Check how each advisor is registered, then compare several quotes for your case, which you can do in one place on Expatronus. English decides between the ones that pass. Updated October 2026.
This guide is for anyone in Spain, or about to move, who typed "English-speaking tax advisor" into a search bar and got a page of offices that all say the same thing. By the end you will know what English tells you about a professional, what it leaves out, and how to check the part that matters before the first call.
Is an English-speaking advisor the right advisor?
Most people start their search with the language, and it is easy to see why. Tax is stressful enough in your own language. An advisor who answers your email in English feels like the problem is half solved.
English makes the calls easier and the emails quicker to read. It tells you nothing about whether the person is registered for the work, whether they handle cases like yours, or who in the office will actually prepare your file.
So the useful first question changes. "Do you speak English?" becomes "Are you registered for this work, and do you handle cases like mine?" Language then helps you choose between the advisors who pass.

Who does what: tax advisor, gestor or lawyer?
Here is who usually takes which task. It is a typical split, and an individual office may cover more or less.
- Planning how income from two countries is taxed: tax advisor, yes; gestor, sometimes; lawyer, sometimes (a tax lawyer)
- Filing a routine annual return: tax advisor, yes; gestor, yes; lawyer, rarely
- Registrations and certificates at an office: gestor, yes; tax advisor, sometimes; lawyer, sometimes
- Residence permits and visa paperwork: lawyer, yes; gestor, sometimes; tax advisor, no
- A dispute that goes to court: lawyer, yes; gestor, no; tax advisor, no
- Answering a letter from the Agencia Tributaria: tax advisor, yes; gestor, sometimes; lawyer, sometimes
The tax advisor (asesor fiscal)
An asesor fiscal looks at how your income is taxed: where you are resident, how foreign income is treated, which forms apply. Unlike a lawyer or a gestor administrativo, an asesor fiscal is not tied to one official college. Many belong to a professional association, and some are also lawyers or economists. That makes the question "which body do you belong to?" more useful than any line on the website.
The gestor administrativo
The lawyer (abogado)
How do I check an advisor is registered?
Each profession has its own way to check, and none of them depends on the language the office speaks. Ask for the details in the first email, then look them up yourself.
- Lawyer: the Censo General de Letrados of the Consejo General de la Abogacía lets anyone look up a registered lawyer by name or registration number. Its data comes from the bar associations themselves.
- Gestor administrativo: ask for the provincial college and the registration number, then confirm with that college.
- Tax advisor: ask which professional association they belong to, and whether they file through colaboración social or with a power you sign.
- Sworn translator: the Ministry of Foreign Affairs publishes the official list, with a search tool, covered in the next section.
An office that cannot say how its people are registered leaves you nothing to check.

When does a sworn translator come in?
An advisor who speaks perfect English is still not a sworn translator, and a translation they make of your certificate does not carry that status. Ask your specialist which of your documents an office wants translated, and by whom. Regions with a co-official language keep their own registers for those languages.
Where can I compare English-speaking tax advisors in Spain?
There are several ways in, and each shows you something different before you make contact. For each one below: what you see first, who checks the professional, what it costs you to use, and what it suits.
- Word of mouth: one name and one person's experience; nobody checks registration; nothing to ask; a good start to a shortlist
- Google Maps and reviews: stars, comments and an address; nobody checks registration; free to search; finding offices near you
- Expat directories and forums: listings the firms write themselves, and threads from other movers; checks vary by site, so ask; usually free to read; seeing which names come up often
- Official registers (Censo de Letrados, colleges): registration and office address; the college keeps the data; free; checking a name you already have, though they show no language or price
- General freelancer sites: profiles the freelancer writes; the site's own checks; you pay the freelancer; small tasks with no official side
- Expatronus: estimates from verified, independent specialists for the case you describe; we verify the specialists before they join; you pay the specialist you choose, at their own rates; comparing several on the same case. We are new and growing city by city, so the choice varies by place
How comparing works on Expatronus
The order is the same for every case.
- Describe the case once. The case wizard asks about your move and your situation, so each specialist reads the same details.
- Specialists send estimates. Each interested specialist reviews the case and sends an initial estimate. It is not binding and can change after you talk. Sending the estimate opens a chat.
- Chat and agree the scope. Several specialists can be proposing at this stage, and your contact details are not shared yet. This is where you ask about registration, language and who does the work.
- Receive an offer. The specialist sends an official offer.
- Accept one. The case goes to that specialist and closes to everyone else. From there you can talk on any channel, and you pay the specialist directly at their rates.
What should I compare in a tax advisor's quote?
Two quotes can look alike and cover different work. Line them up on the same points.
- Scope: which returns, which tax years, and whether income from abroad is part of the work
- What is excluded: letters from the tax agency, corrections, a second country's filings
- Who files, and how: through colaboración social or with a power of representation you sign
- Who you speak with: the advisor on your file, or someone passing messages
- Written language: whether the advice you keep comes in English, Spanish or both
- How fees are set out: a fixed fee per filing, a monthly retainer or hourly, and what triggers an extra charge
- Response: how they reach you when something arrives from Hacienda
Red flags when hiring an English-speaking advisor
- The English speaker is not the advisor. A front desk translates for someone you never speak to, and details get lost between them.
- No registration they can name. A lawyer or gestor administrativo can give you a college and a number. A tax advisor can name an association.
- "We handle everything." A scope with no edges is hard to hold anyone to.
- A power broader than the job. A power of representation should match the work you agreed.
- Advice to leave income off a return. Walk away.
- No professional liability insurance. Ask whether they carry it.
Questions to ask in the first call
- How are you registered for this work, and where can I check it?
- How many foreign residents with a case like mine do you work for?
- Who will prepare my file, and can I speak with them directly?
- Do you file for me online, and what do I sign to allow it?
- What is in your fee, and what would cost extra?
- Will I get written advice in English, in Spanish, or both?
- What happens if a letter from the Agencia Tributaria arrives in the middle of the year?
FAQ
Do I need an English-speaking tax advisor in Spain?
It is a preference. Many people sleep better when they can ask questions in their own language, and that is a fair reason to choose. Keep in mind that the forms and the letters stay in Spanish, so the advisor's registration and experience still come first.
Should I hire a gestor or a tax advisor for my return?
Can my advisor translate my documents for an office?
They can help you understand a document, but an official translation between a foreign language and Spanish comes from a sworn translator appointed by the Ministry of Foreign Affairs. Ask the specialist which documents need one.
How do I check a gestor is registered?
Ask for the provincial college and the registration number, then confirm with that college. A registered gestor administrativo will expect the question.
What is the best English-speaking gestor in Madrid?
The best one for you is registered, handles cases like yours, and explains them in words you follow. Ranking lists rarely check the first two. Comparing a few estimates for your own case tells you more than a ranking.
Can a tax advisor file my return without me?
Advisors can submit returns for clients through the tax agency's colaboración social scheme or with a power of representation, and both rest on your prior authorisation. Ask which one they use before you sign anything.
Is an English-speaking lawyer better for a tax question?
Only if tax is their field. Many lawyers keep to one area, so ask what share of their work is tax before you book the call.
