Stripe: Apply tax based on address does not include the tax value in the total amount.

When I try to charge tax in only my state, it doesn't show tax on the form total. I've selected the "use address as billing" but nothing seems to work. Also, I am using Chrome, and the JOtform page doesn't work 100%. When I select some options, they don't save when I close out the STripe integration options.

I have checked your form and I can see it is working fine, but do note that the state should be added as you've specified in the payment wizard, if there is an space before or after the string value then it will not be recognized. 

Here is a screen-cast of my test: 

Please try adding the state without spaces before nor after and it should apply the tax value. 

Regarding to the payment integration not saving, could you please provide us more details? 

I have cloned your form and tested it on my end, so far it works fine, it saves the prices that I have tested and applied the pricing based on quantity and other settings that you have in your payment integration. 

Please let us know, we will wait for your response.
