We estimate firm-specific EMTRs and related user cost of capital (UCC) measures allowing for shareholder-level taxation using data for 2000-2010 from the Longitudinal Business Database. Examining distributions of various UCC measures we find substantial firm-level heterogeneity, systematic changes as a result of tax reforms between 2004 and 2011, and systematic differences between foreign-owned and domestically-owned firms. Choices among alternative UCC measures make a difference to interpretations.
