The EU Budget has always been characterized by political disputes, which have mirrored the Union’s economic, social and political evolution. This chapter argues that the political debate around the EU budget composition in the 2021–2027 period reflected the state of the European project, namely an unsteady intergovernmental Union. It will discuss EU budget from procedural perspectives, identifying the intergovernmental features of budgetary policy up to the 2021–2027 period, in particular by discussing how the EU Own Resources are organized. The Lisbon Treaty consolidated numerous intergovernmental procedures in new policy areas and the EU budget is no exception. The chapter also analyses the political debate in the negotiation process both on the revenue and on the expenditure side, with potential negative consequences on European integration as a whole. Lastly, it considers the reluctance of many Member States to deepen the integration also with respect to the EU budget.
