From www.heffron.com.au: When a pensioner dies, their account-based pension stops, and trustees are no longer required to make payments.
It is crucial to keep the pension account intact because it maintains its tax-free component and ensures correct fund tax liability, allowing it to attract exempt current pension income (ECPI) until the death benefit is cash-paid.
Trustees must cash death benefits as soon as practicable; however, the timeframe for this depends on specific circumstances.
