🇿🇦 Crypto Tax Calculator — South Africa
2027 tax year (1 Mar 2026 – 28 Feb 2027). Estimate what SARS may tax on your crypto disposals. Buying and holding is not taxable; selling, trading coin-for-coin, or spending crypto is a disposal. Estimate only — always confirm with a SARS-registered tax practitioner.
Not financial, legal or tax advice. SARS does not publish an official crypto tax calculator. Rates: SARS individual tax table + rebates, 2027 tax year. Figures are an estimate to help you plan — your actual liability depends on your full return, records and SARS's view of your activity.
How crypto tax works in South Africa (the 3-step version)
- Work out your gain in rand. For each disposal: proceeds (what you sold/spent it for) minus cost basis (what you originally paid, including fees). Sum all disposals for the tax year.
- Decide: income or capital? If you trade frequently, SARS generally taxes crypto gains as income at your full marginal rate. If you buy and hold long-term, gains are usually capital: only 40% of the gain (after the R40 000 annual exclusion) is added to your taxable income.
- Add it to your taxable income and apply the SARS table. The calculator does this for you — your marginal bracket depends on your total income for the year.

Worked example
Suppose you bought bitcoin for R60 000 and later sold it for R150 000 (a R90 000 gain), and you earn a R350 000 salary. As a long-term holder (capital), the calculator adds R20 000 to your taxable income (R90 000 − R40 000 exclusion, × 40%). Your marginal rate rises into the 26–31% range — so the extra SARS tax on that crypto gain is roughly R5 000–R6 000 for the year. Run your own numbers above — example only.
Do I have to declare crypto to SARS?
Yes. SARS receives crypto exchange data directly under the Crypto-Asset Reporting Framework (CARF) — it can already see your disposals on South African exchanges. Declaring on your return and keeping records (date, rand value, amount, purpose) is far cheaper than a penalty.
Frequently asked questions
Is there an official SARS crypto tax calculator?
No — SARS does not publish an official crypto tax calculator. This tool applies the official SARS income tax tables and rebates to your crypto gain so you can estimate what you owe.
Do I pay tax if I only buy and hold bitcoin?
No. Buying and holding is not a taxable event in South Africa. Tax arises on disposal — selling, trading coin-for-coin, or spending.
Is crypto-to-crypto trading taxable?
Yes. SARS treats each crypto-to-crypto trade as a disposal of one asset and acquisition of another. The rand value at the time of trade forms both the proceeds and the new cost basis.
What records must I keep?
For each transaction: date, type, amount, rand value at the time, fees, and the purpose (trade vs investment). SARS can ask for these — keep them for at least five years.
