Another key finding in the report was that the introduction of higher rates of taxation for balances over $3 million is projected to lead to a 9.5 per cent decrease in tax concessions in relation to investment earnings.

Those who will be affected are mostly aged 60 and over, with around two-thirds male. Around half are retired with those still in employment or business mostly involved in professional roles.

Additionally, the research revealed that insurance through superannuation, while not traditionally considered to be an equity measure, is a very effective redistributive mechanism that delivers substantial benefits to those most in need in Australian society.

Furthermore, as a result of increasing superannuation account balances, at Age Pension eligibility age an increasing proportion of retirees have substantial private incomes. The report stated only around 40 per cent of Australians aged 66 to 69 currently receive the Age Pension and that without super, there would be more than 500,000 extra individuals receiving the Age Pension.

ASFA Deputy CEO Glen McCrea said the upcoming federal budget provides an opportunity to further improve equity in Australia’s superannuation system.

“Introducing Superannuation Guarantee (SG) payments on paid parental leave and increasing the upper threshold for the Low Income Superannuation Tax Offset (LISTO) would substantially assist low to middle income earners, particularly women,” he said.
