1. PayPal offers no ability to add tax value into subscription payments, so don't break down things we don't add it as well. Hopefully, it is not a problem for most customers because subscriptions are usually are not subject for tax. I'm sorry if that is a problem for your setup. So, as said, if you need tax calculations for subscriptions, you can use non-recurring PayPal payments. No horror here, as your words may look like. We of course, are constantly working to make our product better, and I hope we will find a clear solution to this problem. 2. Coupons are working well with paypal subscriptions, but it will give discounts only for first payment. If I'm wrong, please let me know in the helpdesk. 3. © £ ?
