If the TPD payout is received as a lump sum, it is generally tax-free if it is paid from a superannuation fund or a life insurance policy held outside of superannuation. However, if the payout includes an amount for lost salary or wages, this portion may be taxed as a superannuation lump sum.
On the other hand, if the TPD payout is received as an income stream, it will be taxed as regular income. The tax treatment will depend on the individual's marginal tax rate and any applicable tax offsets.
It's important to note that these tax rules can be complex, and the specific tax treatment of a TPD payout will depend on the individual's circumstances. It's always a good idea to seek advice from a qualified tax professional before making any decisions that could impact your tax liability.
