Tax consolidation
Tax consolidation, or combined reporting, is a regime adopted in the tax or revenue legislation of a number of countries which treats a group of wholly owned or majority-owned companies and other entities (such as trusts and partnerships) as a single entity for tax purposes.
 This generally means that the head entity of the group is responsible for all or most of the group's tax obligations (such as paying tax and lodging tax returns).
 Consolidation is usually an all-or-nothing event: once the decision to consolidate has been made, companies are irrevocably bound.
 Only by having less than a 100% interest in a subsidiary can that subsidiary be left out of the consolidation.
