This legislation ratified the merger of the the Institute of Accountants and Tax Consultants (IAB-IEC) and the Institute of Accounting Professionals and Tax Experts (BIBF-IPCF), thereby creating the Institute of Tax Advisors and Accountants (ITAA). The law was implemented by royal decree on 11 September 2020. In view of the internationalisation of the profession, the institute uses an English-language name (ITAA).

The ITAA has various tasks:
