Crypto derivatives and perpetuals

Crypto futures, options and perpetual swaps ("perps") are financial contracts whose value derives from an underlying crypto asset. They are taxed differently from simply holding the coin, and the character of the gains often leans revenue because trading derivatives is typically a profit-making, business-like activity. Treatment is technical and evolving — get advice.

Why derivatives often look like revenue

Trading perps and futures usually involves leverage, frequent positions, short holding periods and a clear profit-making intention — the hallmarks of revenue rather than capital. Where that is the case, gains are fully included in income and taxed at your marginal rate (18%–45%), with no R40,000 exclusion or 40% discount, and losses may be deductible against income subject to the rules.

Funding, fees and settlement

  • Funding payments on perpetual swaps (periodic payments between long and short holders) are part of the economics of the position and should be tracked.
  • Fees (trading, financing) affect your net result.
  • Settlement — whether cash-settled or settled in crypto — affects how and when a gain or receipt arises; physical settlement can itself be a disposal/acquisition of the underlying.

Margin and liquidations

Posting margin, and liquidations when a position is force-closed, are taxable events to track — a liquidation crystallises the result of the position.

Record-keeping

Derivatives generate dense, frequent records. Capture each position's open/close, funding, fees and rand values. This is an area where manual tracking breaks down quickly.

Not tax advice

Derivatives taxation is complex and fact-specific — confirm with a registered tax practitioner.
