Switzerland reporting cycles and business-day rules
Swiss business-day cycles align with ESTV (Federal Tax Administration) Mehrwertsteuer (MWST) quarterly returns due by the last day of the month after each quarter-end (Form 0552), and PostFinance / SIX SIS interbank settlement on bank business days. The Swiss National Bank (SNB) holds Monetary Policy Assessments quarterly in March, June, September, and December. SIX Swiss Exchange trades Mon-Fri excluding the federal Swiss National Day (1 August) and Christmas/Boxing Day. Cantonal tax filings vary by canton (typically March 31 for individuals). SwissBanking and FINMA regulate the financial-services sector with quarterly listed-entity disclosure cycles.
