An example of how the 30% tax floor impacts the current & future workforce looking to retire before Super preservation age. ($15k invested over 20 years @ 8% p/a return, inflation assumed at historical CPI, +-$70k draw down for retirement results in a person being $11.8k worse off)
This is just an example, in reality you probably wouldn't be using a lump sum investment, it's more to illustrate the point.
The changes seem to incentivise Australians to use Super more, however that has risks to reform such as raising the preservation age or taxing the distribution.

Inputs and calculation assumptions copied from the website:
- Tax rates: 2027–28 Australian resident individual income tax brackets after the legislated 1 July 2027 tax cut, excluding the Medicare levy, WATO, LITO and other offsets. Sources: ato.gov.au and Budget 2026–27.
- Excluded: 2% Medicare levy, Medicare levy surcharge, Working Australians Tax Offset (WATO), low income tax offset (LITO), HECS/HELP repayments, other levies, offsets and deductions. Your actual tax payable will differ.
- CPI data: Australian Bureau of Statistics series for All groups CPI, annual movement to December. The latest full December year used is 2025. CPI is historical — it is not a forecast and is not a reliable indicator of future inflation.
- Growth rate: Applied as the same nominal rate every year of the holding period. Real investment returns vary year to year.
- Real (CPI-adjusted) gain: Calculated as proceeds minus indexed cost base. With one initial cost base, this is equivalent to (Total growth %) − (Total CPI %), applied to the principal.
- CGT event: Assumes a single, fully realised capital gain on a non-superannuation asset held by an Australian tax resident individual for more than 12 months.
- 50% discount method: Discount available to individuals on assets held > 12 months. Assumes no capital losses to offset.
- Proposed "new rules": Hypothetical scenario where the inflation-adjusted gain is taxed at marginal rates with a 30% minimum tax on net capital gains, based on the 2026–27 Budget proposal. The Budget proposal starts from 1 July 2027 and only applies to gains arising after that date.
- Not modelled: brokerage and other transaction costs, dividends/distributions, franking credits, partial disposals, foreign income, trust/company/SMSF structures, and small business CGT concessions. It also excludes the Budget proposal's transitional split at 1 July 2027, valuation choices, income-support-recipient exemption from the minimum tax, and the new-build choice between methods.
