11When does a liability for duty arise?

11 When does a liability for duty arise? (1) A liability for duty payable under this chapter arises— (a) when a transfer of dutiable property occurs; or (b) if a transfer of dutiable property is effected by an instrument— when the instrument is first executed. (2) However, a liability for duty payable under this chapter must not be paid until it becomes payable under section 16 (When does duty become payable?). (3) To remove any doubt, the commissioner may assess the liability for duty payable under this chapter before the duty becomes payable under section 16.
