Specifically, I test whether adoption of IFRS facilitates income tax-motivated profit shifting by multinational entities (MNEs). MNEs often justify transfer prices to tax authorities by benchmarking intercompany profit allocations against a range of profit rates reported by economically comparable, independent firms that use similar accounting standards. A larger set of qualifying benchmark firms resulting from IFRS adoption could allow opportunistic managers to support more tax-advantaged transfer prices. I use a database of EU unconsolidated financial and ownership information to identify tax-motivated income shifting over 2001 to 2010. I estimate a statistically and economically significant 17.5 percent tax-motivated change in reported pre-tax profits following affiliate IFRS adoption, relative to no change in income shifting behavior for non-adopters. The magnitude of this effect increases in expansions to the set of potential benchmark firms upon affiliate IFRS adoption.application/pdfen-USInternationalIFRSTaxIncome shifting2013-10-25
