How do I eliminate Sales Tax from orders?

Are you referring to your JotForm titled "LMEP Plant Sale Form"? As I check this form, I see that there are no taxes added in the Payment wizard. If you are referring to other form, you may access the Taxes section of the Payment wizard by following the guide.

You may remove the set the base rate as 0 so that the Taxes will not be calculated. 

Hope this information helps! Please get back to us if you need any further assistance. We will be happy to help.
