Real Estate Taxation in Geneva: 2026 Guide and Reforms
The Geneva real estate landscape in 2026 is marked by regulatory stability while preparing for major structural changes. For owners and investors, mastering current rules is essential to secure the management of their assets.
Imputed rental value in Geneva: A system maintained until 2029
In 2026, the taxation of imputed rental value remains a reality for owner-occupiers. This theoretical income, calculated based on surface area, layout, and location, remains taxable. The Geneva Council of State carries out an annual indexation of this value. This system remains in force until December 31, 2028.
Towards a historic reform on January 1, 2029
The abolition of the taxation of imputed rental value, accepted by the Swiss people on September 28, 2025, will enter into force on January 1, 2029, a date confirmed by the Federal Council on April 1, 2026. From 2029, owners will no longer have to declare fictitious income for their primary or secondary residence. In return, the deduction of maintenance costs will be abolished for owner-occupied housing, while rules regarding the deduction of passive interest will be restricted, with specific provisions for first-time buyers.
Real estate taxation: Optimization levers
In Geneva, local direct taxation remains a point of vigilance. Owners can rely on several levers:
- The deduction of passive interest, within legal limits.
- Investments in energy renovation, strongly encouraged by cantonal subsidies.
- Accelerated depreciation, subject to accounting justification before the end of the fiscal year.
Land use planning and regulatory constraints
Real estate development in Geneva is strictly governed by development zones and local neighborhood plans (PLQ). Land scarcity requires qualitative densification, where each project must meet high energy performance requirements (THPE). For OAKS GROUP, this constraint is a driver of innovation: we prioritize projects that integrate these standards from the design stage to ensure the durability and market value of assets.
Key takeaways
- Imputed rental value remains taxable in 2026, 2027, and 2028.
- The abolition of the imputed rental value is set for January 1, 2029.
- The 2029 reform will eliminate the deduction of maintenance costs for owner-occupied properties.
