GIF: A Web-based System for Tax Management and Fiscal Intelligence in Municipal Tax Administration

摘要

This paper presents a system for tax management and fiscal intelligence, called GIF. The GIF system includes the modules NFSe (e-ST: electronic Services Tax) and DMSe (e-STI: electronic Services Tax Information), which consists of web applications oriented to the interaction of independent contractors with the municipal tax administration in order to release them from further fiscal obligations. The web applications provide features which allow the contractors to submit their electronic municipal service taxes, including the payment of the ISSQN tax, as well as to submit general information on the their monthly municipal service taxes. Another GIF module is the ATRe (e-TA: electronic Tax Analysis), which eases the work of the tax authorities in identifying possible tax evasions by means of data mining techniques applied on the information submitted by the contractors. The GIF system has been deployed in municipal administrations in Brazil with very impressive results.
