It certainly is an issue in many ways and yet the death transfer of wealth with super can be overcome.
Encountered one last year. With the assistance of a financial planner, a dear lady in her 90's decided to wind up her fund as things weren't going well for her. So the fund paid a relatively small amount of tax and the assets were transferred to her. She passed away around three months later. The tax on her personal investment income was small but through her Will her named beneficiaries (with the agreement of her family, she skipped a generation with some of her assets) received (tax free) a seven figure amount each.
Not bad for a child to have over $1m of shares earning a conservative 3%, subject to adult tax rates and more than likely getting a refund of excess franking credits.
Avoided that death benefit tax and saved her beneficiaries heaps of tax i.e the G'ment didn't get anything much.
Starts the grey cells firing wondering if that issue will be addressed in the future.
