Tax planning, regulatory capital planning, and financial reporting strategy for commercial banks

We test whether banks' investment and financing policies canbe explained by tax status. We document changes in bank holdingsof municipal bonds in response to changes in tax rules relatingto deductibility of interest expense. We also document an associationbetween banks' marginal tax rates and their investment and financingdecisions, which is consistent with the existence of tax clienteles.However, banks do not sort themselves perfectly into investmentand financing clienteles because of adjustment costs. We positspecific types of transaction-cost impediments to tax planning,and document that banks apparently trade off these costs againsttax-planning benefits.
