Right now, if you have a Pension Account that is higher than $3M it is tax free.
When you start a pension account you start it with what is referenced as a TBC or Transfer Balance Cap
This is the amount you set aside from your Super Balance to fund the Pension portion. Depending on when you started it, it could be $1.6M to $1.9M and soon to be $2M. Any amounts above the TBC limit at time of starting said Pension remains in Accumulation mode and taxed. All Earnings and Interest and Capital Gain in the TBC are tax free. If the Pension account amount grows above the TBC level, it still remains tax free.
