Technical tax area: Interpretation guidelines and interpretation statements
Interpretation guidelines discuss the Commissioner's approach to the interpretation of a general area of law where there are also taxation implications. For example, IG009: Employee or independent contractor? assists taxpayers to determine their employment status for tax purposes.
- Interpretation statements set out the Commissioner's view of the taxation laws in relation to a particular set of circumstances in cases when a binding public ruling cannot be issued or is considered to be inappropriate.
The table below lists interpretation guidelines and interpretation statements issued in 2015, other interpretations are sorted by the year in which they were issued.

IS 17/02 - Income tax – deductibility of farmhouse expenses
This Interpretation Statement explains that deductions for farmhouse expenses are available only to the extent that they are incurred in carrying on the farming business. This Interpretation Statement replaces a number of older items (some going back to the 1960’s) which allowed deductions which are no longer appropriate.
Where the compliance costs outweighs any likely deduction, the Interpretation Statement allows some sole traders and partners of partnerships to adopt a practical approach. This allows an automatic 20% deduction for farmhouse expenses and 100% deductions for rates and interest. These deductions are allowed when the value of the farmhouse is 20% or less than the total value of the farm.
