Integration QBO.Default tax on costs is a combined one : GST/PSt QC .Secondary tax extraction toggle is ON. An item is marked as billable and product and service is assigned on it. The product and service has a tax rate assigned on it in QBO and it is GST.When we publish the item it appears with two taxes in QBO. That is expected behaviour because of the tax settings.The user, though, is expecting just the GST to be published as the product and service assigned has a GST only on it in QBO.

We are already advised to turn off the secondary tax extraction and leave GST as a Default tax for costs, but we would like to keep the tax settings the way they are at the moment.Thanks.
