Value Added Tax (VAT) may be a relatively young tax, but it has become one of the most complex and fast‑moving areas of Swiss taxation. Guidance and practice evolve frequently, and VAT requirements can be difficult to navigate for non‑specialists, particularly when transactions, documentation and accounting processes must consistently support the VAT treatment applied.
Swiss VAT is a self‑assessment tax. This means that the taxpayer is responsible for determining the VAT due and the VAT to be recovered. In the event of errors, the Swiss tax authorities may reassess the VAT position, charge late‑payment interest and, where applicable, impose penalties. With a five‑year limitation period, misunderstandings or misinterpretations can lead to significant financial exposure over time.
At RSM Switzerland, our VAT specialists help organisations manage VAT risk by strengthening the link between VAT rules and day‑to‑day operations. This includes accounting, invoicing, contracts, supply chain flows and supporting documentation.
Why Swiss VAT risk management matters
Between 2024 and 2025, the VAT division of the Swiss Federal Tax Administration carried out around 27,200 VAT audits. These resulted in VAT corrections in favour of the administration of approximately CHF 640 million, while VAT refunds for registered companies amounted to around CHF 218 million.
These figures highlight the significant financial impact VAT issues can have and underline the importance of a robust VAT approach. This is particularly relevant for organisations without dedicated in‑house VAT expertise, complex business models, or international operations.
Our approach: a VAT strategy built on four pillars
Internationally active organisations face multiple indirect tax obligations, while accounting systems often embed only limited VAT logic. This can create unnecessary exposure and inefficiencies. A clear VAT strategy helps reduce risk, identify cash‑flow opportunities and introduce scalable processes that simplify compliance.
Governance & Structure
Ensuring that your corporate structures, supply chain arrangements, contractual frameworks and intercompany transactions are optimised for effective VAT management. A well‑structured organisation reduces compliance complexity and strengthens your VAT position.
Systems & Automation
Ensuring systems supporting VAT decisions and processes are properly configured and used, to reduce manual work, strengthen reliability and create scalability. Process mapping and automation identification eliminate errors and free resources.
Compliance & Reporting
Ensuring processes to review and report VAT data to the tax authorities are effective, appropriate and supported by the right technical knowledge. Robust compliance processes are the foundation of audit readiness.
Audit Readiness & Recovery
Ensuring that appropriate processes are in place to identify risks early, recover previously unclaimed VAT amounts and defend your position during audits while maintaining audit‑ready documentation.
