Hi, we provide marketing consultancy via social media to a company based in Switzerland. Place of supply is the UK, so do we charge VAT on our invoices or not?
Hi - have a good look at sections 12 and 13 VAT notice 741 'Place of supply of services'.
Consultancy/market research etc are services that come within the schedule 5 para 1-8 rules - services that can be deemed to be supplied in a customers country. The flow chart in section 12 (12.9) will direct you to 'place of supply is outside EC' - so no VAT.
Having said that, I'm not really sure what you mean by 'social media'. But the above rules apply to standard consultancy work, but read the sections for exclusions.
