(1) You may make an * annual apportionment election if you are eligible under section 131-5.
(2) Your election takes effect from:
(a) the start of the earliest tax period for which, on the day on which you make your election, your * GST return is not yet due (taking into account any further period the Commissioner allows under paragraph 31-8(1)(b) or 31-10(1)(b)); or
(b) the start of such other tax period as the Commissioner allows, in accordance with a request you make in the * approved form.
Note: Refusing a request to allow your election to take effect from the start of another tax period is a reviewable GST decision (see Subdivision 110-F in Schedule 1 to the Taxation Administration Act 1953 ).
