VBNB34000 | VAT Business and Non-Business: Principles: Agreeing an Apportionment Method
From HM Revenue & Customs · VAT Business/Non-Business Manual
Businesses do not have to get HMRC’s approval for apportionment, however where businesses do ask for approval, HMRC will consider whether:
The result is fair and reasonable because the indicator of non-business activity on which the method is based gives a fair reflection of the balance between business and non-business activities.
The indicator on which the method is based will reflect changes in the proportionate extent of the business and non-business activities.
The method can be easily applied by the business and audited by HMRC or is instead overcomplicated and prone to error.
Approval will normally be given if:
HMRC is satisfied that the method is soundly based.
the business does not make exempt supplies.
The method will be approved on the basis of the current levels and profile of business and non-business activities. The method may no longer give an accurate apportionment if either of these change to a material extent.
Combined BNB/PE Method
From 1 January 2011, if a business has non-business activities and makes both taxable and exempt supplies, it may request to use a combined business/non-business and partial exemption method.
