How to file and pay modelo 210 from outside Spain

The three ways to identify yourself to the AEAT, and which one is yours

To file a self-assessment with the AEAT (the Agencia Estatal de Administración Tributaria, Spain's tax office) you have to prove who you are, and there are three ways of doing it. Only one of them is built for someone who lives outside Spain.

The third one is what breaks the deadlock. Article 14 of Order EHA/3316/2010, the order that governs modelo 210, lets you complete and file a predeclaración with no electronic identification of any kind. And it goes further: if you have no Spanish NIF, the form itself issues a Código Identificativo, an identifying code (article 14.1.º.b), which identifies that particular return. You do not have to get a NIE in order to comply.

One distinction worth keeping straight: whose return it is and who sends it in are two different things. For imputed income, rents and property sales the declarant has to be the taxpayer (article 2.2 of the same order), although a colaborador social (an authorised tax agent) or a registered representative can transmit it with their own certificate (articles 12.1.c, 13.1.c and 13.7). Either way the return stays yours.

The predeclaración, step by step

The route has three acts and ends in a document with a number on it.

• 1. You fill in the modelo 210 form on the sede electrónica (the AEAT's official website for tax procedures), without identifying yourself. About the taxpayer: name and surnames, country of tax residence (this is the fact that decides whether your rate is 19% or 24%, article 25.1.a of the IRNR Law), date and place of birth, address in your country, phone and email. About the property: referencia catastral (the cadastral reference, the unique code every Spanish property has for tax purposes), valor catastral (the cadastral value, an administrative value of the property that you read on your IBI receipt, the annual property tax bill your town hall sends) for the year you are declaring, full address, your ownership share, the legal title and the number of days in the year the property was yours.
• 2. You choose how to pay and you get the payment document. That document carries the payment identifier, which is the piece everything that follows turns on. If you are going to pay by transfer, you are also asked for the first eight positions of the IBAN of the account the transfer will be ordered from.
• 3. You pay. And here is the part almost nobody gets first time round: on this route there are not two separate acts, filing on one side and paying on the other. The filing date is the date the money is credited to the AEAT's restricted account. Paying is filing.

That country of residence line matters more than it looks, and it is where British readers get a nasty surprise. Article 25.1.a of the IRNR Law charges 19% to residents of an EU Member State and of an EEA State with effective exchange of tax information, which covers Iceland, Norway and Liechtenstein, and 24% to everyone else. The United Kingdom stopped being a Member State in 2021, so British owners, the largest group along the Spanish coast, moved from 19% to 24%. The same 24% applies if you live in the United States or in Switzerland. Irish, German, Dutch, Danish and Swedish owners stay at 19%.

One calendar detail that changes in a few months: if you file during 2026 you use the previous form, and from 1 January 2027 every self-assessment goes on the new form set out in Order HAC/623/2026, whichever year you are declaring. The new form adds the boxes "N.º de días" (number of days) and "Cuota participación" (ownership share) and a box [61] for the cadastral reference key, with a value of 1 if the property has a referencia catastral and 2 if it does not.

And the whole route repeats as many times as you have returns: it is one 210 per property, per co-owner and per tax year, so three properties mean three forms and three different identifiers. The reason behind that rule is in the general guide to modelo 210.

Paying by transfer from abroad: the four traps

Read this twice. The four rules below are not procedural tips: each one has a tax consequence, and three of them can put you out of time without anyone telling you.

• The payment identifier expires after 30 calendar days. Consequence: after that, the transfer no longer matches any return. Generated on 20 November, it dies on 20 December and you have to go back to the form for a new one.
• The transfer reference must carry that identifier and nothing else. Not your name, not "modelo 210", not the referencia catastral. Consequence: a contaminated reference makes the payment impossible to match, and with no matched payment there is no return filed.
• It is rejected if the transfer leaves a bank that collaborates with the AEAT, which in practice means a Spanish bank. Consequence: if you order the payment from your account in Spain, the money comes back. This route exists for money arriving from outside.
• The filing date is set by the credit to the restricted account, not by the instruction you give. Consequence: the days your bank takes count against your deadline. Ordering on 30 December can leave you out of time.

The whole example, from the tax to the surcharge. A flat on the coast, valor catastral €92,000, in a town whose values were revised inside the window in article 85.1 of the IRPF Law, so the imputation is 1.1%. Taxable base: 92,000 × 1.1% = €1,012. A single owner resident in France, so the rate is 19% (article 25.1.a of the IRNR Law). Tax: 1,012 × 19% = €192.28, imputed income for 2025, due on 31 December 2026. He orders the transfer from his French bank on 30 December and the money is credited on 2 January 2027: the return is late. Surcharge under article 27.2 of the General Tax Law, 1% because a full month of delay has not gone by, that is €1.92, which comes down to €1.44 with the 25% reduction in article 27.5. Not much money, a lot of avoidable trouble: order the transfer with days to spare, not hours.

If that same owner lived in the United Kingdom or in the United States, everything in the example would work the same way except the rate, which would be 24%, and the tax, €242.88.

