Summary
Half of Zurich's municipalities sent their taxpayers incorrect information about the 2026 tax return: they pointed to an offline download option that the canton had abolished. 77 municipalities are affected, distributed across the entire canton. The cantonal tax office ordered the affected municipalities to correct the error and announced an analysis of the incident. Additionally, the cantonal police abandoned a planned 30 km/h speed zone on Seestrasse in Horgen, and the City of Zurich mourns the death of musician Dominique Grandjean.

Clarus Lead
The Zurich cantonal tax office faces a coordination problem: while the canton abolished the offline function for the 2026 tax return, nearly 80 municipalities simultaneously sent out letters with outdated download instructions. This incident reveals structural deficiencies in communication between the cantonal level and municipalities—especially on a sensitive subject like tax payments. The tax office responded with mandatory corrections on municipal websites but also announced more in-depth analyses.
Clarus Original Work (Required)
Clarus Research: 77 out of approximately 160 Zurich municipalities = roughly 48%—exactly half. The incident is not confined to individual regions but is distributed "across the entire canton." This suggests a mailing or synchronization problem.
Assessment: Taxpayers face immediate uncertainty: they receive official letters, follow the instructions, and then encounter non-existent download links. This undermines trust in government communications—especially since tax filing is time-sensitive.
Consequence: The tax office plans "further measures" (according to Carina Denz). This could mean: internal process review, liability questions for delayed filings, or stricter guidelines for municipal letters in the future. For citizens: corrections must be actively discovered through website channels—not everyone will automatically receive them.
Detailed Summary
The Tax Return Filing Incident
In the first week of January 2026, Zurich municipalities sent out standardized letters to their taxpayers with access credentials for online tax returns. Approximately 77 of these municipalities also included notices that one could download the program and complete the return offline on one's own computer.
Exactly this offline function no longer exists as of 2026—the canton had eliminated it. This means: the municipal letters pointed to a technical function that was not available. Taxpayers who followed the instructions encountered 404 errors or empty download links.
Carina Denz from the cantonal tax office confirmed the incident but could not explain on request why the municipalities distributed the outdated information. This suggests that either the communication chain from the canton to the municipalities broke down or that municipalities did not keep their template texts current.
The tax office responded with an order: all 77 affected municipalities had to publish a correction on their websites and clarify that the download version no longer exists. In parallel, the tax office announced a comprehensive analysis—apparently to prevent similar incidents.
Additional Topics from the Regional News
Seestrasse Horgen: Speed Limit 30 Cancelled
The cantonal police had planned to reduce the maximum speed on a 500-meter stretch of Seestrasse in Horgen from 50 to 30 km/h—the reason was noise protection. The Horgen municipal council, as well as SVP and FDP parties, appealed. Instead of proceeding with the legal process, the cantonal police withdrew the measure of its own accord. Horgen would have been—alongside the City of Zurich—the first municipality on the left shore of the lake with a 30 km/h zone on Seestrasse.
Music World Mourns Dominique Grandjean
Zurich musician and later psychiatrist Dominique Grandjean has died at the age of 81. Grandjean wrote the song "Campari Soda" in 1977 with his band Taxi—originally a cult song in German-speaking Zurich that only became a hit decades later, partly thanks to a cover version by Stefan Eicher and later a Campari brand commercial. Grandjean himself said about his most successful piece: "For me, it is certainly a stroke of luck. It's as if it had flown to me from outside." Just under three years ago, the retired musician founded a new band in which his daughter also played.
Key Points
Coordination Problem: 77 Zurich municipalities (approximately 48%) sent out outdated tax information even though the canton had abolished the offline function.
Trust Issue: Official letters with incorrect technical instructions undermine trust in government communications—especially for time-sensitive tax filings.
Insufficient Response: The ordered website corrections do not automatically reach all taxpayers; the tax office plans "further measures" for analysis.

- Action: If uncertain, call the tax office directly or send a written inquiry.
- Monitor: Whether new announcements regarding offline discontinuation are issued.
For Municipalities:
- Action: Review correction texts and place them prominently (not just a small notice).
- Monitor: How many citizens perceive the correction.
For the Tax Office:
- Decision: Which "further measures" (pre-approval, template control check)?
