General Anti Avoidance Rule: broad authority to recharacterise and deny tax benefits where arrangements lack commercial substance.
Clause 181 empowers tax authorities to neutralise tax benefits from arrangements lacking commercial substance by denying benefits (including treaty benefits) and imposing a range of consequences: disregarding or recharacterising steps or whole arrangements; treating arrangements as not entered into; treating accommodating or connected parties as one; reallocating tax attributes; recharacterising residence or situs; and looking through corporate structures. Clause 181(3) authorises reclassification of equity/debt and capital/revenue character. Rule 10UA limits consequences to the impermissible part of an arrangement, providing proportionality.
