Retail schemesI168
The Commissioners may refuse to permit the value of taxable supplies to be determined in accordance with a scheme if it appears to them—
a
that the use of any particular scheme does not produce a fair and reasonable valuation during any period,
b
that it is necessary to do so for the protection of the revenue, or
c
that the retailer could reasonably be expected to account for VAT in accordance with regulations made under paragraph 2(1) of Schedule 11 to the Act.
