Understanding the Swiss Eigenmietwert System

1. What is the Swiss Eigenmietwert and why is it taxed?

The Eigenmietwert (Imputed Rental Value / Valeur locative) is a uniquely Swiss tax concept dating back to the First World War. Swiss federal and cantonal tax law treats living in your own paid-off home as generating a fictitious income equivalent to what you would earn by renting it to a third party (typically set at 60% to 70% of market rent). This amount is added directly to your taxable gross income.

2. What deductions counteract the Eigenmietwert?

Homeowners can significantly reduce or eliminate the taxable Eigenmietwert through two primary deductions:

  • Mortgage Interest (Schuldzinsen): All interest paid on 1st and 2nd mortgages is fully tax-deductible against ordinary income.
  • Maintenance Costs (Liegenschaftsunterhalt): Owners can choose each tax year between a lump-sum flat deduction (10% of Eigenmietwert for buildings up to 10 years old; 20% for buildings older than 10 years) or deducting the actual cost of renovations, repairs, and energy efficiency upgrades.

3. What is the Cantonal Liegenschaftssteuer?

Unlike personal income tax adjustments, the Liegenschaftssteuer is an annual direct property tax levied on the official cadastral value (Steuerwert) without any deduction for outstanding mortgage debt. It is charged in approximately half of the Swiss cantons (such as Bern at up to 1.5‰ or Valais at 1.25‰) and is completely abolished in Zurich, Zug, Aargau, and Schwyz.
