Property taxation in French-speaking Switzerland: what changes in 2026

Swiss property taxation is complex because it combines federal law, cantonal rules and municipal practice. For an owner or prospective buyer in French-speaking Switzerland, understanding the main mechanisms helps avoid surprises and structure a transaction lawfully. This is the position as of mid-2026.

Wealth tax and the property's fiscal value

In Switzerland, real estate forms part of taxable wealth. Each canton determines a fiscal value using its own method, usually below market value. In Geneva, the difference can vary significantly depending on the property and the date of the latest assessment. In Vaud, the official fiscal valuation also generally remains below market value.

Wealth tax is levied at cantonal and municipal level. In Geneva, the effective marginal burden can exceed 1% for substantial fortunes, which is one reason a mortgage can remain relevant even when the buyer could purchase in cash. In Vaud, the scale can be lighter in certain middle brackets.

Transfer duties on acquisition

When a property is purchased, transfer duties are levied by the canton, in addition to land-register and notarial fees.

• Geneva: around 3% of the purchase price including related charges.
• Vaud: 2.2% for the canton, plus around 0.1% land-register charges and additional fees. The total is often close to 3.3%.

These costs should be included in the initial budget on top of the purchase price.

Imputed rental value: reform is progressing

Imputed rental value remains one of the most debated aspects of Swiss property taxation. Under the current system, an owner occupying their own home declares a notional rental income, in exchange for deductions including mortgage interest and certain maintenance costs.

The reform approved in 2025 provides for the abolition of imputed rental value for primary residences, with implementation expected no earlier than 2028. Final details, including the treatment of deductions and secondary residences, are still being clarified through implementing rules. The official timetable can be followed through the Federal Tax Administration.

In practical terms, the current regime still applies in June 2026. Buyers should reflect it in their financial planning and anticipate the transition.

Property gains tax

On resale, the capital gain is taxed under a decreasing scale designed to favour longer holding periods. In Geneva, the rate falls from 50% of the gain for a resale within two years to 10% after more than 25 years. Value-adding renovation expenditure can be deductible when properly documented and compliant with tax definitions.

Vaud also applies a decreasing scale, with possible deferral in certain cases where proceeds are reinvested in a new primary residence in Switzerland, subject to strict conditions.

Wealth-planning strategies

Several fully lawful approaches are worth considering in advance:

• Calibrating mortgage leverage to optimize the combined wealth- and income-tax burden.
• Maintaining rigorous evidence of value-adding works to reduce the taxable property gain.
• Considering the municipality's tax multiplier as part of location decisions.
• Comparing direct and indirect ownership according to the buyer's profile, including residence status and international succession issues.
• Planning succession early, including through inheritance agreements and appropriate holding structures.

These matters belong with qualified tax advisers and notaries. We work with an established network of specialists and direct clients according to their individual profile.

Geneva or Vaud: how to decide?

There is no universal answer. With similar wealth and income, Vaud can be more favourable for wealth tax and certain income brackets, while Geneva offers a denser concentration of services, international schools and transport. Taxation should never be the sole location criterion, but it can materially affect decisions about use and expected holding period.

For international profiles, expenditure-based taxation, commonly known as lump-sum taxation, remains available in several French-speaking cantons, but not in Geneva, which abolished it in 2014. This should be reviewed before any move.
