Income Tax Return in Madrid
Does filing your tax return cause you doubts and stress? If you are a resident of Madrid, self-employed, employed or even if you have income from secondary activities, filing your tax return correctly is crucial to avoid penalties and take advantage of possible deductions. In this article, we explain in detail what you need to know about this procedure and how to do it. Eurolex Study can help you manage it easily and safely.
What is the income tax return and why is it important?
The income tax return is a mandatory procedure through which individuals inform the Treasury about the income obtained during the previous fiscal year. This process allows calculating whether you must pay additional taxes or, on the contrary, whether you are entitled to a refund.
Who is required to submit it?
Although not everyone is required to file a tax return, the following cases usually require filing a tax return:
- People with annual income of more than €22,000 from a single payer.
- People with incomes exceeding €14,000 when there is more than one payer and one of them contributes more than €1,500.
- Self-employed workers and professionals with economic activities.
- People with income from rentals or financial investments.
Key dates for the presentation
The deadline for filing income tax returns usually begins in April and ends at the end of June. It is essential to comply with these dates to avoid penalties.

Common challenges when filing your tax return
Errors in calculations
A small error when declaring income or deductions can lead to penalties or requests from the Treasury.
Lack of knowledge of deductions
Many people do not take advantage of the deductions to which they are entitled, such as for renting a primary residence, having a large family or having a disability.
Complexity in particular situations
Cases such as income from economic activities, investments abroad or changes in family situation can make the declaration more complicated.
