The UK Finance Bill 2018 is expected to become law in 2018. The Bill will require Amazon Marketplace to block non-UK sellers who store goods in the UK from selling through Amazon.co.uk if the seller doesn’t not comply with its UK VAT registration requirements.
We recommend that you upload your UK VAT number in Seller Central before March 5th 2018 to ensure smooth functioning of your account. To learn more about VAT, please visit our VAT resources page. More details about the legislation can be found on the HMRC website.
