VAT is an indirect tax on consumption. A business adds it to its services, collects it, and passes it on to the federal government. Since 2024 the standard rate is 8.1 %, the reduced rate for everyday goods (e.g. food, books, medicines) is 2.6 %, and the special accommodation rate is 3.8 %. The input tax the business itself paid can be deducted, so only the value added is actually settled.
The process: after each accounting period, turnover and input tax are taken from the bookkeeping, transferred into the FTA form (today usually online via ESTV SuisseTax), and the amount owed is paid. Under the effective method you file quarterly; under the simplified net-tax-rate method, twice a year. The filing deadline is 60 days after the end of the period, followed by payment. Late filing triggers default interest.
The return is relevant for every VAT-liable business, i.e. from CHF 100,000 turnover, and from CHF 250,000 for certain associations and non-profits. Businesses below the threshold may register voluntarily, which pays off when large investments with input-tax deduction are planned. The choice between the effective method and the net tax rate has a real impact on effort and tax burden and should be made carefully at the outset.
What to watch for: cleanly separated revenue accounts per tax rate, correct treatment of foreign turnover (exports are tax-exempt but still must be declared), own consumption and private shares (e.g. a company car). Errors in input tax or wrong rates surface during an FTA audit and get corrected retroactively.
A fiduciary office usually prepares the return directly from the ongoing bookkeeping. As a guide, a single VAT return costs around CHF 150–400 depending on document volume and method; hourly rates for fiduciaries run roughly CHF 120–180 (no guarantee).
