We are moving from PayPal to Stripe (finally).
The client has currently got GST set up somewhere within PayPal, so that any purchases from within Australia will have a 10% GST included in the subscription cost. I'm not exactly sure of the setup but was told I didn't need to worry about s2M's taxation because it was handled within PayPal. Now with Stripe,
E.g. if a user in AU purchases a $29 subscription, they will in reality be paying $26.36 + $2.64 GST. If a user anywhere else purchases a $29 subscription, they will be paying $29.
Now with Stripe I've been tasked with sorting out the GST in the same way. s2M has the country-specific tax rates (great) but it's added to the listed cost rather than being included in the listed cost. Stripe Orders API seems the same.
So, looking for advice on how I could achieve the same setup: tax is included for AU payments, zero tax for anyone else, but the total is always constant for both.
