Taxes & Accounting in Bilbao
Basque Country
Bilbao is the one city on this list where you do not file with the Agencia Tributaria at all. Under the Concierto Económico (Ley 12/2002) the Diputación Foral de Bizkaia collects and administers most taxes itself — personal income tax and corporate tax included — with its own forms, its own filing portal and its own deadlines, which do not always match the state calendar.
The practical effect is that a competent mainland accountant is not automatically a competent accountant for you. Deductions, incentives and filing mechanics differ, tax-compliance certificates come from the foral administration rather than the state, and the software many firms use is built for the state system. This is a case where the adviser has to be local, not merely Spanish.

Questions about this service
My accountant is in Madrid. Can they handle my Bizkaia return?
Only if they actually work with the foral system, which most Madrid firms do not. It is not a question of competence but of a different administration: different forms, a different portal, different deductions. Ask directly whether they file to the Diputación Foral de Bizkaia — the answer is usually no.
Is the Beckham Law available in the Basque Country?
This is exactly the kind of question that needs a foral-system specialist rather than a general answer, because the special regimes for inbound workers do not map one-to-one between the state and the foral territories. Anyone who answers it instantly without asking where you will be filing is guessing.
