"First case: I did a tax return for a young lady who worked in an office, total deductions $220, expected refund $454.41. She was not happy with this so she gave me the flick and did it herself on e-tax - result a refund of $ 6,148.36.
Second case: I did a tax return for a chap that worked for a bank, estimated refund $286.56. He also was not happy with my work because he copied my return into e-tax and got a refund of nearly $2,500. When I pointed out that he had claimed a spouse rebate when his wife received FTB A & B he just laughed and said he already had the money.
The ATO were crowing that low doc loans were a great source for catching people cheating, I think it's time to put a couple of auditors on e-tax."
