I have an application that will charge users a small fee on a monthly basis, but the amount is VAT-able. VAT is changing in January from 17.5% to 20%.
How does Paypal handle this? I can see in the API that you should pass the Tax Amount https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_nvp_r_CreateRecurringPayments
Does this mean we have to update every recurring payment on behalf of the customers in Jan?
