Here is what I now know.
If relocating to Spain, having been outside Spain for > 12 months. VAT (IVA) should be waived. The issue I have is that Customs (aduana) are asking for proof by way of a "baja" which is something that Spanish Consuls can issue to Spaniards. The law states that they should be asking for "baja OR other documents which are acceptable in law". It seems I'm just dealing with one or both of a lazy customs officer combined with a customs agent.
I've also learnt that I also need to provide a "padron" and a NIE. Significantly, the NIE must also be registered for tax at the local Oficina de Hacienda, who will issue some stickers "etiquetas fiscales" which need to be attached to the paperwork (DUA).
