The Australian Taxation Office (ATO) says that almost $9 billion are lost through people making what it considers to be dodgy claims on their personal tax returns. According to the ATO, 93% of the 9.6 million Australians who file an individual return get it about right but the rest are a problem.

ATO Deputy Commissioner Alison Lendon said that in a recent review that common mistakes like claiming deductions where there is no connection to income or not having records to show that an expense was incurred affected seven out of ten returns the ATO randomly selected for review. Are that many of us trying to dodge our obligations or is the ATO trying to scare us just as we're getting our tax returns ready?
