For each day on which a Swiss vehicle subject to the PSVA demonstrably travels solely abroad, the holder will be entitled to a refund of 1/360 of the annual charge. For days on which the vehicle travels both abroad and in Switzerland, the refund entitlement is halved.
Amounts of less than CHF 50 per request will not be refunded.
Refund requests are to be submitted to the Directorate General of Customs, together with the corresponding trip controls, within a year following expiry of the charge period. The Directorate General of Customs can require further evidence.
