We document that in semiformal economies, banks lend to tax-evading individuals based on the bank's assessment of the individual's true income. This observation leads to a novel approach to estimate tax evasion. We use microdata on household credit from a Greek bank, and replicate the bank underwriting model to infer the banks estimate of individuals' true income. We estimate that 43%-45% of self-employed income goes unreported and thus untaxed. For 2009, this implies 28.2 billion euros of unreported income, implying foregone tax revenues of over 11 billion euros or 30% of the deficit. Our method innovation allows for estimating the industry distribution of tax evasion in settings where uncovering the incidence of hidden cash transactions is difficult using other methods. Primary tax-evading industries are professional servicesmedicine, law, engineering, education, and media. We conclude with evidence that contemplates the importance of institutions, paper trail and political willpower for the persistence of tax evasion. * We thank our referees and the editor for many insightful comments and useful suggestions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
