I started my business in December 2022 as a sole trader. I did not expect to reach the AU$75K before the end of the FY 2022/23 so I did not register for the GST and I did not charge my customer GST on my service invoices.
In May 2023 I realised that I will have exceed the AU$7k by end of June 2023 so I registered for the GST staring early June.
I am now preparing the BAS for Q4 2022/23. My income for the quarter includes 2 months where I did not collect GST and 1 month where I will collect GST.
How much GST should I include in the BAS?
The amount I actually charged the customer in the June Invoice or 10% of my total business income for the first 2 months of the Quarter the and amount I actually charged the customer in the June Invoice?
