The creation in 2008 of the Directorate-General for Public Finance (Dgfip) was one of the emblematic reforms of the general revision of public policies. The balance sheet makes it essential for Dgfip to undergo a genuine transformation by defining a strategy for change and by identifying the main factors that hinder, or even block, its implementation. The sharp decline in IT budgets over the past ten years has weakened already old information systems. The Dgfip has thus accumulated a “technical debt” that focuses on its modernization. The Court recommends taking advantage of digital technology to modernize service to taxpayers.
