(1) You have a decreasing adjustment if:
(a) you make a payment to an entity (the payee ) that acquires a thing that you supplied to another entity (whether or not that other entity supplies the thing to the payee); and
(b) your supply of the thing to the other entity:
(i) was a * taxable supply; or
(ii) would have been a taxable supply but for a reason to which subsection (3) applies; and
(c) the payment is in one or more of the following forms:
(i) a payment of * money or * digital currency;
(ii) an offset of an amount of money or digital currency that the payee owes to you;
(iii) a crediting of an amount of money or digital currency to an account that the payee holds; and
(d) the payment is made in connection with, in response to or for the inducement of the payee's acquisition of the thing; and
(e) the payment is not * consideration for a supply to you.
(1A) However, subsection (1) does not apply if:
(a) the supply of the thing to the payee is a * GST - free supply, or is not * connected with the indirect tax zone; or
(b) the Commissioner is required to make a payment to the payee, under Division 168 (about the tourist refund scheme), related to the payee's acquisition of the thing;
and you know, or have reasonable grounds to suspect, that the supply of the thing to the payee is a GST - free supply or is not connected with the indirect tax zone, or that the Commissioner is so required.
(2) The amount of the * decreasing adjustment is an amount equal to the difference between:
(a) either:
(i) if your supply to the other entity was a * taxable supply--the amount of GST payable on the supply; or
(ii) if your supply to the other entity would have been a taxable supply but for a reason to which subsection (3) applies--the amount of GST that would have been payable on the supply had it been a taxable supply;
taking into account any other * adjustments that arose, or would have arisen, relating to the supply; and
(b) the amount of GST that would have been payable, or would (but for a reason to which subsection (3) applies) have been payable, for that supply:
(i) if the * consideration for the supply had been reduced by the amount of your payment to the payee; and
(ii) taking into account any other adjustments that arose, or would have arisen, relating to the supply, as they would have been affected (if applicable) by such a reduction in the consideration.
(3) This subsection applies to the following reasons why your supply of the thing to the other entity was not a * taxable supply:
(a) you and the other entity are * members of the same * GST group;
(b) you and the other entity are members of the same * GST religious group;
(c) you are the * joint venture operator for a * GST joint venture, and the other entity is a * participant in the GST joint venture.
(4) However:
(a) paragraph (3)(a) does not apply if you and the payee are * members of the same * GST group when the payment referred to in paragraph (1)(a) is made; and
(b) paragraph (3)(b) does not apply if you and the payee are members of the same * GST religious group when that payment is made.
