Tax lotteries are seen as ways to relatively easily augment public revenue while also increasing compliance. Tax lotteries are constructed so that consumers are nudged to ask for a receipt when making a purchase. This receipt contains information so that it can also be used as a lottery ticket with the possibility of winning prizes. Such tickets also leave traces of transaction records so that revenue authorities can audit vendors. Given this background, the aim of this paper is to provide a broad, multi-methodological and socio-economic assessment of Georgia’s tax lottery experience in 2012. Our assessment aims to describe the design of the lottery and its functioning in practice, to evaluate how the introduction of the tax lottery influenced the effectiveness of tax administration in Georgia at the country, regional, and firm level and to investigate Georgian citizens’ views of the Georgian Revenue Service (GRS) and if tax compliance was improved by the tax lottery. Economic assessment, based on data from 2012 and 2013 on weekly transactions per cash register, using three econometric specifications show that during the lottery weeks, there is a significant increase in the aggregate weekly sales compared to the non-lottery weeks. The number of cash registers reporting their income and the average weekly sales are also higher in lottery weeks.
