Global Tax Deal Faces Roadblocks From Hungary, Congress

U.S. and European officials are trying to inject fresh momentum into a global drive for a minimum corporate tax rate, but they are finding it difficult to navigate around a series of roadblocks, namely Democrats’ narrow margins in Congress and consequential objections from Hungary.

Nearly 140 countries agreed last year to impose a 15% minimum tax on large companies, paving the way for the most significant overhaul of international tax rules in a century. Getting to that point took years of negotiations that often seemed close to collapse. Now, eight months later, there has been little progress on changing national laws to implement the tax.
