New Tax Rises Coming to Spain in 2026 « Euro Weekly News

Spain’s government continues to insist that taxes are not going up. Yet for many workers, freelancers, homeowners and small business owners, the reality in 2026 feels very different.

A growing number of measures already approved or quietly embedded in existing rules are set to push the overall tax burden higher next year – even without any headline-grabbing tax hike announcement. According to the Impuestómetro 2025 report from the Juan de Mariana Institute, Spaniards have faced 94 tax and social contribution increases since 2018, delivered through a mix of direct changes and more subtle adjustments.

While much of Europe reduced its tax pressure after the pandemic, Spain moved in the opposite direction. Across the EU-27, the average tax burden fell by almost one percentage point of GDP. Spain’s rose by nearly two points, making it one of the countries where fiscal pressure has grown the fastest in recent years.

And 2026 looks set to continue that trend.

Higher social contributions: a quiet rise in the cost of work

One of the biggest impacts will come through social security contributions, which are increasing on several fronts at the same time.

The Intergenerational Equity Mechanism (MEI) will rise from 0.8 per cent to 0.9 per cent. For the self-employed, this increase is fully absorbed personally. For employees, the cost is shared between worker and employer, but either way it raises the overall cost of employment.

At the same time, the maximum contribution base climbs from €4,909 to €5,101 per month, meaning higher earners and their employers will pay more into the system every month. This reduces net income while increasing labour costs for companies – something business groups warn could weigh on hiring and wage growth.

There is also a tougher solidarity surcharge for salaries exceeding the maximum base, applying rates between 1.15 per cent and 1.46 per cent on the excess income. Together, these measures quietly raise the cost of qualified labour without the political noise of a formal tax hike.

Income tax creep, rising council charges and a costly property update

Income tax is also set to rise – not through new rates, but through what economists often call “fiscal drag.” The government once again plans not to adjust income tax brackets for inflation. As wages slowly rise to keep pace with living costs, more income is pushed into higher brackets, even when real purchasing power barely improves.

Spain’s state income tax bands range from 9.5 per cent to 24.5 per cent, before regional surcharges are added. Without indexation, millions of workers effectively pay more tax each year without any visible reform being passed in parliament.

Local taxes are moving higher as well. From 2026 – municipalities must introduce a waste collection charge that fully covers the cost of the service. Until now, part of this expense was funded through general local budgets. Going forward, residents will pay it directly. Average municipal taxes already stand around €705 per person, and in cities such as Madrid the new charge could add roughly €140 extra per household.

Another major shift comes from the planned cadastre update in 2026, which raises the official reference values used for property taxation. While described as a technical adjustment, it affects several taxes at once: the property transfer tax on second-hand homes, inheritance and gift tax, and stamp duty. A higher reference value means higher tax bills across all these transactions – effectively delivering multiple hidden tax increases without new legislation.

Savings, agriculture and the hidden cost of public debt

Tax on savings is also changing at the top end. The highest rate on investment income – covering capital gains, dividends and interest – will rise from 28 to 30 per cent for amounts above €300,000. Lower bands remain unchanged, meaning the increase targets only the largest portfolios.

Meanwhile, the agricultural sector faces the removal of two long-standing deductions. Farmers will lose the 35 per cent deduction on agricultural diesel and the 15 per cent deduction on fertilisers from 2026, increasing operating costs in a sector already sensitive to energy prices and regulation.

Beyond formal taxation, economists also point to what they describe as a “hidden tax”: public debt. Spain is projected to close the previous year with public debt equivalent to roughly three full years of tax revenue. The Juan de Mariana Institute estimates that covering the structural deficit alone would imply an additional burden of about €929 per citizen over time – a cost that ultimately feeds into future taxes or reduced public services.

For households, the combined effect is not always immediately visible on a payslip or tax notice. But taken together – higher social charges, income tax creep, new municipal fees, property revaluations and selective tax increases – 2026 looks likely to tighten household budgets further.

Whether the government continues to describe this as ‘no tax rises’ may depend on definition. For many taxpayers, what matters is simpler: how much money is left in their pocket at the end of the month. And on that front, the direction appears clear.
