(1) You have a decreasing adjustment if:
(a) you made an acquisition on the basis that:
(i) it was not a * creditable acquisition because the supply to which the acquisition relates was not a * taxable supply; or
(ii) it was * partly creditable because the supply to which the acquisition relates was only partly a taxable supply; and
(b) you provided * additional consideration for the acquisition in compliance with a contractual obligation that required you, or had the effect of requiring you, to provide additional consideration if:
(i) in a case where subparagraph (a)(i) applies--the supply was later found to be a taxable supply, or to be partly a taxable supply; or
(ii) in a case where subparagraph (a)(ii) applies--the supply was later found to be a taxable supply to a greater extent; and
(c) GST on the supply has not ceased to be payable (other than as a result of its payment); and
(d) at the time you provided the additional consideration, you were no longer entitled to an input tax credit for the acquisition.
Note: Section 93-5 or 93-15 may provide a time limit on your entitlement to an input tax credit.
(2) The amount of the * decreasing adjustment is the difference between:
(a) what would have been the * previously attributed input tax credit amount for the acquisition if:
(i) the * additional consideration for the acquisition had been provided as part of the original * consideration for the acquisition; and
(ii) in a case where you have not held a * tax invoice for the acquisition--you held such an invoice; and
(iii) subsection 29-10(4) did not apply in relation to the acquisition; and
(b) the previously attributed input tax credit amount.
(3) To avoid doubt, additional consideration for an acquisition includes a part of the * consideration for the acquisition that:
(a) relates to the amount of GST payable on the * taxable supply to which the acquisition relates; and
(b) at the time of the acquisition, the parties to the transaction under which the acquisition was made assumed was not payable.
