The OECD Forum on Harmful Tax Practices (FHTP) has published its latest peer review results on preferential tax regimes, marking the first application of a revised peer review methodology adopted at the FHTP's 65th meeting in May 2026.
The revised approach introduces a BEPS impact assessment as an initial filter. Regimes are assessed first to determine whether a full legislative review is warranted or whether their BEPS impact is expected to be low. This tiered process is intended to concentrate scrutiny where the risk of harmful tax practices is greatest.
The FHTP reached new conclusions on 13 regimes. Seven received a finding of "not harmful": one from Azerbaijan, four from Fiji, one from Japan, and one from Peru. The remaining six were placed "under review": three from Azerbaijan, one from Malaysia, one from Peru, and one from Serbia.
Since the BEPS Project began, the FHTP has now reviewed 347 regimes in total. More than 40% of those regimes have been abolished or are in the process of being abolished.
Further detail on BEPS Action 5 is available at the OECD harmful tax practices page.
