Q&A of the month
Q: I’ve seen examples online suggesting that making a concessional super contribution after a capital gain can reduce the tax payable. I don’t understand how this works. If a capital gain is already taxable, how does contributing the money to super reduce the tax? Does it change the tax rate on the gain, or is something else happening?
A: Making a tax-deductible (concessional) contribution to super can reduce tax on capital gains via the tax deduction.
For example, if taxable income (including taxable capital gain) would be $200,000 without action, making a tax deductible super contribution of $50,000 reduces taxable income to $150,000 and therefore reduces income tax (including tax on the capital gain that is included in taxable income). The $50,000 is then taxed at 15% on entry to super, instead of at the marginal income tax rate(s) that would otherwise apply.
The concessional contribution cap is $30,000 in 2025-26 but contributions above the cap are possible for those who are eligible to carry forward concessional cap space from prior years.
Importantly, if total income plus concessional super contributions exceeds $250,000 for the year, additional tax will apply to super contributions (Division 293 tax), and this reduces the benefit of the tax deduction.

Tip of the month
The end of the financial year is almost here. If your super balance was under $500,000 last 30 June and you have unused concessional cap space from 2020–21, now is your last chance to use it. Find out more about carry forward for concessional contributions.
