You may choose the small business retirement exemption or the small business rollover for the remaining amount of capital gain if you meet the conditions. Alternatively, you may choose both concessions for different parts of the remaining capital gain.
Small business retirement exemption
You can use your small business retirement exemption to disregard all or part of a capital gain. You can choose to apply the retirement exemption to any amount of capital gain remaining after you have applied the other concessions or before any other concessions.
The amount you choose to disregard is called the exempt amount. The amount of any capital gain that exceeds the CGT exempt amount does not qualify for this exemption. The exempt amount must not exceed your CGT retirement exemption limit. This is a lifetime limit of $500,000.
