Report puts the tax wedge on the average Spanish salary at 54%

The state now takes more than half of what a salary costs

How much of what your employer pays for you actually reaches your pocket? A report shared in the debate puts what the tax agency (Hacienda) and Social Security take from the average worker at 21,100 euros a year, approaching 54% of the total salary cost. The figure was put on the table by an analysis circulating these days and has peine an old unfinished business: how much of our effort goes to the state and how much comes back in services. The answer, depending on how you look at it, ranges from plunder to simple arithmetic.

What that 54% includes and why the figure stings

The calculation adds up social security contributions —both the worker's and the employer's, which also come out of the same pot— plus income tax (IRPF). It is not a new rate or a hidden tax: it is the tax wedge, the gap between what an employee costs and what they receive. The problem is not that it exists, but its size and its trend. With 141 tax increases accumulated during Sánchez's time in office, according to the tally going around, the feeling that the state squeezes harder every year has a numerical basis that is hard to dispute.

The fine print matters. On high salaries the wedge rises less than it seems, because contributions are capped: above the maximum base (around 4,900 euros gross per month in 2025) the salary stops paying contributions and only income tax remains, with marginal rates of 45-54% depending on the region. Since 2025 there is also a solidarity levy on what exceeds that cap, still small. The full calculation, broken down item by item, yields a surprising difference.

The inflation that raises income tax without touching the rates

Here is the mechanism that raises the most hackles. Failing to adjust income tax brackets for inflation amounts to raising it on everyone, every year, and the higher inflation is, the bigger the disguised increase. With each salary or pension update, whether at CPI level or below, the effective rate rises: the increase is taxed at the marginal rate and the tax agency keeps at least a third. Eight years of losing purchasing power, even for pensioners and civil servants, through this silent channel.

The official counterargument is that rates have not been touched in quite a while and that Social Security has not risen beyond the MEI, that 1% of the salary (an extra levy for the pension system). True on paper. False on the payslip: the contribution cap has gone up, and revenue is hitting records while the deficit does not fall. Never has so much been collected with such a big hole. Someone should explain that.

The salary that doesn't rise and the housing that does

The other half of the problem is not the tax, it's the payslip. Salaries have been practically frozen for more than fifteen years, except for the minimum wage, and average wages are converging downward. Productivity sets the ceiling, but the floor is set by bargaining power: abundant labour, an economy centred on low value-added sectors and a self-reinforcing cycle. Meanwhile, GDP is rising because there are more of us (49.5 million), not because we are more productive, and debt falls as a percentage only because the denominator grows.

Who pays for the party

The tax agency's numbers paint a curious country: out of 49.5 million inhabitants, only 24 million file a tax return, and of those, 10.7 million —those earning between 21,000 and 150,000 euros— provide 75% of income tax revenue. The base holding up the whole structure is narrower than it seems. And on that base rest pensions, public administrations, municipal contracts and everything else.

The discussion drifted, as always, towards spending: some point to the structure of the state and its plums; others argue the problem is that not everyone contributes equally and that the system loads onto nine backs what should be spread across ten. The conclusion nobody will sign: while the wedge grows and wages don't, the oar stays in the water.
