On 23 August 2018, HMRC published guidance on the effect on VAT of a no deal Brexit. The document emphasises throughout that it is unlikely, because of the mutual interests of the UK and the EU in securing a negotiated settlement, that there will be a no deal Brexit.
The purpose of the notice is to inform UK businesses of the implications for VAT rules for goods and services traded between the UK and EU member states. It outlines the impacts and gives information for businesses to take into consideration. It is worth noting that it does not cover a number of complex matters such as triangulation or warehousing but it is well worth a read through.
