Criminal tax complaints may rest on one of three offenses in the Penal Code (Law 599 of 2000). Article 402 punishes the omission of the withholding or collecting agent: withholdings, VAT, or national consumption tax not remitted within two months after the date set to file and pay, with 48 to 108 months of prison and a fine of twice the amount not remitted, capped at 1,020,000 UVT. Article 434A punishes omitting assets or including non-existent liabilities, with intent to defraud or evade, when the amount is equal to or above 1,000 SMMLV, with 48 to 108 months of prison and increases of one third or one half depending on the value. Article 434B punishes tax fraud or evasion (failing to file, omitting income, including non-existent costs or expenses, or claiming improper tax credits, withholdings, or advance payments) when the lower tax payable or higher refund balance is between 100 and 2,500 SMMLV, with 36 to 60 months of prison and the same increases by amount. Under 434A and 434B, the amount is defined by official assessment.
That is why the administrative and criminal fronts are connected. Under paragraph 1 of Articles 434A and 434B, criminal action proceeds provided that no administrative appeals are pending, or when there is no reasonable interpretation of the applicable law, provided that the declared facts and figures are complete and true. DIAN may request the start of criminal action through a special petition from a committee chaired by the Director General or their delegate. And there is a path to extinguishment: under paragraph 2, criminal action is extinguished up to two times when taxes, tax penalties, and interest are paid; if the principle of opportunity was already applied or the action was already extinguished twice by payment, payment only allows a reduction of the sentence of up to one half. Under Article 402, whoever extinguishes the obligation by payment or set-off with interest benefits from an inhibitory resolution, preclusion of the investigation, or cessation of proceedings, without prejudice to administrative penalties. Properly disputing the official assessment before DIAN is therefore part of the criminal defense.
