Explainer for the explainer: * the minimum corporate tax rate is 15% * countries don't have to increase their corporate tax rate to 15% * home countries can "top-up" until the effective tax rate is 15% * Tax havens can still exist, but the incentive for multinational firms to move their profits to tax havens goes away because their home countries just top-up until effective tax rate is 15%. Inversion prohibitions are suggested. Inversions happen when companies move to tax havens while keeping their management and substantial operations in their previous home country.
