I had to backdate for GST. I reached the threshold in November and mistakenly didn't register. This has since been cleared up with ATO. However I now need to fill out my BAS for the quarter (OCT-DEC).
During this time I received one payment, I did not charge GST on the invoice as I wasn't registered at the time. I assume that this still is treated as a taxable sale, and 1/11 of the total payment will be treated as GST?
Will my "total sales" just be the amount of the total payment i received?
Do I then click 'No' for does this include GST? Because I mistakenly didn't charge GST. Or do i click 'Yes' because i was supposed to charge GST, and then the GST on sales is what it was "supposed" to be, that 1/11th of the total sale mentioned earlier.
I hope my question makes sense.
Any help is much appreciated, Im just confused about navigating this first bas since the GST wasn't charged but it should've been.
