On 7 September 2026, the Swiss Federal Tax Administration (ESTV) released the annual update of the ICTax price lists and free share lists for the valuation years 2024, 2025, and 2026. ICTax (Interactive Tax) serves as the centralized, electronic valuation database mandated by the Swiss Tax Conference (SSK) and used uniformly across all 26 cantons for wealth tax and income tax assessment of securities, collective investment schemes, and employee participation rights. The platform operates under the legal framework of the Federal Act on Direct Federal Tax (DBG) and the respective cantonal tax laws, which require taxpayers to declare assets at fair market value. The ESTV, in collaboration with SIX Financial Information and the Swiss Funds & Asset Management Association, compiles year-end prices, corporate action adjustments, and free share valuations based on the Federal Supreme Court’s established methodology. This year’s update incorporates the 2024 year-end closing prices, the 2025 interim valuations, and the preliminary 2026 data, ensuring that tax assessments for the 2025 tax period (filed in 2026) and the upcoming 2026 tax period (filed in 2027) reflect current market conditions. The release also aligns with the revised OECD Common Reporting Standard (CRS) and the Swiss implementation of the Automatic Exchange of Information (AEOI), which rely on consistent securities valuation for cross-border reporting.
Key Takeaways
- Comprehensive Valuation Updates: The 2026 ICTax release includes revised price lists for all three years 2024, 2025, and 2026, reflecting year-end market prices, dividend adjustments, stock splits, and capital changes. The price lists cover approximately 45,000 Swiss and foreign securities listed on SIX Swiss Exchange and major international exchanges, as well as over 12,000 collective investment schemes authorized for distribution in Switzerland. For each security, ICTax provides the official year-end price, the tax value (which may differ due to valuation discounts for unlisted shares), and the applicable withholding tax status. The free share lists for employee participation plans have been updated to incorporate the latest Federal Supreme Court rulings on valuation discounts for vesting periods, transfer restrictions, and performance conditions. Specifically, the 2026 update introduces a new category for performance-based share units with multi-year vesting, applying a discount factor derived from the Black-Scholes model as endorsed by the Court in its 2025 precedent decision. Taxpayers holding restricted stock units (RSUs) or employee stock options (ESOPs) granted by Swiss or foreign employers must apply these updated discount factors when declaring the taxable benefit in their annual tax return.
- Mandatory Use for Tax Returns and Compliance Implications: Cantonal tax authorities require taxpayers to apply ICTax valuations when declaring securities in wealth tax returns and when reporting income from employee share plans. The Swiss Tax Harmonization Act (StHG) and the implementing cantonal laws stipulate that the ICTax values constitute the legal presumption of fair market value. Deviations from ICTax values are only permitted if the taxpayer provides an independent expert opinion demonstrating a material discrepancy, which significantly increases the compliance burden for holders of non-standard or illiquid holdings. For the 2025 tax assessment period, the updated 2024 year-end values are binding; for the 2026 period, the 2025 values apply. The ESTV has also clarified that the ICTax free share valuations must be used for the qualification of employer contributions under the voluntary pension scheme rules (Article 50 DBG) and for the calculation of the net wealth tax base. Failure to apply the updated values may trigger automatic audit flags in the cantonal e-tax systems, leading to requests for justification and potential penalties under the Tax Administrative Act (VwVG).
- Digital Filing Integration and Cross-Border Reporting: The updated ICTax data is directly integrated into the e-tax filing systems of all 26 cantons, enabling automated plausibility checks and pre-filled tax returns for securities held at Swiss custodian banks. Taxpayers and advisors should verify that their tax software imports the latest ICTax version before submitting 2025 tax returns due in 2026. The release also supports Switzerland’s obligations under the Automatic Exchange of Information (AEOI) and the OECD Common Reporting Standard (CRS), which require financial institutions to report the year-end value of financial accounts. Consistent securities valuation between ICTax and AEOI reporting reduces the risk of discrepancies that could trigger mutual agreement procedures under double taxation treaties. Additionally, the ESTV has published a technical interface specification (XML schema) for third-party software providers to ensure seamless data import. The next scheduled update is expected in September 2027, covering the 2027 valuation year.
