Habit Persistence in Effective Tax Rates: Evidence Using Australian Tax Entities

This paper is the result of work being undertaken as part of a collaborative research program entitled 'The Performance of Australian Enterprises: Innovation, Productivity and Profitability'.

We would like to thank Dr Arif Syed of the ATO for some helpful comments.This paper uses administrative data from the Australian Tax Office, to model the effective tax rates (ETRs) of large Australian corporates. The extent to which there is any habit persistence in ETRs is also examined. The results suggest that unobserved entity heterogeneity is important in explaining ETRs. In terms of observed heterogeneity, entity size, level of leverage, capital intensity, foreign income and R&D, are all important explanators of ETRs. There is also evidence of a significant amount of habit persistence, implying that ETRs converge monotonically towards the statutory rate of corporation tax
