When rulings are binding

A private ruling is binding on the Commissioner where it applies to an entity and the entity has relied on the ruling by acting (or omitting to act) in accordance with the private ruling. An entity can stop relying on a private ruling at any time (unless prevented by a time limit imposed by a tax law) by acting (or omitting to act) in a way that is not in accordance with the private ruling, and can subsequently resume relying on the private ruling by acting accordingly. The Commissioner cannot withdraw a private ruling. However, where the scheme to which a private ruling relates has not begun to be carried out and (where the private ruling relates to an income year or other accounting period) that period has not begun, the Commissioner can make a revised private ruling.
