Taxes on Trading Income in South Africa: SARS Rules and Compliance

How trading income is taxed in South Africa

Whether SARS treats your results as ordinary revenue at your marginal rate or as capital gains on disposal depends on how the activity is characterised. That characterisation is a factual enquiry rather than something you elect, and it drives every downstream obligation:

• PAYE irrelevance
• Provisional tax exposure
• Deductibility of expenses
• Treatment of losses

The content below is general information for an advanced reader. Individual tax outcomes turn on facts, residency and the specific instrument, so verify your position with a registered tax practitioner before filing. All figures referenced come from the South African Revenue Service and the Income Tax Act 58 of 1962.

Trader versus investor: how SARS classification shapes your tax bill

SARS applies a revenue-versus-capital enquiry grounded in case law, notably CIR v Pick 'n Pay Employee Share Purchase Trust and the Natal Estates line. The decisive factors include intention at acquisition, the scheme of profit-making, holding period, frequency and continuity of transactions, degree of organisation, and whether borrowed funds finance the activity. Short holding periods, high turnover and reliance on price action tend to indicate a trade, whereas a buy-and-hold approach driven by dividend intent generally supports a capital characterisation.

The tax consequence is material: revenue-account profits are included in gross income under section 1 and taxed at marginal rates, reaching 45% for taxable income above R1,817,000 in the 2024/25 brackets published by SARS. Capital-account gains fall under the Eighth Schedule: individuals include 40% of the net gain in taxable income, producing a top effective CGT rate of 18%, after the annual exclusion of R40,000.

Active forex and CFD traders almost always fall on the revenue side, whereas equities held primarily for yield are generally more defensible as capital.

SARS reporting requirements and compliance deadlines

All trading results are declared on the ITR12 for the year of assessment ending 28 February. The 2024 filing season for non-provisional individuals ran from 15 July to 21 October 2024, with provisional taxpayers filing until 20 January 2025, according to SARS. Revenue-account traders complete the local business, trade and professional income section; capital-account activity goes in the CGT schedule with per-asset base cost and proceeds.

Declaration comes down to source documents. For each closed position you need the following records:

• Trade date
• Instrument
• Entry and exit price
• Quantity
• Broker fees
• The ZAR conversion used where the account is denominated in a foreign currency

SARS accepts either the spot rate on the transaction date or the average rate published by the South African Reserve Bank, provided the chosen basis is applied consistently throughout the year. Late or incomplete returns trigger administrative penalties under section 210 of the Tax Administration Act, scaled to taxable income, with interest accruing at the prescribed rate.

Tax deductions and record-keeping for active traders

If your activity is a trade, section 11(a) read with section 23(g) allows deduction of expenditure actually incurred in the production of income and not of a capital nature. For a screen-based trader that typically includes:

• Broker commissions, spreads treated as part of the trade cost, financing charges and swap fees
• Platform and data subscriptions (TradingView, Bloomberg, exchange data)
• Dedicated hardware depreciation under section 11(e) and the Binding General Ruling schedule
• A pro-rata home office claim where section 23(b) requirements are met: a specifically equipped area used regularly and exclusively for the trade
• Professional fees paid to tax practitioners and accountants

Educational costs are deductible only where they maintain existing skills; the cost of acquiring a new skill is capital in nature and disallowed, consistent with the SARS Interpretation Note on training expenditure.

Section 29 of the Tax Administration Act requires taxpayers to retain records for five years from the date of submission, or indefinitely while an audit is open. Rather than attempting to reconstruct everything at year-end, it is far safer to export monthly broker statements as they arrive, store them unaltered, and maintain a parallel trade log that you can tie back line by line to those statements.

Suppose you run a R500,000 CFD account, pay R42,000 in commissions and R18,000 in platform and data fees across the year, and claim 15% of a R72,000 home running cost as a qualifying home office portion. Deductible expenses in that hypothetical reach R70,800 before any depreciation, applied against gross trading profit on the revenue side.

Provisional tax payments for traders with significant income

A trader with non-salary income above the thresholds in paragraph 1 of the Fourth Schedule is a provisional taxpayer. Two compulsory IRP6 submissions are due: the first by the end of August (six months into the year of assessment) and the second by the end of February. A voluntary third 'top-up' payment is available by the end of September for non-companies, used to avoid section 89quat interest where the first two estimates fell short.

Under-estimation penalties bite when taxable income exceeds R1 million and the second-period estimate is less than 80% of actual taxable income: SARS levies 20% of the shortfall. Below R1 million, the 'basic amount' safe harbour applies if the estimate is at least 90% of actual or equal to the basic amount from the last assessed return. Late payment attracts a 10% penalty under paragraph 27, with interest running at the prescribed rate from the due date.

Offshore brokers, local brokers, and tax implications

South African tax residents are taxed on worldwide income, so forex tax in South Africa follows the trader regardless of broker domicile. Offshore accounts are reportable; failure to disclose foreign financial interests triggers the understatement penalty table in section 223, which runs from 25% to 200%.

South Africa's double taxation agreements, including those with the United Kingdom, United States and Mauritius, allow a section 6quat rebate for foreign tax paid on the same income, capped at the SA tax attributable to that foreign amount. Because the rebate operates as a credit against SA tax rather than as a deduction from income, you must retain proof of the foreign tax actually paid.

Crypto assets are defined as financial instruments in the Income Tax Act since the 2021 amendment, confirmed by SARS guidance. Disposal gains follow the same revenue-versus-capital test; mining and staking rewards are revenue on receipt at market value. Crypto-to-crypto swaps are disposals, each leg valued in ZAR.

Tax-loss harvesting and loss carry-forward rules

Revenue-account traders set assessed losses off against other taxable income in the same year under section 20, and carry the balance forward indefinitely while the trade continues. Section 20A ring-fences losses from 'suspect trades' for individuals in the top bracket where the activity shows a pattern of losses and features such as part-time involvement; the ring-fence confines the loss to future income from the same trade.

Capital losses cannot be offset against revenue income: they are ring-fenced within the CGT system and carried forward only against future capital gains.

Tax-loss harvesting on the revenue side means timing the realisation of losing positions before 28 February to compress the current-year tax base. South Africa has no formal wash-sale rule, but the general anti-avoidance provisions in sections 80A to 80L apply where a transaction lacks commercial substance and is entered into for a tax benefit. Closing and immediately reopening the same position at the same price, with no economic exposure change, is the pattern SARS will attack.
