Reporting - Add a GST Summary Tab to the Activity Statement
Include an extra tab that summarises the totals for the Tax Rates including the cents.
This will eliminate the need to scroll through all the detail to code the journal/payment.

Hi team, I know it's been sometime since this idea was originally raised and we wanted to provide an update for you all here.
Xero's Activity Statement report today has two tabs - Summary and Transactions.
The Summary tab summarises the Tax Rates totals of all transactions. This shows a round number without cents in line with ATO. Transactions tab includes all transactions associated with the Activity Statement period.
You can find more detail about how Xero populates the Activity Statement on Xero Central.
