Action Required: Review tax for transactions created or modified on the Banking page on 3 October 2025

On Friday, October 3, 2025, between 11:00 AM and 8:30 PM AEST, a system issue may have impacted tax calculations on transactions.

While the issue has been resolved, if you posted transactions from your bank feed, mobile or synced transactions from a third-party application during this window, tax may not have been calculated correctly. Please note that bank-to-bank transfers (e.g., Monzo to Barclays, or transfers between a business account and a savings account) and other non-taxed transactions were unaffected.
