Super strategies – Contribute to super and offset capital gains tax

When contributing to super, claiming a portion of the contribution as a tax deduction could enable you to pay less capital gains tax and increase your retirement savings.

How does the strategy work?

Other key considerations

Cashing out a non-super investment, paying capital gains tax (CGT) and using the remaining amount to make a personal super contribution can be a powerful strategy.

This is because the low tax rate payable on investment earnings in super could more than compensate for your CGT liability over the longer term.

However, if you meet certain conditions, you may want to claim a portion of your super contribution as a tax deduction to offset some (or all) of your taxable capital gain and reduce (or eliminate) your CGT liability.

While the tax-deductible portion of your super contribution will be taxed at 15%¹ in the fund, this strategy could enable you to make a larger super investment and retire with even more money to meet your living expenses.

  • Personal deductible contributions count towards the ‘concessional contribution’ cap (which is $25,000 in 2020/21) and tax penalties apply if you exceed the cap.
  • You can’t access super until you meet certain conditions.
  • If you did not use up your concessional contribution cap in 2018/19 or 2019/20 and meet certain conditions, you may be eligible to carry forward the unused cap amount. This could enable you to make concessional contributions exceeding the annual cap in 2020/21  or the following financial years.


¹ Individuals with income above $250,000 in 2020/21 will pay an additional 15% tax on concessionally tax super contributions.


Case Study:

Lisa, aged 42, is self-employed, earns a taxable income of $90,000 pa and has a share portfolio worth $50,000. She wants to sell her shares and invest the money in super so she can boost her retirement savings. The sale of these shares will crystallise a taxable capital gain of $10,000².

She could make a personal after-tax super contribution of $46,100 (after keeping $3,900³ to pay CGT on the sale of the shares).

However, her adviser suggests that a better approach may be to invest the full sale proceeds of $50,000 in super and claim $10,000 as a tax deduction, subject to receiving tax advice from her  registered tax agent.

By doing this, she can use the deduction to offset her taxable capital gain of $10,000 and eliminate her CGT liability of $3,900.


While the deductible contribution will be taxed at 15% in the super fund, this strategy will enable her to invest an additional $2,400 in super for her retirement.


² This figure is after the 50% general CGT discount (that is available because Lisa has owned the shares for more than 12 months) and assumes she has no capital losses to offset her taxable capital gain.

³ Based on a marginal tax rate of 37%, plus Medicare levy of 2%. Does not include the Low and Middle Income Tax Offset.
