Authors examine the impact of potential repatriation taxes on U.S. multinationals’ pre-2018 tax planning actions and capital structure policies. We construct a proxy for exogenous changes to repatriation tax rates and find that repatriation-tax-sensitive multinationals are more likely to pursue tax-free repatriation techniques, with examples provided. We also find a positive relationship between repatriation tax increases and both bond issuance and debt ratios, but only for repatriation-tax-sensitive multinationals. These results are concentrated in firms with lower costs of debt capital, while no increased likelihood of inversions is found. Our findings have important implications for current and proposed U.S. tax policies.
