Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what the annual costs are for the (a) systems, (b) physical infrastructure, and (c) staff for the processing of VAT for goods entering and leaving the UK from countries outside the EU.

This question was answered on 11th June 2018
When goods enter the UK from outside the EU, import VAT is applied and collected along with customs duties as part of the general customs processes. HM Revenue and Customs' import VAT costs are not captured separately. Goods leaving the UK are generally zero-rated as exports.
