Abstract

Country-specific origin-based profit taxes are marked by profit shifting and tax competition (see Chapter 6). Incentives for profit shifting can be mitigated, but not eliminated, by stricter rules and strengthening tax administration, while coordination can reduce the scope of tax competition but is hard to agree on (Chapter 11). Moreover, tighter anti-tax-avoidance rules often raise compliance and administrative costs and may intensify tax competition (Chapter 9).
