Following our release of the draft for consultation in December 2025, we've now published the final version of the addendum to TR 2017/1 Income tax: deductions for mining and petroleum exploration expenditure.
This ruling clarifies the Commissioner's view on the ordinary meaning of ‘exploration or prospecting’ in the context of Division 40 of the ITAA 1997.
Now it's finalised, this update will apply both before and after its date of issue.
We encourage you to familiarise yourself with the updated product to understand your obligations.
For more information, you can read TR 2017/1 on our legal database and see the consultation feedback.
