Connect a settlement or credit to the Australian GST adjustment note

A customer and supplier agree to reduce an invoice after a delivery dispute. Before changing the next activity statement, establish whether the agreement changes the consideration for the original supply, corrects an invoice that was wrong from the start, or deals with another obligation. A settlement amount alone does not answer that question.

The ATO distinguishes a later GST adjustment from an error in an earlier return. Retrieve the original contract, invoice, tax treatment and reporting period, then place the signed settlement or credit agreement beside them. Ask the tax reviewer to identify the event and its effective date. Keep compensation, interest and legal costs separately described rather than assuming every settlement component follows the invoice's GST treatment.

Build a short calculation showing original consideration, revised consideration and the difference, with the corresponding GST amounts. State which party supplied what and whether the original treatment remains appropriate. An unexplained credit entered against a customer balance leaves the tax reviewer guessing about the underlying change.

For a hypothetical wholly taxable supply at 10% GST, a price reduction of A$550 including GST contains A$50 of GST. The A$550 receivable adjustment and A$50 tax component serve different purposes in the reconciliation. This arithmetic assumes the settlement is an agreed reduction in that taxable price; it does not determine the treatment of damages or another separately identified payment.

GSTR 2013/2 explains the information an adjustment note must convey, including the issuer, the adjustment's effect and relevant price and GST information. Check that the reader can connect it to the affected supply and understand the change. A document headed credit note is useful only if its content meets the applicable requirements.

Where the supplier's issue obligation applies, the ruling generally requires the note within 28 days of the earlier relevant request or awareness of the adjustment. Record those dates separately. If the original and later events involve multiple invoices, retain an allocation that makes each invoice's reduction traceable without treating the settlement total as a second credit.

A decreasing adjustment generally requires a held adjustment note, subject to exceptions. The A$75 exception concerns the decreasing adjustment amount, not simply the face value of a credit. Increasing adjustments, same-period events and bad debts have different considerations; the ruling specifically distinguishes a bad-debt write-off from an adjustment event.

Have the reviewer record the applicable rule and period. Neither issuing the credit nor receiving a refund automatically establishes which activity statement should change. If an adjustment was missed when it belonged in an earlier period, obtain advice on the correction route rather than relabeling it as a new current-period event.

Retain the final agreement, original invoice, valid note, calculation and approved reporting treatment as one linked file. Reconcile the credit or refund to the customer or supplier account and identify the tax posting separately. If a revised note replaces an incorrect one, preserve the history and confirm that only the accepted adjustment remains in the return workpaper.
