Spain is a very popular destination for meetings and for good reason. Spain has beautiful cities, friendly people and warm weather. The tax laws are, however, more complex than other EU countries:
1. Registration requires various documents to be certified by either an Apostille or by the local Spanish consulate. This can usually take a few weeks.
2. Refunds are technically not possible for non-established entities. This means that care must be given to avoid a refund position when the activities have ceased.
In short, it's very important to be able to reply on a reputable and knowledgeable firm in Spain (a local agent is mandatory). This will avoid a headache down the road.