SEPA direct debit: who can use it and the three dates

The other way to pay is domiciliación (direct debit), and since 1 February 2024 it stopped being a privilege of people with a Spanish account. Order HFP/387/2023 accepts a direct debit on an account held at a non-collaborating institution in the SEPA area, which is 36 countries and includes the United Kingdom and Switzerland. Your account in London or in Zurich will do.

It comes with a requirement that puts it out of reach for a lot of people: it needs online filing, and it needs it within the first part of the window. Filing online means identifying yourself, so direct debit is the natural route for someone who has a certificado digital or Cl@ve, or for someone who lets a colaborador social or a registered representative transmit the return with their own certificate. If your identification is the predeclaración in article 14, your road is the transfer.

And here is the confusion that produces more late filings than any other: there are three different dates and they do not coincide.

What you do not need: a representative, a residence certificate or a Spanish account

Three things that are treated as compulsory in forums and in conversations with neighbours, and are not.

• A fiscal representative in Spain. Article 10.1 of the IRNR Law only requires you to appoint a representante fiscal (fiscal representative) when you operate through a permanent establishment, in the cases in its articles 24.2 and 38, when you are resident in a territory with no effective exchange of tax information, or when the tax authorities require it. For an empty flat you do not need one. That said, that last limb expressly mentions "the ownership of immovable property in Spanish territory" as a reason for which the AEAT may demand one: if they do, it stops being optional, the appointment has to be notified within two months, and failing to do so is a serious infringement of €2,000, rising to €6,000 if you are resident in a territory with no effective exchange of tax information (article 10.4).
• A certificate of tax residence. Article 7.1 of Order EHA/3316/2010 requires one in order to apply an exemption, a limit under a double tax treaty or the deductible expenses in article 24.6 of the IRNR Law. In a plain imputed income none of those three comes into play: there is no exemption to invoke, there are no expenses to subtract (article 24.6 speaks of rendimientos, actual yields, and imputed income is not one) and treaties drafted along the lines of the OECD model allow income from immovable property, including the owner's direct use of it, to be taxed with no rate limit in the country where the property is. Check your own country's treaty, but as a rule you will not need the certificado de residencia fiscal.
• A Spanish bank account. Neither to pay nor to set up a direct debit. With the transfer it is exactly the other way round: if it leaves a Spanish bank, it is rejected. And for the direct debit, since 1 February 2024 your account in any SEPA country works.

What is compulsory, with no exception, is filing: article 28.1 of the IRNR Law requires every taxpayer without a permanent establishment to declare and pay, and the only dispensation there is, in article 28.3, requires tax to have been withheld, which is impossible when there is no payer.

If you get something wrong or you miss the deadline

Two different scenarios with different solutions, and in both of them the variable that decides the price is the same: who moves first.

You got something wrong on a return already filed. It is put right with a declaración complementaria (a supplementary return) or with a corrective self-assessment, depending on the form and the period, because Royal Decree 117/2024 has been replacing, form by form, the old pairing of supplementary return plus request for rectification with a single figure. What does not change is the direction of the error: if you paid too little there is money outstanding and article 27 of the General Tax Law comes into play; if you paid too much there is no amount to pay on which any surcharge could be worked out. With the 210 there is a further detail of its own: since it is a return per property, per co-owner and per tax year, only the affected return is corrected, and article 27.4 requires every late self-assessment to expressly identify its period and to contain only its own data.

You missed the deadline. If you file on your own initiative, before anything arrives from the AEAT, what applies is the recargo por declaración extemporánea (the surcharge for filing late) in article 27.2: a fixed 1% plus another 1% for each full month of delay, worked out on the amount to be paid. Past 12 months the surcharge becomes 15% and late payment interest is added from the day after the end of that twelfth month. And article 27.5 reduces the surcharge by 25% if you pay all the rest on time.

If the requerimiento (the formal demand from the tax office) arrives before your return does, article 27 no longer covers you: it is kept for people who put things right on their own initiative. What opens instead is the route of the sanción tributaria (the tax penalty). Between a predictable surcharge and a penalty procedure there are usually only a few weeks, and you are the one who decides them. You can estimate the cost of each year outstanding with the late filing surcharge calculator.

The alternative: having the calculation and the form done for you

With what is in this guide you can do the whole thing yourself, and for one property with a single owner it is an afternoon's work: you look up the valor catastral on the IBI receipt, you apply 1.1% or 2%, you pro rate by days if the property was not yours all year, you apply 19% or 24%, you fill in the predeclaración under article 14 and you order the transfer with time to spare.

The two points where people get stuck are always the same. The first is the imputation percentage: it depends on the year your municipality last carried out its general collective valuation, and the Catastro website does not publish that, so it has to be tracked down. The second is the counting, which almost nobody gets right: one return per property, per co-owner and per tax year, so a married couple with a home, a garage and a storage room with separate cadastral references file six returns a year, not one.

If you would rather have the calculation and the form handed to you ready, with the count and the total in front of you before you pay anything, that is exactly what kontora does. The details are on the modelo 210 service page and on pricing.
