Consultancy in Switzerland from UK company
I have been asked to conduct engineering consultancy in Switzerland. I work for a UK company and they are in the process of agreeing a contract with a Swiss company for the delivery of a consultant (me) to undertake tasks for the Swiss company in Switzerland. We are talking about 1-2 weeks a month for 12 months. I will also do some work on behalf of the Swiss company in the UK. I remain throughout an employee of the UK company and paid in the UK.
The Swiss company have stated that I will not require any sort of work permit or residency permit as I will not be paid by them and will only be in Switzerland for short periods; they have told me I could stay up to 90 days without any issues.
It will be just myself (family stay in the UK) and I plan on flying in and using hotels and hire cars.
Is the Swiss company correct in their statement about permits? Any gotchas with this type of arrangement?
Your knowledge and experience on this matter would be appreciated.
