Global tax transparency initiatives have significantly expanded the availability of financial information across jurisdictions. Instruments such as the Common Reporting Standard (CRS) and beneficial ownership registers have strengthened access to offshore financial data, offering tax administrations new tools to detect hidden wealth and cross-border tax avoidance.
However, translating this increased transparency into tangible revenue outcomes remains a challenge for many developing countries.
Drawing on African experience and evidence from ATAF’s applied research, Dr Ezera Madzivanyika, Manager for Applied Research and Statistics Division at ATAF, highlighted this persistent gap during discussions at the EU Tax Observatory Conference in Paris, where international experts examined how transparency and exchange-of-information reforms are being applied in real audit environments. While access to financial data has improved, many tax administrations still face difficulties in converting this information into effective compliance action.
Key constraints include limited technical capacity, data quality challenges, and under-resourced exchange of information (EOI) functions. These pressures are particularly evident in complex cases involving high-net-worth individuals, where specialised expertise and analytical tools are often required to identify offshore assets and enforce compliance.
These insights point to the need for a shift from transparency in principle to transparency that works in practice. Strengthening operational capacity, improving data utilisation, and enhancing the effectiveness of Exchange of Information mechanisms will be critical for tax administrations seeking to better protect their tax bases and strengthen domestic revenue mobilisation.
At the same time, sustainable tax systems depend not only on enforcement, but also on trust. Tax compliance is not driven by goodwill alone. It depends on how easy it is to comply, how costly it is not to, and above all, on public confidence in the fairness of the tax system.
When citizens see that taxes are applied fairly, that public services function effectively, and that all taxpayers contribute their share, voluntary compliance becomes stronger and more sustainable. Without trust, compliance tends to rely more heavily on enforcement rather than cooperation.
