Hello Escoces,

I know this answer arrives late, but just in case it may be helpful for anyone, I will post it.

There are no major differences if you are going to set up a branch office in Spain, compared to setting it up in another EU country. However, I recommend you to get correct advice about the fiscal regulations and tax obligations, applied to all companies in Spain. A financial/fiscal advisor will be able to give you the required information, and provide guidance on the tax you would be paying depending on the invoicing volume and projected income you are looking at. The Real Estate business in Spain is one of the hardest hit sectors by the economic crisis however it slowly starts to improve.

Regards,
