(1) You may use this set of rules for any type of expense except the decline in value of a * depreciating asset.
(2) You must get a document from the supplier of the goods or services the expense is for. The document must set out:
(a) the name or business name of the supplier; and
(b) the amount of the expense, expressed in the currency in which it was incurred; and
(c) the nature of the goods or services; and
(d) the day the expense was incurred; and
(3) There are 2 exceptions to these requirements:
(a) if the document does not show the day the expense was incurred, you may use a bank statement or other reasonable, independent evidence that shows when it was paid;
(b) if the document the supplier gave you does not specify the nature of the goods or services, you may write in the missing details yourself before you lodge your * income tax return for the income year.
(4) The document must be in English. However, if the expense was
incurred in a country outside Australia, the document can instead be in a
language of that country.
