Notification if a transaction has been posted directly to the GST account, as opposed to the GST transaction being recorded as part of the tax field in a transaction.

There are a couple of legitimate times where posting directly to the GST account is valid - generally at the end of a reporting period to enter the clearing transaction.

Any other post to the GST account could be problematic, as if it relates to a GST adjustment, the Xero Activity Statement will not pick this up as part of the AS automation process.
