Setup GST once in the income and expense items

Is there anyway I could get the software to automatically include the GST in the entries? I rather set it up once for all (maybe in the chart of account) as I tend to forget when doing the journals.

Thank you.

It is not possible yet. Something I’m planning to add. Keep in mind, even you forget to set GST on some transactions, there is “Tax Audit” report you can review which will give you breakdown of all your transactions by tax code.
