Real estate taxation in Switzerland is a complex area that impacts every stage of a property owner's life: purchase, ownership, and sale. Good tax planning can generate significant savings over the long term.

At purchase: transfer duties vary from 0% to over 3% of the purchase price depending on the canton. Notary fees and intercalary interest during construction should be factored into the tax planning.

During ownership: the imputed rental value -- a notional income corresponding to approximately 60-70% of the market rent -- is added to your taxable income, even if you live in your own property. In return, you can deduct mortgage interest, maintenance costs (flat rate or actual costs), and building insurance premiums. The strategy is to alternate between the flat rate and actual costs depending on the year, grouping renovation work to maximize deductions.

At sale: capital gains tax on real estate (IBGI) applies to the difference between the sale price and the purchase price (including value-enhancing investments). The rate is degressive based on the holding period -- the longer you hold, the less you pay. A replacement purchase (reinvestment in another property) allows you to defer this tax.

Indirect amortization via pillar 3a allows you to maintain mortgage interest deductions while building up tax-deductible pension capital.

Our experts precisely calculate the tax impact of each option and recommend the optimal strategy for your situation.

Frequently asked questions

What is the imputed rental value and how is it calculated?
The imputed rental value is a notional income that property owners must declare, corresponding to the rent they could obtain on the market (generally 60-70% of the actual market rent). It is set by the cantonal tax authority and is added to your taxable income. In return, you can deduct mortgage interest and maintenance costs.
Is it better to deduct the flat rate or actual maintenance costs?
The flat rate generally represents 10-20% of the imputed rental value depending on the age of the building. If your actual maintenance costs (renovations, repairs) exceed this flat rate, opt for actual costs. The optimal strategy is to group renovation work into one year and alternate between the flat rate and actual costs.
How does the quasi-resident status work in Geneva?
The quasi-resident status is reserved for taxpayers subject to withholding tax in Geneva whose household earns at least 90% of its worldwide income in Switzerland. This status, obtained through a Subsequent Ordinary Taxation request (TOU), allows the deduction of actual expenses (pillar 3a, LPP buy-backs, childcare costs, alimony, etc.) instead of the flat-rate withholding tax scale. The request must be filed before of the following year. Note: since 2021, the TOU is irrevocable and applies until departure from the canton or obtaining a C permit.
What is the maximum tax rate in Geneva?
The maximum marginal tax rate in Geneva can reach approximately 44.75% when combining direct federal tax (max. 11.5%), cantonal tax, and municipal tax. This rate applies to the highest incomes and varies slightly depending on the municipality of residence. The City of Geneva applies a municipal surcharge of 45.5% of the base cantonal tax. The municipalities with the lowest tax rates in Geneva are Cologny, Collonge-Bellerive, and Vandoeuvres.

Tax Declarations (Individuals)

We prepare and optimize your tax return, whether you are an employee, self-employed, or a retiree. Our expertise covers all deductions allowed by the cantonal and federal tax authorities, in order to legally reduce your tax burden. Each declaration is reviewed by a specialist before submission.

Withholding Tax & TOU

Withholding tax is deducted directly from the salary of B permit, L permit, or cross-border workers. We analyze your situation to file a Subsequent Ordinary Assessment (TOU) request when it is advantageous, which often allows you to recover several thousand francs. Since 2021, the withholding tax reform has expanded TOU eligibility for many taxpayers.

Cross-Border Taxation

Cross-border workers are subject to complex tax rules arising from the double taxation agreements between Switzerland and France. Depending on your canton of employment, you may be taxed at source in Switzerland or only in France. We guide you to optimize your situation and avoid double taxation, taking into account the Franco-Swiss agreement of April 11, 1983 and its amendments.
