Abstract The need for a fiscal union in the EU is an issue which has been debated many times and about which much has been written. However, the economic and financial crisis we have experienced in recent years has cast doubt on whether we have taken this debate in the right direction. Sometimes we tend to focus the debate on marginal issues and unrealistic proposals. Rather than helping us to move forward, this paralyses the EU and distances us from feasible targets. This article aims to give a general overview of the debate on a fiscal union to find out where we are in the process of fiscal integration and what we can really expect from it.
