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

(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

(Some) Possible Reforms

• Incremental reforms– Lower the statutory rate– Repeal check the box– Administration budget proposals and other

reforms of current law

Evaluating the Reforms

• Key considerations– Repatriation tax?– Income shifting incentives?– Tax revenue? – Simplicity?– Location incentives for tangible and intangible capital?– Expatriation incentives?– Transition rules?

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

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
