The Lego was not the only claim for money spent on kids. Another taxpayer claimed their children's sports equipment and sporting membership fees. Others claimed school uniforms, and before and after school care. And, others claimed, "the cost of raising twins," the "cost of raising three children" and simply, "New born baby expensive." Yes indeed, but the expenses, while often shocking to parents, are not deductible.  

Cars were also a favourite. The ATO says that "many" taxpayers tried to claim the full purchase price of their new cars as a tax deduction. This included the taxpayer who claimed the cost of the new car he bought for his mother as a gift. Nice gesture but still not deductible.

Medical and dental expenses also featured heavily. The most striking was the couple that claimed the cost of their dental expenses, "believing a nice smile was essential to finding a job." Medical and dental expenses in general are personal expenses and not deductible.

Also making the list was the couple who claimed the cost of their wedding reception as a tax deduction. 

The unusual claims all came from the 'Other' deductions section of the tax return. In order to claim an 'other' deduction, the expenses must be directly related to earning income and you need to have a receipt or record of the expense. If your expense relates to your employment, it should be claimed at the work-related expenses section of the return.
