Three words, not one job

A gestor administrativo is a regulated profession. Its statute describes professionals who handle, for a fee, procedures before public administrations "que no requieran la aplicación de la técnica jurídica reservada a la abogacía". In plain English: paperwork with the authorities, not legal argument.

A lawyer (abogado) gives legal advice and defends your rights. The lawyers' statute describes the work as advice, counsel and defence of rights and interests through the application of legal science and technique.

Asesor fiscal (tax adviser) and gestoría are words you will see on shopfronts, websites and apps. The general tax law says a taxpayer may act through a representative, "que podrá ser un asesor fiscal", but we found no official source that defines the term or says who may use it. Treat it as a description of a service, not proof of a qualification, and check the person behind it instead.

How to check one is registered

Gestor administrativo

The statute says that belonging to the Colegio for the gestor's main professional address is "requisito indispensable para el ejercicio de la profesión", and that this lets them work across Spain. It also requires gestores to carry professional liability insurance. The national council says anyone who wants to confirm a gestor's registration can contact the relevant Colegio. Ask for the gestor's full name and main office address, then ask the Colegio to confirm.

The statute also says a gestor's office name must carry the gestor's own name and surnames, next to the words gestoría administrativa or gestor administrativo. A brand name with no person behind it is a prompt to ask who the registered individual is.

Lawyer

The Consejo General de la Abogacía builds a national census of practising lawyers from the lists each Colegio sends, and the statute says it is published on the web and on the profession's single window. It lists name, registration number, professional address and whether the person is currently authorised to practise. A lawyer giving advice online must tell you who they are and which Colegio they belong to before asking for payment.

Everyone else

For a person or an app that is neither, there is no register to check. That does not make them bad, but you cannot verify a title that does not exist. Judge them on the written terms below.

What you sign when someone files for you

The general tax law lets you act through a representative, who is then the person the tax office deals with unless you say otherwise. It also says that for things like appeals, refunds or taking on obligations in your name, the representation must be proven.

The Agencia Tributaria describes two routes. One is colaboración social, where an authorised third party files online. The AEAT says that representation covers only that online filing, and does not make them your representative for other acts or for receiving all of the AEAT's communications. The other is the Registro de apoderamientos, where you register a power for specific online procedures, to one or several people or firms. You can revoke a power at any time, but the AEAT says the revocation takes effect only once it is formally communicated to it.

For Social Security, an adviser acts through Sistema RED. Authorisation is required, and it is granted to professionals and firms who submit contribution documents on behalf of others.

The law names you as the obligado tributario, the person who owes the obligations (LGT art. 35). Our reading, as practical advice: a representative can file for you, but the duty stays yours, so keep your own copies and read what is filed.

Which one do you need

  • Registrations, forms, filings, certificates with Social Security, the tax office or other offices: a gestor or an accountant can usually do this. You may also do it yourself, or through anyone you appoint. Spanish procedure law lets people act before administrations through a representative.
  • Tax planning, a first-year return, or a regime choice: an accountant or tax adviser. See your first year as a tax resident and digital nomad tax residency.
  • A refusal, a dispute, or anything going to court: a lawyer. In the contentious-administrative courts the parties are assisted by a lawyer, and before collegiate courts they must also appoint a procurador. Immigration refusals and similar disputes fall here.
  • Advice on rights, contracts or family situations: a lawyer. A gestor is not meant to supply the legal reasoning.

When to hire

Before the step you cannot easily undo. If you are about to register as self-employed, talk to someone first: see becoming an autónomo after the digital nomad visa, and keep the deadlines in view. The same goes for your visa renewal, for bringing family, and for the first return after you become resident.

A checklist before you sign (practical advice)

  • Get the scope and the price in writing. Lawyers must give an engagement sheet (hoja de encargo) or equivalent, preferably in writing, and their fees are freely agreed with the client. Fees vary a lot, so do not rely on a number from a blog.
  • Ask who files what, and by which date.
  • Ask for a copy and the filing receipt of everything submitted in your name.
  • Ask exactly which power you are signing and for which procedures.
  • Ask how you end the arrangement and how the power is revoked.
  • Ask for the registered name and Colegio and confirm it yourself.
