What is the procedure for managing Value Added Tax (VAT) for orders dispatched from the United Kingdom to Northern Ireland?

This article outlines the protocol for UK merchants utilizing the IOSS scheme when dealing with orders sent to Northern Ireland.

In accordance with Brexit arrangements Northern Ireland remains to be considered as part of EU for delivery of goods from the UK. As per these arrangements all sales of goods from the UK to Northern Ireland are subject to the UK VAT. If the order value is below 135 GBP the order should be reported as an IOSS sale. Sales over 135 GBP are to be considered and treated as internal UK sale.

IOSS Northern Ireland sales are to be reported as exports in the UK VAT report (0 VAT applied) , over 135 GBP sales to Northern Ireland are reported in the UK VAT report as usual internal sales to the UK .
