Is there a default setting that adds sales tax to all items linked from Faire?

[NikkiNo5]

When I place orders through Faire, I have opted (via Faire) for all items on any orders to link to my Square. I want our sales tax added to all those linked items, but Square does not add it automatically.  I have to manually open each item in Square to add sales tax. I hoped this would be an option on the Bulk Edit feature, but it is not. Is there a process or default setting automatically adding sales tax to every item that integrates/links from Faire?
