I buy online from the UK based Oasis clothes shop. I understand the requirement to charge VAT at the irish rate which is added to each purchase just before checking out (21%). However on their website they state "All prices shown on the website are inclusive of VAT at the current UK rates." My question is should they not be deducting the VAT at the UK rate from the items before then adding VAT at the irish rate. Or are they entitled to charge VAT twice, or do they have to charge it twice?
