Tax litigation in Spain has reached levels that far exceed those observed in other European countries. This excessive number of disputes between taxpayers and the tax authorities creates legal uncertainty, slows down investment, and hinders economic development.
At Resitax, a tax law firm in Mallorca, we work every day to protect our clients’ rights against a tax system in urgent need of reform.
A growing phenomenon: tax litigation in Spain
This is not just a perception: official data confirms it. More than 60% of contested tax assessments are overturned or modified by the courts. This high rate of correction reflects deep structural issues in the tax administration’s procedures.
Economic impact of tax litigation
- Over €40 billion in outstanding tax debt managed by the AEAT.
- More than €12 billion in compensation paid following rulings against the Treasury.
- Automatic penalties imposed without proof of guilt — a practice being challenged by the Supreme Court.
Structural causes of tax litigation in Spain
At Resitax, we have identified several causes that explain the high rate of tax litigation in Spain:
1. Unstable and complex legal framework
Spanish tax law is highly technical and constantly changing, generating confusion even among professionals.
2. Lack of a collaborative culture
The relationship between tax authorities and taxpayers is often adversarial, discouraging resolution and increasing litigation.
3. Long and costly procedures
Administrative and court proceedings can take years, adding legal uncertainty and high costs for individuals and businesses.
4. Lack of specialized tax courts
Without dedicated tax courts, rulings may be inconsistent and proceedings significantly delayed.
IEE proposals to reduce tax litigation
The Institute for Economic Studies (IEE) has proposed several solutions — many of which we at Resitax support:
Clear and stable regulations
Tax laws must be simplified and written in accessible language to avoid confusion and misinterpretation.
Promotion of dialogue
Trust-based communication between taxpayers and authorities can reduce the number of disputes.
Alternative resolution methods
Mediation, conciliation, and arbitration can alleviate pressure on the courts and offer faster solutions.
Procedural reform and judicial specialization
Creating tax-specific courts and reducing legal timeframes would improve case management and fairness.
Administrative accountability
Officials must face consequences when they act clearly against the law, ensuring legal certainty for taxpayers.
