Detailed Summary

The Swiss Federal Authorities published on 7 January 2026 the official determination of the imputed interest rate for the current tax year. This measure is based on the legal foundation of the Tax Harmonisation Act (StHG), specifically Article 25abis paragraph 4.

The interest rate is recalculated annually and is based on the yield of ten-year Federal Bonds. The reference date is the last trading day of the calendar year preceding the tax year – for 2026, therefore the last trading day of 2025.
