The paper focuses on electronic record of sales, a tool enabling continuous monitoring and control of declared sales of business entities. Such systems have been recently gaining popularity in European countries. The objective of the paper is to analyse the possible use of electronic record of sales for a fairer redistribution of shared taxes according to the place where the taxable income was earned. We do not consider the current situation to be entirely fair, as sales may be realized in the whole territory of the country. However municipalities that help businesses achieve their income are not fairly rewarded for doing so. This usually gives larger municipalities an advantage at the expense of smaller ones. Currently, the tax administration has sufficient technical equipment to be able to identify the place where the revenue was received.
