Company Formation & Banking in Bilbao
Basque Country
A company in Bilbao pays its corporate tax to the Diputación Foral de Bizkaia, not the Agencia Tributaria. Under the Concierto Económico the province runs its own corporate tax with its own rules, incentives and filing calendar, so the tax planning around an incorporation here is a different exercise from the one done anywhere else in this list except the Canaries.
The formation mechanics — notary, deed, Registro Mercantil de Bizkaia — follow the national pattern. What does not transfer is the accounting and tax layer around them. An advisor who has only worked with the state system will file to the wrong administration or miss foral-specific reliefs, and neither error is obvious until a deadline has passed.
Local context: Bilbao
| Extranjería office | Oficina de Extranjería de Bizkaia, in Bilbao |
|---|---|
| Tax filings | To the Diputación Foral de Bizkaia, not the Agencia Tributaria |
| Company registry | Registro Mercantil de Bizkaia |
| Local context | An industrial and services economy with strong public services, attracting employed professionals rather than the sun-belt retiree profile |
| Tax administration | Not the Agencia Tributaria. Under the Concierto Económico (Ley 12/2002) the province collects and administers most taxes itself, with its own forms, deadlines and filing portal |
| Why it matters | A mainland accountant's templates and calendar do not transfer here; income tax and company tax are filed to the foral administration |
| Work authorisation | Granted by the central Oficina de Extranjería |
| Forms and notices | Often bilingual Basque/Spanish |

Questions about this service
Are corporate tax incentives different in Bizkaia?
Yes — the foral corporate tax has its own reliefs, including in areas like research and investment, and they do not map one-to-one onto the state ones. This is a genuine reason to take advice locally rather than to assume a national answer applies.
Can I run a Bizkaia company with an accountant elsewhere in Spain?
Only if they work with the foral system. Most do not, and the gap shows up as filings sent to the wrong administration or reliefs never claimed. Ask the direct question — do you file to the Diputación Foral de Bizkaia — before you engage anyone.
