If your GST turnover is $10 million or more, you must use the full reporting method to report your GST. Using this method, you are required to separate your GST sales and purchases into categories (for example, export sales, non-capital sales, other GST-free sales, capital purchases, GST on purchases, etc).

You will need to complete a calculation sheet and complete 7 labels on your BAS:

• G1 Total sales
• G2 Export sales
• G3 Other GST-free sales
• G10 Capital purchases
• G11 Non-capital purchases
• 1A GST on sales
• 1B GST on purchases.

If you have luxury car tax, fuel tax or wine equalisation tax obligations you will need to complete additional labels.

You can read more about the Full reporting method on the ATO website.
