The use of a common consolidated corporate tax base (CCCTB) should become mandatory after a transition period, according to the European Parliament in Brussels.
The measure was agreed by a resolution – approved by 452 votes, with 172 against and 36 abstentions – after the European Commission had proposed a voluntary scheme.
A CCCTB would give companies a single set of rules for calculating taxable profits, rather than them having to comply with differing accounting rules in each member state in which they work.
It would initially be relevant to European co-operative societies, which are by nature cross-border. After five years, the scheme would apply to all companies except small and medium-sized enterprises, which would be able opt in.
The parliament proposed that if not all member states wish to take part, those that did could introduce a CCCTB via the European Union's enhanced co-operation procedure.
As a set of rules for computing taxable income, a CCCTB does not impose common tax rates.
