Our Other Business Services

We support companies, shareholders, directors and investors with the practical procedures required to function in Spain. The work starts by identifying the documents, registrations and authorisations needed for your specific situation.

Finally, we coordinate the sequence of steps with your legal, tax and accounting work. Our team provides a single point of contact, helping you avoid fragmented communication and complete administrative procedures efficiently.

EFFECTIVE SUPPORT AND PLANNING

What Does the Service Include?

NIE, NIF and Registration Procedures

We assist foreign individuals, shareholders and companies with the identification numbers required to operate in Spain. We prepare documentation, coordinate appointments or representative procedures and help avoid delays in banking, tax or notarial processes.

Digital Certificates and Mailboxes

We support the application and activation of digital certificates for companies and representatives. These certificates are essential for many online interactions with tax authorities, Social Security and other public administrations through their electronic mailboxes.

Bank Accounts

We coordinate business bank account openings, documentation requests, powers of attorney and operational activation where possible. We help clients understand the required sequence and prepare the information banks normally request from foreign owners or directors.

Real Estate Operations

For investors and companies alike, buying, renting or selling real estate is part of their business. We provide clear, reliable legal guidance, from due diligence, contract review to closings and dispute resolution. We ensure every step is handled with professional guidance and security.

FREQUENTLY aSKED QUESTION

Other Business Services in Spain

What is the difference between a NIE and a NIF, and which does my company need?

A NIE (Número de Identidad de Extranjero) is the tax identification number assigned to foreign individuals — required for shareholders, directors and representatives who are non-Spanish residents. A NIF (Número de Identificación Fiscal) is the tax identification number assigned to legal entities — this is what the Spanish company itself receives upon incorporation. Both are needed for most banking, notarial and tax procedures. We apply for NIE and NIF numbers as part of our company formation and corporate support services.

A digital certificate is an encrypted electronic credential that allows a company — or its authorised representative — to interact with Spanish public authorities online. It is required to file tax returns, respond to notifications from the tax agency and Social Security, access the company’s electronic mailbox (DEHU) and complete many administrative procedures that cannot be done otherwise. Accompany is an authorised entity for the issuance of digital certificates and manages the process remotely, with validity of between two and five years for corporate certificates.

DEHU (Dirección Electrónica Habilitada Única) is the centralised electronic notification system used by Spanish authorities — including the tax agency, Social Security and other public bodies — to communicate with companies. Registration is mandatory for all Spanish companies. Notifications sent through DEHU are considered legally received even if unread, and failure to respond within the stated deadlines can result in fines, surcharges or enforcement actions. We register companies in DEHU, monitor incoming notifications daily and manage all responses on behalf of our clients.

It is possible in some cases, but Spanish banks apply strict due diligence requirements to foreign-owned companies, particularly those with non-resident shareholders or directors. The required documentation, the sequence of steps and the likelihood of remote approval vary significantly between banks. We coordinate the process — preparing the required documentation, identifying the most appropriate bank for the company’s profile and managing the interactions — to avoid delays and rejected applications.

Every company incorporated in Spain must have a registered physical address in Spain. For companies that do not have or need a physical office, we offer a business address domiciliation service — registering the company at our address and receiving official correspondence and visits on the company’s behalf. This is a practical solution for international companies operating in Spain without a local office, and ensures compliance with the legal address requirement from day one.

With an appropriately drafted power of attorney, we can act as representative of the company before tax authorities, Social Security, notaries, the Trade Register and other public bodies. This covers filing declarations, responding to inspections, signing documents, completing registrations and managing administrative procedures — without requiring the company’s directors to be physically present in Spain. We draft, notarise and use powers of attorney as part of our standard corporate support service.

Yes. For companies buying, renting or selling real estate in Spain, we provide administrative and legal coordination — including due diligence on the property, contract review, tax compliance on the transaction and coordination with notaries and registries. For companies that already own property in Spain, we also provide property management services. If your company is considering a real estate operation, contact us before committing — the tax and legal implications vary significantly depending on the structure and type of transaction.

Accompany supported me in founding my S.L. and took great care of my administration from the moment I moved to Spain. A great support when you don’t know where to start and how to do your administration in Spain. Their online portal is very useful as well, making administration easier and giving real time insight with the connections with my bank accounts and credit cards. I can totally recommend!
