Tax 19% with PayPal sign nup

Hi Team,

First of all I will thank you for all the great support you give us.

I hope you can help me out with the following question:
The Support plugins works fine and so also the recurring PayPal payments.

But how can I set up the 19% tax for the invoice?
Now we have an invoice with 0% Tax, but that isn't allowed in Holland..

Thank you in advance!
Stijn
