There are actually two options on how to add taxes to your sales:
- The first option, you can simply include the tax percentage in your overall offer price. If you sell to different states/countries, you can always create multiple offers with the respectable tax % and attach each offer to the sales page. Just make sure to include the state/country name within each offer.
- The second option, you can integrate your Stripe account with Quaderno. Here is Quaderno's link which will help get you started if you decide to go this route: Quaderno/Stripe
