Accounting on a cash basis
If you account for GST on a cash basis, include your amounts of GST, GST credits, sales, purchases and importations in the BAS for the reporting period in which you received or provided payment or part payment in relation to those amounts.
These may not be the full amount of the sale or purchase price.
We have information on how to complete your BAS for several less common transaction types that may apply to your circumstances.
Accounting on a non-cash basis (accruals)
If you account for GST on a non-cash (accruals) basis, include amounts of GST, GST credits, sales, purchases and importations in the earlier reporting period in which you have:
- received or provided any of the payment in relation to those amounts
- issued or have been issued with an invoice in relation to those amounts.
We have information on how to complete your BAS for several less common transaction types that may apply to your circumstances.
You claim GST credits on importations in the same reporting period you pay the GST to Department of Home Affairs, unless you are using the deferred GST scheme.
