Three owners in the communities we administer asked the same question this summer. A German couple in Corralejo had been told by a neighbour that every foreign owner needs a «representante fiscal» in Spain. A British owner in Caleta de Fuste had received nothing from the tax office for two years and wondered where the letters were going. A Dutch owner who lets her flat through an agency wanted to know whether the agency was «responsible» for her tax. The three questions have three different answers, and all of them sit in two laws: the non-resident income tax law, which says who must appoint a representative and where a non-resident's tax address is, and the General Tax Law, which says who may act for you and what happens when a letter reaches a flat with nobody in it. This piece sets out both, as they stand in September 2026, and what a community administrator can and cannot do about them. Quotations are in Spanish with the reading in English.
Who must appoint one: the article 10 list
The obligation lives in article 10 of the non-resident income tax law, the Real Decreto Legislativo 5/2004, in the wording the Ley 11/2021 gave it. It starts by excluding most of our owners:
«Los contribuyentes por este Impuesto que no sean residentes en otro Estado miembro de la Unión Europea estarán obligados a nombrar, antes del fin del plazo de declaración de la renta obtenida en España, una persona física o jurídica con residencia en España, para que les represente ante la Administración Tributaria» — taxpayers who are not resident in another EU member state must appoint, before the end of the filing period for the income obtained in Spain, a person or company resident in Spain to represent them before the tax administration (art. 10.1).
So an owner resident in Germany, the Netherlands, Italy or France has no duty to appoint anyone; nor has an owner in Norway or Iceland, because the same article extends the exception to the European Economic Area states that exchange tax information with Spain. Since 2021 those owners deal with the tax office «por medio de las personas que ostenten su representación de acuerdo con las normas de representación legal y voluntaria» — through whoever represents them under the ordinary rules of the General Tax Law (art. 10.2), which is the voluntary representative of the next section, or nobody.
For everyone else — a British, Swiss, American or Emirati owner — the duty exists in four cases: when they operate through a permanent establishment; when they carry on an economic activity in Spain without one, in the cases of article 24.2; when they are an entity in the income-attribution regime of article 38; and «cuando, debido a la cuantía y características de la renta obtenida o a la posesión de un bien inmueble en territorio español, así lo requiera la Administración Tributaria» — when, because of the amount and nature of the income or the ownership of a property in Spain, the tax administration requires it. An owner of a flat in Caleta de Fuste who lives in Manchester is not obliged to appoint a representative by the mere fact of owning it; the obligation arises the day the tax office asks, and the clock is then the filing deadline of the income concerned. A fifth case is automatic: residents of the jurisdictions Spain lists as non-cooperative, who own assets or rights in Spain, must appoint one whatever the income.
The appointment has a form and a deadline of its own: the taxpayer or the representative must notify it, «debidamente acreditado, en el plazo de dos meses a partir de la fecha de éste» — duly evidenced, within two months of the appointment — to the tax office where the return is filed, and «a la comunicación acompañará la expresa aceptación del representante» — the notice must carry the representative's express acceptance. Failing to appoint one when the duty exists «se considerará infracción tributaria grave, y la sanción consistirá en multa pecuniaria fija de 2.000 euros» — is a serious infringement fined at a fixed 2,000 euros, 6,000 for residents of non-cooperative jurisdictions, reduced by 40 % if paid promptly without appeal (art. 10.4, with article 188.3 of the General Tax Law). And where the duty is breached, the law lets the tax office pick a representative for you: for a permanent establishment, whoever appears in the Companies Register; for residents of non-cooperative jurisdictions, «el depositario o gestor de los bienes o derechos» — the depositary or manager of the assets (art. 10.3).
Who may appoint one: the voluntary representative
Not being obliged does not mean not being able. Article 46 of the General Tax Law lets any taxpayer «actuar por medio de representante, que podrá ser un asesor fiscal, con el que se entenderán las sucesivas actuaciones administrativas» — act through a representative, who may be a tax adviser, with whom the administration will then deal (art. 46.1). For routine steps the representation is presumed; for appeals, waivers, refund claims and anything that needs the taxpayer's signature it must be proved «por cualquier medio válido en Derecho que deje constancia fidedigna» — by any means that leaves reliable evidence — or by appearing in person, and the tax office's own standard forms of representation are valid for that (art. 46.2). Advisers who file returns for clients do so under the collaboration agreements of article 46.4, and the tax office can ask for the power at any time.
