Taxes are not fun but they need to be handled. Stripe & Servicebot can make it easier for you, following are the steps to collect Taxes.
The first thing you need to do is to create a Tax Rate in Stripe. That can be done here. Once you have a tax rate created, you can grab the ID of it, it would look like 'txr_1Gv6cMHSBbxioZ9IxeKTDxSo'.
This value will be used to pass in the tax rate to the Servicebot embed snippet. It will be added to the window setting in an option called 'default_tax_rates'. Setting this on your Plan Picker, Pricing Page, or Checkout form will add the tax rate to your subscription.
