We are seeing the letter T after taxable amounts per line on our Invoice previews and print outs within QuickBooks. It is confusing our customers.
This is a feature of the QuickBooks software itself, and not at all related to Avalara Avatax.
The letter T will follow taxable line item amounts on printouts and previews for invoices regardless of if our integration is installed.
Per QuickBooks Support in this thread this will not be removed from QuickBooks by Intuit.
It would be possible to include a message on invoice templates that explain the T's place on your invoices.
