As most foreigners in Spain are well aware of, Spanish bureaucracy in Spain can be pretty complicated and confusing.

When it comes to carrying out official processes online, your NIE (Foreigner Identity Number) can help you to access certain government websites, often with the help of other means of identification such as your [email protected] PIN and your Digital Certificate

But one of the extra numbers that foreigners get asked for to gain access or carry out actions on these official sites is the Support Number or Número de Soporte

What is my Support Number used for?

Your Support Number is a type of ID number that you’ll need to type into the Spanish Tax Agency or other government websites in order to carry out a procedure online.

They will need this number in order to validate your identity, and more often than not foreigners will get the message on screen “Introduzca soporte válido” (write correct support number) when they get this number wrong.

In most cases, it’s Spain’s tax agency – la Agencia Tributaria–  which requires this support number for processes such as presenting your tax documents, paying fees and fines and requesting appointments.

You may also need to log on in order to see messages that the Tax Agency has left for you.  

As of April 7th, you have also been able to present your income tax corresponding to 2020.

Where can I find my Support Number?  

Your Support Number can be found on your identity document, such as TIE or green residency certificate, but the location of it will depend on which type of document you have.  

How to find your support number on your TIE or residence permit 

If you are from outside of the EU you will receive a TIE or residence permit in order to be formally registered in Spain. This is your foreigners’ Spanish ID card. It contains your personal data, photo and type of authorisation to live in Spain.

Usually, the number you will need on your card is your NIE, which begins with X or Y. 

Your support number however is different. This is the number found in the top right-hand corner. It consists of 8 digits and starts with the letter ‘E’.

Green residency certificate

For those of you that have the credit card-sized green residency document for EU citizens, you will find your support number on the back of the document in the bottom right-hand corner.

When you introduce your support number online from your residency card, it will need to be preceded by the letter ‘C’. If your number has less than 8 digits, you will also need to put a ‘0’ in front of the number. For example, if the support number on your card is 8254321, then you will enter C08254321.

For those with the older A4-sized green residency sheets, the support number is in the top right corner.

If you have the older A4 residency document featuring your NIE, then your support number will be found in the top right-hand corner and be filled out the same way with a ‘C’ in front.

Some foreigners in Spain have reported that they’ve had problems using their support number after being issued a new residency document.

This could be because, unlike the NIE number which remains the same forever, the support number does change. 

According to Hacienda’s tech support team AEAT, the best thing to do in such case is to fill in a form to explain the problem that is occurring.

Anyone residing in Spain for more than 183 days and earning over €22,000 a year, who is self-employed (autónomo), or moved here in the last year, must complete it. 

Your Spanish income tax return has to be filed by June 30th for the preceding year, in this case for 2021.

Spanish pension contributions

Up to €2,000 can be deducted for contributions to pension plans or up to 30 percent of the tax base (total income).

Property tax

Those who own a property in Spain will pay the yearly Impuesto Sobre Bienes Inmuebles, better known as IBI. This is similar to council tax in the UK and one of the expenses you can claim back on your annual declaration.

The costs of renovating your main home

Keep in mind, that you can’t just deduct the cost of any renovations on your home, particularly if they’re just cosmetic, but you can deduct for any renovations which reduce the demand for heating and cooling by at least seven percent. In this case, you can apply a 20 percent deduction, with a maximum of €5,000. 

Buying or rental costs of your main home

This expense can only be deducted by those who bought their property and signed the mortgage before January 1st, 2013 and must have included it in previous declarations. In the case of those who are renting, the signing of the contract must have been made before January 1st, 2015.

The tax benefit is up to 15 percent with a maximum limit of €9,040, while the maximum deduction will be €1,356.  

Some regions will also allow you to deduct further expenses if you buy a house in a rural area or habitually live in an area at risk of depopulation, such as in Andalusia, Cantabria, Castilla La-Mancha, Extremadura, Galicia, La Rioja and Valencia.  You can also deduct expenses for the cost of buying a residence for a particular group of people, be it young people in need, victims of domestic violence, disabled people or large families.


Donations of many kinds can be deducted on your annual tax declaration, whether they’re charitable donations, donations to cultural institutions, donations for scientific advancement, innovative technologies or the environment.

Generally, you can deduct 80 percent of the first €150 and 35 percent of any donations after that. If you have any doubts as to whether the donations you made last year can be included, it’s best to check with your accountant or gestor.

For educational studies and textbooks

Many times, you can deduct the cost of education and the textbooks associated with them. In general, you can deduct 15 percent of school fees; 10 percent of language courses and; five percent of the cost of purchasing clothing for exclusively school use.

However, this does not include claiming back for all courses, unless you are autónomo (self-employed) and they are designed to help improve your business. If you’ve taken a course, it’s best to check with your gestor or accountant to see if the fees can be included on your declaration as there are slight variations between regions too.

Investments in environmental installations (some regions only)

Many regions in Spain allow you to deduct costs of investing in environmental installations such as solar panels, thermal installations, and water-saving devices. This category also includes improvements made to your habitual residence due to disability or adaptation because of technical or structural issues. Some of the main regions you can deduct these expenses include Valencia, Balearic Islands, Canary Islands, Murcia and Galicia. Unfortunately, these are not included for Madrid or Catalonia.

Domestic help (some regions only)

In some regions in Spain, you can even deduct expenses for domestic help, such as cleaners, nannies or au-pairs. This is true in Madrid, Andalusia, La Rioja and Castilla y León.

Electric cars (some regions only)

Those who make an investment in buying an electric car may also be able to deduct the cost of this, depending on where they live. This is true if you live in Valencia, La Rioja and Castilla y León.

Standout regional differences

  • The Canary Islands and Cantabria are the only two regions that allow you to deduct private health insurance and other health-related expenses, but make sure you contact your gestor to find out exactly which health costs can be claimed for.
  • Andalusia is the only region where you can deduct legal expenses.
  • Public transport costs can be deducted in Aragón and Asturias.
