Technological advances make it possible to quickly access and share personal data and information, which demands greater security and requires conscious attitudes from the different professionals who deal with these issues. Accounting professionals stand out in this universe for being responsible for customer, supplier, and employee data. The information insecurity scenario led to the creation of the General Data Protection Law (GDPL), a specific legislation for personal data handling. Driven by this context, this research aimed to analyze the GDPL compliance determinants among accounting professionals. In order to achieve this purpose, we conducted a quantitative, descriptive, survey study. For data collection, we developed and applied an online questionnaire addressed to accounting professionals. The final surveyed sample totaled 194 respondents. We performed the data analysis through Structural Equation Modeling. The validated model showed the dimensions of personal behaviors and attitudes and governance mechanisms as determinants, explaining 26.3% of GDPL compliance. This research contributes to the understanding of behavioral aspects of accounting professionals in face of the new legislation. It is an unprecedented approach and fills a gap in the accounting area, presenting useful contributions for educational institutions, class associations, and companies in the area.
