Ethan here, born in New Zealand, grew up in South Africa and now just moved to London!
My company, VATGlobal, assists event/conference organisers, who are running events outside the UK, with their foreign VAT registrations and compliance. If you are running an event outside of the UK and are charging admission, chances are you need to account for VAT in that country.
If you are not even sure if you need my help, get in contact and I will be able to chat regardless.
Super happy to help any community member navigate through the often murky VAT waters!
