Title: A decomposition algorithm for computing income taxes with pass-through entities and its application to the Chilean case.

Authors:  Javiera Barrera · Eduardo Moreno · Sebastián Varas K.

Abstract:

Income tax systems with “pass-through” entities transfer a firm’s in- come to the shareholders, which are taxed individually. In 2014, a Chilean tax reform introduced this type of entity and changed to an accrual basis that dis- tributes incomes (but not losses) to shareholders. A crucial step for the Chilean taxation authority is to compute the final income of each individual, given the complex network of corporations and companies, usually including cycles between them. In this paper, we show the mathematical conceptualization and the solution to the problem, proving that there is only one way to distribute income to taxpayers. Using the theory of absorbing Markov chains, we define a mathematical model for computing the taxable income of each taxpayer, and we propose a decomposition algorithm for this problem. This allows us to compute the solution accurately and with the efficient use of computational resources. Finally, we present some characteristics of the Chilean taxpayers’ network and computational results of the algorithm using this network.
