A tax advisor plans your taxes before you pay them. A gestoría files your paperwork after you have decided what to do. They are not the same service, and most people end up paying for the second while believing they bought the first.
One thing worth knowing before you sign anything: "asesor fiscal" is not a protected title in Spain. No qualification is required, no body licenses it, and none can strike anyone off.
This guide covers what each type of firm does, which titles are regulated, and the questions to ask.
The job is to get ahead of things: to look at your situation before the year closes and tell you what to do differently.
What it is not: taking the invoices you send and filing whatever is there. That is processing. It is a legitimate service, but it is a different one and should cost a different price.
This is the part nobody tells you, and it is the part that matters most.
Gestor administrativo is a regulated profession. It requires a specific qualification and mandatory membership of an official body, with a code of conduct and a regulator that can sanction.
Economista is regulated too. Mandatory membership, code of conduct, and professional indemnity insurance.
Asesor fiscal is not. There is no protected title, no required training, no official exam and no body that can bar anyone from practising. Anyone can legally call themselves a tax advisor in Spain.
The good ones are usually economists, lawyers or chartered accountants registered with a professional body voluntarily. It means the title alone guarantees nothing, so look at what sits behind it.
None of these are awkward for a serious professional.
Working in English is a service, not a given. Ask whether your assigned contact speaks English, not just the sales team.
Ask whether they handle cross-border situations: income from clients abroad, assets in another country, or the Beckham Law regime if you moved to Spain recently. Not every firm does, and those that do not will often not say so upfront.
Everything the tax office sends arrives in Spanish, and deadlines run from the date of notification. Make sure someone on your side reads those notices promptly.
Having this ready turns the onboarding from days into hours.
If you have not registered yet, the process is in how to register as a freelancer in Spain.
Monthly fees for self-employed clients run from around 25 to 100 euros, with continuous tax advice at the upper end or above.
The full breakdown is in gestoría prices for autónomos.
Two warnings about advertised prices. Almost all exclude VAT, so add 21%. And the annual income tax return is usually billed separately from the monthly fee, even when nobody mentions it at signup.
If three or more sound familiar, start by checking whether you are claiming everything in deductible expenses for autónomos.
Ask for your documents before you give notice: invoices, filed returns, receipts and books. Some firms slow down as soon as they know you are leaving.
The right order:
Step three is the one people forget. If you do not revoke it, your old firm keeps receiving your tax notices and you do not.
Do it at the end of a quarter. Switching mid-quarter means pulling data from two firms for the same return.
No. A gestoría files and processes. A tax advisor analyses and plans. Many firms offer both, but the basic monthly fee usually covers only the first.
No. "Asesor fiscal" is not a protected title and there is no mandatory registration. Reputable advisors are usually registered economists, lawyers or chartered accountants, but the law does not require it.
It is not compulsory. You can file everything yourself through the tax office's electronic portal with a digital certificate. It comes down to the cost of your time and the risk of missing deductions.
You can, but everything the tax office sends will be in Spanish, and deadlines run from the notification date. Make sure someone on your side reads those notices promptly.
You are the taxpayer, so the tax office claims the surcharge or penalty from you. You can then pursue the firm, which is where their professional indemnity insurance matters.
Yes. The clean point is the end of a quarter. Request your full history before leaving, and remember to revoke the old firm's authorisation or they will keep receiving your notices.
No. You have to grant that authorisation explicitly, and you can revoke it whenever you want. Without it they cannot receive your notices or act on your behalf.
