#1 Form setup You have created your form in Google Forms. You have used multiple choice questions for items with prices. While this will work for amount calculations, I'd recommend you to convert fields into products so that you can allow users to select multiple items and also more than one quantity for an item. There are two options. (1) You can use the Neartail templates to create your form (2) When you customize the form using the Neartail addon, convert fields (items with prices) into products and then add amount, tax, delivery, next amount calculations. #2 Tax calculations There are two options to calculate taxes. (1) setup taxes for each product and the use the standard TAX() formula to calculate the taxes (2) calculate the tax as a fixed percentage of order amount. Setup tax for product Login to Neartail > click on the form to open it > Edit page will be displayed > In the Edit page, click on the gear icon next to the product > update the tax percentage and click Save. Repeat the steps to set up the tax percentage for each product where applicable.
