Taxation of options in Australia — Basics (k4)
A concise guide to common tax outcomes for buyers, writers and traders of options on Australian markets (ASX). This covers exercise, lapse, premiums, and record-keeping fundamentals for retail traders and investors.
Key principles — income vs capital
In Australia options may be taxed as capital gains or ordinary income depending on purpose and frequency. Key determinants include whether the activity is part of a profit-making scheme (business) or an investment held on capital account.
Common scenarios with examples
Example A — Buying a call and exercising
Buy call for $3 premium, strike $5, exercise later. Your cost base in acquired shares = strike ($5) + premium ($3) + incidental costs. If sold later, CGT applies based on capital gain or loss.
Example B — Writing (selling) options
Writer receives $2 premium. If writing is not part of a business, the premium might still be assessable as income. If the option is covered and part of a broader capital strategy, the premium can be treated in capital account—circumstances vary.
Record-keeping & practical tips
Keeping clear records is essential for accurate tax treatment and reporting to the ATO. Store confirmations, broker statements, contract notes and a simple trading log.
- Record date, strike, premium, fees and whether exercise occurred.
- Separate personal investment activity from business-like trading.
- Consider whether the ATO's profit-making test applies in frequent trading.
