ever y year is ta x-f ree, so you only pay CGT on any capital gains above R30 000. This R30 000 t a x-f ree amount is across all assets, so if you made a capital gain elsewhere that would have to be i ncluded i n your capital gains amount for tax purposes.
Another important point is that CGT came into existence on 1 October 2001, so if you bought a share before that date you would use the 1 October 2001 price as your effective purchase price for any CGT. Your broker will have this price readily available.
If you are a trader as def ined by Sars (t ransacting i n derivatives or holding less than three years), then it defines any profits as revenue, and your effective rate of tax on your gains is your marginal rate.
If trading is def ined as revenue, you can deduct all expenses from your income (prof it). So brokerage fees, data fees, magazine subscriptions and the l ike are all deducted from your profits before declaring a profit for tax purposes. You are also able to deduct all losing trades from your profits so at the end of the day you pay the tax on your ultimate profits, not profit per trade.
You can also claim expenses pro rata. For example, i f you use your computer half the time for trading and the other half for personal use you can claim half of the costs as a trading expense.
A l ast point is to keep excellent records. Your broker will provide CGT and profit/ loss reports, but ultimately documents, proof of profits and costs are your responsibility. I would also suggest using separate accounts for your trading and investing activities. Your broker should be able to offer this function at no extra cost and it will help keep your tax liabilities clean and easy to identify.
