On Wednesday members of the economic affairs committee will have their say about the creation of a single set of corporate tax rules. Already in 2016 a temporary parliamentary committee researching how to tackle tax evasion called on the European Commission to put forward proposals for a common set of rules that companies operating in the EU could use to calculate their taxable profits instead of having to follow different rules for each EU country they are located in. This common set of rules is known as the Common Consolidated Corporate Tax Base.
