Adjust the GST amount on paid transactions

If a paid invoice, bill or credit note has an incorrect GST amount, there are 4 ways to resolve this. Changing the tax amount on a paid invoice, bill or credit note can have tax implications for you and your customer or supplier. Consult with your accountant or bookkeeper to make sure you use the right method for your organisation.

Delete the payment, edit the transaction, then reapply the payment

  1. Remove the payment using Remove & Redo.
  2. Edit the GST.
  3. Make a new invoice or bill payment, or cash refund on a credit note.
  4. For invoices and sales credit notes, you may need to reissue the invoice or credit note to your customer.

Remove the payment, void and copy the original transaction, then re-enter it correctly

  1. Remove the payment using Remove & Redo.
  2. Void the invoice, bill, or credit note.
  3. Create a copy of the invoice, bill, or credit note.
  4. Complete your new invoice, bill or credit note. You can edit any of the fields.
  5. For invoices and sales credit notes, issue the new invoice or credit note to your customer.

Create a manual journal adjustment

If you need to adjust multiple transactions it may be easier to do it using a manual journal.

We recommend you talk to your accountant or bookkeeper before creating a manual journal adjustment.

Worked example

A cleaning contractor provides cleaning services to your business. She issues bills totalling 5,000.00 (including 652.17 GST). You later find out, after entering and reconciling all the payable invoices in Xero, that she is not registered for GST.

Post a correcting journal:

  • The original transactions total 5,000.00 (4,347.83 coded to Cleaning and 652.17 coded to GST).

  • You need to reduce GST by 652.17 and increase Cleaning by the same amount.

    Image showing GST adjustment journal example

  • The first line of the journal reverses the invoices and their incorrect GST treatment.

  • The second line of the journal correctly reflects the transactions with no GST applied.
