On 22 September 2026, the Swiss Federal Department of Finance (FDF) confirmed that the interest rates for federal taxes, duties, and sanctions will remain unchanged for the 2027 calendar year. The decision, published in the Federal Gazette, maintains the default interest and refund interest rate at 4.00 percent and the compensation interest for voluntary advance payments on direct federal tax at 0.00 percent. This stability extends across the entire federal fiscal spectrum, including value added tax (VAT), direct federal tax, withholding tax, tobacco tax, beer tax, automobile tax, mineral oil tax, spirits tax, customs duties, stamp duties, the performance-related heavy vehicle charge (LSVA), the CO2 levy, the volatile organic compound (VOC) levy, the supplementary tax for the minimum taxation of large multinational enterprise groups (Pillar Two), and sanctions under CO2 legislation. The FDF determined that no amendment to the Ordinance on Default and Compensation Interest Rates on Duties, Taxes, and Sanctions (SR 631.014) is required, as the current rates continue to reflect the prevailing market conditions and the Federal Council’s interest rate policy.
Key Takeaways
- Broad Rate Stability Across Federal Levies: The 4.00 percent default and refund interest rate applies uniformly to over a dozen federal tax and duty categories. This uniformity simplifies compliance for multinational groups and domestic firms that manage multiple tax obligations, as they can apply a single interest rate for late payments and refunds across VAT, customs, excise duties, and environmental levies.
- Zero Advance Payment Incentive Maintained: The 0.00 percent compensation interest on voluntary advance payments for direct federal tax continues to remove any financial incentive for early payment beyond avoiding default interest. Taxpayers should note that while advance payments do not earn interest, they reduce the principal subject to potential default interest if final assessments exceed provisional payments.
- Pillar Two Supplementary Tax Included: Notably, the interest rate regime now explicitly covers the supplementary tax under the OECD/G20 Pillar Two minimum taxation framework. This ensures that any late payment or refund interest on the top-up tax for large multinational groups is calculated at the same 4.00 percent rate, aligning domestic administrative practice with international standards.
