Why Your Geneva Renovation Must Start Before 2029
Swiss voters abolished the valeur locative tax on September 28, 2025. By January 1, 2029, the renovation deductions that go with it will also disappear.
For Geneva homeowners, this creates a narrow window: you have until December 31, 2028 to complete renovation work and claim tax deductions. Once 2029 arrives, federal renovation deductions vanish entirely.
What is the valeur locative, and why does the 2028 deadline matter?
Until now, Swiss property law taxed owner-occupants as if they were renting their homes to themselves. The government assessed a fictional rental income (typically 60–70% of market value) and you declared it every year. The fairness of this system has been debated for decades — and Swiss voters finally decided to end it in 2029.
The trade-off you lose: renovation, maintenance, and energy-efficiency costs that you've been deducting from your taxable income. After 2028, those deductions disappear at federal level. This is the critical fact property owners are missing.
How much tax can you save before the deadline?
The math is straightforward and powerful. If you invest CHF 150,000 in a major Geneva renovation before December 31, 2028, and your marginal tax rate is 35%, you save approximately CHF 52,500 in taxes. After 2028, identical renovation work provides zero federal tax benefit.

This is not a technical adjustment. It's one of the largest shifts in Swiss property taxation in a generation.
Does Geneva offer any additional time for energy renovations?
Yes — and this is valuable. Geneva canton has confirmed that deductions for energy-efficiency work (insulation, heating upgrades, solar, etc.) will remain available at cantonal level until December 31, 2030. That gives local owners a two-year extension for green renovation projects beyond the federal deadline. However, federal deductions end with 2028, and you must plan accordingly.
Energy renovations qualify for additional Geneva cantonal deductions through 2030, but federal deductions disappear at end of 2028. Plan your timeline with both deadlines in mind.
Why must you start your project now, not in 2027?
The renovation sector across Switzerland is already anticipating a surge through 2028 as property owners rush to beat the deadline. In Geneva's competitive market, this means permits, contractors, material sourcing, and architectural approvals all take time — typically 8 to 14 months from start to finish. If you wait until 2027, you risk missing the completion deadline or facing inflated contractor costs.
Starting your project today gives you a realistic window to design, obtain permits, hire contractors, complete work, and properly invoice everything by year-end 2028. Waiting even one year creates serious risk.
Permits and contractor scheduling typically require 8–14 months. If you start in 2027, you may not finish in time. Begin planning now.
How should you approach your renovation timeline?
Start with a feasibility study and architectural concept this year. Prepare your permit applications over the next 6 months. Secure your contractor commitments and material orders 12–14 months before your planned completion date. As Geneva architects, we guide clients through every phase: initial design, permitting, contractor selection, and on-site supervision — ensuring your project meets the 2028 deadline while delivering the quality your home deserves.
