The 2026-27 Federal Budget proposed to introduce a 30% minimum tax on taxable income of discretionary trusts from 1 July 2028. The original proposal raised concerns as it was suggested to apply to discretionary testamentary trusts, potentially affecting trusts established by a will for a legitimate succession planning purpose. Following consultation, the Government has amended the proposal to exclude genuine testamentary trusts from the new minimum tax, subject to integrity requirements to ensure that they are designed for a legitimate purpose.
