How can I make a single line non taxable in QuickBooks Online?

Overview

I'd like a single line of my invoice/estimate to stop calculating tax from Avatax within QuickBooks Online.

Environment

QuickBooks Online

Resolution

• At the invoice and or estimate level each line a taxable checkbox.
• If you do not have the box checked, the item will be non taxable. 
  • Tax Code NT will be sent to Avatax.
• If you have the item mapped in AvaTax, the tax code mapped in there is be used.
  • NT will be overridden by what is in AvaTax. 
• *Note* the tax code NT will not work if you're an SST member and the ship to state for this estimate and or invoice is an SST state.
