Should nations prioritize international cooperation on corporate tax standards to stabilize their public finances?
The OECD convened its 18th meeting of the Inclusive Framework on Base Erosion and Profit Shifting in Paris to evaluate international tax standards. During the assembly, Guatemala officially joined the group as its 148th member.
Why it matters
Global corporate tax reform aims to stabilize public finances amid rising debt-to-GDP ratios and slowing worldwide economic growth. These standardized rules seek to prevent profit shifting and ensure major multinational enterprises pay appropriate taxes.
Approximately 65 jurisdictions have implemented global minimum tax rules, which currently cover more than 90% of in-scope multinational enterprises. These measures are projected to reduce profit shifting by 25% to 50% globally.
The players
OECD
The Organisation for Economic Co-operation and Development is an international group that coordinates policies to promote global economic growth and prosperity.
Guatemala
This Central American nation recently became the 148th country to join the G20-backed effort to reform international tax rules.
The details
The framework has successfully reduced the sensitivity of profit booking to tax rates by up to 40% compared to 2015 levels, while profit-to-employee ratios in investment hubs have fallen by 27%. To support this transition, the OECD has provided specialized training to nearly 150,000 tax officials worldwide.
Timeline
2015 served as the baseline year for profit sensitivity estimates.
The first meeting of the Inclusive Framework took place in 2016 in Kyoto.
Guatemala joined the framework as its 148th member in January 2026.
The 18th plenary meeting occurred in Paris on October 28, 2026.
Macro View
This assembly marks a continuation of the standards set by the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting. The ongoing implementation follows a decade-long shift toward harmonizing international tax policies to counter legacy profit-shifting gaps.
The implementation of a global minimum tax is expected to increase total corporate tax revenues by 3% to 5% annually for participating countries. These shifts may eventually impact national budgets and the availability of public funding for local services.
The takeaway
Ongoing multinational tax reforms are steadily closing gaps that previously allowed enterprises to minimize tax liabilities. Countries are increasingly aligning with these standards to secure sustainable revenue streams in a constrained global economy.
