As a part of an international effort to end tax avoidance, the Organization for Economic Co-operation and Development proposed a global minimum effective corporate tax rate of 15 percent for large multinational corporations. This research examines the obstacles that will need to be overcome to implement this legislation. More specifically, will this legislation ever be enacted in the countries where it matters? If so, when? Can the world unite to implement the largest global tax overhaul in recent memory? Who will it affect? Will corporations change where they do business because of this new tax? How will tax firms deal with this new legislation? The results of this research indicate that unless this is brought to the forefront of all legislative bodies, the OECD will not reach their goal of implementing their two-pillar plan by 2024. The research also found that the three major stakeholders involved will have to overcome enormous obstacles to prepare for this revolutionary overhaul. These findings have important implications for large multinational corporations, governments worldwide, the accounting industry, and the global economy as a whole. Tax firms have begun preparations for if/when the global minimum tax is implemented, but some issues cannot be addressed until countries begin drafting this legislation. This research indicates that this legislation can only be enacted and succeed if stakeholders collaborate to an extreme extent.
