On 13 October 2025 the government announced changes to the proposed legislation. Key changes are as follows.
Original proposal | New proposal |

The threshold for the additional 15% tax (ie 30%) applied on super balances above $3 million | The threshold for the additional 15% tax would remain at $3 million, but there would also be a further 10% tax (ie 40%) on balances above $10 million |
The tax would be applied on unrealised gains | The tax would not be applied on unrealised gains – only on realised earnings |
There were no plans to index the thresholds | The thresholds will be indexed to the transfer balance cap (currently $2m) |

The details contained in the following guide (and the calculator) relate to the original proposal. We will update this guide as soon as the government provides more detail.
