Tax evasion is one of the main obstacles to the development of the economy. Measures and tools to prevent tax evasion will ensure a level playing field for competitors from different sectors and guarantee government resources for social programs and investments.

One of ETCO's priority projects is the fight against the Contumaz Tax Debtor, which, unlike the tax evader, issues a note and notifies the tax authorities that it has sold its products, but does not collect taxes on it and uses this illicit advantage to reduce its prices and gain market unfairly.

Understand what the default debtor is and what we can do to combat it
