Article 434A of the Colombian Penal Code (introduced by Law 1819 of 2016 and amended by Article 69 of Law 2277 of 2022, which lowered the threshold to 1,000 SMMLV) criminalizes the omission of assets or inclusion of nonexistent liabilities: whoever omits assets, declares a lower value of assets, or reports nonexistent liabilities with the intent to defraud or evade in tax filings, for an amount equal to or exceeding 1,000 SMMLV defined by an official assessment issued by the tax authority, incurs imprisonment from 48 to 108 months. Omitted or undervalued asset amounts are appraised under the wealth valuation rules of the Tax Statute, while nonexistent liabilities are evaluated at their reported value. The statute establishes graduated sentence enhancements: if the value exceeds 2,500 SMMLV but remains below 5,000 SMMLV, prison penalties increase by one third; if it exceeds 5,000 SMMLV, penalties increase by one half. Article 434B of the Penal Code punishes tax fraud and evasion (failing to file, omitting income, reporting fictitious costs, or claiming improper tax credits) between 100 and 2,500 SMMLV with 36 to 60 months of imprisonment and identical graduated increases, alongside the failure to remit collected taxes under Article 402.
The statutory design conditions criminal prosecution directly upon tax determination: the amount must be conclusively 'defined by an official assessment of the tax authority'. Paragraph 1 of Articles 434A and 434B provides an essential procedural safeguard: criminal proceedings proceed only if administrative appeals are not currently pending, or when there is no reasonable interpretation of applicable law, provided that declared facts and figures are complete and true. Furthermore, DIAN may request the initiation of criminal proceedings through a special petition issued by a committee led by the Director General or their designee. In turn, Paragraph 2 dictates that criminal proceedings are extinguished up to two (2) times when the perpetrator pays all corresponding taxes, penalties, and interest. If the principle of opportunity or extinguishment by payment has already been granted up to twice under Articles 434A or 434B, subsequent payment will not extinguish criminal proceedings nor allow principle of opportunity, granting only a penalty reduction of up to one half.
