I am looking for confirmation on the matters below:
A UK company, weddings planner and vat-registered in the UK, wants to organise weddings in another EU country. My understanding is that:
It will be charged local VAT rate on purchases of materials within the other country which are not removed to the UK but used there in its activities. So, it will not be able to claim back the VAT in the UK.
Place of supply for wedding planning/organisation is in the country in which the event takes place and hence the UK company is liable to register for VAT in the other country. That means of course dual VAT registration (UK for UK sales). The only way to avoid that, is by describing the service it provides as consultancy (in that case normal rules apply ie place of supply is the UK.
If required to register in the other EU country, it will also be able to claim back vat on purchase of goods in the other country.
