Impact of CFDI on tax evasion

 El impacto del CFDI en la evasión fiscal

In a worldwide ranking of e-invoicing expansion, Mexico would top the ratings. In 2015, the Tax Administration Service (SAT) rolled out the obligation to issue CFDI for all taxpayers, which finally led to massification of this technology. But what was the objective?

Although e-invoicing entails benefits such as encouraging innovation, the elimination of the paper in companies or economic cost savings, Mexico’s tax authority opted for this initiative to achieve two great goals: to simplify compliance and, most of all, to fight tax evasion. Now, a report published by the Monterrey Technological and Higher Education Institute concludes that introducing the CFDI has had a significant impact on tax evasion, one of the main economic issues dogging the country.

According to the Monterrey Technology Institute’s study, the obligation to issue CFDI, which came into force in 2015, led to growth in Income Tax (ISR) to the tune of 6,6% for legal entities and 21.3% for individuals. This is the most widely collected tax for the SAT, hence the importance of avoiding fraud.

  • The first of these guidelines directly affects the mandatory use of version 3.3 and the migration to the new schema. Version 3.3 will go into effect on July 1, 2017, however, version 3.2 may continue to be used to issue invoices until November 30, 2017. As of December 1, 2017, the only version valid for issuing electronic invoices will be version 3.3.
