The Spanish law that sets the reduced rate for renovation work asks three things of the person paying: that you are an individual, that you are not acting as a business, and that you use the home privately. It does not ask where you live or where you pay tax. That is the whole answer to the question, and it comes from the article itself rather than from an interpretation of it. What does break the reduced rate is using the home as a business, and letting it out is the case to look at closely. What is written for Spanish taxpayers is something else entirely: the income tax deduction for energy works and the national grant programme both attach to a habitual home, and a non resident files a different tax altogether.
The three conditions are about you, about the age of the home, and about how much material the builder supplies. The first one is the one this page exists for, so it gets its own section below. The other two are simple to check.
Que la construcción o rehabilitación de la vivienda a que se refieren las obras haya concluido al menos dos años antes del inicio de estas últimas.Que la persona que realice las obras no aporte materiales para su ejecución o, en el caso de que los aporte, su coste no exceda del 40 por ciento de la base imponible de la operación.The tax authority publishes its own worked example of that material limit, and it is worth reading because it turns on the invoice rather than on the job: the same 10,000 euro job falls either side of the line depending on how much of it is material.
La colocación del suelo de una vivienda por 10.000 €, correspondiendo 3.000 € a materiales aportados por quien realiza la obra, tributa toda ella al tipo reducido.Una obra por un importe total de 10.000 €, si los materiales aportados ascienden a 5.000 €., tributa, sin embargo, al tipo general.Three things, and they are all about what you are and what you use the home for. The article asks for a natural person, who is not acting as a business or professional, and who uses the dwelling for private purposes. It sets no condition about where that person lives or pays tax. The same paragraph adds that a residents association ordering the work is covered too.
Que el destinatario sea persona física, no actúe como empresario o profesional y utilice la vivienda a que se refieren las obras para su uso particular. No obstante lo dispuesto en el párrafo anterior, también se comprenderán en este número las citadas ejecuciones de obra cuando su destinatario sea una comunidad de propietarios.Read the conditions again: an individual, not acting as a business, using the home privately. Where you live is not among them, and neither is where you pay tax. That is the answer, and it comes from the article rather than from anyone's reading of it.
The reduced rate is one thing; the reliefs are another. Several of them attach to a habitual home or to a tax a non resident does not file, and that condition is in the text itself rather than in a rule about foreigners.
The provision attaches the deduction to your habitual dwelling, or to another dwelling you own that you had let out as housing at the time or that was waiting to be let. A second home that is neither of those two is not named in the sentence.
[...] por las obras realizadas durante dicho período para la reducción de la demanda de calefacción y refrigeración de su vivienda habitual o de cualquier otra de su titularidad que tuviera arrendada para su uso como vivienda en ese momento o en expectativa de alquiler, siempre que en este último caso, la vivienda se alquile antes de 31 de diciembre de 2027.The provision subtracts it from the state part of the personal income tax bill. That is the tax Spanish residents file. A non resident owner files a different tax, and the pages that describe that tax are listed separately here.
El importe de estas deducciones se restará de la cuota íntegra estatal después de las deducciones previstas en los apartados 1, 2, 3, 4, y 5 del artículo 68 de esta ley.The decree requires the dwelling to be the habitual and permanent home of its owner, usufructuary or tenant at the moment the grant is applied for, and says this may be evidenced with a municipal registration certificate.
Las viviendas para las que se solicite financiación de este programa han de constituir el domicilio habitual y permanente de sus propietarios, usufructuarios o arrendatarios en el momento de solicitar la ayuda. Dicha circunstancia se podrá acreditar mediante certificación o volante de empadronamiento.The non resident income tax law taxes the gross amount as a general rule, and then opens a special regime for taxpayers resident in another member state of the European Union, extended to the European Economic Area where there is effective exchange of tax information. Those two are the named categories in the article.
Con carácter general, la base imponible correspondiente a los rendimientos que los contribuyentes por este impuesto obtengan sin mediación de establecimiento permanente estará constituida por su importe íntegro [...] 6. Cuando se trate de contribuyentes residentes en otro Estado miembro de la Unión Europea, se aplicarán las siguientes reglas especiales.The tax office publishes a page listing what changed for residents of the United Kingdom for income arising from 01 January 2021. Two of its bullets are the expense deduction and the rate. This is the tax office describing its own position, and it is the only source in this file that names the country.
No se podrán deducir los gastos previstos en el artículo 24.6 TRLIRNR [...] dejará de ser aplicable el tipo de gravamen general del 19%, propio de los residentes en otro Estado miembro de la UE, o del EEE con los que exista normativa sobre asistencia mutua en materia de intercambio de información, y pasará a ser aplicable el 24%. Entre estas rentas pueden citarse: rendimientos de inmuebles, rendimientos del trabajo, renta imputadas de bienes inmuebles.Naming the silences is part of the answer. On these points the published sources do not decide the case either way, so this page does not either.
This page sets out what the published sources say, with the article and the date next to each line, so you can check them yourself. It is not tax advice and it does not tell you what applies to your own situation. For that, ask the Agencia Tributaria or a gestor.
Every figure on this page carries its article, its Spanish sentence and the date the source itself bears, checked on 2026-08-17. 18 figures in total, each one linked back to the law or the tax authority page it came from.
Working out what the job costs before the tax: renovating a house in Spain.
The article says private use and the binding answer says the reduced rate holds even where the person does not habitually live there. Neither text says how little use is still use, and neither was written about a holiday home standing empty. That gap is real and I am not going to paper over it. Ask agenciaTributaria,gestor.
The tax office summary says letting or business use rules out the reduced rate even where it is only partial, but it does not say how that works across a year, per invoice, or per part of the building. The frequently asked questions page answers a fully let dwelling, not a mixed one. Ask agenciaTributaria,gestor.
The condition is in the article, the evidence is not. The binding answers say repeatedly that questions of fact are for the taxpayer to evidence and for the tax agency to assess, and they name no document. Ask agenciaTributaria,gestor.
Nothing I opened describes that route. The tax office pages describe the rule and the invoice wording. They do not describe a correction procedure for the customer. Ask agenciaTributaria,gestor.
There are two official sources and they do not sit on the same date. The binding consultation that names British owners is from 2017 and reasons from European Union membership. The tax office page listing the changes for residents of the United Kingdom carries a later date. Deciding what that means for a given person is a judgement, and this file does not make judgements. Ask eigenaar,agenciaTributaria,gestor.
Not researched in this round. The national decree is in this file because I read it. The regions run their own calls and I have not opened them, so this file says nothing about them. Ask eigenaar.
