Added value determination and added value levy
In the case of real estate, added value is created through planning measures. We assess and calculate the added value levy for municipalities and cantons under the Swiss Spatial Planning Act (RPG) and support you in the levy process for your private investment as required.
Holistic support for investors in added-value levy processes.
Regional market knowledge, regulations, and project-specific characteristics are taken into account, enabling balanced evaluation and development solutions for all parties.
Together with Häusermann + Partner, Wüest Partner has developed a digital platform for Switzerland that provides tools for calculating value-added levies and answering frequently asked legal and procedural questions.
Added value compensation is an integral part of spatial planning. Wüest Partner has developed a reliable methodology for calculating added value.
This approach enables the precise assessment of individual projects, sites, and properties through project- and site-specific evaluations. For the public sector, our calculation model serves as a reliable, independent, and binding basis for determining value-added levies.
We prepare strategic stock and demand assessments for public-sector clients, which serve to quantify future land needs.
The estimation of additional demand is based on comparing the extent of existing building zone areas with future land requirements. On this basis, we develop solution strategies to provide the necessary areas and evaluate potential for densification and conversion as required.
Our model calculations allow us to forecast the potential added value that municipalities or cantons can expect from zoning changes, upzoning, or rezoning.
The public sector can use these calculations for local planning revisions and financial planning.
Advice and calculations on all relevant tax types and subsidies
Taxes play a key role in all transactions in the real estate sector. Particularly in the case of portfolio transactions and company transfers, there is usually plenty of scope for optimization. We clarify your questions, help you gain an overview of Switzerland’s federal tax landscape, and calculate the expected tax consequences as well as any tax burdens that may be transferred to the buyer.
Additionally, we assess how measures such as energy-efficient renovations could help you benefit from potential subsidies or tax reliefs.
- Property tax (levied in approx. 50% of cantons)
