- Spain recorded the highest increase in tax pressure among EU member states over the last decade, with a rise of 2.9 percentage points of GDP.
- The surge is almost entirely attributed to higher taxes on labor, including income tax and social security contributions, while capital and consumption taxes stagnated or fell.
- Spain remains the only EU country with a net wealth tax and has one of the lowest implicit tax rates on consumption in the bloc.
- Despite the sharp rise, Spain's overall tax burden still lags behind the eurozone average, with projections showing a persistent gap through 2027.
The European Commission has confirmed that Spain experienced the largest jump in tax pressure across the European Union over the past ten years. According to the 2026 Annual Taxation Report, the country’s tax-to-GDP ratio climbed by 2.9 percentage points when comparing the 2015-2019 period with the 2020-2024 period. This increase puts Spain ahead of all other member states in terms of how much more it now collects relative to the size of its economy.
The report, released on Friday, compares the evolution of tax systems across the 27 EU nations. It highlights that the rise in Spain is almost exclusively due to higher revenues from labor taxes, while taxes on capital barely moved and those on consumption actually declined. This pattern has sparked debate about who is really footing the bill for the country’s growing public coffers.
The Biggest Jump in the EU
Spain’s 2.9-point increase is well ahead of the next closest countries. Lithuania saw a rise of 2.3 points, while Luxembourg came in at 2.2 points. Other nations with notable increases include Poland, Cyprus, Slovakia, and Latvia, all of which posted gains above one percentage point. On the flip side, Malta and Hungary recorded the biggest drops, each falling by 2.8 points, followed by Belgium, Ireland, Sweden, and France, all with declines of more than one point.
The EU average has remained fairly stable since 2015, meaning Spain’s surge is driven by domestic factors rather than a broader continental trend. The report notes that the overall tax-to-GDP ratio for the 27-member bloc has barely changed over the decade.
Why Labor is Bearing the Brunt
Bruselas is clear about the root cause: the increase in Spain’s tax pressure is almost entirely due to higher taxes on work. Income tax (IRPF) and social security contributions account for more than 2.5 of the 2.9 percentage points. The report points to two specific mechanisms. First, the widespread failure to index tax brackets to inflation—known as “fiscal drag” or “progresividad fría”—means that as nominal wages rise to keep up with prices, workers are pushed into higher tax brackets without any real gain in purchasing power. Second, successive increases in social security contributions, including the introduction of the Intergenerational Equity Mechanism (MEI) in 2023, have added to the burden on both employees and employers.
Meanwhile, taxes on capital have barely budged, and revenues from consumption taxes have actually fallen. This imbalance has raised questions about fairness, especially as the government looks for ways to meet fiscal targets without squeezing workers further.
A Unique Tax Landscape
The report also highlights a couple of features that make Spain stand out. For one, Spain is the only EU member state that still levies a net wealth tax. The Commission notes that its effectiveness depends heavily on how the tax is designed and whether the administration can enforce it properly. For another, Spain has one of the lowest implicit tax rates on consumption in the Union, at 13.6% in 2024, trailing only Malta (14.2%) and Germany (15%).
On the territorial side, Spain is one of just four EU countries—alongside Germany, Belgium, and Austria—where regional governments have their own tax-raising powers. In 2024, Spain’s autonomous communities collected 16.9% of total tax revenue. Interestingly, academic studies cited in the report suggest that greater regional autonomy in Spain does not lead to higher overall tax pressure for citizens, unlike in some other federal systems.
Still Below the Eurozone Average
Despite the rapid rise, Spain’s overall tax burden remains below the eurozone average. In 2024, tax revenues accounted for 36.8% of GDP, compared to 39.8% for the euro area. In 2025, the figure edged up to 37.8%, still 2.5 points below the eurozone’s 40.3%. The gap is expected to persist: Bruselas projects Spain’s tax pressure will reach 38.2% in 2026 and 38.4% in 2027, while the eurozone is forecast to stay at around 40.6% in both years.
The countries with the highest tax burdens remain Denmark (45.2%), France (43.5%), and Austria (43.4%), while Ireland (21.7%), Romania (27.9%), and Malta (28.8%) sit at the bottom. Spain’s position in the middle of the pack, but with the fastest upward trajectory, raises the question of how much further it will go before converging with its eurozone peers.
Outlook and Projections
Looking ahead, the Commission expects the gap to narrow only slowly. Spain’s projected increase of 1.6 points over three years (2025-2027) is faster than the eurozone’s 1.1 points, but the starting point is lower. The report arrives as Spain negotiates new fiscal rules with Brussels, and the government faces a dilemma: the only revenue source that has proven reliably expansionary is labor taxation, which also generates the most social resistance. Meanwhile, the coalition government is under pressure to transfer more tax powers to the regions, a move that could complicate the fiscal outlook.
All in all, the data paints a picture of a country that is raising taxes faster than any other in the EU, but still has room to go before it reaches the average of its currency union. The burden, however, is falling disproportionately on workers, while capital and consumption remain relatively lightly taxed. Whether this trend continues will depend on political decisions in Madrid and the ongoing dialogue with European institutions.
