Sales Tax added to service

[CarolynMcGee]

Hi,  

I have PayPal set up as payment option from my external sales form (using Kartra). 

The item is a service which is non taxable in MA.  I have it set up as non taxable in the form.   

When it goes to PayPal they are adding tax.   How do I change this?

Thank you,

Carolyn
