**Boris**Hello Elzimar.

Regarding form calculations, I would advise you to take a look at the following guides:

http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form

To add a calculation of tax, we could simply add a Form Calculation field, and set it to count, for example, 8% of the plain price of a product.

I have made a demo of the form here: http://form.jotformpro.com/form/51554615696969 (you can clone it to take a closer look.)

Please let us know if we can assist you further.
