Family
Parents in Catalonia can deduct €150 for each child born or adopted in 2025. If the tax return is filed individually, each parent receives this amount. If it is filed jointly, the deduction is double this amount per child.

Investments
You can also deduct 40 percent, up to a limit of €6,000, on amounts invested as an angel investor. When it comes to companies created or owned by universities or research centres, this increases to 50 percent, with a maximum of €12,000.
To benefit from this deduction, your shareholding (or that added to those of your family members) cannot be more than 35 percent. You also can’t apply for this deduction if you hold management position in the company or are an employee. It must also be a public limited company, cannot be listed on stock exchanges and must have been incorporated within the last three years.
It’s important to note that these specific deductions are only applicable to those living in Catalonia, if you live in a different region, they might not all be available to you. If you think you may be eligible for one of these deductions, you should contact your gestor or accountant to find out more. It’s worth also keeping in mind that they are not automatically applied, so you must apply for them on your tax return.
