Héctor Bominaar
Tax & Administrative Adviser · Alicante
About Héctor
A Dutch adviser in Alicante, familiar with the Spanish tax and administrative landscape since 2002.
I am Héctor Bominaar, Dutch by birth and living and working in Alicante since 2002. For twenty years at Dextra Asesores I advised foreign nationals on their tax and legal affairs in Spain. I then practised as a tax adviser at NMN Abogados in El Campello. I speak Dutch, English, German, Spanish and French — so you can always be advised in your own language.
I have now set up my own practice: tax and administrative services for expats in Spain, resident or non-resident, and for the self-employed. Fully digital, so available across Spain and from abroad.
“No intermediaries — you always deal directly with me.”
