Law 2586 of 2026 (Official Gazette 53,527 of June 19, 2026) adopted the customs penalty and forfeiture regime and repealed Decree-Law 920 of 2023 (art. 114); for operations started before it took effect, article 112 keeps the rule in force at the start, without prejudice to the more favorable rule. On errors in the import declaration, article 15 distinguishes several scenarios: partial errors or omissions in the serial number or wrong or incomplete descriptions that do not involve different goods, a change of subheading with higher taxes or a breach of restrictions, with a fine of 15% of the FOB value per declaration (num. 15.2.2.4), which does not apply if the correction declaration is filed within 30 business days after the date on which DIAN detected the error; inaccuracies or errors that cause an underpayment of customs taxes, with a fine of 10% of the taxes left unpaid per declaration (num. 15.2.2.6); and inaccuracies that lead to a breach of legal or administrative restrictions or quotas, with a fine of 600 UVT per operation (num. 15.2.2.10). In addition, article 22 declares as non-sanctionable formal errors those that do not affect the assessment of taxes, penalties or redemption, the restrictions or customs control, except for the wrong or incomplete serial number or description, which follow num. 15.2.2.4.
Correcting and accepting the infraction are two different tools. The voluntary correction declaration (Decree 1165 of 2019, art. 296) serves only to remedy the errors the rule lists (tariff subheading, rates, exchange rate, penalties, arithmetic operation, modality, preferential treatments, FOB value, freight, insurance, other expenses, adjustments and customs value), is available within the three-year finality period of article 188 and, if voluntary, only once; it requires assessing and paying the additional taxes, the interest and the corresponding penalty. When the description is wrong or incomplete and the goods are not different, there is also the legalization declaration with redemption (arts. 290, 291 and 293, num. 2, of the same decree). Acceptance of the infraction (allanamiento), on the other hand, is the written acknowledgment of the infraction in order to reduce the fine (Law 2586, art. 19): no penalty if the acknowledgment is voluntary and made without DIAN intervention before the Special Customs Request is notified (not applicable to very serious infractions); fine at 20% if acknowledged before that request; at 40% after notification and before the decision on the merits; and at 60% within the period to appeal that decision. Before getting there, article 5 allows DIAN to invite the user to correct within the month following the communication; not answering does not generate a penalty, but opens the way to the request. When there is a seizure risk, and how it is contested, is explained below and in DIAN seizure and forfeiture.
