Can a new concept of control under IFRS have an impact on a CCCTB?

In May 2011, new standards of the IFRS regarding concept of control and related enhanced disclosure requirements were issued. These new standards have being mandatory effective since reporting period beginning on 1 January 2013 except for countries within European Union where effectiveness begun on 1 January 2014, one year later than official date approved by the IASB. An adoption of the new standards has raised lots of questions whether a scope of a consolidation will be changed based on a new concept of the control (whether more or less entities will be consolidated). The paper provides an analysis of expectations that result from financial statements of companies traded on the Prague Stock Exchange. Together with this analysis the paper discussed an issue if a change of control concept in the IFRS can affect a use of the Common Consolidated Corporate Tax Base, which has been a great topic within the European Union. In 2011 the European Commission issued the Proposal for a Council Directive on a CCCTB and established a draft of rules how to consolidate companies within the EU for the tax purposes. Can the tax approach based on the CCCTB be affected by a change in the IFRS such as a change in the concept of control?
