Casatax 2026
Buying your main residence in Geneva is an important life project, where the investment must be controlled and anticipated.
Good news : the Casatax scheme is evolving again on 1 March 2026, with indexed amounts that can make a difference.
Casatax in brief
Casatax is a Geneva cantonal scheme that allows you to reduce part of the registration fees when buying a home intended to become your main residence.
New confirmed Casatax amounts for 2026
From 1 March 2026, the indexed parameters are as follows :
- Property value ceiling : CHF 1,394,928.– (vs CHF 1,374,396 in 2025)
- Registration fee reduction (sale tax) : CHF 20,924.– (vs CHF 20,616 in 2025)
- Mortgage deed rights : 50% reduction
Why are these amounts changing ?
Each year, the Casatax thresholds are indexed. For 2026, the State Council reports a variation of around +1.4%, calculated based on the Geneva construction price index (115.5 in October 2025 vs 113.8 in October 2024).
Concretely, what does this change for your project ?
- You were already comfortably below the 2025 ceiling : the impact is mainly a slightly higher saving on fees.
- Your purchase price is between CHF 1,374,396 and CHF 1,394,928 : this is the most sensitive case. Signing after 1 March 2026 may determine eligibility.
- You are above the new ceiling : Casatax does not apply, even after indexation.
Eligibility conditions
To benefit from Casatax, the property must in particular :
- Be intended to become your main residence,
- Lead you to take up residence in the property within 2 years following the transfer of ownership,
- And remain domiciled there for at least 3 years (otherwise, the advantage may be reclaimed).
