21. Problems with current system Income shifting and its effects on investment location decisions and revenue Lockout effect of repatriation tax and associated costs of avoidance Complexity May put U.S. multinationals at a competitive disadvantage Raises little revenue

22. (Some) Possible Reforms Fundamental reforms – Worldwide taxation with repeal of deferral – Dividend exemption Grubert and Altshuler (2012): combine dividend exemption with a minimum tax of 15% – Formulary apportionment

23. (Some) Possible Reforms Incremental reforms – Lower the statutory rate – Repeal check the box – Administration budget proposals and other reforms of current law

24. Evaluating the Reforms Key considerations – Repatriation tax? – Income shifting incentives? – Tax revenue? – Simplicity? – Location incentives for tangible and intangible capital? – Expatriation incentives? – Transition rules?

25. Effective Tax Rate Simulations* Home country (U.S.) with tax rate of 30% Low tax country (5% tax rate), high tax country (25% tax rate), tax haven (0% tax rate) A discrete high tech investment in low tax country based on U.S. R&D A routine investment in high tax location Income shifting possible but is not costless *From Grubert and Altshuler, 2012, “Fixing the System: An Analysis of Alternative Proposals for the Reform of International Tax”

27. Conclusions Look for reforms that make improvements to the current system across many dimensions including lockout effect, income shifting, competitiveness, and complexity Goals may not be in conflict – A minimum tax combined with dividend exemption may have advantages over repeal of deferral and dividend exemption alone, and reduce their shortcomings
