The tax residence certificate: how to be taxed at 19 % instead of 24 %

Here is a scene I see every year. Two people own identical flats in the same building on the Costa Blanca, both live outside Spain, and both file their non-resident tax return. One pays 19 % and the other 24 %. The difference is often neither the flat nor the adviser: it is a single piece of paper that one of them submitted and the other did not. That paper is the certificado de residencia fiscal (tax residence certificate).

Let me explain exactly what it is, who issues it (hint: not the Spanish tax authority), when it lets you drop from 24 % to 19 %, what happens if there is a treaty between Spain and your country, and why it is NOT the same certificate the police asked you for when you bought your property or opened your account. No jargon, step by step.

What determines whether you pay 19 % or 24 %

The non-resident income tax (IRNR) has a general rate of 24 %, but it drops to 19 % for taxpayers resident in another European Union or European Economic Area State with which Spain has an effective exchange of tax information (art. 25 of the TRLIRNR). In plain terms: if you live within the EU/EEA, you are in principle entitled to the reduced rate; if you live outside, you face the general one.

The European Economic Area, for these purposes, is not a catch-all: it means Iceland, Norway and Liechtenstein (the last added since 11 July 2021). For the remaining countries outside the Union — what we call third countries — the rate is 24 % and, on top of that, you cannot deduct the expenses related to the property (art. 24.6 of the TRLIRNR), something EU/EEA residents can do, for instance on a rental.

• You reside in the European Union: 19 % rate and the option to deduct expenses, evidenced with the tax residence certificate.
• You reside in the European Economic Area with exchange of information (Iceland, Norway or Liechtenstein): same treatment, 19 % and deduction of expenses.
• You reside in a third country (outside the EU/EEA): 24 % and no deduction of expenses, except what a double taxation treaty may allow you.

What the tax residence certificate is and who issues it

Here is the detail that causes the most confusion, so let us take it slowly. The tax residence certificate is issued by the tax authority of YOUR country, the country where you live, not by the Spanish tax authority. It is your home tax office that certifies, in black and white, that as far as it is concerned you are a tax resident there. With that document, Spain agrees to apply the reduced rate or the benefits you are entitled to.

In other words: the AEAT (Spanish tax authority) also issues residence certificates, but to prove that someone resides IN Spain (the reverse case, when a Spanish resident needs to prove it abroad). If you are a non-resident and you want the 19 % here, the paper you need comes from outside, from your own tax administration. Request it in good time, because each country has its own procedure and deadlines.

If there is a double taxation treaty with your country

Spain has signed double taxation treaties (convenios para evitar la doble imposición, CDI) with a great many countries. When there is a treaty with yours, the certificate must be issued specifically 'for the purposes of the Convention': a generic one merely stating that you live there is not enough — it must certify that you are a resident in the sense that treaty defines. The Spanish tax authority itself distinguishes between the with-treaty certificate and the without-treaty certificate, and they are not interchangeable.

The concept of 'resident' for treaty purposes draws on Article 4 of the OECD Model Convention, which is the doctrinal reference almost every treaty follows. I mention it so you understand where the idea comes from, but note: the OECD Model is an international guide, not a Spanish law. What binds you is the specific treaty between Spain and your country. If there is no treaty, Spanish domestic law (the TRLIRNR) applies directly.

Do not confuse it with the police non-residence certificate

I see this confusion constantly, so it is worth clearing up. The NON-residence certificate issued by the National Police is something completely different: it is the one you were asked for (or will be asked for) to open a bank account or to buy the property, and it proves to the bank or notary that you do not legally reside in Spain. It has nothing to do with your tax rate.

The FISCAL residence certificate is the opposite and is issued by your country's tax office: it tells the Spanish tax authority 'I am a tax resident in such-and-such a place, apply the 19 % or the treaty to me'. One is from the police and looks towards the bank; the other is from your tax office and looks towards the Spanish treasury. Mixing them up is a classic that costs time and, sometimes, money.

If you own a property on the Costa Blanca and you are not sure which rate you are being taxed at, write to me. I review your tax residence, the treaty that applies to you and the documentation you need, and I make sure you apply the correct rate: not a euro too much, and no nasty surprises. Sometimes, that 5 % difference is precisely the paper that was missing.
