If the In Lieu of Notice is to be included as part of the tax-free up-to-limit, (depending on the employee's years of service) this value will need to include in the Genuine Redundancy amount.
For more information on, the payment you may include in a genuine redundancy, click on the ATO link here ATO.
When processing a Termination for a Redundancy payment and the In Lieu of Notice has been included in the Genuine Redundancy Amount, the superannuation value for the In Lieu of Notice value will not automatically calculate.
You will need to complete a separate Manual Calculation for the superannuation values.