For an individual owner abroad the practical vehicle is the census form, the Modelo 030, on which a non-resident natural person records or changes a representative and a tax address in Spain; the tax office's own page on non-resident representation points to it. The representative can be a relative with a home on the island, a lawyer, an adviser or a company — the law asks for residence in Spain and, for the compulsory case, for an express acceptance, nothing more. What the appointment changes is the next section: where the letters go.
Where your letters go: the tax address of a non-resident
A non-resident owner has a tax address in Spain whether or not they chose one. Article 11 of the non-resident law fixes it:
«Cuando obtengan rentas derivadas de bienes inmuebles, en el domicilio fiscal del representante y, en su defecto, en el lugar de situación del inmueble correspondiente» — for income from real estate, at the representative's tax address and, failing one, at the place where the property is situated (art. 11.1.b).
For any other income it is the representative's address or, failing that, the address of the person solidarily liable for the tax (art. 11.1.c); and where no representative was appointed, «las notificaciones practicadas en el domicilio fiscal del responsable solidario tendrán el mismo valor y producirán iguales efectos que si se hubieran practicado directamente al contribuyente» — notifications made at the address of the person solidarily liable are as valid as if made to the taxpayer (art. 11.2). For residents of non-cooperative jurisdictions with neither, a notice left at any of their properties counts.
Read that against the calendar of an owner who visits twice a year. The British owner in Caleta de Fuste who never appointed anyone has, in law, his tax address at his own flat. The tax office's letters go there. A change of tax address «no producirá efectos frente a la Administración tributaria hasta que se cumpla con dicho deber de comunicación» — has no effect on the administration until it is communicated (General Tax Law, art. 48.3), so a new home address in England, however well known to the community, changes nothing at the tax office until the census form says so.
What happens at the door
The General Tax Law then describes, step by step, how a letter to an empty flat becomes a notification. In procedures the tax office opens on its own initiative, the notification «podrá practicarse en el domicilio fiscal del obligado tributario o su representante, en el centro de trabajo, en el lugar donde se desarrolle la actividad económica o en cualquier otro adecuado a tal fin» — may be made at the taxpayer's or the representative's tax address, at the workplace, where the activity is carried on or at any other suitable place (art. 110.2). If you are not there, «podrá hacerse cargo de la misma cualquier persona que se encuentre en dicho lugar o domicilio y haga constar su identidad, así como los empleados de la comunidad de vecinos o de propietarios» — anyone present who identifies themselves may take it, and so may the employees of the community of owners (art. 111.1). A concierge who signs for the postman has, in law, received your notification; refusing it counts as receiving it (art. 111.2).
When nobody signs, article 112 takes over: after two attempts at the tax address — one is enough if the addressee is recorded as unknown there — the tax office summons you by a notice published once in the Boletín Oficial del Estado, on a Monday, Wednesday or Friday, which may also be displayed at its office and, «en el caso de que el último domicilio conocido radicara en el extranjero», at the consulate. You have fifteen calendar days from the day after publication to appear; «transcurrido dicho plazo sin comparecer, la notificación se entenderá producida a todos los efectos legales» — after that the notification is deemed made for all legal purposes (art. 112.2). From then on the procedure continues without you until the assessment and the order to seize assets, which are notified again the same way. That is the chain we described from the other end in our piece on the frozen bank account: the owner learns of a tax debt when the card is declined, months after a letter was left with a neighbour.
Electronic notification does not remove the problem; it moves it. Companies are obliged to receive tax notices electronically; individuals may opt in, and a notice placed in the electronic mailbox is deemed delivered ten calendar days later whether or not it is opened, as our colleagues explain in their piece on Hacienda's electronic notifications. For an owner abroad it is the better problem to have — an e-mail alert reaches Manchester, a postman does not — provided someone checks the mailbox.
What the administrator can and cannot be
Owners often assume that the community's administrator receives their tax letters and will forward them. The law is clear, and it is not that. The administrator of your community is the community's administrator: the tax office knows nothing of them in relation to your income tax, and a letter addressed to you at the flat is delivered to the flat, not to our office. What the law does allow is that the community's staff sign for it, with the effect just described. In the communities we administer with a concierge or a maintenance employee, the staff are instructed to record every registered letter and to tell us the same day, and we tell the owner — but the fifteen-day and ten-day clocks run from the delivery, not from our e-mail.
