A proposed 15% additional tax on the portion of a superannuation fund member’s earnings attributable to a Total Super Balance above $3M, from the 2026-27 income year.
Applies on top of the existing 15% (accumulation) or 0% (pension) earnings tax. Calculated on a notional basis - change in TSB year on year, adjusted for contributions and withdrawals. Threshold is not indexed in the current proposal. Hits SMSF property holdings most directly when the fund crosses $3M.
