Bill or invoice hasn't been paid
From your dashboard:
- Click on the three little dots top-right of the bank account block and select 'Account Transactions'
- Find your transaction in the list - use the Search function to narrow down the entries if needed
- Click on the transaction, and from the 'Options' towards the top, select 'Edit' and update the Tax Code
- Click on 'Save', and you're sorted
Adjusting the GST rate on a paid invoice or bill is a little trickier
- On your dashboard, click on the three little dots top-right of the bank account block and select 'Account Transactions'
- Find your transaction in the list - use the Search function (top-right) to narrow down the entries if needed
- Click on the box to the left of the transaction
- Just above those boxes, you'll see a button to 'Remove & Redo' - click on that*
- You'll be asked to confirm
- Now that it's unreconciled, you can go into the invoice or bill and adjust the GST rate.
- The transaction going through the bank account still needs to be reconciled (we unreconciled it in step 4). Reconcile the transaction as normal by matching to the appropriate invoice.
* Remove & Redo won't remove the line item from Xero or your bank statement. It's just unreconciling the transaction so you can start again.
