Hi Somm-Wine-Admin , this workaround is only an idea of mine atm, and it depends how your file and GST codes are set up.
I would consider setting up a separate account for this new GST code, which I presume would apply to income, and would therefore collect credits.
So then each month I would transfer out of that account (by GL journal) the appropriate portion to accounts for each of the component GST codes, leaving a nil balance each month. The simplest journals would only use N-T codes, and therefore the credits on that journal would be the 'GST on income' figures for your GST reports, plus any other GST on non-Shopify transactions.
Our biggest concern is tax compliance as we only issue invoices to our customer from MYOB. We do not send invoices or do any accounting in Shopify as payments are only done on accounts on MYOB. I don't know if there is any work around for that.
