Taxation Administration Act 1953

A matter is reasonably arguable if it would be concluded in the circumstances, having regard to relevant authorities, that what is argued for is about as likely to be correct as incorrect, or is more likely to be correct than incorrect.

For the effect of transfer pricing documentation on when a matter is reasonably arguable, see Subdivision 284‑E.

To the extent that a matter involves an assumption about the way in which the Commissioner will exercise a discretion, the matter is only reasonably arguable if, had the Commissioner exercised the discretion in the way assumed, a court would be about as likely as not to decide that the exercise of the discretion was in accordance with law.

Without limiting subsection (1), these authorities are relevant:

a *taxation law;

material for the purposes of subsection 15AB(1) of the Acts Interpretation Act 1901;

a decision of a court (whether or not an Australian court), the Administrative Appeals Tribunal, the *ART or a Board of Review;

a *public ruling.
