Unfortunately that's almost correct. See, if you sell to a Spanish citizen you now are unable to opt-out of VAT, because Spain does not have such a minimum. The whole VAT/sales tax situation in the EU is incredibly complex and it's little issues like the one you missed that can completely mess up your otherwise orderly run company.
*Resident of Spain, not Spanish citizen. Big difference. With the exception of the residents of Canary Islands, Ceuta, Mellila, which are part of Spain and the EU, but not part of the EU VAT area.
There is so much nonsense with the new VAT regulation and so much internal contradiction that I'll be surprised if it won't explode within a year or so.
