Imputed Rental Value to Be Abolished in 2029 : Why Plan Your Renovations in Advance?
The reform of the taxation of owner-occupied homes is due to come into force on 1 January 2029. The imputed rental value of properties occupied by their owners will be abolished. As a general rule, maintenance costs will no longer be tax-deductible at federal, cantonal or municipal level. Different rules apply to rental properties. For homeowners considering renovation work, the type of work, its timing and its tax treatment should be carefully assessed.
Energy-Efficiency Improvements : Cantonal Decisions Awaited
From 2029, expenditure on energy-efficiency improvements, such as roof insulation, window replacement or the installation of a heat pump, will no longer be deductible from direct federal tax. However, cantons may choose to maintain this deduction until 2050 at the latest. In September 2026, the Vaud Council of State indicated its intention to preserve the deduction. In Geneva, this option was being considered in March 2025. Cantonal rules have yet to be confirmed, so future tax deductions cannot be guaranteed.
Invoices, Permits and Deadlines
Cantonal rules determine which tax year expenses can be allocated to. Completing renovation work in 2028 therefore does not guarantee that the costs will be tax-deductible. You should also check invoicing and payment dates, as well as any permits that may be required from your local municipality. Administrative procedures and contractor availability can take time. If you are planning renovation work, start preparing early and confirm the rules that apply to your specific circumstances. Not every homeowner needs to undertake renovation work before 2029, but careful planning can help avoid unpleasant surprises.

As of 1 January 2027, a new Energy Act will come into force in the Canton of Vaud. Its aim is to accelerate the energy transition and reduce the canton’s reliance on imported fossil fuels. Today, more than 80% of the energy consumed in the canton comes from outside its borders. The new law also supports Vaud’s climate objectives, including a 60% reduction in greenhouse gas emissions by 2030 and carbon neutrality by 2050 at the latest.
For property owners, the main announced measures concern :
- Oil and gas heating systems : When these systems reach the end of their service life, they will have to be replaced with renewable alternatives, in accordance with the applicable requirements.
- Large, energy-inefficient buildings : Buildings rated F or G and exceeding 750 m² will have to undergo energy-efficiency renovations by 2042.
- Solar energy : Photovoltaic installations will be required on certain new buildings and as part of roof renovations.
- Support and financial assistance : Subsidies and support measures are planned. Exemptions may be granted to take technical, heritage-related or financial constraints into account.
These changes may raise questions depending on the characteristics of your property and your renovation plans.
