When you sell a business asset at a profit, you normally pay CGT on the capital gain at your marginal tax rate. Division 152 of the Income Tax Assessment Act 1997 provides four concessions that can significantly reduce or eliminate this tax — potentially saving hundreds of thousands of dollars.
The 15-year exemption is checked first because it can disregard the whole gain without first using capital losses. If it does not apply, current-year and carried-forward capital losses come before the general CGT discount and the remaining Division 152 concessions.
1. 15-year exemption (Subdiv 152-B)
The entire capital gain may be exempt if the asset was continuously owned for at least 15 years and the relevant individual is permanently incapacitated, or is at least 55 and the CGT event happens in connection with retirement. The basic conditions, including the active asset test, must also be met.
2. 50% active asset reduction (Subdiv 152-C)
After applying the general 50% CGT discount (for assets held 12+ months), you get an additional 50% reduction on the remaining gain. This means only 25% of your original gain is potentially taxable — before the retirement exemption.
3. Retirement exemption (Subdiv 152-D)
You can exempt up to $500,000 of capital gains over your lifetime. If you're under 55, the exempt amount must be paid into a complying superannuation fund. This cap is tracked cumulatively across all CGT events where you claim the exemption.
4. Small business rollover (Subdiv 152-E)
Any remaining capital gain after the other concessions can be deferred by acquiring a replacement active asset within 2 years (or 4 years for compulsory acquisitions). The gain isn't eliminated — it's deferred until you sell the replacement asset.
Say you sell a business asset for $700,000 that you purchased for $200,000 (with $50,000 in costs), held for 8 years, earning $80,000 in other income:

This calculator uses 2026-27 resident individual tax rates and the Medicare levy, including the low-income levy calculation. It only applies Division 152 concessions when you confirm the active asset test. Trust outcomes are shown using the entered individual's income as an illustration; stakeholder and distribution rules can change the actual result. Companies and super funds are outside scope.
