This non-exhaustive checklist is designed to provide an easy reference guide to the types of deductions that might be claimed by businesses.

Note that these deductions may not necessarily be available, and before deciding on the deductibility of an outgoing, the business’s particular circumstances should be taken into account.

All businesses are required to maintain records of every transaction that relate to their income and expenditure as well as CGT transactions, GST, FBT and other requirements. If there is any private use element, that should also be noted in the records. Car and travel expenses must be substantiated.

Note: All section and division references are to the Income Tax Assessment Act 1997 (ITAA97) unless otherwise stated.
