Vaud Tax Affair: 202 Million Francs, Two Criminal Proceedings and Unresolved Responsibility

Blog (EN)

Summary

by Ernst Anker with Claude Opus

The Canton of Vaud did not apply the tax shield "bouclier fiscal" in accordance with the law between 2009 and 2021. What sounds dryly like administrative technicality reads, upon closer inspection, like a textbook example of how an error becomes practice, practice becomes routine, and routine becomes political embarrassment.

At the beginning of June 2026, the cantonal tax administration quantified the lost revenue for the first time at 202 million francs. This corresponds to an average of 15.5 million francs per year. Of 2,793 benefiting taxpayers, 1,847 had no entitlement to the relief. According to the investigation report, the tax administration has been aware of the erroneous practice since 2011. Surprisingly little has happened nonetheless. Or, to put it more in Vaud terms: The tax shield apparently functioned excellently – just not for the state treasury.

Attorney General Eric Kaltenrieder opened a criminal proceeding against unknown persons on January 8, 2026. The basis is the investigation report by expert François Paychère from August 2025.

With the quantification of losses, the Vaud tax affair shifts from the question "how much?" to the considerably more uncomfortable question "who knew what – and why did nothing happen anyway?". The answer to this is politically sensitive. Because an error that lasts twelve years is at some point no longer a slip-up, but a business model with an official stamp.

The legal double track is explosive: In addition to the proceeding regarding the bouclier fiscal, a separate proceeding for abuse of office against Valérie Dittli has been running since September 2025. This puts precisely the politician who exposed the practice in criminal proceedings. She lost her department. The finance director of the period in question, however, now sits in the Council of States. One doesn't have to call this irony. But it helps.

Additionally piquant: The Canton of Vaud received funds from the national fiscal equalization as a recipient canton, while wealthy taxpayers were given excessive relief for years. To the rest of Switzerland, this sounds roughly like: One asks for solidarity while accidentally calculating the champagne tax at home in wellness mode.

Detailed Summary

The tax shield introduced in 2009 was supposed to limit the total tax burden on wealthy individuals. This is politically legitimate, provided it is done in accordance with the law. This is exactly where it falls short. According to François Paychère's report, a specially programmed computer system calculated the reliefs incorrectly from the beginning. The cantonal financial control confirmed the deviation: Only 946 of the 2,793 beneficiaries were entitled to the tax discount at all. Some of them also received excessive reliefs.

Particularly serious: According to the report, the erroneous practice has been known since 2011. However, the hints did not reach the State Council. Even a judicial objection in 2018 did not change anything fundamental. Only in 2021 did the Grand Council bring the regulation into legal conformity. Twelve years is an eternity in information technology, apparently a test phase in tax administration.

The criminal investigation now proceeds on two separate tracks. The proceeding opened in September 2025 concerns Valérie Dittli personally. She is accused of having instructed the tax director to revoke legally binding assessments of wealthy taxpayers. The proceeding opened on January 8, 2026 against unknown persons, however, concerns the unlawful application of the bouclier fiscal itself. It is intended to clarify how this practice could arise, why it was continued and why internal or external hints remained without consequence.

That Attorney General Eric Kaltenrieder demanded complete access to files is more than a formality. It shows that the judiciary is not simply examining a charming administrative anecdote from Lavaux, but a possible chain of omissions, gaps in responsibility and political protection.

Politically, the dispute over interpretive authority dominates. Government President Christelle Luisier Brodard speaks of the 202 million francs as a theoretical, not real loss. Her argument: It is unclear whether the affected taxpayers would have remained in the canton with correct taxation. This is not formally unreasonable, but politically convenient. Because with the word "theoretical", much can be softened: shortfalls, responsibility and occasionally memory gaps.

The government rules out reclaim. So far, it wants to hold no one responsible. Not even Pascal Broulis, who was finance director from 2009 to 2019 and whose maxim was that he applied "the law, nothing but the law, the whole law". The sentence now sounds like a political boomerang. Because if the whole law was really applied, the question arises which law the software read.

Several parliamentarians are now calling for a parliamentary investigation commission. This is understandable. Because the affair touches not only a technical miscalculation. It touches the core of state credibility: When normal taxpayers make mistakes, the tax authority usually reacts precisely, quickly and humorlessly. When the administration taxes the wealthy too low for twelve years, it suddenly says: complex matter, theoretical damage, no reclaim.

Key Statements

  • 202 million francs were lost to the Canton of Vaud between 2009 and 2021 according to the cantonal tax administration; reclaim is ruled out.
  • 1,847 of 2,793 beneficiaries had no entitlement to the relief according to financial control.
  • The erroneous practice has been known since 2011 according to the investigation report.
  • A judicial objection in 2018 did not lead to immediate correction.
  • Two separate criminal proceedings are running: one against Dittli for abuse of office, one against unknown persons regarding the application of the bouclier fiscal.
  • The whistleblower lost her department; the finance director of the years in question now sits in the Council of States.
  • The case also raises questions about the national fiscal equalization because Vaud simultaneously received funds from this system.

Critical Assessment

The Vaud tax affair is more than a cantonal calculation error. It is a stress test for political responsibility. The administration apparently knew the problem early. Politics reacted late. The judiciary is now investigating. And the government explains that the damage is theoretical.

This may be legally cautious. Politically, it sounds like the attempt to describe a burning roof as "heat development in the upper building section".

The case shows a familiar pattern: As soon as responsibility could become concrete, it is institutionally diluted. The software was programmed incorrectly. The administration did not forward hints. The State Council allegedly knew nothing. The beneficiaries cannot help it. Reclaim is not possible. And in the end, a shortfall remains that can indeed be quantified, but apparently belongs to no one.

This is exactly where the core of the affair lies. Not the 202 million francs alone are the scandal. The scandal is the question of whether a canton can tolerate an unlawful practice for years without someone ultimately bearing political or administrative responsibility.

Critical Questions

  1. Knowledge status: What internal documents prove that the erroneous practice has been known since 2011?
  2. Information flow: Why did the hints not reach the State Council – or if they did: who knew what when?
  3. Software governance: Who commissioned, reviewed and validated the calculation system for the bouclier fiscal?
  4. Control failure: Why did even the judicial objection of 2018 not lead to immediate correction?
  5. Political responsibility: What responsibility does Pascal Broulis bear as the then finance director for the administrative practice of his department?
  6. Scapegoat question: Why is whistleblower Dittli more in political and criminal focus than those who were responsible during the years in question?
  7. Damage concept: How robust is the distinction between "theoretical" and "real" damage when the canton itself quantifies the lost revenue at 202 million francs?
  8. Equal treatment: How does the canton explain to normal taxpayers that their errors are consistently corrected while reclaims are waived for the very wealthy?
  9. Fiscal equalization: How does the under-taxation of the wealthy reconcile with the simultaneous receipt of funds from the national fiscal equalization?
  10. Future: What control mechanisms will prevent in the future that a faulty tax program works for twelve years like a discreet butler for the wealthy?

Conclusion

The Vaud tax affair is a textbook example of power, administration and selective sharpness of the state. Towards normal citizens, the tax authority usually appears with ruler, reminder and default interest. Towards years-long miscalculations in favor of the wealthy, politics suddenly discovers the beauty of theoretical consideration.

The problem is not only that 202 million francs are at stake. The problem is that everyone could have been responsible, but no one wants to be accountable.

Or shorter: The bouclier fiscal did not only protect wealth. It apparently also protected careers.
