International Tax Governance: Trends and implications for the international air transport industry
At a glance
- ICAO's residence-based taxation principles for international air transport, adopted for over 50 years, face threats from emerging multilateral tax initiatives and revisions to UN Model Tax Conventions.
- 2025 UN Model Tax Convention revision shifted from residence-based to source-based taxation as preferred principle, creating risk of double taxation and administrative complexity for airlines operating globally.
- Current international tax governance lacks mechanisms to prevent overlapping rules, conflicting interpretations, and does not account for specific operational realities of sectors like aviation.
- Air transport's high operational fungibility—mobile aircraft, revenue not tied to single locations, global network effects—weakens logic of source-based taxation and complicates attributing taxing rights.
What the report covers
IATA's report examines the evolving international tax governance framework affecting global aviation. It focuses on how multiple organizations (OECD, UN bodies, ICAO) simultaneously develop tax rules, and how recent developments including the OECD/G20 BEPS project and UN Framework Convention negotiations threaten established principles for taxing international air transport income. The report argues that fragmentation and misalignment risk double taxation, compliance burdens, and economic damage.
Key findings
For more than 50 years, ICAO's Policies on Taxation in the Field of International Air Transport (Doc 8632) and Article 8 of Model Tax Conventions have established that international air transport profits should be taxed exclusively in the airline's State of residence or effective management. This framework has successfully prevented double taxation and maintained fair competition across the global air transport network.
The 2025 revision of Article 8 of the UN Model Tax Convention represents a fundamental shift, introducing source-based taxation as the preferred principle with residence-based taxation as secondary. This departure creates particular challenges for aviation because airlines operate integrated global networks spanning multiple jurisdictions, making strict source attribution impractical and economically distortive.
International tax governance is fragmenting through multiple simultaneous initiatives: OECD/G20 BEPS project, revisions to UN Model Tax Convention provisions, and ongoing negotiations for a binding UN Framework Convention on International Tax Cooperation. While these aim to strengthen tax cooperation and inclusiveness, they risk creating overlapping rules, conflicting interpretations, and increased administrative complexity without sector-specific consideration.
Air transport exhibits high operational fungibility that undermines source-based taxation logic. Aircraft and capacity are mobile and redeployable across routes and jurisdictions; revenue and income lack a single fixed 'source' location unlike manufacturing; and value depends critically on global network effects rather than individual segments. These factors make geographic revenue attribution administratively complex and economically irrational.
The report calls for ICAO and IATA to receive formal roles in international tax forums, enhanced government coordination, explicit carve-outs for sectors governed by existing international frameworks, and reinforcement of the legal status of ICAO's taxation principles. Preserving residence-based taxation and harmonised frameworks is described as strategically important for the global economy, not merely industry preference.

Why it matters
DMOs & destinations
Tax governance fragmentation and double-taxation risks directly affect airline operating costs and route viability, potentially reducing connectivity to smaller or less-profitable destinations. Destination competitiveness depends on stable, low-cost air access; inconsistent taxation frameworks increase airline costs and may prompt network reductions, particularly affecting peripheral or developing-market destinations reliant on international air services.
Hotels & hospitality
International tourism depends fundamentally on stable, efficient global air transport networks. Increased airline compliance costs, double taxation, and route unprofitability from fragmented tax regimes reduce flight capacity and raise fares, dampening demand for overnight stays. Hotel operators in regions with lower domestic demand rely heavily on international arrivals; tax-driven reductions in connectivity directly impact occupancy and revenue.
Travel tech & distribution
Volatility in airline profitability and capacity stemming from tax uncertainty cascades through distribution channels and pricing power. GDSs, booking platforms, and aggregators depend on reliable airline supply and competitive pricing; tax-driven cost increases and route cutbacks reduce inventory and widen profit margins, increasing consumer friction and potentially shifting volume to untraditional channels or suppressing overall booking volumes.
Methodology and limits
