Follow the UN tax agenda — what is being negotiated, why it matters for the GCC, and what comes next.
A live policy-monitoring hub for the UN Framework Convention negotiations, its two early protocols and selected UN Tax Committee work. Draft text, negotiating positions and committee guidance are kept separate from binding domestic law.

UN Tax Committee Thirty-third Session
Convention, protocols, treaty policy and selected UN Tax Committee workstreams.
Agenda map
The watch is selective: a UN tax workstream is included when it can materially affect GCC tax policy, treaty strategy, cross-border business or tax certainty.

A five-second view of where the current UN Tax Watch workload is concentrated. Zero means the lane remains monitored but has no active source-backed file in this watch set.

Evolving records
Negotiation does not equal adoption, and adoption does not equal GCC domestic effect. The timeline keeps those stages distinct.
The UN Intergovernmental Negotiating Committee is negotiating a Framework Convention on International Tax Cooperation together with two early protocols. The process runs from 2025 to 2027 and moved into negotiation of concrete draft text at the Fifth Session in August 2026.
At the Fifth Session in New York from 3 to 13 August 2026, Member States began negotiating draft legal text across the Convention and both early protocols.
The Convention can influence the architecture of international tax cooperation, including how future standards are developed, how taxing-rights questions are framed and how new protocols interact with existing tax treaties and institutions.
High strategic relevance for GCC governments and multinational groups because GCC jurisdictions combine significant inbound and outbound investment, broad treaty networks and increasing engagement with global minimum-tax and tax-certainty frameworks. No negotiating outcome is treated as GCC domestic law unless separately implemented.
The Sixth Session is scheduled in Nairobi from 30 November to 11 December 2026. Three further substantive sessions are planned for 2027, with final texts targeted for submission to the General Assembly in 2027.
Forward view
Only official dates or official month-level timing appear here. If the UN has not announced a day-level date, Tax & Markets does not invent one.
The digitalized-economy subcommittee's focused evaluation report is due for Committee approval no later than this session; exact session dates are not stated on the current official page.

Official UN sourceTax & Markets coverage
Only real T&M coverage that explicitly matches a UN workstream is linked here; broad international-tax categorisation alone is not enough.
Qatar's Supreme Judiciary Council and General Tax Authority signed a memorandum to strengthen institutional coordination and electronic connectivity. The GTA says it will support shared judicial committees, including the Tax Grievance Committee.
UN Tax Watch reports negotiating and committee work as international policy processes. Draft convention text, protocol proposals and UN Tax Committee guidance are never presented as automatically changing the law of Qatar, the UAE, Saudi Arabia or another GCC jurisdiction.
The General Assembly established the Intergovernmental Negotiating Committee and the mandate to draft the Convention and two early protocols.
Official UN sourceThe process completed the major scoping phase and moved toward preparation of zero drafts for the Convention and early protocols.
Official UN sourceThe Committee began the first session centered on concrete draft legal text across all three workstreams.
Official UN sourceThe August negotiating round concluded after detailed discussion of the draft Convention and both protocols.
Official UN sourceThe next substantive negotiating session is officially scheduled in Nairobi.
Official UN sourceThe first early protocol addresses taxation of income derived from the provision of cross-border services in an increasingly digitalized and globalized economy. The Fifth Session moved the file from options and scoping into article-by-article negotiation of draft text.
During the August 2026 Fifth Session, Member States debated the draft protocol's scope, taxes covered, nexus and interaction with existing bilateral treaty frameworks.
The protocol could affect source-country taxing rights over cross-border services and the way service income is treated when existing bilateral treaties do not fully address newer business models.
Potentially material for GCC economies with major cross-border services, regional headquarters, financial, technology and professional-service activity. The final interaction with existing GCC treaty networks will be especially important and remains under negotiation.
Continue monitoring revised negotiating text and the Sixth Session in Nairobi from 30 November to 11 December 2026. Tax & Markets will not infer final taxing rights before the protocol text is agreed and domestic/treaty effect is separately established.
The Workstream II Co-Lead issued an options paper on taxation of services ahead of the Fourth Session.

Official UN sourceThe next substantive INC session is scheduled in Nairobi.
Official UN sourceThe second early protocol addresses prevention and resolution of tax disputes. Earlier work examined treaty-based disputes, possible mechanisms for prevention and resolution and limited approaches to certain no-treaty situations; a draft protocol moved into negotiation at the Fifth Session.
The Fifth Session placed concrete draft text for the dispute protocol before Member States as part of the August 2026 negotiating round.
Dispute architecture affects tax certainty, competent-authority processes and the ability of governments and taxpayers to resolve cross-border double-tax and interpretation disputes efficiently.
Directly relevant to GCC jurisdictions expanding treaty networks and seeking investment certainty. Any new UN mechanism will need to be assessed against existing mutual agreement procedures, domestic dispute routes and treaty commitments in each GCC jurisdiction.
Monitor revised draft text and the Sixth Session in Nairobi. Particular GCC-sensitive questions include optionality, interaction with bilateral treaties, implementation capacity and whether any mechanism creates new obligations beyond existing treaty frameworks.
The Workstream III Co-Leads issued a concept note on potential dispute-prevention and dispute-resolution solutions.
Official UN sourceMember State discussion informed the drafting phase for the dispute protocol.
Official UN sourceThe Fifth Session opened with concrete draft text for both early protocols.
Official UN sourceThe next substantive INC session is scheduled in Nairobi.
Official UN sourceThe UN Tax Committee's subcommittee is evaluating whether the 2025 UN Model adequately addresses services permanent establishments and services connected with emerging technologies such as artificial intelligence, machine learning and the internet of things.
The subcommittee mandate requires an evaluation report for Committee approval no later than the Thirty-third Session in October 2026.
Changes to the UN Model or related guidance can influence treaty negotiations, services taxation and the treatment of digitalized business models, particularly for capital-importing and source jurisdictions.
Relevant for GCC treaty policy because GCC jurisdictions use bilateral treaties to support investment while also managing source-country taxation of services. Any future UN Model change would still require treaty-level or domestic implementation before affecting taxpayers.
Watch for the Thirty-third Session in October 2026 and publication of the evaluation report. No exact session dates are stated on the current official subcommittee page, so Tax & Markets does not invent a day-level deadline.
