29/07/2026 – The Global Forum on Transparency and Exchange of Information for Tax Purposes (Global Forum) has published three new peer review reports on transparency and exchange of information on request (EOIR) for tax purposes for the Cook Islands, Namibia and Tanzania. The reports were approved by the Global Forum’s Peer Review and Monitoring Group in June 2026 and subsequently adopted by the Global Forum members. All three jurisdictions were rated overall as “Largely Compliant” with the EOIR standard.
Since 2016, 135 jurisdictions have been fully reviewed by the Global Forum and the ratings assigned are positive: 91% of the jurisdictions are rated “Compliant” or “Largely Compliant” with the standard, 6% are assessed as “Partially Compliant”, and 3% as “Non-Compliant”.
A summary of the jurisdiction-specific findings and recommendations are as follows:
The Cook Islands joined the Global Forum in 2009. In this second review of its EOIR practice, it maintains its Largely Compliant rating. The Cook Islands has made a number of improvements to its transparency framework, designed to strengthen the availability of legal and beneficial ownership information under both its anti-money laundering framework and company law. The coverage of these frameworks and a robust supervision of the international financial sector have ensured the Cooks Islands is equipped to satisfy requests for information related to that sector. While exchange of information on the domestic sector has rarely been necessary, some areas for improvement were identified to ensure the availability of information in all cases. The Cook Islands is also recommended to further strengthen its supervision and enforcement of laws relied upon to ensure the availability of ownership and identity information, as well as accounting information. The Cook Islands has shown improvements since its previous review in the quality and timeliness of responses to requests from exchange partners. Access the report
Namibia joined the Global Forum in 2019. In this first full assessment, Namibia is rated as overall Largely Compliant with the EOIR standard. Namibia’s legal and regulatory framework contains requirements relating to the availability of legal and beneficial ownership, accounting and banking information. The peer review report points to areas for improvement, including the availability of information where nominee arrangements are used, the retention of records when a bank ceases its operations in Namibia, as well as ensuring the confidentiality of the exchanged information. Since commencing exchanges in 2022, Namibia has strengthened its practices, demonstrating notable improvements in the timeliness of exchanges. Continued efforts in this direction are encouraged to ensure further progress. The supervision of entities with respect to their tax and beneficial ownership reporting requirements are also noted as important areas of improvement. Access the report
Tanzania joined the Global Forum in 2015. In this first full assessment, Tanzania is rated as overall Largely Compliant with the EOIR standard. Tanzania’s legal and regulatory framework generally provides for the availability of legal and beneficial ownership information, accounting information and banking information in mainland Tanzania and Zanzibar. Some gaps are noted in respect of nominee arrangements, bearer share warrants in Zanzibar and in the definition of beneficial ownership and ensuring such information is kept up-to-date. Tanzania also needs to further implement its supervisory and oversight mechanisms to check non-compliance in ensuring the availability of legal and beneficial ownership and accounting information. Due to its small treaty network, Tanzania’s EOIR experience has been limited, but this may change, especially as it works towards broadening its exchange relationships. The report also notes that Tanzania needs to monitor its organisational resources and processes to ensure effective exchange of information. Access the report
