Capital Gains Tax Calculator South Africa 2026/27
Estimate an individual’s taxable capital gain using the 2026/27 R50 000 annual exclusion, optional R3 million primary-residence exclusion and 40% inclusion rate. A user-entered marginal normal-tax rate provides a planning tax effect, not a full assessment.

Apply the annual exclusion once across the year and obtain a full calculation when a gain crosses tax brackets or residence rules are partial.
Capital gain and base cost
A capital gain starts with capital proceeds minus the asset’s established base cost. Proceeds can be cash or a market value required by the rules. Base cost can include the acquisition amount and qualifying acquisition, improvement, ownership and disposal costs, adjusted for amounts already deducted or otherwise excluded. It is not automatically the outstanding loan balance.
The page asks for one combined base-cost amount because eligibility of each receipt depends on the asset and prior tax treatment. Build a supporting schedule before entry. Including an expense already deducted from ordinary income can understate the gain, while missing brokerage, legal fees or qualifying improvements can overstate it.
2026/27 individual annual exclusion
For the 2026/27 year of assessment, the annual exclusion for an individual’s net capital gain or loss is R50 000. The 2026 Budget increased this amount from the previous R40 000. The calculator applies R50 000 when either individual exclusion option is selected.
The annual exclusion applies across the individual’s net capital gains and losses for the tax year, not independently to every asset. If several disposals occur, calculate and aggregate them under the statutory order before applying one annual exclusion. Entering each event on this calculator with R50 000 would overstate the benefit.
Primary residence exclusion
The 2026/27 primary-residence exclusion is R3 million of the qualifying capital gain or loss. The selector applies the full amount only as a scenario for an individual with a qualifying primary residence. It does not decide whether the property meets the definition or calculate a partial exclusion.
Business or rental use, a property larger than the permitted domestic area, periods of absence, more than one residence, deceased-estate events and ownership through an entity can change the result. Obtain a property-specific calculation before relying on a zero gain produced by the full exclusion.
Capital losses are ring-fenced to gains
Current and carried-forward capital losses generally reduce capital gains rather than salary, interest or rental income. The calculator subtracts the entered loss amount before exclusions. It cannot confirm that a loss is available, belongs to the same taxpayer or survives anti-avoidance and record requirements.
If proceeds are below base cost, the page reports no raw gain. It does not certify a capital loss because reduced base cost and special asset rules may differ. Calculate and document the loss separately for carry-forward purposes.
The 40% inclusion rate
After losses and applicable exclusions, an individual includes 40% of the net capital gain in taxable income. CGT is part of normal income tax, not a separate flat tax. At the top 45% marginal rate, the maximum effective rate on a fully included individual gain is 18%, calculated as 40% × 45%.
The tax field multiplies the included amount by one illustrative marginal rate. A large included gain can cross several progressive brackets, so a full before-and-after normal-tax calculation is more accurate. Rebates and other taxable income can also affect the assessment.
Worked investment example
Proceeds of R2.5 million less a R1.5 million base cost produce a R1 million raw gain. With no capital losses and the annual exclusion only, R950 000 remains. Applying the 40% inclusion rate adds R380 000 to taxable income.
At an illustrative 41% marginal rate, the tax effect is R155 800, equal to 15.58% of the raw gain. That figure is not sale cash: settling a bond, paying agents and receiving deposits affect cash flow, while qualifying costs should already be reflected in base cost.
Asset-specific rules
Shares acquired in parcels need parcel identification and brokerage records. Crypto disposals can include sales, swaps and use events. Personal-use assets and collectables have thresholds and restricted loss treatment. Trust distributions can contain capital-gain components and base-cost adjustments.
Companies and trusts have different inclusion rates and tax consequences, so this individual calculator should not be adapted by changing only the marginal-rate field. A trust beneficiary’s outcome depends on the distribution and tax rules; a company has its own rate and an 80% inclusion rate.
Records and applicable dates
Keep contracts, statements, invoices, valuations, ownership changes and calculations from acquisition through disposal. Property costs should distinguish capital improvements from repairs and amounts claimed against rental income. Records may be needed many years after purchase.
The relevant disposal event and proceeds can follow statutory timing rather than the bank-payment date. Donations, connected-person transfers and non-arm’s-length prices can trigger market-value rules. Confirm the event date and valuation basis with SARS guidance or a tax practitioner.
Valuation date and older assets
South Africa introduced CGT from 1 October 2001. An asset held before that valuation date needs a permitted valuation-date value method so pre-CGT growth is not simply treated as post-CGT gain. The chosen method, available records and time limits matter. Entering the original decades-old purchase price as the only base amount can materially overstate a taxable gain.
This calculator assumes the base cost entered already reflects the correct valuation-date treatment. Preserve any 2001 valuation, time-apportionment calculation or proceeds-based method working with the asset file.
Death-year exclusion and deceased estates
The annual exclusion in the year of an individual’s death is different from the ordinary R50 000 amount. Deemed disposals, transfers to a surviving spouse or estate, primary-residence treatment and later disposal by an estate can interact. Do not use the ordinary annual selector for a death event.
An executor should obtain estate-specific tax advice and align values used for estate duty, CGT and beneficiary records. The same market valuation may support several filings but each tax has its own rules.
Donations and connected persons
Giving an asset away can trigger a disposal at market value for CGT even when no cash is received, and donations tax may also need consideration. A transfer between connected persons at a nominal price does not automatically make the nominal amount the correct proceeds.
Obtain a defensible valuation at the event date and consider both donor and recipient records. The recipient’s future base cost must be documented so the same value is applied consistently.
Questions that affect this result
Is CGT charged at a separate flat rate?
No. Forty percent of an individual’s net capital gain is included in taxable income, where progressive normal-tax rates apply.
Can a capital loss reduce my salary tax?
Generally no. Capital losses are used against capital gains and can be carried forward subject to the rules and records.
Does every asset receive a R50 000 exclusion?
No. The annual exclusion applies once to the individual’s aggregated net capital gain or loss for the tax year.
Is every home sale covered by the R3 million exclusion?
No. The property and use must qualify as a primary residence, and partial business, rental or absence periods can require apportionment.
Why is the maximum effective individual rate 18%?
The maximum 45% marginal normal-tax rate applied to the 40% individual inclusion produces 18% before other interactions.
