T girl - I had a lovely lady on the phone for the tax office help me out....Firstly the list they ask u for is basically your copies of group certificates. This will take up to 28 days to be sent out, so send off for it now and hope it gets here in time otherwise explain it couldnt be sent in time. If you have been good and kept all your tax info, you too should have copies of your group certificates, these will have your exact working dates with your employer and therefore solves any mysteries. Do get official copies from the tax office tho!
The letter the tax office asked me to send them was as follows -
My Name, Address, Tax File Number, DOB and signature.
Then the reason why i needed a 5yr payment summary (Group Certs) with Statuatory Declaration.
Please write when u need it by and that it is URGENT.
The fax number for the tax office is 02 93742688
Hope that helped!! Good Luck to all going - please let me know how u go!!
