Swiss Federal Tax Administration Draft on VAT Practice Rules and Temporal Effect

• New ESTV draft guidance on the temporal effect of VAT practice rulings distinguishes between first-time positions and changes to existing practice, depending on whether they arise from a law/regulation change, court decision, or the ESTV’s own review.
• For changes triggered by a law or ordinance amendment, the new VAT rule applies from the statute’s effective date only, with no retroactive application to earlier facts.
• For practice changes or new positions based on court rulings or factual/practice review: taxpayer-favorable changes apply from publication and can be claimed retroactively for still-open periods; taxpayer-adverse changes now apply uniformly only from 1 January following publication, with no retroactivity.
• Pure clarifications/editorial updates do not change substantive practice and the prior practice remains applicable.
• Written tax rulings lose binding effect when the underlying law changes at the effective date, or for court/practice-driven changes from 1 January after publication; otherwise they remain binding until formally withdrawn.
