Value Added Tax (VAT) is imposed by member states of the EC on nearly all sales and services within the EC. The rates vary slightly within each member state. If a seller is registered for VAT and claimed the VAT when purchasing an item, the seller must charge VAT when selling that item. Where a seller is registered for VAT and should charge VAT, then VAT must be charged by the seller even when the item is sold to a person living in another EC country. But, if the buyer is registered for VAT then no VAT is charged providing the buyer can provide his or her valid VAT number. However, special rules apply to those who are registered for the 'Flat Rate VAT Scheme' in the UK. Please see http://www.hmrc.gov.uk/vat/start/schemes/flat-rate.htm
Export Duties When an item is exported outside the EC, for example, from the UK to the USA; no VAT is charged, but the American buyer may well have to pay customs duties on import. No customs documentation is required for export within the EU. However it is likely that customs documentation will be required when exporting outside the EU. The shipping company should advise you on that.
Import Duties If an item is imported into the EC, for example from Australia to The Netherlands, then it would be liable to customs duties and VAT. If the buyer is registered for VAT, the buyer can reclaim the VAT element. We are unable to advise on import duties because they vary from country to country. We ask you contact your local customs office to ask what it will cost you.
The foregoing is a guide only. If you are registered for VAT, it is your responsibility to ensure you are complying with current regulations. You will also need to check current rates.
