April 22, 2026 | Global Minimum Tax Coordination After the Side-by-Side Agreement 

After intense negotiations, nearly 150 jurisdictions agreed in January to a side-by-side package designed to accommodate the United States’ concerns about the global minimum tax framework. The agreement provides a coordinated safe harbor for certain multinationals and introduces added simplifications to reduce compliance burdens and enhance certainty. Supporters have described the package as a pragmatic step that reinforces cooperation and stability in international tax rules. Will the side-by-side approach provide a durable foundation for implementation, or does it signal a more flexible, country-specific phase of global minimum tax coordination?
