Your BAS will report your business revenue to the ATO for the quarter, and any Goods & Services Tax (GST) on both your sales and expenses.
You will either have a GST refund (if GST-related expenses are more than GST-related sales), or a GST payable (if sales exceed GST-related expenses).
Your BAS will also report any employee wages and PAYG withholding tax. The withholding tax will be added into the GST.
By lodging your BAS through a registered tax agent such as POP Business, you will get an additional ONE MONTH to make payments which can be great for helping with your business cashflow.