An administrator, or the firm behind one, can be appointed as your representative, because the law asks only for a person or company resident in Spain. What that appointment carries is worth stating precisely. It moves your tax address to ours (art. 11.1.b), so the letters come to a desk that is open every working day; it lets us file the return and answer the tax office on your behalf under article 46; and it does not make us liable for your tax: the solidary liability of article 9.4 falls on the representatives of taxpayers with a permanent establishment or in the income-attribution regime, not on the representative of a private owner. The person who is liable is a different one: «el depositario o gestor de los bienes o derechos de los contribuyentes» — the depositary or manager of the taxpayer's assets — answers solidarily for the tax on the income of what they manage, together with the payer of the income, except where withholding applies (art. 9.1). A rental manager who collects your rents, an agency that holds your keys and your bookings, is inside that rule; the tax office needs a formal act deriving the liability before it can collect from them (art. 9.3), and it can file and pay the return in your place (art. 28.2). Our rental administration service files the Modelo 210 for the owners whose lets we manage for exactly that reason.
The return and the calendar
The rules above decide where a letter arrives; the return decides whether one is written at all. Every non-resident owner files the Modelo 210: on the imputed income of a flat that is not let, and on the rent of one that is, at the rates and in the windows we set out in our piece on the obligations of a non-resident owner — the 2025 imputed-income return is due by 31 December 2026, and from the 2026 tax year the windows change. The return identifies the representative where there is one and, for an owner who appointed none, the tax office's data on the property are what generate the checks: a flat that appears in the cadastre with a non-resident owner and no return is the simplest mismatch in the system, and the letter it produces goes to the address of article 11.
A power of attorney is not a tax representation and does not replace it. The notarial power we described for owners abroad lets an attorney sign, sell, vote and deal with banks and utilities; the tax representative is a distinct figure with its own form, and an attorney who is also named as representative on the census form covers both. For the community's own notices — the convocation of the junta, the minutes, the certificates — the Horizontal Property Act asks every owner to give the secretary an address in Spain, failing which the flat is the address for those too (art. 9.1.h); our owners abroad give us an e-mail and a postal address on the day they buy, and the junta papers reach them wherever they are.
Where we come in
For the owners abroad in the communities we administer, and for the owners whose lets we run, the arrangement we recommend is the same: a tax address in Spain that is open every working day, whether ours or a relative's, recorded on the census form; the electronic mailbox where the owner can hold it; the Modelo 210 filed every year in its window; and one person on the island who knows what a registered letter looks like. Where the tax office requires a representative — the British and Swiss owners it writes to, the residents of listed jurisdictions — we act as one, with the express acceptance the law demands and the two-month notice filed. The non-resident owners page describes the service, and a quote takes a day.
Common questions
I am British and own a flat in Caleta de Fuste. Do I have to appoint a fiscal representative?
Not by the fact of owning it. Since 2021 the duty falls only on non-EU residents in four cases — a permanent establishment, an economic activity in Spain, an income-attribution entity, or a requirement from the tax office because of the income or the property — and on residents of the listed non-cooperative jurisdictions. If the tax office requires it, appoint someone resident in Spain before the filing deadline and notify it with their acceptance within two months; the fine for not doing so is a fixed 2,000 euros.
Can my community administrator be my fiscal representative?
Yes, if appointed: the law asks only for a person or company resident in Spain. Without an appointment the administrator is not your representative and does not receive your tax letters; the community's employees may sign for a letter left at the flat, and that counts as delivered to you. A representative of a private owner is not liable for the owner's tax; a manager who collects your rents is, under article 9.1.
Where does the tax office send my letters if I have no representative?
To the property itself, which the law makes your tax address for income from real estate. Two failed attempts there, or one if you are recorded as unknown, lead to a notice in the Boletín Oficial del Estado and, fifteen calendar days later, a notification deemed made. A new address abroad changes nothing until it is communicated on the census form.
Is electronic notification available to a non-resident owner?
Yes, by opting in; companies are on it whether they like it or not. A notice placed in the electronic mailbox is deemed delivered ten calendar days after it is made available, opened or not, so the mailbox needs a person who checks it — or a representative who does.
