Overview.  As discussed in prior blog posts, Amount A is a proposed new taxing right over a share of residual profit of MNE groups that fall within its defined scope.  The calculation and allocation of Amount A will be determined through a formula that is not based on the Arm’s Length Principle (ALP).  The formula will apply to the tax base of a group (or segment where relevant) and will involve three components:  Step 1:  a profitability threshold to isolate the residual profit potentially subject to reallocation;  Step 2: a reallocation percentage to identify an appropriate share of residual profit that can be allocated to market jurisdictions under Amount A (the “allocable tax base”); and Step 3: an allocation key to distribute the allocable tax base amongst the eligible market jurisdictions (i.e. where nexus is established for Amount A).  This three-step formula to determining the Amount A quantum could be delivered through two approaches:  a profit-based approach or a profit margin-based approach.  A profit-based approach would start the calculation with the Amount A tax base determined as a profit amount (e.g. an absolute profit of EUR 10 million) whereas a profit-margin approach would start the calculation with the Amount A tax base determined as a profit margin (e.g. a PBT to revenue of 15%).  Both approaches would apply the three steps of the allocation formula similarly, and hence would deliver the same quantum of Amount A taxable in each market jurisdiction.
