Adjustment of contracts on changes in GST
Generally, you should charge GST at 8% on your supplies made on or after 1 Jan 2023 arising from your existing contracts entered into before 1 Jan 2023. If the contract explicitly excludes any change in the tax charged or has taken the tax change into account, you will be bound by the contract terms and will not be able to revise the consideration. In such cases, you should still account for GST at 8/108 of the total consideration.

Filing of GST return for adjustments of GST
Example: Reporting adjustments in the GST return
I have issued a tax invoice with 7% GST charged for my sales of goods on 20 Dec 2022 but the goods are delivered and payment is received on 9 Jan 2023. On 12 Jan 2023, I issue a credit note to cancel the original tax invoice and issue a new tax invoice charging GST at 8% on the supply. How do I report the supply and adjustments in my GST return?
If your quarterly GST return ends in Mar 2023
|You should report the supply and adjustments as follows:|
(a) In the GST F5 return for the period ended 31 Dec 2022, the original tax invoice charging GST at 7% issued in Dec 2022.
(b) In the GST F5 return for the period ended 31 Mar 2023, adjustments for the credit note and the new tax invoice issued in Jan 2023.
