I'm going to make a suggestion to make this even better. Instead of adding the tax to payments, allow us to add payment forms to the calendars. You can currently add a custom form to a calendar, but when you try to add a product or a payment, it doesn't appear.

This would add so much more flexibility to calendars, instead of setting up individual payments and worrying about tax, it would all be done through a product - allowing for all the functionality.

I've chatted with support and it's not available right now, but would love for this to be available.

I find the added payment to calendars basically useless because there is no tax, and the expectation is to add the tax using stripe which has a monthly subscription fee.

This feature would be great !!
