Making adjustments in Simpler BAS

What to do if you need to make GST adjustments in your Simpler BAS. You may need to do this if you discover a mistake or a missed transaction, in a finalised activity statement.

Making adjustments when your activity statement hasn’t been lodged with the ATO

If you’ve finalised your activity statement, but haven’t yet lodged it with the ATO, you can revise your activity statement by deleting it. Export your activity statement before you delete it, if you want to keep a record of it.

When you're ready, you can finalise the updated activity statement and lodge with the ATO.

Making adjustments when your activity statement has been lodged with the ATO

You'll need to consider the ATO's guidelines for changing a BAS that's already lodged before choosing which option to use in Xero. Talk to your accountant or bookkeeper if you’re not sure.

Option 1 - Reverse and re-enter the transaction

Delete or void the transaction or changes that you need to adjust, and re-enter dating in the next GST period. Xero will include the adjustment in the activity statement for the next period.

Option 2 - Re-lodge the BAS

Delete and then re-finalise the BAS for the period the changes occurred in. Then lodge an amended BAS with the ATO.

Option 3 - Enter a GST adjustment

Enter a manual journal to record a GST adjustment that appears in the next BAS. We recommend you confirm with your accountant or bookkeeper if you’re unsure how to enter an adjustment.
