Some more twists; - If you do distance selling(=mail order, ecommerce) from UK and lets say you've got lots of Finnish customers

1. B2C to Finns using UK vat up till 35000 euros of sales

2. Once you pass that 35ke distance selling threshold you need to register for VAT in Finland and start applying Finnish VAT to your goods.
