Hello. Just realised I made a blunder in December last year (2020). I paid an employee redundancy pay when he left the company and I incorrectly assigned it to Lump Sum A instead of Lump Sum D. His his tax agent worked out that it should have been in Lump Sum D and a TAX FREE payment however he is now having trouble with Centrelink re his income declaration. I need to fix this. I presume I have to 'remove finalisation' but then what to do?? It is in last years payroll year so am presuming I can not go back and fix it?? Help please! Many thanks!
