The latest peer review results on preferential tax regimes highlight jurisdictions’ continued efforts to address harmful tax practices through the implementation of BEPS Action 5 minimum standard.
At its 65th meeting held in May 2026, the OECD Forum on Harmful Tax Practices (FHTP) applied for the first time the revised BEPS Action 5 peer review methodology. Under this approach regimes are first subject to a BEPS impact assessment to determine whether a full legislative review is needed or whether the BEPS impact is expected to be low.
The FHTP reached new conclusions on 13 regimes. For seven regimes (one from Azerbaijan, four from Fiji, one from Japan, and one from Peru), a conclusion of “not harmful” was reached and for six regimes (three from Azerbaijan, one from Malaysia, one from Peru, and one from Serbia), it was concluded that the regimes would be kept “under review”.
The total number of regimes reviewed by the FHTP since the start of the BEPS Project is now 347, with over 40% of those regimes being (or in the process of being) abolished.
