Last year, the Catalan government collected a record €6.069 billion in its own and transferred taxes, an unprecedented amount representing a 9.9% increase. This figure includes both taxes collected by the Catalan Tax Agency (ATC) and those collected by the central government and subsequently transferred, such as the 2025 tax. The amount, which doubles the revenue obtained in 2015, was driven by wealth and property transfer taxes, which rose by 9.6% to €835 million and 17.6% to €3.263 billion, respectively. Another major transferred tax, inheritance and gift tax, increased by 0.8% to €1.162 billion. Furthermore, the fiscal year closed with a deficit of 0.51% of gross domestic product (GDP), as explained by the Minister of Economy, Alícia Romero. For the second consecutive year, a current account surplus was achieved, reaching €549 million, compared to €381 million in 2024, and 97.2% of the total planned expenditure was executed.

In the context of the negotiations for the collection of all taxes resulting from the agreement for the new financing of the PSC and ERC, the Catalan Treasury nearly broke a record for revenue from its own and transferred taxes last year. The Catalan Tax Agency (ATC), the body on which these changes hinge, collected a total of €5.286 billion from these items in 2024, the second-highest figure ever achieved, only slightly surpassed by 2006 (€5.362 billion), when the Generalitat had virtually no taxes of its own. Last year's figure represented a 12% increase over the previous year, thanks to the boost in taxes linked to real estate activity, according to data from the Catalan government.

Catalonia is one of the autonomous communities that most makes use of its capacity to create its own taxes on elements that the State does not tax. In 2025 these taxes continue to emerge and in the State as a whole there are already 66 in operation, while in 2024 it closed with 54 autonomous taxes of its own. In the Catalan case, beyond environmental taxation, where Catalonia not only leads the collection of income but also the implementation of different tax figures, there are other taxable events on which new taxes have been created that will continue in force this 2025: sugary drinks or non-productive assets, tourist apartments and empty homes and empty homes.
