The OECD will publish its annual overview on corporate tax systems and multinational enterprises’ tax and economic activities on 25 November 2025.

Corporate Tax Statistics 2025 provides data on corporate tax systems in more than 170 countries and jurisdictions worldwide, including statutory and effective tax rates, withholding taxes and tax treaties, corporate tax revenues and detailed information on multinational enterprises’ (MNE) international activities.
​
The 2025 edition contains a new disaggregation of country-by-country reporting data by MNE group size, as measured by unrelated party revenues and by tax jurisdiction. New data on hybrid mismatch arrangements and mandatory disclosure rules, as well as an expansion in the coverage of the data on effective tax rates, are also included.

On 17 November 2025, the OECD released the Tax Administration Report, 2025.

The 2025 edition takes a closer look at national-level tax administrations across 58 jurisdictions.
​
Drawing on data and information from a broad set of national tax administrations across the globe, the report is intended to help tax administrations understand global trends in the design and administration of tax systems and to facilitate cross-border comparisons. 

On November 5, 2025, the Swiss Federal Council adopted the dispatch on the tax treaty with Zimbabwe.

The tax treaty will create legal certainty for the further development of bilateral economic relations and tax cooperation between the two countries. It largely corresponds to the OECD Model Convention and standard Swiss practice.
​
The treaty also takes account of the outcomes of the OECD's base erosion and profit shifting project. In particular, it provides for an anti-abuse clause that is intended to prevent a person who is resident in neither Switzerland nor Zimbabwe from claiming benefits provided for in the treaty. 

The Board of Taxation, Australia, has redesigned the Voluntary Tax Transparency Code (VTTC).

The VTTC is a set of principles and minimum standards. It encourages entities to disclose their tax information.
​
While voluntary, the Board has encouraged businesses to adopt the VTTC.

The OECD has released a new batch of updated transfer pricing country profiles.

The new batch reflects the current transfer pricing legislation and practices of 25 jurisdictions, and includes, for the first time, the profiles of Cabo Verde, Guatemala, Thailand, United Arab Emirates, and Zambia.
​
This third batch of country profiles present new information on country-specific legislation and practice regarding the transfer pricing treatment of hard-to-value intangibles and the simplified and streamlined approach for baseline marketing and distribution activities. 

The Brazilian government has signed the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting, also known as the Multilateral Instrument (MLI). 

The MLI was developed by the OECD in 2016, following the  recommendations outlined in the Action 15-Final Report of the BEPS Project (Base Erosion and Profit Shifting), an initiative by the OECD and the G20. 

This voluntary instrument is designed to modernize double taxation agreements (DTAs) worldwide. With this initiative, Brazil joins 105 other countries that have already signed the MLI.

The United States and Hungary are planning to reinstate the tax treaty between the two countries.

A meeting in this regard took place on October 17.
​
The tax treaty between the two countries was terminated in 2022.

The OECD has published a report that takes stock of the progress made in implementing the BEPS measures and the economic impact these changes have had.

The report shows how the BEPS project has changed the conversation on international tax and established new expectations for corporate responsibility and transparency, strengthening collaboration between tax authorities and enhancing tax certainty through the definition and co-ordinated application of common international tax rules.
​
The report was prepared by the Inclusive Framework ahead of the October 2025 meeting of G20 Finance Ministers and Central Bank Governors under the South African G20 Presidency.

The EU Council confirmed the EU list of non-cooperative jurisdictions for tax purposes without changes.

The new list consists of the same 11 jurisdictions as before.
​
These jurisdictions are: American Samoa, Anguilla, Fiji, Guam, Palau, Panama, Russia, Samoa, Trinidad & Tobago, US Virgin Islands, and Vanuatu.

The Barbados Revenue Authority is going to be making changes to the Economic Substance Act, according to Minister of Energy and Business, Senator Lisa Cummins.

Cummins made the statement at the media launch of Global Business Week 2025, at the CIBC Caribbean Warrens Great House, Warrens, St. Michael.

Cummins told her audience: “There is underway now a process of regulatory reform. You’ve seen much of this happening since last year January, when we had the corporation tax reform. And I’m happy to share with you, if it has not already hit your desk, that the Economic Substance Bill is going to be coming up for consultation on some changes that are going to come down the pipe.”
​
“Together with the International Business Unit and the Barbados Revenue Authority, we are going to be making some changes to the Economic Substance Act, and that will change a number of the ways in which we move from being a nominal tax jurisdiction to being a preferential tax jurisdiction, and that will have significant implications, in a positive way, for the global business sector.”

The OECD has released the latest annual peer review results on the implementation of BEPS Action 13 on Country-by-Country Reporting covering 142 Inclusive Framework on BEPS members.

The eighth peer review of BEPS Action 13 assesses how jurisdictions are implementing the Country-by-Country (CbC) Reporting minimum standard as of April 2025 and highlights continued progress in strengthening tax transparency. 

The BEPS Action 13 peer review is an annual process, and the next peer review report will be released in the third quarter of 2026.
​
The report may be viewed on the OECD’s website.

A Member of the European Parliament (MEP), João Oliveira, has tabled a motion for a European Parliament resolution on the need to improve tax fairness and ban tax havens.

The motion calls on the Member States to introduce mandatory reporting of transfers to countries, territories and regions with clearly more favorable preferential tax regimes.

The motion urges the Council and the Member States to work together at EU and international level to ban transactions to countries, territories and regions with clearly more favorable, non-cooperative preferential tax regimes.
​
Finally, the motion urges the Commission and the Council to create the conditions for tax havens to cease to exist and calls on the Member States to tax wealth where it is generated, improving tax fairness.

Bermuda’s Corporate Income Tax Agency (CITA) has launched a public consultation to gather stakeholder feedback on the second set of proposed technical amendments to the Corporate Income Tax Act 2023 (“the CIT Act”).

These amendments aim to clarify specific provisions and improve alignment with the OECD’s GloBE Rules.

CITA has already considered some stakeholder feedback and incorporated relevant changes into the draft legislation. Through this consultation, the Agency seeks further feedback on the revised draft and suggestions for any additional guidance needed to support implementation.
​
The consultation period will run from September 12-26, 2025. 

The OECD released today 36 new peer review results under BEPS Action 14 on Mutual Agreement Procedures (MAP), highlighting continued progress by members of the Inclusive Framework on BEPS that have committed to implementing the Action 14 minimum standard, which seeks to improve the resolution of treaty-related disputes through the MAP. 

The new Assessment Methodology for the Action 14 peer reviews includes a simplified peer review process, for jurisdictions that do not have 'meaningful MAP experience,' allowing them to set up a more robust MAP program in response to a possible increase in cases in the future.
​
It also includes a full peer review process, for jurisdictions considered to have 'meaningful MAP experience’ for continued monitoring purposes. 

Indian Finance Ministry has prepared a new Income Tax Bill, 2025 to be tabled before Parliament.
