What this site is
An independent information site about Modelo 390, Spain's yearly VAT summary return. It is not affiliated with the Agencia Tributaria or any other public body, and we are not a law firm or an accountant. Its information is general, checked against the official sources cited under each section, and no substitute for a professional's advice on your case.
Filing Modelo 390 is free, and you can do it yourself on the Agencia Tributaria's online office (Sede electrónica).
