Category A: Tax uncertainty in your tax return

Last updated 24 August 2021

A Category A reportable tax position is one where, given relevant authorities, you consider the material position taken is either:

  • about as likely to be correct as incorrect, even if it is reasonably arguable
  • is less likely to be correct than incorrect.

You must disclose a material position, even if it is based on administrative or industry practice, that:

  • doesn't have regard to relevant authorities, or there are none
  • isn't based on a well-reasoned construction of the applicable statutory provision.

You must have regard to all matters relevant to the position including:

  • anti-avoidance rules
  • integrity provisions
  • transfer pricing
  • market valuations.

A position will be material where the potential adjustment, should the position not be sustained, is equal to or exceeds your entity's materiality amount.
