For an individual, 40 percent of your net gain is included in your taxable income, and only that included part is taxed, at your marginal rate. Because the highest income tax rate is 45 percent, the most an individual can ever pay is an effective 18 percent of the gain, which is 40 percent multiplied by 45 percent. In practice most people pay far less, because their marginal rate is lower and the exclusions come off first.

Here is the shape of it. Say you have a taxable capital gain of R400,000 after exclusions. Forty percent of that, R160,000, is added to your income. If that slice is taxed at a 31 percent marginal rate, the tax is about R49,600, which is roughly 12 percent of the original R400,000 gain, not 40 percent. Your income matters, because the taxable slice stacks on top of what you already earn, which is why a good calculator asks for your income rather than assuming the worst.

How to work out your capital gain

Start with the proceeds, the amount you sold the asset for. Then subtract the base cost. Base cost is more than just the purchase price. It includes:

• what you originally paid for the asset;
• the cost of buying it, such as transfer duty, conveyancing and legal fees on a property, or brokerage on shares;
• permanent improvements that added value, like a new roof or an extra room, but not repairs or normal maintenance;
• the cost of selling, such as estate agent commission and advertising.

Every rand of base cost is a rand less gain, so it pays to add up all of it and keep the records. Proceeds minus base cost gives your capital gain. If it is negative, you have a capital loss, which is covered below.

The exclusions that cut your bill

Several exclusions reduce the gain before any tax is worked out. These are the 2026/2027 figures, several of which went up in the February 2026 Budget.

The annual exclusion of R50,000 means small gains often pay no CGT at all, and it applies once a year across all your gains and losses combined, not once per asset. The primary residence and small business exclusions are the big ones for the people they apply to.

Capital gains tax on property

Property is where CGT bites hardest, and where the largest relief sits. If you are selling the home you actually live in, your primary residence, the first R3,000,000 of the gain is excluded. That figure was lifted from R2,000,000 in the 2026 Budget, so most ordinary home sales now attract no capital gains tax whatsoever. The relief is for a natural person, on land up to two hectares used mainly for domestic purposes, and it is reduced for any period you rented the home out or ran a business from it.

A second home, a holiday house, or any investment or rental property, including a buy to let, does not get the primary residence exclusion. Only the R50,000 annual exclusion applies, so the gain is largely taxable. For example, a rental flat bought for R1,200,000 with R80,000 of transfer and bond costs, sold for R2,000,000 after R100,000 of agent commission, has a base cost of R1,280,000 and net proceeds of R1,900,000, a gain of R620,000. After the R50,000 annual exclusion, 40 percent of R570,000, which is R228,000, is added to your income and taxed at your marginal rate. On a middle income that is roughly R70,000 to R80,000 of CGT. If you are buying again, the transfer duty and bond cost calculator and the buy to let calculator handle the next step.

Capital gains tax on shares and unit trusts

Selling shares, exchange traded funds or unit trusts for more than you paid is a capital gain, taxed on the same 40 percent inclusion basis, with your R50,000 annual exclusion but no primary residence exclusion. Your base cost is the price you paid plus the brokerage on both the buy and the sell. Two points are worth knowing. Inside a tax free savings account there is no capital gains tax at all, which is one of the strongest reasons to use one. And if you trade very actively, moving in and out over short periods, SARS may treat your profits as ordinary income taxed in full at up to 45 percent, rather than as capital gains at the gentler inclusion rate. The line between investing and trading comes down to your intention and how you behave.

Capital gains tax on crypto

SARS treats cryptocurrency as an intangible asset, not a currency, and has confirmed it is taxed under the existing rules. If you hold crypto as a long term investment, then selling it for rands, swapping one coin for another, or spending it are all disposals that trigger capital gains tax, with the same 40 percent inclusion and R50,000 annual exclusion as any other asset. But if you are an active trader, or you earn crypto through mining, staking, airdrops or as payment for work, that is revenue, taxed in full as normal income at up to 45 percent, not as a capital gain. SARS weighs your intention, how long you held the coins and how often you traded to decide which applies. Simply buying crypto with rands, or moving it between wallets you control, is not a taxable event.

What if I make a capital loss?

If you sell for less than the base cost, you have a capital loss. A capital loss can only be set off against capital gains, this year or in future years, never against your salary or other normal income. If you have no gains to absorb it now, the loss is assessed and carried forward until you do. That makes losses worth recording carefully, and it opens a planning option: realising an asset that is standing at a loss in the same year as a big gain sets the two off against each other.

How to legally reduce your capital gains tax

There is nothing dubious about these, they are how the system is meant to work.

• Claim your full base cost. Add every buying and selling cost and every permanent improvement. This is the most commonly missed saving.
• Use your annual exclusion. R50,000 of gain a year is free, and spreading disposals across more than one tax year uses it more than once.
• Set off losses. Realise a loss-making asset in the same year as a gain to reduce the net figure.
• Transfer between spouses. Assets pass between spouses with no capital gains tax, which can move a gain to the lower earner.
• Use the primary residence exclusion. For your home, the R3,000,000 exclusion usually removes the tax entirely.
• Hold investments in a tax free savings account, where no CGT applies.
• Time the disposal for a year when your income, and so your marginal rate, is lower.

When and how do you pay?

You declare the disposal in your income tax return for the year in which you sold the asset, and the capital gains tax forms part of your assessment. If you are a provisional taxpayer, a large gain may need to be built into your provisional payments during the year to avoid interest, so it is worth working the figure out early rather than waiting for filing season.

Frequently asked questions

How much capital gains tax will I pay in South Africa?

It depends on the size of your gain and your income. Work out the gain, take off the exclusions, then 40 percent of what is left is added to your income and taxed at your marginal rate. Because only 40 percent is taxed, the effective rate on the whole gain is well below 40 percent, and for an individual it can never exceed 18 percent. The calculator gives your exact figure.

Do I pay capital gains tax when I sell my house?

Usually not. If it was your primary residence, the first R3,000,000 of the gain is excluded for 2026/2027, so most ordinary home sales attract no CGT. A second home, holiday house or rental property does not get that exclusion and is largely taxable.

What is the capital gains tax rate in South Africa?

There is no single rate. For an individual, 40 percent of the net gain is included in taxable income and taxed at your normal rate, giving a maximum effective rate of 18 percent. Companies include 80 percent and trusts other than special trusts include 80 percent.

Is crypto taxed as capital gains or income?

It depends on how you use it. Held as a long term investment, a disposal is a capital gain. Active trading, or crypto earned from mining, staking or as payment, is revenue taxed in full as income at up to 45 percent. SARS looks at your intention, holding period and trading frequency.

Can I reduce my capital gains tax legally?

Yes. Claim your full base cost including all costs and improvements, use your R50,000 annual exclusion and spread disposals across tax years, set off any losses, transfer assets between spouses, use the primary residence exclusion and a tax free savings account, and time a disposal for a lower income year.

What happens if I make a capital loss?

A capital loss cannot be set off against your salary, only against capital gains. If you have no gains this year it is carried forward to reduce CGT on a future disposal, so keep the records.

This guide is general information based on the 2026/2027 SARS rules, not tax advice. It assumes you are a South African tax resident. For a large or complex disposal, an asset owned before 1 October 2001, foreign assets, or gains inside a company or trust, confirm your position with SARS or a registered tax practitioner.
