I have recorded an expense with GST but in Banking it has matched the expense but says it is Out of Scope???

It's nice to see you here, @MM7857,

To make sure you're able to match the bank transaction accurately, make sure it is categorized with the right GST code. To update it, follow the steps below:

1. Click the bank entry then select Categorise.
2. In the GST field, choose the correct code that is similar to the expense in QuickBooks.
   
3. Once done, go back to the Find match option. The correct code should show this time.
4. To complete the action, click on Match.
