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 be included in the Genuine Redundancy amount.
See the ATO for more information on the payments you include in a genuine redundancy.
When processing a Redundancy Termination and the In Lieu of Notice has been included in the Genuine Redundancy, the superannuation value for the In Lieu of Notice will not automatically calculate. You will need to complete a separate Manual Calculation for the superannuation.
