How do you make discounts non taxable on the invoices. not the products and services but down at the bottom before the totals.

Good morning, @mbrickel. 

Welcome to the Community! 

To clarify, can you provide me with a screenshot of the invoice you're referring to? 

In the meantime, you can check out this guide as a future reference: Add a discount to an invoice. 

I'll be waiting for your response!
