Integrated reporting (IR) is a new corporate‐reporting system that aims to represent the firm's value creation in the short, medium, and long term. In contrast to other disclosure systems focusing on non‐financial dimensions, including social and environmental aspects, IR is characterized by information connectivity. In recent years, integrated reporting has received increasing interest, both academic and professional. However, report quality is still a critical aspect of IR. Although several studies investigate IR, few focus on quality and its determinants. This study aims to fill this gap by investigating the impact of national culture, an external determinant, from a stakeholder theory perspective. The results show that IR quality is related to five dimensions of Hofstede—power distance, individualism, masculinity, and indulgence negatively and uncertainty avoidance positively. This study contributes to the relevant literature by analysing an additional factor that influences the quality of corporate reports, namely, national culture. This is the first study that investigates national culture as a determinant of integrated‐reporting quality.
