Registering and filing your tax return in Spain

In this article we will go through some relevant information regarding your tax return in Spain. However, we would like to remind you that taxes in Spain can be complicated and you could be subject to fines or penalties if you miss a deadline or don’t do your taxes properly. Advisably, you should seek fiscal advice from an expert to avoid possible complications.

How to file your tax return in Spain?

To file your resident tax return in Spain for the first time, you need to register with the Agencia Tributaria, or the Spanish Tax Authority.

To do this, you’ll need:

  • Your Foreigner’s Identity Number (NIE)
  • The form Modelo 30, which registers your obligations as a resident taxpayer. You’ll also need to fill out this form if your details have changed.

Tax return in Spain if it’s your first year as a Spanish tax resident

Remember, if it’s your first year as a Spanish tax resident, you have to file a declaration irrespective of your income. Spanish income tax declarations are made using the form Modelo 100. At the time of writing, the deadline for submission was 30th June 2020 for the preceding tax year. You can find advice about how to complete the form on the Spanish Tax Authority website. Alternatively – and advisably – you should seek advice from an expert about how to complete your tax return in Spain.

Tax return in Spain after the first yeart

After the first year, you won’t have to file a Spanish tax return if the following applies to you:

  • Your income from all sources is less than €12,000.
  • If you have a single pension worth less than €14,000.
  • You have less than €1,600 worth of interest or investment income.
  • Rental income of less than €1,000.
  • If you earn less than €22,000 as an employee, as your employer will deduct your income tax at source.

Note: Taxation if you’re self-employed

If you’re self-employed, or an autonomo as they’re called in Spain, you’ll pay your tax quarterly. However, you still need to make an annual tax declaration. Here, the Tax Authority will calculate whether you’ve paid too much or too little across the course of the year. Considering the requirement of quarterly returns plus an annual declaration, we would strongly suggest seeking the advice of an accountant or fiscal representative.

Hi there, I have started work in Spain under a contrato indefinido on the 8th of January 2019. Up until December 2018 I was working as a self employed in the UK. I was wondering if I have to declare any of my UK income in the Spanish tax declaration for 2019, because – even though I have only been working until December 2018 in the UK, the tax year runs until April 2019?

Hi Gudrun,
The Tax year here in Spain is January to December so you do not have to declare the income prior to this in the Spanish Tax declaration.
