(1) The GST payable by you on a * taxable supply is attributable to:
(a) the tax period in which any of the * consideration is received for the supply; or
(b) if, before any of the consideration is received, an * invoice is issued relating to the supply--the tax period in which the invoice is issued.
(2) However, if you * account on a cash basis, then:
(a) if, in a tax period, all of the * consideration is received for a * taxable supply--GST on the supply is attributable to that tax period; or
(b) if, in a tax period, part of the consideration is received--GST on the supply is attributable to that tax period, but only to the extent that the consideration is received in that tax period; or
(c) if, in a tax period, none of the consideration is received--none of the GST on the supply is attributable to that tax period.
