Summary
Swiss voters have decided to abolish the imputed rental value with just under 58% yes votes. The Federal Council aims for implementation starting in 2028, but the mountain cantons – including Graubünden – are demanding a postponement until 2030. Reason: The cantons and municipalities must develop replacement taxes to compensate for approximately 90 million francs in lost annual revenue. Graubünden's Finance Director Martin Bühler emphasizes that this process cannot be rushed.

The voting result is clear: 57.6% of Swiss voted for the abolition of the imputed rental value. Yet between popular mandate and implementation, massive questions loom. While the federal government targets 2028, the mountain cantons are blocking and demanding two additional years. This is not an ideological dispute – it is a question of feasibility: How do cantons and municipalities replace 90 million francs annually without creating new tax resistance?
Clarus Original Research
Clarus Research: Graubünden is particularly hard hit – with many municipalities and decentralized structure, more administrative units must redesign a property tax than in urban cantons. A 90 million francs tax shortfall is of existential importance for a mountain canton.
Classification: This is a classic conflict between democratic mandate (popular vote) and federal reality (cantons must implement). Mountain cantons with dispersed settlement patterns bear disproportionate administrative burdens.
Consequence for Decision-Makers: The Federal Council must decide by summer 2026. Overly short deadlines force poorly conceived replacement taxes and spending cuts; overly long timelines delay relief for homeowners.
Detailed Summary
Switzerland has decided via referendum to abolish the imputed rental value – a tax provision that has burdened homeowners for decades by taxing them on fictitious rental income they never received. The signal was clear, but the timeline remains contested.
The Federal Council signaled quickly: No earlier than January 1, 2028. However, the Conference of Mountain Cantons, in which Graubünden is also represented, submitted a letter to the federal finance department and demanded: January 1, 2030 – two years later.
The reason is obvious: Cantons and municipalities collectively lose approximately 90 million francs in annual tax revenue. They cannot ignore this gap or simply plug it with spending cuts. They must build a new property tax – a genuine wealth tax on real estate that must be legally watertight and should be harmonized across all municipalities.
Graubünden's Finance Director Martin Bühler made clear: This is not a delaying tactic. His government had already decided in the previous year to implement the property tax at cantonal and municipal levels. But "The whole process takes time." Why? Because Graubünden "has many municipalities" and each individual one must implement the new tax – administratively, legislatively, technically.
The property tax must "hold up legally," said Bühler. That means: It must withstand court scrutiny. A poorly constructed tax law could end up in mass litigation years later and call the whole thing into question again. So the mountain cantons don't want to slow things down – they want to do it right.
Next step: The Conference of Cantonal Finance Directors will weigh in on implementation. This statement will then flow into a "concrete proposal" to the Federal Council. This is to be approved before the summer break in 2026.
Key Statements
- The popular vote to abolish the imputed rental value clearly passed with 57.6%.
- The Federal Council plans implementation starting in 2028; the mountain cantons demand 2030.
- Those two years are intended to help cantons and municipalities design a legally secure property tax.
- Graubünden loses 90 million francs annually and must compensate for this across all municipalities.
- The Federal Council will decide on the binding timeline before the summer break in 2026.
Stakeholders & Affected Parties
| Group | Status |
|---|---|
| Homeowners | Benefit from abolition (no more taxation on fictitious rental income) |
| Cantons & Municipalities | Lose tax revenue, must develop property tax |
| Mountain Cantons | Particularly affected due to many decentralized municipalities |
| Federal Council / Finance Department | Must set deadline and ensure federal coherence |
| Tenants | Indirectly affected if property tax is passed on to rents |
Opportunities & Risks
| Opportunities | Risks |
|---|---|
| Abolition of imputed rental value sustainably relieves homeowners | Too short deadline leads to poorly conceived property tax |
| New property tax can be designed transparently and fairly | Mountain cantons cut services if transition period is too short |
| Two additional years enable cross-cantonal harmonization | Legal vulnerability of hastily constructed tax |
| Clear deadline (2030) creates planning certainty for cantons | Rental market could be destabilized by transition uncertainty |
Action Relevance
For Cantons & Municipalities:
- Use the coming months for legal preparatory work on property tax
- Clarify interdepartmental interfaces (taxes, property management, IT)
- Monitor the statement from the Conference of Finance Directors (expected 2026)
For Homeowners:
- No action required; relief will come automatically starting 2028/2030
- Optionally review tax planning for 2027 (last imputed rental value payment)
For the Federal Council:
- Decision required before summer 2026
- Balance time pressure against federal feasibility
- Clarify harmonization requirements for property tax
Indicators to Monitor:
- Publication of Conference of Finance Directors statement
- Federal Council decision on timeline (expected June/July 2026)
- First cantonal laws on property tax (starting 2027/2028)
