Guide

Real estate

Anyone who owns residential property encounters special rules in the tax return. This guide gives an overview of the most important topics.

In brief

Owners pay tax on the imputed rental value, can deduct maintenance costs and must take the property gains tax into account when selling. Additional reporting obligations apply to properties abroad. The exact rules differ from canton to canton, which is why it is worth consulting the cantonal guidelines.

What matters

  • Imputed rental value and maintenance

    The imputed rental value is added as notional income, while maintenance costs and, in some cases, energy-related investments can be deducted. You can usually choose between actual costs and a lump sum.

  • Selling a property

    When you sell, the cantonal property gains tax is generally due, which captures the increase in value. The decisive factors are the purchase price, value-enhancing investments and the holding period.

  • Real estate abroad

    Properties abroad must be declared in the Swiss tax return, even if they are taxed abroad. They have an effect through the progression proviso.

  • Energy-related renovations

    Investments in energy efficiency and environmental protection can be claimed for tax purposes under certain conditions. The specific rules are regulated differently in each canton.
