"More problems with ATO computer systems? I have just contacted the ATO regarding a debt which was supposedly overdue on a client ICA. The June 2010 BAS debt was $46,191 and a cheque was sent off by the client for that amount. However a payment of only $461.91 has been processed on the account, leaving a supposed debt of $45,729.09. And, of course, it was merrily incurring 'estimated GIC' as shown on the Portal. The ATO officer advised 'Oh yes, this seems to have happened a bit lately'. So watch out for a flood of 'Overdue Payment Reminders' clogging your mailbox!"
