In finance, we often come across the term "fiscal unity", which refers to the tax treatment of associated companies. It allows for the grouping of profits and losses, essentially treating them as the combined profits of one entity. This concept is also known as "tax consolidation" or "group taxation". It provides certain benefits for companies within the same group, such as offsetting losses against profits and avoiding double taxation. In simpler terms, it promotes a more efficient and fair tax system for related businesses.
